Analytical Studying of the Effect of Different Ignition Systems on the Engine Performance

Abstract

Laser ignition is considered to be one of the most promising future ignition concepts for internal combustion engines. This study focuses on the investigation of the different ignition systems which affect engine performance. Conventional (CIS), electronic (EIS) and laser ignition systems (LIS) were used during this studying. The major engine performances were predicted such as power, torque, and specific fuel consumption, in addition to cylinder temperature and pressure. The output of the engine performance using computational model was established in MATLAB/Simulink. The results show that, the Laser ignition system (LIS) causes improves of the internal combustion engine performance. Where the results showed increases the power by about 15%, torque is increasing up to 16%, improves the BSFC by about 18 %, while the cylinder pressure is increased to 11% and LIS gives higher combustion temperatures when compared to other systems.
