Study of Gasoline Direct Injection Engine Optimum Ignition Advanced Angle Control Algorithm

In order to improve the dynamic property and economical efficieny of gasoline direct injection engine, an experiment was conducted to study the impact the ignition advanced angle had on engine performance. According to actual operation of the engine, the influence of eternal factors on the best ignition advanced angle of gasoline direct injection engine was studied through the combination of theoretical analysis and experiments, after whien the corresponding compensation of various factors for the best igniton advanced angle was proposed. A control algorithm for the best ignition advanced angle fo gasoline direct injection engine was proposed based on the current use of the control over the best advanced angle of gasoline engines, whien turned out to be a simpler, more accurate and moer efficient method to realize the control over the best ignition advanced angle.
