The car engine is the heart of the car and plays a key role in starting the car. Routine maintenance is essential. How to maintain the car engine?
Change the oil and filter regularly
The oil quality of any quality grade of lubricant will change in the course of use. To avoid malfunction, oil should be changed regularly according to the use situation, and the oil quantity should be moderate (generally the upper limit of the oil gauge is good).
Use the appropriate quality grade of lubricant
For gasoline engines, SD-SF gasoline engine oil should be selected according to the additional devices of the intake and exhaust system and the conditions of use; diesel engines should be selected according to the mechanical load of CB-CD diesel engine oil, and the selection standard should be no less than the requirements specified by the manufacturer.
Clean the tank regularly
Rust and scale can restrict the flow of coolant through the cooling system and reduce heat dissipation, leading to engine overheating or even engine damage. Therefore, water tanks should be cleaned regularly to remove rust and scale.
Maintaining three filters
The three filters are the air filter, oil filter, and gasoline filter. The third filter serves to filter the air body, oil, and gasoline from the car engine, thus protecting the engine and improving its efficiency.
Keep the crankcase well-ventilated
Most gasoline engines are now equipped with PCV valves (crankcase forced ventilation), but contaminants in the fugitive air can be deposited around the PCV valves and may clog the valves. Therefore, it is important to clean the contaminants around the PCV valve regularly.
Clean the crankcase regularly
During engine operation, high-pressure unburned gases in the combustion chamber, acids, moisture, sulfur, and nitrogen oxides enter the crankcase through the gap between the piston rings and cylinder walls and mix with the metal powder produced by the wear of the parts to form sludge. Therefore, the crankcase should be cleaned regularly to keep the engine interior clean.
Clean the fuel system regularly
Regular cleaning of the fuel system to control carbon buildup will keep the engine in top shape.

How to clean the engine
Cleaning and maintenance of the engine lubrication system
In the process of automobile driving, as far as the engine lubrication system is concerned, the deposition of oil, oxides of parts and pipes, wear particles of metal parts, dust brought by gases and so on. Will continue to deposit into sludge, grease, colloid, and carbon. Over time, these substances in a variety of parts, piping, and valve mechanisms to form an adhesion layer and accumulation layer, will seriously impede the smooth flow of the lubrication system, reduce the heat dissipation function of the parts, increase the wear and tear of the connected parts, reduce the work efficiency. Therefore, the cleaning and maintenance of the engine lubrication system is particularly important. The specific usage is to pour the cleaner into the crankcase, idle for 5-10 minutes,and then discharge the old oil.
At this time, the sludge, scale, and carbon in the lubrication system will be discharged with the old oil fully decomposed, but it should be noted that the oil filter must be replaced at the same time.
Recommendation: This cleaning and maintenance is suitable for oil change, after cleaning can be added to the oil protector, which can effectively extend the service life of vehicle parts and enhance the engine power. Engine fuel system cleaning and maintenance.
Carbon buildup occurs on fuel injectors, spark heads, valves, cylinder heads, piston work surfaces, and piston ring grooves when an automobile engine is operating. Over time, carbon buildup occurs in the form of colloidal deposits, which can lead to reduced combustion chamber volume and decreased efficiency. There are many uneven hot spots in the combustion process, causing the mixture to burn prematurely, resulting in reduced efficiency, incomplete combustion, and increased exhaust emissions. Poor oil supply and ignition, unstable idling, misfire, and popping; blocked piston ring grooves lead to poor cylinder lubrication, which in turn pollutes the lubrication system, clogs the oil circuit and oil filter, etc.. So the engine fuel system needs to be cleaned and maintained, there are mainly two different ways of cleaning: one is directly “cleaning agent” according to a certain percentage of the fuel tank, in the normal driving condition of the car for the internal cycle of cleaning; another way is the engine idling needs to be cleaned with a special device, and the final decomposition of carbon colloidal with the exhaust gas discharge.
Recommendation: After cleaning, the fuel filter should be replaced in time. Every 10,000 kilometers, the car should be regularly cleaned and maintained.

Top 10 Misconceptions About Engine Repair
Failure to maintain car engine on time
People usually like to spend a lot of money on modifications, but it’s easy to neglect the scheduled maintenance of the engine. According to experienced auto mechanics, poorly maintained engines cause 50% of the total breakdowns in the cars they deal with repair. This shows that engine maintenance can play a vital role in extending the life of your vehicle. And of course, it will minimize the unnecessary damage you would otherwise have to do with the term “supportive restoration”.
Reminder: During regular maintenance, not only the engine should be maintained, but also some inspection and maintenance of the relevant parts of the engine should be carried out when driving in some particularly humid or dusty areas.
Blindly removing the engine thermostat
If the thermostat is blindly removed because of the high engine temperature, the coolant can only be circulated in a large way, and the cooling intensity cannot be adjusted, making it difficult to ensure that the engine works at the right temperature. On the contrary, the engine often works at low temperatures, resulting in reduced engine power, accelerated wear and tear, and increased fuel consumption. If the engine temperature is still high after the engine thermostat is overhauled or replaced, the other parts of the cooling system should be overhauled and the thermostat should not be removed.
Engine idle temperature rise
When idling and warming up, due to the low rotational speed, the oil pump can not press the lubricant into the lubrication surface quickly, and the oil pressure is also low, so that the moving parts of the engine work in a dry friction or semi-dry friction state. Due to poor fuel atomization at low temperatures, the unburned fuel rushes into the crankcase, washing away the oil film on the cylinder wall, which will also accelerate the wear of parts. Therefore, after a few seconds of the engine starting, the engine should be warmed up at a fast idle speed to improve the lubrication conditions of the engine.
Engine temperatures are not afraid to go high or low
Some people think that the engine temperature is not afraid of high or low when driving. When the engine temperature is low, it is also very harmful. Only driving at the normal temperature specified in the automobile instruction manual can ensure the service life of the engine.
Bake the oil base with a blowtorch
Baking the bottom of the oil with a blowtorch in winter will not only cause the additives in the oil to undergo chemical changes and lose their original properties but will also deform the oil viscosities and the bottom of the oil, which can easily cause a fire. The best way is to choose the right engine oil according to the lowest local temperature in winter. If there are conditions, it is best to park the car in the garage with thermal insulation facilities. The more advanced cleaning methods are ultrasonic cleaning and nuclear spray cleaning, but the most common and simplest methods are physical and chemical cleaning. These two methods can also be used together.
The tighter the pump fan belt, the better
The tighter the belt, the better. Over-tightening the belt will not only cause it to stretch or break, shortening the service life of the belt, but will also lead to deformation and bending of the generator shaft and the water pump shaft, and early damage to the bearings due to over-tensioning. The tightness of the automobile engine fan belt should meet the technical requirements. Generally speaking, the deflection of the common belt assembly is 10-15 millimeters.
Car oil deterioration, bad oil filter element
The oil quality of different grades of lubricants changes during use. After traveling a certain mileage (parameters, pictures, inquiries), the performance will deteriorate and may bring various problems to the engine. To avoid these failures, the oil should be changed regularly in conjunction with the use of oil, and the amount of oil should be moderate. It is generally best to be between the upper and lower limits of the oil gauge.
As oil passes through the holes in the oil filter element, solid particles and viscous material in the oil can accumulate in the filter. If the filter is clogged and the oil cannot pass through the element smoothly, it may burst the element or open the safety valve and pass through the bypass valve, still bringing dirt back to the lubrication area, which will accelerate engine wear and intensify internal contamination. Therefore, it is equally important to change the oil filter element regularly.
Reminder: Don’t underfill your oil, but don’t overfill it either. It’s not true that the more expensive the name-brand synthetic oil, the better. The oil that suits your car is the best.
Clogged air filter element
The air intake system of an automobile engine is mainly composed of an air-air cartridge and an intake tube. Depending on the usage, the air body cartridge should be cleaned regularly. The available method is to blow a high-pressure air body from inside to outside to blow out the dust in the filter element. Since the air cartridge is paper-based, you need to pay attention to the air pressure when blowing to avoid damaging the cartridge. Empty in general, the air filter element is cleaned 3 times to be replaced with a new one, cleaning cycle can be based on the daily driving area of the air quality empty to decide.
Reminder: It is also important to purchase a positive parts air body cartridge from a good quality manufacturer.
The intake pipe is too dirty
If the vehicle is often driven in dusty road areas with poor air quality, care should be taken to clean the intake pipe to ensure smooth air intake. The intake pipe is very important to the normal operation of the engine. If the intake pipe is too dirty, it will lead to a decrease in efficiency, so that the engine cannot run in the normal power output range, and aggravate the wear and aging of the engine.
Reminder: Stay away from dusty areas as much as possible. Also, air adjustments should be replaced.
Excessive sludge in the crankcase
When the engine is running, the high-pressure body in the combustion chamber, acid, moisture, sulfur, and nitrogen oxides through the gap between the piston ring and the cylinder wall into the crankcase, so that it is mixed with the metal powder produced by the wear of the parts, the formation of oil sludge. Oil can be suspended in a small amount of oil sludge, when the equivalent is larger, it will be precipitated from the oil, blocking the filter and oil holes, making it difficult for the engine to lubricate, thus aggravating engine wear. In addition, when the oil is oxidized at high temperatures, varnish, and carbon will be formed and bonded to the piston, increasing oil consumption and reducing engine power. In severe cases, the piston rings will be blocked and the cylinder will be pulled.
Reminder: To reduce sludge production, it is essential to use good quality fuel, so vehicle owners are advised to try to go to genuine gas stations. It is also important to use good quality lubricants and change the lubricants and filters according to the maintenance intervals specified by the manufacturer. In addition, please check your car’s oil level frequently and replenish it as soon as possible when it is low.
