Service Information Document Title: Function Group: Information Type: Date: Engine, description 200 Service Information 2014/9/11 Profile: EXC, FC2421C [GB] Engine, description D6E - tier 3 compliant The D6E configuration is a four stroke, straight six cylinder, turbocharged, direct injected diesel engine with charge air cooling and wet, replaceable cylinder liners. The D6E engine uses a Common Rail Fuel System controlled by the engine electronic control (E-ECU) software. Electronically controlled IEGR (Internal Exhaust Gas Recirculation) reduces NOѥ formation and lowers emissions without the need for exhaust after treatment. Volvo's latest engine management system, E-ECU is used to control all engine electronic functions. The cylinders are numbered consecutively beginning at the flywheel end. Engine rotational direction is counterclockwise as seen from the flywheel end. Figure 1 Engine, D6E Watermark,businessmanaccount:"thebestmanual",Pleasedonotresell.Thankyouverymuch.

Service Information Document Title: Function Group: Information Type: Date: Cylinder head, description 211 Service Information 2014/9/11 Profile: EXC, FC2421C [GB] Cylinder head, description The cylinder head is made of grey cast iron and is common for all cylinders. The induction air enters vertically (A) and the exhausts leave horizontally (B). Inlets and exhaust outlets are located on the same side of the cylinder block. Inlet and exhaust valve size is increased to optimize the gas exchange and combustion process. Valve guides are replaceable. Coolant flow in the cylinder head is modified to accommodate an outlet controlled cooling system. On order for the engine to fulfill governing emission standards, there are 3 cylinder head gaskets of different thicknesses between the cylinder head and the piston. Figure 1
