904D-E36TA Engine
The Perkins 904D-E36TA industrial engine is a single
turbocharged, air to air charge cooled engine with an
engine prefix of FT.
The configuration will depend on the power output of
the engine.
Note:
The front end of the engine is opposite the
flywheel end of the engine. The left and the right
sides of the engine are determined from the flywheel
end. The number 1 cylinder is the front cylinder.

Electronic Engine Features
The engine operating conditions are monitored. The
Electronic Control Module (ECM) controls the
response of the engine to these conditions and to the
demands of the operator. These conditions and
operator demands determine the precise control of
fuel injection by the ECM. The electronic engine
control system provides the following features:
• Engine monitoring
• Engine speed governing
• Control of the injection pressure
• Cold start strategy
• Automatic air/fuel ratio control
