Abstract
A two-cycle engine has a scavenge pump provided in an intake passage, and a fuel injector provided for injecting fuel directly in a cylinder of the engine. A scavenge pressure sensor is provided in the intake passage for detecting a scavenge pressure. A plurality of data relative to quantity of air induced in the cylinder excluding escape air at scavenging the cylinder are stored in a memory. Quantity of air is derived from the memory in accordance with the detected scavenge pressure. Quantity of fuel injected by the fuel injector is calculated based on the derived quantity of air induced in the cylinder.
