ABSTRACT
In the early decades of the 20th century, the numerical simulation takes place to improve the performance of the diesel engine whether it is two-stroke or four-stroke. Goodenough and Baker (1927), present a thermodynamic comparison between the Otto and diesel cycles for different compression ratios and air fuel different mixtures. The work, thermal efficiency and mean effective pressure (mep) are validated and give a good accuracy with an error varying from 2% to 3%. In (Assents et al., 1985), the numerical simulation using computers begin to take place and a group of researchers from Massachusetts Institute of Technology developed a computer simulation of a turbocharged diesel engine. The thermal loading models relate the heat flow through critical system components to material properties and design details and the simulation predicts the performance gains. Blair (1996), presents many details concerning the design of the two stroke engine; the engine geometry, scavenge air, compression ratio, air fuel ratio, gas emissions and noise levels. Simulation models are used to achieve the presented results. The exhaust temperature is assumed according to engine speed.
