CAV Fuel Injection: Description

CAV fuel injection system uses a mechanically governed distributor pump and CAV Pintaux injectors. Fuel is supplied to distributor pump by a conventional mechanical fuel pump at a pressure of 5-8 psi (.35-.56 kg/sq. cm). Distributor pump is preceded by two fuel filters. The first filter is used to remove most of the water and foreign matter from diesel fuel and second filter is a paper element type, which removes any remaining water or particles from fuel, before entering distributor pump. Distributor pump supplies fuel at a pressure of 1985 psi to individual injectors located in cylinder head. Glow plugs located in cylinder head are used for cold starts to aid in raising air/fuel temperature in combustion chambers. Glow plugs are controlled by a switch on instrument panel.
