It is a six cylinder, four stroke cycle valve-in-head engine having a displacement of 504 cubic inches. Equip- ment mounted on the engine include the alternator f u e l i n j e c t i o n p u m p , a n d f u e l f i l t e r s. , air compressor, starting motor, 1-18. FUEL SYSTEM 1. FUEL INJECTOR NOZZLES. Six used; one in each cylinder located in cylinder head. Directs a metered quantity of fuel received from injection pump to combustion chamber. Each charge of fuel must be delivered into the combustion chamber with a, definite spray pattern to ensure complete combustion and efficient engine performance. 2. FUEL INJECTION PUMP AND LINES. Fuel injection pump delivers accurately metered quantities of fuel under high pressure to fuel injectors. This delivery must be ac- complished with accurate timing in relation to engine firing order and for a defi- nite period of time in relation to load and engine speed requirements. Fuel is routed to six fuel injectors from fuel injection pump through rigid metal tubes. Return fuel (leak-off) from fuel injectors is routed through rigid metal tubes connected between each fuel injector and then routed through one rigid metal tube back to fuel injection pump. 1-15
