The multi-ignition method using a small amount of diesel spray was tested to control the burning rate of the gasoline mixture. Results of experiments and numerical analyses indicate that combustion duration can be controlled by the injection timing and the spatial distribution of the diesel oil. Fast combustion can be achieved by widely distributing the diesel oil in the cylinder, and this method suppresses knock and improves thermal efficiency.
