摘要:
Modeling of a compression ignition engine was carried out covering losses emanent from imperfect construction of real engines such as progressive combustion, valve timing, and heat transfer. Furthermore, friction was included to obtain brake performance. Simulation of engine performance was tackled by varying engine speed, compression ratio and injection timing over wide range. The results were compared with those obtained from the experiemntal facility. Predictions by the model compare favourably with experiment within 9·3% and 9·7% for power and sfc respectively. The losses considered in this work amount to about 30% of the fuel energy input at the design point.
