GENERAL INFORMATION

The block of cylinders is made of gray cast iron in which material engine cylinders are directly made. The head of the block of cylinders is made of an easy alloy and bolts fastens to the block of cylinders. In a head of the block of cylinders are pressed steel directing and saddles of valves. To the lower part of the block of cylinders of the engine the oil pallet in which the oil necessary for greasing and cooling of the engine flows down fastens.

On diesel engines for economy of a place inlet and final collectors are located on the one hand heads of the block of cylinders.

The camshaft is established in a head of the block of cylinders and is put in action by a gear belt from a pulley of a cranked shaft. Management of the inlet and final valves established vertically, is made by camshaft cams through hydraulic pushers. For supply of fuel in cylinders of the diesel engine the fuel pump of a high pressure fixed on the block of cylinders and put in action by a gear belt is used.

Adjustment of klapanny gaps is made automatically with use of hydraulic pushers, manual adjustment is not required.

For supply of oil to rubbing surfaces of the engine the oil pump is used. Under pressure oil moves to channels to bearings of cranked and distributive shaft.

The water pump fastens sideways the block of cylinders of the engine. Keep in mind that the system of cooling of the engine should be filled all the year round with an antifreeze and water mix with the low content of lime.

Fuel in the engine moves under pressure the fuel pump of a high pressure (TNVD) which fastens a flange sideways the block of cylinders and is put in action by a gear belt. On more powerful engines the turbonagnetatel using energy of exhaust gases is established.


Prevention

The fan of a radiator can turn on after engine and ignition switching off therefore at work on the hot engine be careful. In order that the fan of a radiator did not turn on, disconnect from the engine of the fan of a radiator the electric socket.
