Diesel engines

The cylinder block is made from cast iron, the material is made directly to the engine cylinders. Cylinder head in light alloy and is bolted to the cylinder block. The cylinder head pressed steel guides and valve seats. To the bottom of the cylinder block of the engine oil pan is attached to which drains oil needed to lubricate and cool the engine.

In diesel engines, to save space the intake and exhaust manifolds are located on one side of the cylinder head.

The camshaft is installed in the cylinder head and is driven by a toothed belt from the crankshaft pulley. Management of intake and exhaust valves mounted vertically, made cams camshaft via hydraulic tappets. For feeding fuel to the cylinders of the diesel engine using high pressure fuel pump mounted on the cylinder block and driven by a toothed belt.

Adjust the valve clearances is done automatically using hydraulic pushers, manual adjustment is required.

For the supply of oil to metal parts of the engine oil pump. Under the pressure of the oil supplied to the channels to the bearings of the crankshaft and camshaft.

The water pump is mounted on the side of the cylinder of the engine. Keep in mind that the engine cooling system must be filled all year round with a mixture of antifreeze and water with a low lime content.

Fuel is supplied to the engine under pressure from the high pressure fuel pump (pump), which is mounted on the side flange of the cylinder and is driven by a toothed belt. On a more powerful engine installed turbocharger using exhaust energy.

The radiator fan may turn on after turning off the engine and ignition, so when working on the engine is hot, be careful. To the radiator fan does not turn on, disconnect from the engine cooling fan electrical connector.
