Car maintenance is like adopting a daughter-in-law

Maintenance projects should be kept in mind.

There is a saying that car maintenance is like raising a wife. Talking about car maintenance, although marriage has a running-in period of 3-5 years, after the key running-in period of these years, married life will be like a duck to water and happiness will be incomparable! The same is true for car maintenance. A 30,000-kilometer car is also a critical period of maintenance. Let's take a look at how to maintain a car to be "tender".

The maintenance items of 30,000 kilometers include: mechanical filtration of engine oil, maintenance of lubrication system, inspection or replacement of air filter element, gasoline filter element and spark plug.

oil filter

Under the current air and climate conditions in China, the continuous oxidation of engine oil every 5,000 kilometers leads to the decrease of engine oil viscosity, which can no longer meet the needs of safe driving. Therefore, changing the oil every 5,000 kilometers (changing the oil filter when changing the oil) has become the common sense of most car owners.

lubrication system

However, the maintenance of lubrication system is a project that is easily overlooked by the majority of car owners. Sludge can be said to be the biggest enemy of automobile lubrication system. Excessive accumulation of sludge in lubrication system will greatly reduce the heat dissipation effect of engine oil and accelerate the aging speed of engine.

The main purpose of this maintenance is to clean up the sludge and carbon deposits in the engine. The protective agent can form a protective oil film inside the engine to protect all parts of the engine.

Air filter

Then there is to replace the air filter element and install it in front of the carburetor or intake pipe to filter out the dust and sand in the air.

The filtering effect of the air filter element will decrease every 10000 km, and larger air particles will enter between the piston and the cylinder, resulting in a serious "cylinder pulling" phenomenon. Therefore, it is necessary to replace the air filter regularly to ensure that sufficient and clean air enters the cylinder.

Gasoline filter element

The next step is to replace the gasoline filter, also known as the gasoline filter. Its main function is to filter out impurities in gasoline.

The filtering effect of the gasoline filter will decrease every 30,000 kilometers, so the steam filter should be replaced regularly. When replacing the gasoline filter, you must choose a good quality filter. Inferior filters are not only poor in material, but also poor in filtration effect. The filter layer inside is easy to fall off, blocking the oil circuit and causing abnormal pressure in the fuel system.

Spark plug

The last item is the spark plug. As we all know, spark plug is an important part of the ignition system of gasoline engine. The spark plug introduces high-voltage electricity into the combustion chamber, making it jump over the electrode gap to generate sparks, thus igniting the combustible mixture in the cylinder.

The ignition performance of the spark plug will decrease every 30,000 kilometers of the general vehicle, and it will also bring about abnormal situations such as increased fuel consumption, substandard emission and incomplete combustion (smelly exhaust gas). Therefore, it should be replaced or inspected regularly.
