Abstract

This paper searched through mixture ratio response test whether exert effect that is some in part load performance of engine according to inlet valve angle in gasoline engine. Engines that inlet valve angle is narrow decreased quantity of NOx among exhaust gas than engine that inlet valve angle is wide, and ignition timing was retard, and fuel consumption improved a little. That quantity of NOx among exhaust gas decreases and ignition timing was retard can judge that fast burning occurred. Fast burning can decrease output decline and misfire that can happen at lean burning. Can be judged by thing which engine's combustion performance improves if inlet valve angle is narrow if examine test result.
