Causes of insufficient vehicle power:
1. Fuel system causes:
Due to blockage of the fuel tank cover vent, the fuel tank switch, fuel filter and fuel tank hose oil between the carburetor and the carburetor is partially blocked and cannot supply the required amount of oil, causing the mixture to be too thin and the engine to run weak.
2. Ignition System Causes:
Ignition timing is inaccurate and ignition is premature, causing premature combustion and knocking of the combustible mixture. Due to a fault in the ignition system
the spark plug misfires or the spark plug emits weak sparks.
3. Cylinder compression pressure:
Severe wear of the piston, piston ring and cylinder leads to an increase in the gap between the piston, piston ring and cylinder
3. p>
and sealing Performance deteriorates, causing air leaks in the cylinder head and reducing cylinder compression pressure.
4. Engine overheating:
Incomplete combustion of the combustible mixture, for various reasons, causes excessive carbon deposits in the combustion chamber, resulting in
poor heat dissipation. causes overheating due to increased engine load.
5. Lubricating oil problem:
There is too much or too little lubricating oil in the crankcase, the lubricating oil is deteriorated or dirty, and the lubricating oil passage is blocked, which affects the power of the engine.
Daily automobile maintenance:
1. Car Engine Maintenance
Car engines need to be cleaned at the appropriate time. Because long-term use will form a thick layer of carbon deposits on the surfacethis of the engine, which will cause greater corrosion of the rubber parts of the engine.
2. It is necessary to prevent gasoline and water from evaporating.
In summer, the temperature is generally relatively high. This allows gasoline and water to evaporate more easily than usual. Since the water tank and fuel tank need to be checked frequently, gasoline and water should be added in time when there is less gasoline and water.
3. Pay attention to hygiene inside the car
Summer is the season when bacteria multiply most quickly, so the interior of the car should be kept clean, especially the car seat cushions, steering wheel covers and car floor mats Items that get dirty easily.
4. Car windshield wipers need to be replaced
When driving in rainy days, you should pay attention to whether the windshield wipers are in good conditiont. used for a long time will age. For driving on rainy days, there are better ones. For driving vision, it is best to replace the car's windshield wipers every one to two years.
5. Car mats need to be updated
A good car cooling mat is an important choice for car sun protection in hot seasons. Choose a cool carpet that is not too slippery. To avoid traffic accidents caused by body slipping while driving.
6. The car body also needs to be maintained
Ultraviolet rays can also cause serious damage to the car, such as penetrating car paint. Everyone may have noticed that after a white car is exposed to the sun for a long time, the body color will obviously become lighter and more yellow. Therefore, wax and seal vour car in summer can protect your car.
What is the reason why the car has difficulty starting?
Common reasons for difficulty starting the engine:
1. Ignition difficulty caused by carbon deposits in the car, accompanied by a slight jerk at idle. Clean the throttle valve and clean it. carbon deposits in the intake tract, cleaning the injectors may solve the problem.
2. The ignition energy of the spark plug is low. In order to save money, some car owners do not replace the spark plug after the maintenance period, which will cause the ignition energy of the spark plug to drop significantly. Misfires. In addition, many current engine designs are mostly cylinder-based. Internal direct injection places higher demands on the spark plugs.
3. Insufficient low pressure in the pipeite fuel. Insufficient oil pressure in the low pressure oil line directly results in secondary ignition of the engine. The specific reason is that the first ignition fails due to low pressure. The oil line increases oil pressure and may fail the second time. Specific parts to check: fuel pressure regulator, fuel pump, fuel filter element and internal lines.
4. Loss of battery power. Loss of battery power is more common. Generally, the car owner's first reaction when the car cannot start is that the battery is dead. The solution is also very simple, just find a car or another battery to power it.
5. The exhaust pipe is blocked. Exhaust pipe blockage usually rarely happens unless by chance or someone is playing a prank, but this situation iseasier to check.
6. The mixture is too rich or too thin. Many auto repairers know a secret. What should I do if the car won't start and there are no problems with other parts? The old master will spray the detergent on the accelerator and start the car, and the car will start easily without trying repeatedly (car owners are not recommended to do it themselves).
7. Engine timing is incorrect. If the engine timing does not match, the engine will definitely not be able to start the car, and many car engines use timing belts. , but some When replacing the alternator belt on certain types of engines, it can cause a shift in speed, preventing the vehicle from starting.
