Cylinder-and-Crankcase Block

Diesel engines are provided each with cast iron cylinder-and-crankcase block 1 which serves to accommodate all the components and units of the engine. Press-fitted into block 1 are cylinder liners 17. The outside surface of the liners is washed by the coolant, and the water jacket is sealed off by shoulders at the top and by rubber rings 20 at the bottom; the shoulders are lapped to the block. Arranged at the front end of the block are timing gears protected by cover plate 37.

Topping the block is cast iron cylinder head 12, two cylinders sharing one cylinder head. The joint between the cylinder head and block is sealed off by asbestos steel gasket 10.
