Abstract
An oil activated fuel injector which provides a pilot quantity of fuel prior to the main fuel injection event. The oil activated fuel injector includes a delay piston assembly in fluid communication with a high pressure chamber of the fuel injector. The pilot quantity of fuel flows through the delay piston during a pre stroke of the plunger. The oil activated fuel injector reduces engine emissions and noise, and eliminates the need for additional working fluid to be provided therein in order to provide a pilot quantity of fuel.
