Check компрессионного pressure in engine cylinders

Are issued компрессометры two types: with nozzles of clamping and carving type. The last are rolled in candle apertures and provide more reliable measurement though their connection and is connected with a little big time expenses.


 PERFORMANCE ORDER

1. Decrease in efficiency of return of the engine, the excessive expense of oil and-or fuel should be considered as signs of excessive deterioration of internal components of the power unit. Measurement компрессионного pressure in each of engine cylinders will allow to localise a problem.
2. Check up level impellent oil and completeness of a charge of the storage battery.
3. Warm up the engine to normal working temperature, then muffle it.
4. Disconnect ignition system.
5. Mark and disconnect ВВ wires from spark plugs.
6. Carefully blow candle niches (it is possible to take advantage of the usual bicycle pump), then turn out spark plugs.
7. Translate throttle заслонку in completely open position, - block a drive заслонки, or ask to keep the assistant a gas pedal completely squeezed out.
8. Densely screw a transitive nozzle компрессометра in a candle aperture of the first cylinder of the engine.

Try not to strip a thread in a head!

9. Operating according to instructions of manufacturers of the device, connect the remote switch to a starter chain.
10. Make sure, that the ignition key will turn in position OFF and by means of the remote switch turn the engine not less than on five turns of a cranked shaft (проворачивание should last not less than 5 seconds). Consider and write down the indication компрессометра.
11. Operating in a similar manner, serially measure компрессионное pressure in the remained cylinders of the engine.
12. Compare among themselves results of measurements, - they should not differ more than on 25 %. So, if the maximum indication makes 1034 кПа, minimum should make not less than 75 % from the given figure, i.e. to be not more low 779 кПа.
13. At excessively low pressure in any of cylinders it is necessary to fill in in it through a candle aperture approximately a teaspoon of impellent oil and to repeat check. If oil addition leads to situation correction excessive deterioration of piston rings and-or mirrors of cylinders, hence, takes place. Otherwise it is possible to speak with enough high degree of probability about a burn-out / mechanical damage of working facets of valves or their saddles (the probability of infringement of integrity of a lining of a head of cylinders is not excluded also). The reason of identical pressure decrease in two next cylinders usually is breakdown of a crosspiece of a sealing lining between the given cylinders (oil addition will not lead to situation correction). Hit in chambers of combustion of oil and cooling liquid (it is usually accompanied by occurrence of a dense white or dark blue smoke on an exhaust, - it is not necessary to confuse to the white smoke formed during warming up of the engine or at operation of the car in cold weather) it is possible to regard as one more acknowledgement of the fact of infringement of integrity of a lining, - check up impellent oil on presence of signs of presence at it of a cooling liquid.
