Abstract
A fuel injection control system of a two-cycle in-cylinder direct injection engine, wherein: in a low speed area, an injection of fuel is started immediately after a scavenging port of the engine has been closed, and all fuel is injected during the time when an exhaust port is opened to stabilize an idling operation of the engine; in a middle speed area, fuel is injected even for a period of time deviated from a period between a timing of closure of the scavenging port and a timing of closure of the exhaust port; and in a high speed area, a timing of start of the fuel injection is advanced with an increase of a rotational speed of the engine thereby to inject a required quantity of fuel.
