subject: Know Your Car With Smoke Smell Car Exhaust Determine Fault - Exhaust - Automotive Repair And [print this page] All know, "Scent of a Woman," here is that smell tobacco awareness Car . Different cars have different tastes. Automotive experts suggest that the normal exhaust should be colorless, no smell, and taste of different colors in different automobile exhaust is likely that the vehicle itself is facing some trouble.

Normal exhaust gas: a colorless, odorless, and expel the exhaust pipe when a small amount of water discharged, then all the normal vehicle operation.
Smoke Body Performance: Engine Shake Large, the exhaust pipe has not issued a normal voice, while black smoke emission body, acceleration feel powerless.
Cause of the malfunction: the phenomenon of black smoke emission vehicle more common in carburetor, carburetor models this is because computer-controlled fuel injection quantity not help, but by the foot Accelerator Control, and some cases too much too late after the burning of fuel into the cylinder on the exhaust on the car, thus causing the smoke we see. Failure
produce smoke more, if the car is black smoke that causes carburetor is more complicated. Such as Cold start When the work of bad spark plug Necessary to Play in half a day to start the motor, so product mix in the cylinder can not be completely burned natural gas will have a smoke discharge; or a vehicle fire at the wrong time, early or wrong can lead to smoke after generated.
EFI cars generally very little black smoke, the smoke emitted, if true, it probably is the cylinder body broke down. "Off tank" is a common one.
Approach: 1. Carburetor basically have the car now was old, and should always check the carburetor and other parts of aging, carburetor cars is different from the EFI cars, to regular maintenance and calibration, develop a good car habits.
2. EFI car to check the tank every 30,000 km cable, check the spark plugs every 10,000 km, problems must be promptly replaced.
White smoke Body performance: a car, we can see a lot of white steam emitting from the engine running is not accompanied by a smooth, even if the engine warm up a large number of normal working temperature is still emitting steam. (Winter excluded)
Fault: cause to take the white smoke could be due to the engine cylinder cylinder pad Wear and tear , Have a certain gap, resulting in a large number of water cooling system into the combustion chamber. Water is not burning, heat strainer? Injury? Ram?? Benzene yo You card? Pyrene cowardly Gong? BR> approach:
1. Check the engine cylinder block, cylinder pad for any damage and check whether there is water inside the tank.
2. View car manual, the provisions strictly in accordance with manufacturers to add the correct grade of gasoline.
Note: The low temperature Hot car When a small amount of white exhaust will emerge, this is a normal exchange of hot and cold, warm up the car after the white smoke would disappear, this is normal.
Lanyan Body performance: vehicle explosive down, feeling weak acceleration, noise becomes larger, blue exhaust smoke emission, and is accompanied by oil produced by combustion of coke burnt taste. At the same time by checking the oil gauge will be found excessive oil consumption, maintenance under normal circumstances, each finished running for 7500 km, the oil consumption should be within the normal range, no way to add.
Fault: blue smoke more because of internal engine failure, causing oil fleeing into the combustion chamber product of combustion, there are two common situations:
First serious wear. Scratch the inner walls of the cylinder, piston seal wear bad or severe valve Department, will have a gap, and the original charge of lubricating oil at this time will participate in the combustion chamber through the gap fleeing into combustion, combustion of oil not discharged when the vehicle had a blue color of the smoke.
Also easily lead to excessive oil filling Burning oil . Some owners mistakenly believe that the better the oil increases, but does not know too much oil will be brought into the cylinder for combustion, resulting in the phenomenon of burning oil; the same time, excess oil will block the normal operation of the crank arm, allowed to do work the additional increased energy consumption.
Approach: 1. On the vehicle age older vehicles should always check the cylinder, piston and other parts of the seal, discovered in time to when the blue smoke emissions Service Station repairs to prevent further losses.
2. Add oil to moderate, too much, too little undesirable.
3. Regularly check the oil usage, once the abnormal oil consumption was found immediately to the professional repair station inspections.
