Some Analytical Investigations on a Four Stroke Diesel Engine for High Specific Output and Low Heat Rejection 900618
In the past, a number of reported developments have indicated the problems of high specific output engines and the special measures to combat these problems, namely Atkinson cycle, low and variable compression ratio, manoeuvring timing and rate of injection, multiple introduction of fuel etc. Recent studies have shown that low heat rejection and turbocompounding could be applied to existing engine series to improve fuel economy. As experimental evaluation of the effectiveness of above measures for a single system is a complex and costly task, this paper reports a systematic analytical investigation using diesel cycle simulation in which the potential of each measure in terms of specific output and fuel economy has been assessed and compared with other alternatives when a diesel engine is uprated from naturally aspirated mode.
