(30) Inlet air temperature sensor Note: The primary fuel filter (25) may be supplied loose.Note: The Electronic Control Module (ECM) (27) will be mounted to the application.The C3.4B diesel engine is electronically controlled. The C3.4B engine has an Electronic Control Module (ECM) that receives signals from the fuel injection pump and other sensors in order 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 two inlet valves and two exhaust valves for each cylinder. The port for the exhaust valves is on the right side of the cylinder head. The port for the inlet valves 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 in order to cool the piston. The pistons have a Quiescent combustion chamber in the top of the piston in order to achieve clean exhaust emissions. The piston pin is off-center in order 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 in order to reduce wear of the groove. The skirt has a layer of graphite in order to reduce the risk of seizure when the engine is new. The correct piston height is important in order 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 in order to conform to requirements for emissions.The crankshaft has five main bearing journals. End play is controlled by thrust washers which are located on both sides of the number 3 main bearing.The timing case is made of cast iron. Some of the timing gears are stamped with timing marks in order to ensure the correct assembly of the gears. When the number 1 piston is at a certain position, the marked teeth on the camshaft gear will align with the marks that are on the gear on the crankshaft.There are no timing marks on the rear face of the timing case.The crankshaft gear turns the camshaft gear which then turns the following gears:
the idler gear
the idler gear for the engine oil pump
the engine oil pump gear
the accessory drive gear
the fuel injection pump gearThe camshaft runs at half the rpm of the crankshaft. The fuel injection pump runs at one and a half times the speed as the crankshaft.The fuel injection pump that is installed on the left side of the engine is gear-driven from the timing case. The internal fuel transfer pump is driven by the fuel injection pump. The fuel transfer pump draws low pressure fuel from the primary fuel filter. The fuel transfer pump delivers the fuel to the secondary filter. The fuel then travels to the fuel injection pump.The fuel injection pump increases the fuel to a maximum pressure of 180 MPa (26107 psi). The fuel injection pump delivers the fuel to the fuel manifold (Rail). The fuel injection pump is not serviceable. The engine uses speed sensors and the Electronic Control Module (ECM) to control the engine speed.For the specifications of the C3.4B engine, refer to the Specifications, "Engine Design".
