2.13.4. Compression check
THE GENERAL DATA

The compression and difference of its values on cylinders shows degree of deterioration of the engine. Measurement of a compression is better for spending at servicing deport.

Definition of degree of deterioration of the engine on a compression


The engine
Compression, МПа
The new engine
Deterioration limit
Maximum permissible difference of values in cylinders
Petrol 1,0 l, 37 kw and 1,4 l, 50 kw
Not more low 1,2
0,75
No more than 0,3
Diesel 1,9 l, 74 kw
2,5 – 3,1

No more than 0,5

PERFORMANCE ORDER
1. Remove the top casing of the engine (subsection 2.1 see).
2. At petrol engines of 1,0 l, 37 kw and 1,4 l, 50 kw disconnect колодку 1 with wires from the module of 2 ignitions, turn out spark plugs (subsection 10.3.3 see) and take out a safety lock №35 of the block of safety locks.
3. At the diesel engine of 1,9 l, 74 kw disconnect колодку a plait of wires of pumps-atomizers from a plait of wires, turn out candles накаливания and instead of candles screw a special adapter.
4. Connect the device for compression measurement.
5. Scroll the engine a starter until on a device scale pressure is not stabilised. Thus at the petrol engine it is necessary to press an accelerator pedal against the stop.
6. Similarly check up a compression in other cylinders.
7. Disconnect the device for measurement of a compression and establish all removed details.
8. Clear memory of malfunctions of the block of engine management.
