1. General Description

The in-line four-cylinder overhead cam engine is water-cooled and transmits power through a piston-driven crankshaft. The cylinder block is made of cast iron with integral cylinders completely exposed on all sides to the coolant that circulates through the water jacket. A separate cast aluminum alloy cylinder head contains the belt-driven camshaft and the entire valve train. On diesel engines, the camshaft drive belt also drives the fuel injection pump. A cutaway view of the engine appears in Fig. 1-1.
