Document Summary

Combustion engine: an engine which generates mechanical power by combustion of a fuel. Piston seals the cylinder and transmits the combustion generated gas pressure to the crank pin via connecting rod. Carburetor controls fuel flow for the air flow. Mbt spark timing which gives maximum torque. Cylinder engine types single, in line, opposed, radial and v type. Turbocharged air is compressed by exhaust driven turbine-compressor. Supercharger air is compressed mechanically driven pump: crankcase compressed. Fuel input: carbureted, multipoint port injection, throttle body fuel injection. Valve location: valves in head (overhead or i head, valves in block (flathead or l head, one in head, one in block (f head): Indirect and direct fuel injection systems by nick. The main difference between direct and indirect injection is the layout of the injection system, the indirect. The advantages of an indirect injection" system compared to direct injection" are: High rate of swirl over wide range of engine speeds.
