Yangzhou Yangzhou diesel cars urea liquid urea solution in accordance with the provisions of wholesale, exhaust testing did not meet or hold environmental inspection marks and non-green car standard car will be banned in the city, with some sections. So how smoothly condition detected by the "big gate" to ensure their car emission standards, engine regular maintenance is the key. Column life for the majority of the current car owners usually are some simple tips for testing and maintenance, although maintenance could be entrusted 4S shop or auto repair shop arrangements, but you may say common sense, as the owner is required to have. A focus on prevention and control of motor vehicle pollution vehicle exhaust pollutants including carbon monoxide, hydrocarbons, nitrogen oxides, sulfur dioxide, soot particles and odor. In March this year, according to Municipal Environmental Protection Bureau statistics show that 85.9 percent of the city's carbon monoxide emissions from motor vehicles, and 34.7% and 16.5% of hydrocarbons and nitrogen oxides also comes from motor vehicles. Thus, motor vehicle exhaust is undoubtedly cities major source of pollution, especially high-emission vehicles. This year's "Twelfth Five-Year" period, will add two ammonia and nitrogen oxides emission reduction targets, vehicle exhaust control and governance will be the key and difficult future air pollution control. Causes excessive vehicle emissions due to road congestion and other reasons, it is easy to generate closed-loop EFI engine intake valve combustion chamber deposits, oxygen sensors, catalytic converters too much coke poisoning failures, clogged catalytic converters, ECR ( exhaust gas recirculation system) valve obstruction catching problems, causing the engine air-fuel ratio feedback control three-way catalyst system does not work properly, resulting in excessive emissions. If the owners can do the provisions of mileage oil change and maintenance, to avoid engine heat, no water tank, we found that abnormal timely treatment, can effectively avoid serious trouble. Since a few years ago was not relevant state departments of compulsory measures, the owners tend to ignore vehicle exhaust systems of care and maintenance. In our current vehicle, the mandatory retirement age provisions, the private vehicle if properly maintained, the engine life without overhaul, emissions can be reached. Former maintenance Caution To resolve excessive vehicle emissions, the engine of regular maintenance is the key. In terms of money or save other terms, usually more cost-effective maintenance, so do not miss the maintenance period. ● engine is the heart of the car, check the engine properly, you can remove the spark plug to see whether the oil was very clean and explain if normal ignition, the engine is not a string of oil, then increase the throttle to observe, whether the smooth and effective, if not more than check question that is normal. ● excessive exhaust is due to combustion chamber deposits, oxygen sensors, catalytic converters too much coke poisoning failures, as long as the activity of the catalytic converter is not lost, not completely blocked, for catalytic converters to clean, you can restore the three yuan catalyst activity, through the nozzle and the throttle cleaning and maintenance, in general: with the vehicle within 150,000 kilometers, after maintenance can be reached. ● mandatory exhaust testing is a vehicle containing more than six years, that in 2005 the purchase of vehicles, including some 2004 vehicles, catalytic converters yet fail blockage by cleaning and maintenance, you can restore the activity of catalytic converters But too much coke blocked, it can only replace the catalytic converter. Tips 6 Maintenance exhaust strokes 1. Timely use of additives. In case of emergency, you can use some additives, such as the "engine internal effects decarbonizer", by the process of "internal effects engine decarbonization agents", there can be one-time thorough cleaning of the intake manifold, intake and exhaust valves, combustion chamber, oxygen sensors, catalytic converters, from start to finish clear the "coke sludge dirt." It is worth noting that long-term use of the product will cause the vehicle dependent. 2. Change the oil regularly. Oil plays a major engine lubrication, cleaning, cooling, rust corrosion. Thus, each with 3,000 to 5,000 kilometers or every three months, can be considered for oil. 3. Regular exchange fuel cell. Each with 3,000 to 5,000 kilometers or every three months, regularly changing fuel cells, in addition, diesel fuel oil and water but also maintenance hair remover. 4. Regularly clean the carburetor and the air filter. Clean carburetor and air cleaner depends primarily cars with mileage, road conditions and the quality of gasoline may be recommended can travel 1,000 kilometers or every two weeks clean again. 5. Clean the burner support. Each driving 15,000 kilometers, raising the burner should be cleaned, while platinum burner may be extended, depending on the case, as the combustion. 6. Periodically check for leakage. When each driving 15,000 kilometers, check the crankcase ventilation, fuel system, whether there is leakage.
