Car daily maintenance common sense

2020-03-18  From: Guangdong Fusen Auto Parts Manufacturing Co., Ltd. Browsing times:15

The engine is the heart of a car. If the engine breaks down, the car often can't move. The economy, power, emission and environmental protection of the whole car are all related to the operation of the engine. Therefore, the maintenance of the engine is an important task of car maintenance.

Automobile production enterprises are generally opposed to the user disassembly and repair, emphasizing that the user to send special repair station to repair. What the user needs to do is to correctly use the operation and often timely maintenance, the so-called "seven separate maintenance, three repair", maintenance to improve to a strategic height to treat. Hubei heli special vehicle manufacturing co., LTD. Through years of long-term experience accumulation, summed up a set of car engine maintenance methods, hope to be able to help the majority of users.


Good driving skills and careful observation

1. Avoid low-lying, flooded roads

Heavy rain after the road is often water, then do not drive hard to rush, so as not to cause serious damage to the engine. Because once the engine sucked in the water, the combustion chamber was filled with water, and the rapidly rotating crankshaft and connecting rod mechanism pushed up hard, and the water was an incompressible body, the huge inertia force often broke the connecting rod. The cylinder body of high temperature encounters cold water suddenly also easy to cause the cylinder body to crack, and the electric control part of the electric injection engine that the computer controls if infiltrate water will form short circuit, cause the component even the computer damage, the loss is heavy. Therefore, in case of a rainstorm, you are advised to sit tight and wait. Drive to higher ground and wait for the water to recede. Don't try to rush through the water by any chance.

2. Add fuel when fuel is insufficient

There is an electric oil pump in the tank to deliver fuel to the engine. When the motor works, it heats up. When it sinks into the fuel, the heat is cooled by the surrounding fuel and it can run for a long time. But when the tank is seriously short of fuel, the oil pump is exposed to the air, the motor temperature gradually increased, the motor is easy to burn out. Therefore, when the fuel gauge pointer reached the warning zone to timely add fuel.

3. The starter cannot be used frequently in a short time

Sometimes, for some reason, the engine does not start, and the driver usually starts frequently. In fact, the starter's consumption of power is very large, generally to several hundred watts, serious consumption of battery energy reserves. The engine does not fire there is no power supplement, the battery is vulnerable to damage. So when you can't start the engine after a few fires, check the cause, eliminate the problem, and then start again.


Second, develop the habit of active inspection and maintenance to choose the appropriate lubricating oil

1. Learn more about the performance of the car

Men like to repair or modify their cars in their spare time. Of course also make some small creation and invention, anyway buy spare parts convenient. Build your own computer or design and create some electronics, like the current do-it-yourself fashion. Boys 13, four years old to steal the car, with his father to repair the car, to the age of majority, but also to drive everywhere, to the structure of the car, performance has been like the palm of one's hand.

2. Check, add and replace oil.

Engine oil is of special importance to the engine, because the engine speed has reached six or seven thousand RPM in cars, and even ten thousand RPM in racing cars. The linear velocity of piston movement is tens of meters high, and it is carried out under high temperature and pressure. The engine will soon break down if there is no suitable high grade oil as lubricant. Because the oil in the high temperature will have part of the volatile, so often through the oil gauge to check the amount of oil, when insufficient to add in time. However, it should be noted that the new oil must be the same model. Otherwise, two kinds of chemical composition of different oil mix, but will produce a chemical reaction, make the oil performance bad. The choice of engine oil depends on local temperature conditions. When the engine is running at high speed, there are often some metal chips and impurities fall down, the oil will be used for a long time, so, timely replacement is necessary. The time of oil change is clearly stipulated in all kinds of cars, generally after the running in period of 1000 to 1500 kilometers, and after every run of 5000 to 8000 kilometers. In the daily inspection, if found that the oil thickened, blackened, indicating that the oil has been bad, also need to be replaced in time. In the region where the temperature difference is large, summer, winter, the need to replace the corresponding brand of oil.


Third, pay attention to the maintenance of fuel system

1. Try to use reliable fuel oil and add fuel additives when necessary

This is particularly important for electric injection engines. This is because the temperature in the electric injection channel may reach more than 200 degrees, which makes the injection nozzle, valve stem and intake valve above the easy formation of carbon and glue, resulting in lax valve closure, cylinder pressure drop, resulting in valve cold adhesion, nozzle oil channel blockage. Fuel additives contain antiknock agent, antiwear agent, combustion agent, cleaning dispersant, it can effectively remove the accumulation of carbon and gum fuel system, improve fuel combustion speed, reduce exhaust pollution. If you just use high grade gasoline in big cities, it's not a big problem. But if you drive to a small town to fill up, add a bottle of reliable fuel additives.

2. Clean the oil system regularly, and use the fuel oil cleaning method without disassembly.

Although many cars use fuel additives, they still produce carbon deposits and gum, so every 20, 000 to 25, 000 kilometers the system must be thoroughly cleaned. Now more regular auto repair plants are equipped with non - disassembly fuel cleaning equipment. Say also very simple, connect it with oil circuit, input specific chemical clean agent, will engine idle run for a period of time, clean agent can accumulate charcoal to soften, decompose, glue and oil emulsify, dissolve, through combustion, discharge machine. It is reported that a car repair shop in the mainland cleaned 50 car engines with this method and achieved remarkable results, the average engine output power increased by 26.37%, fuel saving 11.20%, CO displacement decreased by 63.40%, HC displacement decreased by 59%, the effect is very significant.


Keep the engine assembly clean

1. Clean the filter element of the air filter regularly, and replace the filter during the second warranty period

Every 1000 kilometers or so, the filter element should be removed from the air filter, with compressed air from inside to outside the dust and other dirty things blown clean. Some cars have a dust cup at the air inlet, also check frequently to dump the dust. Three filters is to point to: fuel, oil and air these three filters, and oil filters are generally coarse filter and fine filter two, the car two warranty when the replacement. Different areas, different road conditions, cleaning and replacement time is also different.

2. Check and replenish coolant

If the level of the coolant in the storage tank is lower than the lowest scale line, the coolant of the same variety shall be supplemented, and distilled water may be used to replace it if necessary. To pay attention to, one must wait for the temperature to drop before opening the cover, or the high temperature water spray out very easy to burn people.

3. Adjust valve clearance

After a period of time the car will sometimes hear the "click, click" in the engine, this is often the valve and valve tappet between the gap between the big, then to adjust the gap. But modern, newer car engines already use hydraulic tappets that automatically eliminate gaps and solve problems.

4. Inspect and clean platinum contacts

After the platinum contact on the distributor is used for a period of time above can have ablative, can cause resistance to increase, spark plug spark energy drops, make engine output power drops, this is about to use fine sandpaper to grind that oxidation layer gently. However, it should be noted that the contact area should not be less than 80%.

5. Check spark plugs often

If the engine is found to have lost power, one of the possible reasons is that the spark plug needs to be overhauled.
