Abstract

The purpose of this study is to investigate the performance characteristics of the four~stroke diesel test engine that is available in the lab. The parameters measured from the test engine are speed, torque, power output, fuel consumption and exhaust gas temperature. The purpose of this study is also to develop a simulation model involving air flow in enwe performance. The exhaust temperature measured from the test engine will be used for simulation purpose. The simulation is carried out on the exhaust port of the cylinder head. The temperature deduced from simulation is compared with experimentally obtained results to from a correlation between experiment and simulation. Based on the measured parameters the optimum operating speed of the test engine is determined. The results obtained from this study indicates that there two speeds that gives the highest output power which are at 1800 rpm and 2600 rpm respectively. At this speeds the torque recorded is the highest and thus gives the highest power. The specific fuel consumption decreases with increasing power. Maintenance guidelines recommendation are proposed based on the experimental results.
