Abstract

A system and method for facilitating cold starting of a direct injected, two-stroke engine. The engine utilizes a fuel injection system that is controlled to inject a fuel into a combustion chamber just before the piston reaches top dead center, at least during cold starting. This permits better atomization of a variety of fuels to promote dependable cold starting of the engine even when combusting a fuel type such as kerosene.
