The engine belongs to 6-cylinder line units with the top arrangement of the camshaft (ohc), a cross and line head of cylinders from aluminum alloy and a pig-iron case.
The bent shaft is installed in seven radical bearings, central of which is persistent, being responsible for the size of an axial side play of a shaft.
Both radical, and conrod bearings have replaceable bimetallic inserts with an antifrictional layer on a steel tape.
Instead of separate covers of radical bearings one general is used with individual beds for each of bearings that gives to the block of cylinders additional rigidity.
Sealing of landing of a bent shaft is provided by forward and back epiploons, one of which is installed in the oil pump in a forward part of the block of cylinders, and the second - in the holder fixed on a back wall of the block. The camshaft is also equipped in front with the epiploon placed in a persistent plate of a shaft.
The drive of the camshaft is carried out by means of a gear gas-distributing belt from a cogwheel of a bent shaft. The tension of a belt is controlled by the special tension roller equipped with an adjusting spring and a blocking (lock) nut.
All valves are equipped with internal and external springs with the shortened step of the lower rounds. Turning of internal springs is made to the opposite side in relation to external. Besides, the direction of turning of sets of springs of final valves of the first, second and third cylinders is opposite to that for sets of other valves.
Hydraulic pushers have direct contact with cams of the camshaft and put cast yokes which, in turn, operate operation of valves in action.
Each hydraulic pusher, contrary to usual, is equipped with the device of automatic adjustment of valves, constantly maintaining zero value of a valvate gap.
The drive of the block of cylinders of the oil pump located in a forward part is carried out directly from a bent shaft.
The engine is hermetically connected to a flywheel casing for the purpose of extension of service life of a starter and coupling. The stopper for periodic discharge of accumulation of water and oil is provided in the lower part of a casing.
