Throughout time operation of the vehicle, there are situations when there are changes in color of smoke from the exhaust pipe: until recently, he was white, now - black, but tomorrow it may be quite different shades. What does this mean and how to display the general condition of your car?
The appearance of smoke caused by the violation of some parts of the engine as a result of failures of power, ignition systems, cooling systems, fuel injection control system and other mechanisms. Improper combustion of fuel or oil supply to the cylinder gives the characteristic color of the exhaust gases.
Of course, the appearance of black smoke will not harm the appearance of the vehicle and car painting is not required, but the technical condition of vehicles will be disrupted due to failures in certain parts.
Experience has shown that disruption of a system malfunction triggers the other, and a vicious circle. For example, engine overheating occurs due to poor performance of the cooling system and piston ring sticking is inevitable. As a result, the surface of the cylinder gets oil, and smoke is not a myth but a reality.
Warming up a cold engine is accompanied by the appearance of white smoke from the exhaust pipe. If the cooling system is characterized by high humidity, the condensation turns to steam and heated exhaust system converts the moisture in the visible liquid. Engine warming accompanied by the formation of drops at the end of the exhaust pipe, which suggests the presence of water in the system.
Only a series of tests can confirm the problem of the formation of white smoke due to hit the coolant into the cylinders. Formed a cloud quickly dissipates and leaves in the air hazy education. To make 100% sure of the exhaust pipe enters the water, not oil, it is necessary to close the orifice exhaust pipe sheet of paper on the warmed up engine. Drops of H2O will evaporate quickly and not leave any greasy residue.
Diagnostics Education malignant smoke "carry out service centers, providing a full spectrum of operations. In addition to engine overhaul, replacement tires and windshield, a priority activity is the repair of bumpers and a study on the carburetor troubleshooting. All work must be carried out in accordance with international requirements for compliance with safety regulations.
