a. The Diesel Engine Assembly, Model L70AE-DEGFR, NSN 2815-01-465-5993, hereafter referred to
as the engine, is a single cylinder, air cooled, direct injection, four-stroke cycle, diesel engine. The engine is
designed to operate between 3000 and 3600 RPM, with an output of 6.7 horsepower at 3600 RPM.
b. The engine has self-contained oil lubrication and fuel systems. It is equipped with an air filter and
housing (1, Figure 1-2), 24VDC starter motor (2), engine oil filter (4), oil fill cap and gauge (5), fuel injection
pump (8), and fuel injector (9). A recoil starter system (3) permits manual start of the engine without a battery.
All components are housed in or attached to an engine block (11).
c. A mechanical governor (6) mounted on the left side of the engine is set for 3750 RPM, maximum. In
generator set applications, an electrical actuator connected to the governor lever (7) controls the governor and
allows for variable speed operation.
