SOME SPECIAL FEATURES OF THE TURBOCHARGED GASOLINE ENGINE
Some special features of the turbocharged gasoline engine are discussed in comparison with the turbocharged Diesel engine. The influence of compression-ratio, temperature of the charge air, air/fuel-ratio and ignition-timing on combustion, fuel economy and power output is shown. A combined compressor- and engine air-flow-map of the turbo-charged gasoline-engine is developed and the features of a compressor matching the special requirements of a TC gasoline engine are deduced from this map. The position of the throttle in the intake-system, which has great influence on governing-qualities and load-change-responce of a turbocharged gasoline engine is discussed and the problems and disadvantages of a waste-gate governed turbocharger especially in connection with a gasoline engine are figured out.
