Perkins 854E-E34TA, 854F-E34T & 854F-E34TA Engine Systems Operation Testing & Adjusting Manual
PREFACE:
The 854E-E34TA, 854F-E34T, and 854F-E34TA diesel engines are electronically controlled. The 854E-E34TA, 854F-E34T, and 854F-E34TA engines have an Electronic Control Module (ECM) that receives signals from the fuel injection pump and other sensors to control the electronic unit injector. The fuel injection pump supplies fuel to the fuel manifold (Rail). The fuel manifold (Rail) distributes fuel to the electronic unit injectors. The four cylinders are arranged in-line.
- The cylinder head assembly has one inlet valve and one exhaust valve for each cylinder. The port for the exhaust valve is on the right side of the cylinder head. The port for the inlet valve is on the top of the cylinder head.
- Each cylinder valve has a single valve spring. Each cylinder has a piston cooling jet that is installed in the cylinder block. The piston cooling jet sprays engine oil onto the inner surface of the piston to cool the piston.
- The pistons have a Quiescent combustion chamber in the top of the piston to achieve clean exhaust emissions. The piston pin is off-center to reduce the noise level. The pistons have two compression rings and an oil control ring.
- The groove for the top ring has a hard metal insert to reduce wear of the groove. The skirt has a layer of graphite to reduce the risk of seizure when the engine is new. The correct piston height is important to ensure that the piston does not contact the cylinder head. The correct piston height also ensures the efficient combustion of fuel which is necessary to conform to requirements for emissions.
