A sound mind in a sound body
Diagnostic inspection would be incomplete without the analysis of a dymnost of an exhaust of the car. 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 color which intensity amplifies by sharp pressing a gas pedal.
In frosty weather the serviceable car reserves quite dense clubs of white steam (not to confuse to a smoke!), fuels testifying to full combustion.
Long to inhale exhaust gases – is more expensive. We suppress the engine. But it yet ending. It is necessary to survey an internal surface of a stopper of a maslozalivny mouth. Existence of traces on it the made foam emulsion of lurid color – 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 antifreeze surfaces, 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 nose tip 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 "gray substance".
Oily ring corbel in width of 6-8 mm on an external surface of an exhaust pipe of the car ("a mourning rim") – a consequence of the raised consumption of oil. Major maintenance of the engine is inevitable.
Smoke of black color
Sign of incomplete combustion of fuel. The power supply system prepares very rich mix and needs adjustment.
Smoke of a gray (violet) shade
Sign of the raised consumption of oil. The engine demands replacement of maslosjemny caps or repair of tsilindro-piston group.
Dense white smoke
Sign of a burn-out of laying of a head of the block of cylinders of the engine. Cooling liquid gets to the combustion chamber.
Smoke with a smell of exhaust gases from the removed branch pipe of system of ventilation of a case (сапуна) the engine.
Sign of break of the fulfilled gases in an oil case because of the increased gaps in tsilindro-piston group.
