Since the invention of the internal combustion engine, automotive engineers, speed junkies and racecar designers have been searching for ways to boost its power. One way to add power is to build a bigger engine. But bigger engines, which weigh more and cost more to build and maintain, are not always better. Another way to add power is to make a normal-sized engine more efficient. You can accomplish this by forcing more air into the combustion chamber. More air means more fuel can be added, and more fuel means a bigger explosion and greater horsepower. A turbo/supercharged engine produces more power overall than the same engine without the charging. Both superchargers and turbochargers do this. The difference between the two devices is their source of energy . TURBOCHARGER
basics. There is a huge interest in vintage snowmobiles and their “simple” two stroke power plants of yesteryear. There is a wealth of knowledge contained in this manual. Let’s journey back to 1973 and read the book that was the two stroke bible of that era. Decades have passed since I hung around with John and Jim. John and I worked for the same corporation and I found a 500 triple Kawasaki for him at a reasonable price. He converted it into a drag bike, modified the engine completely and added mikuni carbs and tuned pipes. John borrowed Jim’s copy of the ‘Two Stoke Tuner’s Handbook” and used it and tips from “Fast by Gast” to create one fast bike. John kept his 500 until he retired and moved to the coast in 2005. The whereabouts of Wild Jim, his 750 Kawasaki drag bike and the only copy of ‘Two Stoke Tuner’s Handbook” that I have ever seen is a complete mystery. I recently acquired a 1980 Polaris TXL and am digging into the inner

TOPICS FOR SPEAKING CYLINDER FRAME The cylinder section of the engine consists of a number of cylinder blocks, which are tightened together with the engine frame and the bedplate by means of through- going stay bolts. Two central bores, one at the top and one halfway down inside the cylinder block, enclose the cylinder liner. The upper part of the cylinder block forms part of the cooling water space around the central part of the cylinder liner, whereas the lower part forms the scavenge air space. A central bore in the bottom of the cylinder block encloses the piston rod stuffing box. The bottom is double with a hollow
which actuate the braking hardware and slow the vehicle. Air brakes use compressed air to maximise braking forces. Design and Function A compressed air brake system is divided into a supply system and a control system. The supply system compresses, stores and supplies high-pressure air to the control system as well as to additional air operated auxiliary truck systems (gearbox shift control, clutch pedal air assistance servo, etc.). How airbags work The design is conceptually simple; a central "Airbag control unit"[14] (ACU) (a specific type of ECU) monitors a number of related sensors within the vehicle, including accelerometers, impact sensors, side (door) pressure sensors[15], wheel speed sensors, gyroscopes, brake pressure sensors, and seat occupancy sensors. When the requisite 'threshold' has been reached or exceeded, the airbag control unit will trigger the ignition of a gas generator propellant to rapidly inflate a nylon fabric

..............................................................................................................13 Introduction What is nuclear power? Nuclear power is any nuclear technology designed to extract usable energy from atomic nuclei via controlled nuclear reactions. The most common method today is through nuclear fission, though other methods include nuclear fusion and radioactive decay. All utility-scale reactors heat water to produce steam, which is then converted into mechanical work for the purpose of generating electricity or propulsion. In 2007, 14% of the world's electricity came from nuclear power. More than 150 nuclear-powered naval vessels have been built, and a few radioisotope rockets have been produced. Nuclear life cycle The Nuclear Fuel Cycle begins when uranium is mined, enriched, and manufactured into nuclear fuel, which is delivered to a nuclear power plant. After usage in the power plant, the spent fuel is
Vocabulary with definitions Body and exterior Body components, including windows and trim: · Bonnet/hood : UK (US hood) the metal cover over the part of a car where the engine is I looked under the bonnet and clouds of smoke poured out. (KAPOTT) · Bonnet/hood latch: a type of mechanical fastener that is used to join two (or more) objects or surfaces together while allowing for the regular or eventual separation of the objects or surfaces. · Bumper: a horizontal bar along the lower front and lower back part of a motor vehicle to help protect it if there is an accident.
