Common faults and solutions of automobile engines

If there is a lot of coolant, the engine thermostat, fan should be checked The radiator is out of order. The problem of engine overheating requires car drivers to master basic common sense and maintenance methods. The engine should be regularly maintained and inspected.

dissipationExcept for the special odor generated by the engine, during the use of the vehicle, if a pungent smell or burning smell is found in the engine compartment, you should stop immediately, check whether the lines around the engine have been softened or charred, and repair the charred or short-circuited lines in time to avoid larger safety accidents.

In our daily maintenance work, the most common engine failures include abnormal vibration, carbon accumulation, oil leakage, water leakage, high temperature, oil burning, oil increase, abnormal noise, engine fire, inability to start, etc. The engine shakes abnormally. Any engine will shake when it is working. This is determined by the characteristics of the engine structure.

"Oil into water" and "water into oil" are two faults of different nature. "Oil into water" is a problem with the engine itself, while "water into oil" is mostly caused by engine accessories, and the nature of the fault is different.Solution: You should go to the repair shop for replacement and repair in time.

As the use time of the car increases, the wear of the engine will gradually increase, resulting in an increase in fuel consumption. In addition, it may also be caused by the failure of the fuel supply system or poor driving habits.

Common faults and maintenance methods of automobile engines.

1. The engine cannot be started; 2 engine stall failure; 3 engine idle failure; 4 mixed gas thin failure; 5 acceleration failure 1 engine failure (1) failure phenomenon: turn on the ignition switch, turn on the ignition switch to the starting position, start The machine can't start.

2. Fault 1: Engine overheating fault. Due to the special structure of the car engine, it is easy to have excessive coolant temperature during operation. Once the coolant temperature exceeds the normal value, the engine cannot dissipate heat normally, which will cause the engine to overheat and affect the normal operation of the engine. Fault 2: The smell of the engine compartment.

3. Common faults and elimination methods of automobile engines: diagnostic elimination methods and procedures.1 Start gear, the starter and engine cannot run, and the start-up system fault should be detected.

4. There are many reasons for abnormal jittering of the engine. The most common is idle jitter caused by dirt on the throttle valve. Others include poor work of spark plugs, damage to the ignition coil, mechanical failure of the engine, etc. In addition, engine foot damage is also one of the common causes of engine jitter failure.

10 common faults and handling methods of automobiles

Oil leakage of motor vehicle oil pipe joints, such as oil leakage of engine oil pipe joints, is mostly caused by the unsealing of the oil pipe horn and oil pipe nut. You can wrap cotton yarn under the horn, and then tighten the oil pipe nut and oil pipe joint. Bubble gum or maltose can also be chewed into a paste, applied to the socket of the oil pipe nut, dried and sealed.

"Oil into water" and "water into oil" are two faults of different nature. "Oil into water" is a problem with the engine itself, while "water into oil" is mostly caused by engine accessories, and the nature of the fault is different. Solution: You should go to the repair shop for replacement and repair in time.

If the vehicle has a flat tire, don't step on the brake in a hurry. It is easy to lose control. The correct way is to hold the steering wheel and slow down slowly.

Solution: Pulled and dragged by other vehicles. Borrow the power supply of other vehicles to start. Use the downhill to start.

The author now summarizes the common faults of the car engine as follows: 1 The engine cannot be started (1) Fault phenomenon: turn on the ignition switch, turn the ignition switch to the start position, and the engine cannot start.

This is because the rubber limit block fixed in the groove of the steering machine has been completely damaged. After reinstalling the new limit block, the fault completely disappears. Generally speaking, such a fault can only be solved by the repair shop. Except for the expensive disassembly fee, the limit block is basically worthless.

What are the faults of the car engine?

There are many reasons for abnormal jitter of the engine. The most common is idle jitter caused by dirty throttle valve. Others include spark plug malfunction, ignition coil damage, engine mechanical failure, etc. In addition, engine foot damage is also one of the common causes of engine jitter failure.

Fault phenomenon: If the engine speed is unstable, the power is obviously insufficient, and there is a tempering phenomenon, it can be considered that the engine has a fault of excessive mixed gas.

Fault 3: Abnormal color of exhaust gas emission. Whether the car engine is faulty or not, there is still a little obvious performance. Analyze engine faults from abnormal exhaust colors. The color of the exhaust gas after normal combustion of gasoline should be colorless, but when the engine fails, the color of the exhaust gas will change.

Common faults and solutions of automobile engines

Eliminate the special smell generated by the engine During the use of the vehicle, if you find a pungent smell or burning smell in the engine compartment, you should stop immediately and check Whether the line around the motive is softened or charred, and the charred or short-circuited line is repaired in time to avoid greater safety accidents.

Aging of gasket: engineAfter long-term use, the sealing gasket (such as cylinder head gasket, valve cover gasket, etc.) is easy to age and crack, resulting in oil leakage. At this time, the corresponding gasket needs to be replaced.

"Oil into water" and "water into oil" are two faults of different nature. "Oil into water" is a problem with the engine itself, while "water into oil" is mostly caused by engine accessories, and the nature of the fault is different. Solution: You should go to the repair shop for replacement and repair in time.

The common faults of automobile engines are summarized as follows: 1 engine cannot start; 2 engine stall fault; 3 engine idle failure; 4 mixed gas failure; 5 acceleration failure 1 engine cannot start (1) fault phenomenon: turn on ignition Turn it off, turn the ignition switch to the starting position, the engine can't start.

Faults and solutions commonly encountered in the engine: faults. ( 1) Fault phenomenon: Turn on the ignition switch, turn the ignition switch to the start position, and the engine cannot start.
