In the routine maintenance of vehicles, the air filter and PCV valve pressure easily be ignored. Moreover, often when they plug into the engine and endanger the normal working hours will be subject to remedy the situation as the replacement of the maintenance. In order to avoid premature engine wear (non-normal) and maintain the best working condition, the pressure of the air filter and PCV valve for regular inspection and replacement is all the more essential.
We emphasize on preventive maintenance of air filter is not an exaggeration. In the inhalation of air and fuel mixture before the air filter the air in the dust least squares, carbon and other debris, thus ensuring the cleanliness of the air inhaled. In fact, the volume per unit of fuel combustion, about the need for 10,000 per unit volume of air through the filter. And then a small dirt particles will also lead to internal engine parts and components related to the severe wear and tear.
Usually, manufacturers recommend regular maintenance of air filter replacement cycle for 48,000 km, and every 24,000 km to conduct a routine examination; the recommendation to maintain its conservative replacement cycle for 24,000 km.
The density of the atmosphere contains three basic particles of different pollutants, namely, dust, and carbon residue. In the open highway, the dust content of the more rural areas and low built-up areas. Dust concentration in the larger region, air filter inspection and replacement of higher frequency. Highways and traffic congestion in the region, because the concentration of emissions from vehicles, so the air in the carbon content was high.
Replacement of the oil during the day-to-day when, incidentally, check the air filter can be regarded as a good habit of the best of both worlds. At this point, won the filter, carefully read the depths of its folds inside. In some cases, appears to clean the external filter, but it is very dirty inside, and must immediately be replaced at this time.
Channeling PCV system will leak into the crankcase of the introduction of mixed-gas intake system, and then in the combustion chamber for secondary combustion.天长日久, oil, gasoline and other concentrates in the PCV valve into the internal deposition of colloidal sludge, resulting in PCV valve plug, resulting in improved internal crankcase gas pressure. Pressure led to the upgrading of the oil from the seal or gasket leakage Department, resulting in additional leakage of oil consumption and engine failure and so on. In addition, to increase the pressure on the crankcase vapors through the PCV make sticky oil and HC compounds have the air filter particles will inevitably reduce the accuracy of its filter. When the adhesion of foreign matter can not be completely closed PCV not appropriate amount of air will be the introduction of the combustion chamber, thus diluting the air / fuel mixture, which eventually led to the deterioration of motor vehicles and easy off idle performance.
The majority of manufacturers to provide normal maintenance of the PCV valve replacement cycle for the recommended 96,000 km; conservative replacement cycle for the maintenance of 48,000 km. In any case, check the air filter at the same time, be sure to test whether PCV valve plug and bonded. Ford PCV valve replacement cycle based on the recommendation of the different specific models for the 9.6 ~ 160,000 km range; GM also provided according to different models corresponding recommended PCV valve replacement cycle, the more broad range. When you on the ongoing maintenance of the vehicle replacement cycle of PCV valve doubts, please timely access to information on the owner's manual or maintenance. valve
