Abstract

This paper describes the application of a spark plug sensor using a 3.392 μm infrared absorption technique to quantify the instantaneous gasoline concentration near the spark plug inside the engine cylinder. The mixture formation process near the spark plug in a port-injected spark-ignition (SI) engine was examined for different fuel injection timings, and determined that when the injection timing was delayed, a rich mixture remained near the top of the combustion chamber. Cyclic variations of fuel concentration at the spark timing were investigated.
