SIX STROKE ENGINE...
 In recent news there are huge changes are occur recently a six stroke engine is unvailed by an English mechanic. The mechanism behind it was just an assembly of a two stroke and four stroke engine with the attachment of ports, so that the flow of charge is maintain that there is no attachment of cam and valves.
                           There is the mechanism continues when the both piston revolves  and the crankshaft rotates one revolution in case of two stroke piston and two revolution in four stroke piston. the efficiency of the engine is much better then four stroke engine because there is the compression of the fuel is twice because there are two piston acting on it. so there is the no of stroke are
                                                2stroke+4 stroke=6stroke.
the power produced by these engine area bit low as there is the displacement and the clearance is also increase.The displacement of these engine (area of cubic  capacity also increase.

TEN WAYS TO MAINTAIN THE EFFICIENCY OF BIKE
For an Indian biker, achieving the highest possible fuel efficiency for any bike is a constant endeavour. The answer is to keep learning so that you do not forget the key points. I have already posted some tips for inproving your bike’s mileage. Here are some factors which affect fuel efficiency. I hope you find it useful.

Aerodynamics: Aerodynamics do not make much of a difference in Indian motorcycles. However faired bikes like the Karizma do offer a marginally more aerodynamic stance, but that’s when the rider is firmly tucked in behind the fairing.



Gadgetry: Aids that draw power from the engine and battery naturally result in more consumption of fuel. This includes over size horns, additional headlights etc. Oversize and wider tyres also increase drag and reduce the fuel efficiency.

Highway Riding: Lower capacity bikes aren’t capable of high speeds on the highway and run out of breath over 80kmph, cruise at 60kmph on such bikes. Larger capacity motorcycles are comfortable cruising at 80kmph speeds but ensure that the engine is not stressed which will ensure optimum mileage. Avoid shifting up and down and try to maintain a sate and constant cruising speed in top gear. Do not open the throttle wide open, a part open throttle is the most efficient throttle opening. Plan overtaking moves well in advance so that you don’t have to brake nor accelerate hard to pass vehicles. Reduce speed by easing off the throttle rather than by using the brakes. Smoothness is the key, in acceleration, in braking and in maintaining speed which will deliver the best mileage.



Weight: Unnecessary accessories like excessively heavy crash guards, enveloping guards on scooters, oversize horns all add to the weight and consequently reduce fuel efficiency. On a 100kg bike even a 5kg increase will have an adverse effect on fuel consumption.

Fuel: Always buy fuel in the morning as it is sold by volume and expands during the day when it gets hot.

Cleanliness: Any leaks will be immediately noticeable on a clean bike and in a roundabout way will have an effect on the fuel efficiency. Dirt on the chain, in between moving parts etc will increase drag and consequently lower fuel efficiency.

Octane: Check the owners manual on what quality of petrol your bike requires. Modern bikes run a very high compression ratio and need high octane fuel (93 octane fuel is available in the metros) to run without knocking. Octane boosters (recommended on the Pulsar) also do a good job of controlling knock. However on engines designed to run on 83 octane petrol using higher octane rating petrol or octane boosters will have no effect other than lightening your wallet. Remember that higher the octane rating higher the price per litre.

Tanking Up: Do not tank up right to the brim. Not only is there a chance of spillage while filling up, petrol also expands with heat and can overflow. Filler caps on many bikes do leak once the rubber seal hardens and cracks. Tank up from busy and well know fuelling stations where quality and quantity are assured.

Engine Efficiency: Specific output is the most reliable indicator of engine efficiency. Specific output is defined as the ratio between power and displacement and higher the specific output in terms of PS/litre the more efficient the engine is. Lower emissions are also a sign of a more efficient engine. For example an engine designed to meet Euro II norms will be more efficient than a Euro I compliant engine. However an efficient engine will not necessarily translate into better fuel efficiency as it might be powering a heavier motorcycle and geared more for performance.

THE TECHNOLOGY BEHIND NITRO BOOOSTERS


MANY OF US HAVE SEEN THE NFS BOOSTERS SO HOW IT WORKS TAKE A LOOK........
Every one of you must have heard of nitro boosters, alternatively known as NOS. The main dilemma comes to mind when you think of their working. Exactly how do nitrous boosters work? 
One can fit nitrous to their bikes in order to gain more speed and torque. Though it is not common. NOS cylinders contain Nitride-oxide that makes your engine smoother i.e. it nourishes your engine with regards speed and power. The more Nitrous you use the more powerful your bike becomes.
Basically NOS cylinders contain a handful of gasses like ammonia nitrate, nitrous oxide, nitrogen and various other variations of nitrogen. These various gasses fuse inside the combustion chamber at a temperature of 240 degrees.
The gas produced at such high temperatures produce smoke, steam and results in more speed and power. So for obvious reasons when you see bikes with nitrous leading the race do not be surprised. In bikes with nitrous what basically happens is that the system delivers more oxygen in the engine at regular intervals.
The oxygen delivered at regular intervals combines with the nitrogen gas and other gasses and burns the fuel at a faster pace; this produces more power and efficient torque.
Whenever the oxygen is taken in to the engine, it combines itself with the nitrogen stored in liquefied form and this will drop the temperatures to lower levels at the intake charge. In simple terms this means that the engine becomes more capable of burning more fuel and air simultaneously. The temperature downfall at the intake manifold will result in increases power and fuel available to engine.
The power of your engine increases 100 to 300% from the current level. So unless you have good high end bikes nitrous cannot be used. It can even destroy your engine if it proves to be incompatible.
This kind of NOS operations are supported only when the bikes are mechanically transformed to fit the nitrous requirement. Thus, it can be stated that NOS can eventually turn your bike to a speed jet but one needs to be careful while installing them. Be careful that your bike is properly modified to compile with such high level mechanics.

So honda keep going on and give the masterpiece.....

HONDA`S Combi Break System

Combi Brake is a mechanical technology to distribute the braking force between front wheels and rear wheels by simply pressing the left brake lever only.
Combi Brake With this technology, the bike will stop in a shorter braking distance is more leverage with a uniform braking on both front and rear wheels together. The weight of the braking power of its core will be automatically split between front and rear wheels as needed on the motor braking.
Well Combi Brake is very suitable for use by novice riders as well as the weaker sex. Where with the Combi Brake technology will help novice riders to perform braking like a motorist who was Pro. Combi Brake will take over capability of the pro riders at the time of distribution of braking on the front and rear wheels, so that the novice rider, would be greatly assisted by the Combi Brake.


As for how the Combi Break System is as follows:
When the left brake lever (1) is pressed, then the equalizer style will work to distribute the pressure force had to be two: one to brake on the rear wheels (2) and the other toward the tipping lever (3) to suppress the knocker that will push the hydraulic piston (4) which of course will react to activate the front brake discs. In this process of braking power will be automatically divided on both the front and rear wheels. Well bottom line, however, lies in the mechanism that will distribute the force equalizer based on the moment of force due to differences in the length of the lever arm equlizer cable.
      A six stroke mechanisum by a mechanic.        

this age of technology automobile industry it is just going on thebest it can get the technology. The technology is movong forward on a systematic way. Firstly we have introduce the two stroke engine. After process the engine is modified to four strokes and the setup is just going ahead.
Under the hood of almost all modern automobiles there sits a four-stroke internal combustion engine (ICE). Though the efficiency of the design has been improved upon significantly in the intervening years, the basic concept is the same today as that used by the first practical four-stroke engine built in the 1870s. During every cycle in a typical car engine, each piston moves up and down twice in the chamber, resulting in four total strokes... one of which is the power stroke that provides the torque to move the vehicle. But the automotive industry may soon be revolutionized by a new six-stroke design which adds a second power stroke, resulting in a much more efficient and less polluting alternative.

In a traditional ICE cycle, 1) the fuel/air valves open as the piston moves down, which draws air and fuel into the chamber; 2) the valves close as the piston moves back up, putting the air/fuel mixture under pressure; 3) the mixture is then ignited, causing a small explosion which forces the piston back down, which turns the crank and provides the torque; and finally 4) the exhaust valves open as the piston moves back up once again, pushing the byproducts of the fuel explosion out of the chamber. This leaves the piston back in its starting position, ready for another cycle. This process is repeated thousands of times per minute.
The clever new six-stroke design was developed by 75-year-old mechanic and tinkerer Bruce Crower, a veteran of the racing industry and a the owner of a company which produces high-performance cams and other engine parts. He had long been trying to devise a way to harness the waste heat energy of combustion engines, and one day in 2004 he awoke with an idea which he immediately set to work designing and machining. He modified a single-cylinder engine on his workbench to use the new design, and after fabricating the parts and assembling the powerplant, he poured in some gas and yanked the starter rope. His prototype worked.
His addition to the ICE design is simple in principle, yet a stroke of genius. After the exhaust cycles out of the chamber, rather than squirting more fuel and air into the chamber, his design injects ordinary water. Inside the extremely hot chamber, the water immediately turns to steam-- expanding to 1600 times its volume-- which forces the piston down for a second power stroke. Another exhaust cycle pushes the steam out of the chamber, and then the six-stroke cycle begins again.
Besides providing power, this water injection cycle cools the engine from within, making an engine's heavy radiator, coolant, and fans obsolete. Despite its lack of a conventional liquid cooling system, his bench engine is only warm to the touch while it is running.


hats off to him.......

           How does abs works.        



ABS MECHANISM 

anti-lock braking
An anti-lock braking system, or ABS is a safety system which prevents thewheels on a motor vehicle from locking up (or ceasing to rotate) while braking.
A rotating road wheel allows the driver to maintain steering control under heavy braking by preventing a skid and allowing the wheel to continue interacting tractively with the road surface as directed by driver steering inputs. ABS offers improved vehicle control and decreases stopping distances on dry and especially slippery surfaces. However, on loose surfaces like gravel and snow-on-pavement, it can slightly increase braking distance while still improving vehicle control.
Since initial widespread use in production cars, anti-lock braking systems have evolved considerably. Recent versions not only prevent wheel lock under braking, but also electronically control the front-to-rear brake bias. This function, depending on its specific capabilities and implementation, is known as electronic brake force distribution, (EBD), tractioncontrol system , emergency brake assist or electronic stability control.
Four-wheel ABS





The four-wheel ABS or Anti-lock Braking System is designed to help the driver maintain steering control during hard braking, especially in slippery conditions. How it works:
Imagine, you are driving a car without ABS on a slippery road (e.g. after a rain or snow). Suddenly, you notice something on the road right in front of you. You hit the brakes, and try to turn aside, but the steering doesn't work; the car just skids out of control (see the picture). Why, because all the wheels are locked up while you are holding down the brake pedal. As a result, you lose the ability to steer the vehicle.
The four-wheel ABS can help in situations like this. It prevents the wheels from locking up, helping you maintain steering control during braking. In a similar situation, driving a car equipped with four-wheel ABS, it would be easier for you to steer your vehicle while braking.

Essential to know:- The four-wheel ABS system can help to slightly reduce the braking distance in some situations. However, under certain conditions (e.g. on loose snow or gravel), the braking distance may be longer. The main purpose of ABS is to help the driver maintain steering control during hard braking.
- Some trucks may have the two-wheel ABS system that controls only rear wheels. The rear wheel ABS system does not help to maintain steering control during braking. To gain full advantage of the ABS system you need to know what type of ABS you have in your vehicle and operate it correctly. Check your owner's manual for details.
- Good tires play an important role; for example, if the car has bald or wide sport tires the ABS can hardly prevent it from skidding on the snow
How the actual ABS system works
Major components of the typical ABS system include four speed sensors (one at each wheel), an electronic control unit (ABS computer) and a hydraulic control unit (see the picture). The ABS computer constantly monitors the signal from each wheel speed sensor. When it senses that any of the wheels are approaching lock up during braking, the ABS computer sends the signal to the hydraulic control unit, which modulates the braking pressure for a corresponding wheel(s) preventing it from locking up.
When the ABS is activated, it feels like rapid brake pedal pulsation with a buzzing noise, which is normal.
ABS system problemsIf the ABS light comes on while driving, there is a problem with your ABS system and you need to visit your dealer as soon as possible.
Bugatti veyron engine turbocharging process.....



Creating the Engine

Bugatti did two things to create a compact engine capable of producing 1,000 hp. The first and most obvious thing isturbocharging.
If you have read how the turbocharging works, you know that one easy way to make an engine more powerful without making the engine bigger is to stuff more air into the cylinders on each intake stroke. Turbochargers do that. A turbo pressurizes the air coming into the cylinder so the cylinder can hold more air.
If you stuff twice as much air in each cylinder, you can burn twice as much gasoline. In reality, it's not quite a perfect ratio like that, but you get the idea. The Bugatti uses a maximum turbo boost of 18 PSI to double the output power of its engine.

Therefore, turbocharging allows Bugatti to cut the size of the engine from 16 liters back down to a more manageable 8 liters.
To generate that much air pressure, the Bugatti requires four separate turbochargers arranged around the engine.
The second thing Bugatti engineers did, both to keep the RPM redline high and to lower lag time when you press the accelerator, was to double the number of cylinders. The Bugatti has a very rare 16-cylinder engine.
There are two easy ways to create a 16-cylinder engine.
  • One way would be to put two V-8 engines in-line with each other. You connect the output shaft of the two V-8s together.
  • Another would be to put two in-line 8-cylinder engines beside one another.
The latter technique is, in fact, the way Bugatti created its first 16-cylinder cars in the early 20th century.
For the Veyron, Bugatti chose a much more challenging path. Essentially, Bugatti merged two V-8 engines onto one another, and then let both of them share the same crankshaft. This configuration creates the W-16 engine found in the Veyron. The two V's create a W. You can see exactly how this looks in a set of beautiful videos available on the Bugatti website.
Then, Bugatti started piling on features to make the engine even better and better for the purpose to give the consumes as there best as they can do........

Electrohydraulic manual transmission


Electrohydrolic manual transmission is a type ofsemi-automatic transmission system, which uses an automated clutch unlike conventional manual transmissions where the driver operates the clutch. The clutch is controlled by electronic computers and hydraulics. To change gears, the driver selects the desired gear with the transmission shift lever, and the system automatically operates the clutch and throttle to match revs and engage the clutch again. Also, many such transmissions operate in sequential mode where the driver can only upshift or downshift by one gear at a time.
Depending on the implementation, some computer-controlled electrohydraulic manual transmissions will automatically shift gears at the right points (like anautomatic transmission), while others require the driver to manually select the gear even when the engine is at the redline. Despite superficial similarity, clutchless manual transmission differ significantly in internal operation and driver's 'feel' from manumatics, the latter of which is an automatic transmission (automatics use a torque converter instead of clutch to manage the link between the engine and the transmission) with ability to signal shifts manually.

USED IN ROAD CARS
In 1984, Isuzu introduced the "NAVi5", a semi-automatic gearbox with electronically controlled hydraulics, for their domestic-market Aska. Initially available with an automatic mode only, the later incarnations added a manual mode. It was operated with an H-pattern shift lever, not a sequential lever or paddles popular in today’s cars.
The most famous application of a sequential transmission on road-cars would be their use in someFerraris since the late-nineties, beginning with the F355 F1. Their system, the most current version of which is called "F1-Superfast," with shift times of 60 ms[1] is designed to serve as a link to their Formula One efforts. This technology has also trickled down to the cars of their sister company, Maserati where it is known as "Cambiocorsa". Alfa Romeo's Selespeed in 1999 was the first sequential transmission in a mainstream car, derived from the Ferrari system.[citation needed]
BMW offered a system simply called "sequential manual gearbox" (SMG) on the E36 M3, and later "SMG-II" on the E46 M3. The BMW SMG transmission has both automatic and manual shift modes. Inside the different modes there are different programmes, with six settings to control the upshift/downshift speed for manual operation, and five settings for automatic mode.
Later, the 3rd generation Toyota MR2 used Toyota's version, known as the "Sequential Manual Transmission" (SMT). Although it does not perform as well as the European-designed transmissions, Toyota's is the cheapest system to manufacture, and the MR2 is the least expensive car to possess a true sequential gearbox.[citation needed]
Finally, Volkswagen Group (parent owner ofLamborghini) introduced a sequential transmission to the Lamborghini Gallardo (E gear), and then adding it to the Audi R8 (R tronic).
BMW has since switched over to a Getrag dual clutch transmission in the latest M3, and Ferrari as well in 2009 with the California and 458 Italia.

ISR or Independent shifting rod is the new Transmission type bought on to the stage by Lamborghini. The new unit is laid out as a two-shaft transmission with seven forward gears and one reverse. For especially high durability, the synchronizing rings are made from carbon-fiber. The short shift times are the speciality of this kind of transmission.
What it makes different from a conventional transmission?
In a conventional manual gearbox, be it automated or fully manual, the gear wheels for, say, second and third gears are located side by side. When the driver wants to shift gear, the shifting sleeve with synchronizer unit is moved along the shifting rod from second gear through neutral to third gear. This requires twice the distance and twice the time – second gear has to be disengaged before third gear can be engaged.
This process is significantly shortened in ISR transmission – the gear wheels from the second and third gears are separate from each other and the shifting sleeves are actuated by independent shifting rods. Now the shifting process can run virtually in parallel – while one shifting rod is disengaging one gear, the second shifting rod can already engage the next gear. Because these movements partially overlap and the mechanical distances are considerably shorter, this facilitates a significant saving in shift time. Overall, the Lamborghini ISR transmission shifts around 40 percent faster than the e-gear transmission. And that is already one of the world’s fastest automated manual gearboxes.
What is inside?
The new transmission has four of these independent shifting rods, with sensors constantly monitoring their exact positions. They are operated via hydraulic actuators, with an extremely high system pressure of 60 bar ensuring the necessary operating speed. The system incorporates a total of seven hydraulic valves, with pressure supplied by an electric pump. The double-plate clutch is also hydraulically actuated. All system components are contained within one casing. The total weight of the transmission is only 70 kilograms – a distinct advantage, especially compared with the significantly heavier dual-clutch transmissions from the same category.
