3.1. Features of the device

Longitudinal and an engine cross-section

Engine mount

1 – a support casing;
2 – a support of a forward engine mount;
3 – a flange of the block of cylinders;
4 – an arm;
5 – an intermediate plate;
6 – an isolating plastic ring;
7 – a support spring;
8 – the buffer;
9 – a support pillow;
10 – a washer;
11 – a support of a back engine mount;
12 – the remote plug;
13 – a cross-beam of a back engine mount

On cars the 4-cylinder carburettor engine with рядным a vertical arrangement of cylinders and the top arrangement of a camshaft (fig. Longitudinal and an engine cross-section see) is established. Depending on model or car updating engines of three types can be established:

 – 2101 – with working volume 1,2 l. It is the engine of cars VAZ-2101;
 – 21011 – with working volume 1,3 l. The basic engine for cars VAZ-21011. 2101 it differs from engines in diameter of cylinders increased to 79 mm, therefore has others the block of cylinders, a lining of a head of cylinders and pistons with piston rings;
 – 2103 – with working volume 1,45 l. VAZ-21023 is applied on cars. From engines 2101 differs the piston stroke increased by 14 mm. Therefore has other cranked shaft and other details of a chain drive of the mechanism газораспределения. Besides, on it the carburettor with others тарировочными the data, intended for engines with working volume 1,45 l is established.

In the present section repair of the engine 2101 is described. Features of repair of engines 21011 and 2103 are stated in subsection and subsection 13.4.

The engine in gathering with coupling and a transmission is established on the car on three elastic support (fig. the Engine mount see). Support perceive both weight of the engine, and the loadings arising from vibration of the engine, from inertia of the engine at трогании the car from a place, dispersal and braking. Two forward support the engine fastens to a cross-beam of a forward suspension bracket of the car, and back – to a cross-beam of a back engine mount.
