Diesel Exhaust Failure To See The Color Check And Maintenance - Engine, Exhaust, Color
Caused by a bad injector working smoke emission phenomena in low-speed diesel engine running more apparent. 2, fuel oil in the mix.
3, piston ring counterparts, 4, in the body leading to very near the cylinder head gasket oil burning.
3, the combustion chamber shape change
Combustion chamber shape manufacturing quality does not meet the technical requirements, so that too much compression I sew too small and the piston position placed incorrectly will cause the combustion chamber shape change, thus affecting the mixture of fuel. finding electric problems in a car can be challenging. It is very difficult to trace one of the hundreds of wires in a vehicle. You need a specialized electric automotive repair shop to find most electric problems in a vehicleand air quality, combustion of fuel deterioration.
(B) blue smoke Oil into the cylinder, gas heating evaporation into the blue. Diesel engine at work, occasional row of black smoke, white smoke, blue smoke, which are not normal, it is to judge the conditions of diesel engine failure, as follows:
(A) smoke Diesel is a complex hydrocarbon, is injected into the combustion chamber unburned diesel fuel by pyrolysis to form carbon black. if you are handy you can probably replace the battery and or alternator in your reliable auto repair shop car. The problem is that the problem with your vehicle might not be caused by the battery or the alternator! It might be a short in a wire, a bad ground or just a sticky relay that causes the battery to drain or the alternator to not charge the battery. That is why there are professional auto repair shops! In addition, work overload, poor quality fuel, the exhaust temperature is too low can also cause black smoke.
5, piston rings, piston, cylinder liner wear
(C) of the white smoke Diesel engine or cooler when just starting state, the exhaust pipe to take the white smoke, because the temperature inside the cylinder diesel engine with low oil evaporation and formation. Indoor smoke from fuel combustion is incomplete combustion performance. Especially in winter. Because the low-speed running cylinder swirl is weak, oil drops or spray to reduce the possibility of by air currents to disperse and stay longer, more prone to form soot emissions.
5. The main reasons are:
1, piston rings, cylinder liner wear
Piston rings, cylinder liner wear, the compression pressure caused by inadequate, so that the end of the cylinder in the compression stroke, the normal ratio of mixing the mixture changes to fuel combustion in the absence of oxygen, resulting in carbon deposition.
Complete combustion of diesel engine fuel, the normal exhaust color is generally light gray, dark gray when the load a little weight. Excessive oil Excessive oil to enter the cylinder of oil increased, resulting in less oil more than gas fuel incomplete combustion. The main factors are as follows:
1, air filter blocking, poor intake or oil basin oil level is too high (oil bath air filter).

4, fuel supply advance angle adjustment inappropriate
1) fuel supply advance angle is too large, the fuel sprayed into the combustion chamber early, because this time the lower cylinder pressure and temperature, fuel can not be ignited when the piston upward, the cylinder pressure and certain temperature, the combustible mixture combustion.
1, cylinder head gasket has cracks or damage, the cooling water into the cylinder, formed when the water mist or water vapor exhaust.. If the heat engine, the exhaust pipe is still white fume were judged as engine failure. Exhaust emissions when accompanied with the formation of exhaust smoke. Exhaust emissions, together with the blue smoke, mainly due to:
2) fuel supply advance angle is too small, the fuel sprayed into the cylinder late, too late to form part of the combustible fuel mixture to be separated or discharged, as exhaust emission fuel by pyrolysis, the formation of black smoke.
2, bad injector work Injector does not spray or drip, so that fuel can not be fully mixed with the air within the cylinder can not fully burn
3, piston ring counterparts, 4, in the body leading to very near the cylinder head gasket oil burning.
