3.1.1. Introduction
THE GENERAL DATA

The engine with four cylinders, established cross-section in a forward part of the car. Coupling and a transmission are located on the left side of the engine.

The block of cylinders is made of an aluminium alloy. The cranked shaft leans against 5 main bearings. Persistent half rings are established on the third radical bearing.

In the bottom heads of a rod loose leaves are established. Pistons fasten to rods piston fingers. Pistons from an aluminium alloy also have three piston rings, two sealing and one маслосъемное.

The camshaft located in the top part of a head of the block of cylinders, puts in action a gear belt of a drive and operates valves through the hydraulic pushers located under cams of a camshaft.

Engine greasing is made under the pressure created by the oil pump. Oil is sucked in through the mesh filter located in маслоприемнике and then arrives through the external established filter in channels of the block of the cylinder. Therefrom oil arrives to a cranked shaft and a camshaft. Bearings of the bottom head of a rod are supplied with oil through internal drilling in a cranked shaft. To bearings of a camshaft oil also moves under pressure. Camshaft and valve cams are greased with the sprayed oil, also as well as all other mobile details of the engine.
