| The internal combustion engine is powered by the burning of a precise mixture of liquid fuel and air in teh combustion chambers of the cylinders. Fuel is stored in a tank until it is needed, then it is pumped into a carburetor or, to a fuel injection system. The carburetor controls the mixture of gas and air that travels into the engine. It mixes fuel with air at the head of a pipe, called the intake manifold, which leads to the cylinders. A vacuum created by the downward strokes of pistons draws air through the carburetor and intake manifold. Inside the carburetor, the airflow transforms drops of fuel into a fine mist or vapor. The intake manifold delivers the fuel vapor to the cylinders, where it is then ignited. All cars made today are equipped with a fuel injection system instead of a carburetor. Fuel injectors spray carefully calibrated bursts of fuel mist into cylinders either at or near openings to the combustion chambers. Since the exact quantity that is needed is injected to the cylinders, fuel injection is more precise, easier to adjust, and more consistent than a carburetor, delivering better efficiency, gas mileage, engine responsiveness, and pollution control. Most are operated electronically. High performanace cars are often times fitted with air compressing equipment that increases an engine's output. By increasing the air and fuel flow to the engine, these features produce greater horsepower. Superchargers are compressors powered by the crankshaft. Turbochargers are turbine-powered compressors run by pressurized exhaust gas. |
