Description

What Is the Purpose of an Engine Block?

An engine block is an essential part of the structure of an internal combustion engine. It contains the crankcase and all its parts, including gaskets, valves and seals. The engine block contains cylindrically bored holes for the pistons and ways to attach other components such as the cylinder head. It is a solid, sturdy and heavy piece of equipment.

Engine Block

The purpose of the engine block is to support the components of the engine. Additionally, the engine block transfers heat from friction to the atmosphere and engine coolant. The material selected for the engine block is either gray cast iron or aluminum alloy. Both of these metals have good thermal conductivity and fluidity in the molten state.

Construction

The head is attached to the top surface of the cylinder block with studs/bolts. A gasket is used between the head and the block to provide a seal to prevent leakage of gases. Besides, the block also has ports, oil passages and water jackets carved inside it to provide lubrication and cooling. However, some cylinder blocks also house camshaft & have provisions to mount the related parts.

Moreover, the L-head engine blocks also contain openings for the valves & valve ports. The bottom of the block supports the crankshaft and also the oil pan. In most engines, the block also supports the camshaft through bushings that fit into machined holes. In some engines, the intake and exhaust manifolds are attached to the sides of the block. Other parts fitted to the block include the water pump, timing gear (both at the front) and flywheel, clutch housing (both at rear). They also include ignition, distributor, and fuel pump.

Cylinder block design

Furthermore, water-cooled engines have passages carved into the block. The circulating water maintains the engine optimum temperature and avoids excessive expansion and distortion of moving parts. Thus, it prevents the seizure of the relative moving parts.
