Head of the block of cylinders

 


Arrangement of labels I and Е at installation of cogwheels

 

Рядный 4-cylinder, 4-taktnyj the petrol Engine of water cooling is equipped by two camshafts which are located in a head of cylinders. 16 valves (on 4 on each cylinder) are established V-shapedly. The drive of cam-shafts carries out ся from a cranked shaft a gear belt. One of two cam-shafts operates group of inlet valves, and other shaft – final valves. In a drive of valves there are hydraulic jacks of thermal backlashes.

The block of cylinders is cast from an aluminium alloy and unites four rowed cylinders. In расточках the block of cylinders pig-iron sleeves are established.

The cast head of the block of cylinders from an aluminium alloy is executed under the cross-section scheme of a purge of cylinders. Jacks of backlashes are established in a drive of each valve.

The shod steel cranked shaft leans against five radical bearings with вставны ми loose leaves. Shatunnye necks are located in one plane through 180 degrees.

The pig-iron camshaft is established on five bearings in the aluminium case which is located from above heads of cylinders. Rotation is transferred to a camshaft from a cranked shaft of the engine by means of a gear belt and a wheel established on the forward end of a cam-shaft.

The cogwheels established on both camshafts have одинако вую the form and are marked by letters I and Е (accordingly for a shaft operating inlet, and for a shaft, operating final valves).


The prevention

The new camshafts established on inlet and final valves, are interchangeable. However the shaft which were in operation, are not interchangeable.


Pistons are made of an aluminium alloy. On pistons it is established on two компрессионных and on one маслосъемному to a ring. For reduction of pressure of the piston by a wall of the cylinder during a working course of an axis of piston fingers have cross-section displacement of 0,35-1,65 mm concerning a piston axis.

In interface of a piston finger to the piston mobile landing, and with the top head of a rod – dense landing is used.

Movement is transferred to valves directly from camshaft cams. The hydrojacks established in pushers of valves, promote decrease in noise of the engine. The design of a drive of valves satisfies to hard work conditions at high frequency of rotation of the engine and allows to reduce labour input of maintenance service газораспределительного the mechanism.
