Abstract:
1. A charge-injected internal combustion engine, comprising: a base engine comprising a crankshaft; an air-fuel injection valve operatively attached to the base engine for injecting an air-fuel charge into a combustion chamber thereof; an air pump driven by the crankshaft for discharging compressed air for use as combustion air; an injection timing controller for setting injection timing of the air-fuel injection valve, and an engine state sensor for detecting a state of the internal combustion engine, wherein the controller normally sets the injection timing to the compression stroke of the internal combustion engine according to the engine state detected by the engine state sensor, and when an initial starting condition of the internal combustion engine is detected by the engine state sensor, the injection timing is temporarily switched to the intake stroke of the internal combustion engine.
