subject: With Car Exhaust To Determine Fault [print this page] Motor vehicles or other equipment in the working process of the exhaust emissions. In modern civilization today, car has become an indispensable means of transport of human. Since 1886, the first since the birth of a car, it gives people's lives and work brought great convenience, but also has become one of the pillars of modern material civilization. However, we should see rapid development in the automotive industry, automobile production and ownership in the same time increasing car also brought air pollution, the automobile exhaust pollution.
Different cars have different tastes. We should note that the use of launch x431, this is a good vehicle fault detection tool, north of the contingencies. 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.
The first fault is that black smoke. Body Performance: Engine jitter big exhaust pipes are not normally given voice, while black smoke emission body, acceleration feel powerless. Failure: the phenomenon of black smoke emission vehicle more common in the carburetor, this is because the carburetor models computer-controlled fuel injection quantity not help, but by the foot throttle control, but some cases excessive too late after the burning of fuel into the cylinder on the exhaust on the car, thus causing the smoke we see.
Smoke more and fault arise, if the car is black smoke that causes carburetor is more complicated. Such as cold starts, bad spark plug work 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, before or after the mistake will cause smoke generated. EFI car black smoke of the little general, if it emitted a smoke, it is mostly cylinder body broke down. "Off tank" is a common one.
Approach: the basic carburetor cars now have on the age, should always check the carburetor and other parts of aging, carburetor cars is different from the EFI cars, to regular maintenance and adjustment, to develop good car habits. EFI car to check the tank every 30,000 km cable, check the spark plugs every 10,000 km, problems must be promptly replaced.
The second failure is that white smoke. Do not overlook several detection techniques, such as lexia3. Body performance: a car, we can see a lot of white water vapor emitted and not associated with engine running smoothly, even if the engine warm up a large number of normal working temperature is still emitting steam. Except in winter) Fault: cause to take the white smoke could be due to the engine cylinder cylinder pad wear, have a certain gap, resulting in a large number of water cooling system into the combustion chamber.
Approach: Check engine block, cylinder pad for any damage and check whether there is water inside the tank. View car specifications, strictly in accordance with the provisions of manufacturers to add the correct fuel grade. In addition, the low-temperature heat a small amount of white exhaust car will emerge, this is a normal exchange of hot and cold, warm up the car after the white smoke would disappear, this is normal.
The third is blue smoke. 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, often there are two situations: First, serious wear and tear. 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 burning, burning oil can not be discharged when the vehicle had a blue color of the smoke. Furthermore, oil filling too easily lead to burn oil. There are often a tool can be used to mb star. 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: on the older vehicles of age should always check the cylinder, piston and other parts of the seal, found that blue smoke emitted when the pits in time to repair, to prevent greater losses. Add oil to moderate, too much, too little undesirable. Regularly check the oil usage, once the abnormal oil consumption was found immediately to the professional repair station inspections.
We should always observe their own car, deal with the problem in time to grasp some of the processing tools such as launch x431,lexia3,mb star.This is very important.
