3.3.22. Analysis of smoke of an exhaust

GENERAL INFORMATION

A sound mind in a sound body

Diagnostic inspection would be incomplete without analysis of smoke of an exhaust of the car. It is already rather heated-up so it is a high time to approach 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 white color which intensity amplifies by sharp pressing the accelerator pedal.

In frosty weather the serviceable car reserves quite dense clouds of white steam (not to confuse to smoke!), the fuels demonstrating full combustion.

To long inhale exhaust gases – is more expensive to itself. We suppress the engine. But it is not the final yet. It is worth surveying 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 antifreeze oil. Having uncovered a broad tank or a radiator, survey antifreeze. Attention: to avoid a trauma, it is necessary to do it on the cooled-down engine! An oil film on the surfaces of antifreeze, the same as the made foam engine oil – harbingers of urgent repair of the engine.

Here, perhaps, and all. We completely examined "patient", having passed literally from a nose tip to a tail. Also used at survey the equipment not expensive, inaccessible to most of motorists, and what is given us by nature: sight, hearing, sense of smell and, of course, mysterious "gray substance".

Oily ring corbel 6-8 mm wide on an external surface of an exhaust pipe of the car ("a mourning rim") – the investigation of the raised oil consumption. Capital repairs of the engine are 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 oil consumption. The engine demands replacement of oil scraper 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 (sapun) of the engine.

Sign of break of the fulfilled gases in an oil case because of the increased gaps in tsilindro-piston group.
