2.7.11. Check of tightness of system of production of the fulfilled gasesOn cars with adjustable catalytic converter in front of the sensor of concentration of oxygen (lambda probe) can lead a leakage of connections of system of release to the following malfunctions:
– difficulties at engine start-up;
– engine глохнет;
– non-uniform operation of the engine idling;
– breakthroughs at acceleration.
Check condition
The engine cold or has hand temperature.
The source of the compressed air is necessary for check.
Start the engine and hear on the working engine to system of production of the fulfilled gases on existence of not tight places.
Muffle the engine.
Insert the gun of a source of the compressed air (compressor) into an exhaust pipe and condense with a rag.
Establish pressure of the compressed air equal the 6th bar. Turn on the gun.
Cover junctions of a head of the block of cylinders and a final collector, a final collector and a reception pipe of the exhaust silencer, a reception pipe of the exhaust silencer and catalytic converter with means for search of places of leaks and check on formation of vials.
Eliminate a leakage of system of release.
