Claims2
The method of supplying air to an air-assisted fuel injection system for a combustion engine which includes the steps of supplying air from a principal air compressor to the fuel injection system during normal engine operation, driving a supplementary air compressor from an engine cranking motor while the cranking motor cranks the engine, and supplying air from the supplementary air compressor to the fuel injection system to facilitate prompt starting of the engine.
