Experimental Simulation and Optimization of Performance of Four Stroke Spark Ignition Injector Engine

Abstract — An engine test experiment was carried out using engine test bed. The test was performed within a speed range of 1500 – 4500 rpm. The performance of an engine whose basic design parameters are known can be predicted with the assistance of simulation program into the less time, cost and near value of actual. The essence of this work is to develop a computer simulation programs for the analysis of engine performance parameters of four stroke spark ignition engine before embarking on full scale construction. They will ensure that only optimal parameters are in the design and development of an engine and also allow checking and developing the design of the engine and its operation alternatives in an inexpensive way and less time, instead of using experimental method which requires costly research test beds. The optimal values obtained for engine test experiment are; sfc is 0.2902kg/kwh, efficiency is 28.80 % and a/f is 16.50. For the designed window simulator, optimal values are; sfc is 0.2838kg/kwh, efficiency is 28.69 % and a/f is 15.53. From the results obtained, it could be seen that the simulator results show good agreement with experimental results, the models are therefore said to be verified
