ABSTRACT:
A positive displacement fuel injection system for use with a combustion engine including a fuel pump (10,10') which forms and delivers pre-metered slugs of fuel and timing fluid to unit injectors (300,300') associated with the engine combustion chambers. The pre-metered slug of timing fluid has a prescribed volume and sets the timing advance for the unit injector. The fuel pump can vary the size of the pre-metered slugs of fuel and timing fluid on a cycle-by-cycle basis.
