Abstract
A two cycle internal combustion engine with multiple cylinder fuel injection constantly secures an accurate air intake volume and as a result provides good power characteristics through appropriate control of the fuel injection. In order to accomplish this, the pressure inside the crank chamber is detected by a pressure sensor and the timing of the scavenging stroke and the engine speed are detected by determining the crank angle. An ECU then determines amount of air intake from the engine speed and the crank chamber pressure prior to commencement of the scavenging stroke, and the amount of fuel injected from an injector is based on the amount of this air intake.
