According to Fong fittings understand , so-called " burning oil " refers to the burning of oil in excess, its performance will be discharged when driving a blue tail exhaust . Mixed gas recovery experts said , under normal conditions , the engine will burn some of the oil tank mixed refrigerant burning oil is consumed these cylinders , pistons , piston rings friction and lubricates the crankcase oil importing oil combustion . Oil consumption is not only with the gap catheter valve and cylinder head machining and engine , the quality of the valve seal , cylinder honing , but also with oil type and the user running condition, mileage and other factors.
China's national standard GB3743-84 and GB / T 19055-2003 for oil / fuel consumption ratio has clear requirements , high oil consumption will lead to abnormal engine exhaust pollutants . Experts pointed out that mass-produced engines are allowed to meet national engine oil consumption and pollutant emission standards . Under normal circumstances, if the discharge is no problem, no problem engine oil consumption , consumers do not have to talk about " oil " pale , prone to suspect vehicle " burn oil ." By inspection of factory maintenance manual , the reporter found that the major manufacturers of oil consumption standards are not the same , the Audi 0.5 liter / 1000 km , the BMW 0.7 liter / 1000 km , Mercedes-Benz , Volkswagen, Honda, Toyota, 1 liter / 1000 km .
In addition, consumers pulled crankcase ventilation pipe joints see traces of oil , does not explain the failure of the engine 's oil and gas separation systems lead to " burn oil ." Experts explain this , since it is separated by mechanical principles to achieve , then completely absolutely not easy to achieve complete separation , intake manifold traces of oil in a small amount is normal . The experts further explained , with closed crankcase ventilation forced engine , its working principle is to conduct oil and gas mixture crankcase oil separator after entering the intake system through the pressure regulating valve , and then recovered during the intake stroke to import the combustion chamber. A small amount of fine particles can not be completely separated from the oil in the flow process , affected by temperature changes , condensation can occur on the wall of the ventilation and therefore the inner wall of the oil droplets will be accumulation phenomenon . Experts pointed out that if there is oil on the pipe with just judgment " burning oil " and even engine design flaw , it is too subjective and arbitrary.
Consumers should establish the correct engine oil consumption concept , do not be too sensitive , as long as the engine is running there will be oil consumption , normal oil consumption is a necessary condition to maintain the engine running , and will not cause harm to the engine . Under normal circumstances, abnormal oil consumption by changing the oil level on the dipstick within a certain mileage to make a simple judgment. Experts suggest that consumers should regularly check the oil dipstick , oil consumption is not normally found in a timely manner to the 4S shop for professional repair. |
