Diagnostic inspection would be incomplete without the analysis дымности a car exhaust. It is already enough heated-up, so it is a high time to approach to its "loin" and to glance to a horse "under a tail".
The exhaust of the serviceable engine is almost colourless. The exhaust pipe leaves hardly distinguishable easy smoke of the white colour which intensity amplifies by sharp pressing a gas pedal.
In frosty weather the serviceable car reserves dense enough clubs of white steam (not to confuse to a smoke!), testifying to full combustion of fuel.
Long to inhale exhaust gases – is more expensive. We suppress the engine. But it yet the ending. It is necessary to survey an internal surface of a stopper маслозаливной mouths. Presence on it of traces made foam эмульсии lurid colour – very disturbing symptom speaking about infiltration in oil of antifreeze. Having uncovered a broad tank or a radiator, survey antifreeze. Attention: to avoid a trauma, to do it it is necessary on the cooled down engine! An oil film on an antifreeze surface, the same as the made foam engine oil – harbingers of urgent repair of the engine.
Here, perhaps, and all. We completely surveyed "patient", having walked literally from a tip of a nose to a tail. Also used at survey not expensive, inaccessible to the majority of motorists the equipment, and that is given us by nature: sight, hearing, sense of smell and, certainly, mysterious "grey substance".
Oily ring corbel in width of 6-8 mm on an external surface of an exhaust pipe of the car ("mourning ободок") – a consequence of the raised expense of oil. Engine major repairs are inevitable.
Smoke of black colour
Sign of incomplete combustion of fuel. The power supply system prepares very rich mix and requires adjustment.
Smoke of a grey (violet) shade
Sign of the raised expense of oil. The engine demands replacement маслосъемных caps or repair of tsilindro-piston group.
Dense white smoke
Sign of a burn-out of a lining of a head of the block of cylinders of the engine. The cooling liquid gets to the combustion chamber.
Smoke with a smell of exhaust gases from the removed branch pipe of system of ventilation картера (сапуна) the engine.
Sign of break of the fulfilled gases in oil картер because of the increased backlashes in tsilindro-piston group.
