Compression Test

If the engine works badly or with faults, check up system of ignition and fuel system. If the reasons for the poor performance of the engine could not be found, inspect a compression.

Regular carrying out of this check will allow you to advance and prevent the occurrence of faults.

PERFORMANCE ORDER

Check the engine oil level. Make sure the starter works normally, but the battery is fully charged. Start the engine and warm it to a temperature of 80-95 ?� C. Turn off the engine and remove the spark plug caps from the high-voltage wires. Remove the spark plugs. Rotate the crankshaft of the engine. Screw the tip compressometer in the spark plug hole. Fully open the throttle. Starter cranked shaft of the engine about 4 turns on the scale and determine the compression device. Compression: 1500 kpa minimum allowable compression: 1400 kpa. Repeat steps 6-8 on the remaining cylinders, making sure that the pressure drop for each cylinder is within acceptable limits. Permissible differential pressure in the cylinders of the engine: 100 kpa. If the compression is low in all the cylinders through the spark plug hole into the cylinders fill a few drops of engine oil and repeat steps 6-9. If oil filling compression raises perhaps worn piston rings. If the compression is at the same level may be burned or damaged valves cylinder head gasket. Replace the spark plug and connect them to the high-voltage wires. The tightening torque of the spark plugs: 20-30 N ??? m
