What are the reasons why the car is not good

The cold car is not good to hit the car, it may be the oil pump pressure relief or spark plug problem, the general hot car is difficult to get on the car is not much, it should also be a spark plug.

The inspection items such as failure to start, unstable idling, high and low speed, abnormal oil supply and other inspection items are as follows: 1. The battery voltage of the car is low; Specific detection method: test the battery voltage with a three-purpose meter voltage level, if it is below 10V, it is recommended to replace it.

If it is around 11V, it is barely used; Be prepared for replacement. It can be used above 12V; 2. Check whether it is caused by carbon deposits; If you travel about 20,000 km, focus on checking and cleaning the throttle; 3. Inspect, test and replace spark plugs; 4. Confirm the quality of the gasoline added; 5. Detecting the ignition switch; 6. Test and detect the starter, gasoline pump, sensor and other related components of the starting and oil supply system; 7. After powering on, do not start immediately, wait for 30 seconds to 1 minute, and then ignite; See if it works; Regardless of any of the above situations, pay attention to the time when the car cannot be hit once, be sure to play again after an interval of 15-30 seconds to protect the battery but not generate power and prolong its service life.

Hello, the car does not get on the car, it is very simple, there are two reasons, one is the circuit ignition, the other is the oil circuit problem, you first check the circuit from the spark plug, the high-voltage line, the ignition controller and the ignition switch, etc., you are checking the oil circuit from the fuel injector, gasoline filter, oil pump, under the look of the pipeline is not good, you just disassemble the timing belt, look at your ignition timing.

Precipitation of oil in the air cooling, increasing the burden on the motor; The battery time is long and there is a lack of electrolyte; The motor is not serviced or should be replaced; Should be done regular maintenance you did not do for the sake of causing the oil and three filters to be dirty.

Hello. There are many reasons for this, such as dirty throttle valves, spark plug problems, fuel quality problems, oil problems, and so on. Hope it helps.

The scooter is not good to start when it is cold; These 6 places are the biggest factors that cause bad fires, teach you simple repairs.

There are generally two types of car engine starting difficulties:

1. The starting performance of the engine gradually deteriorates, and the starting time is getting longer and longer;

2. The engine has always been very good in starting, and it suddenly deteriorates one day.

3. The engine starts to deteriorate slowly, mostly because the battery performance is not good. In this kind of car, when turning the ignition switch to start the engine, the speed of the engine is instantly high, and then the starter appears to be underpowered, so that the engine speed is extremely low, and it takes a long time to start the engine. In this case, the old battery must be removed as soon as possible and replaced with a new one.

After the battery is replaced, the starting performance of the engine can be improved immediately after the battery is replaced.

4. If the starting performance of the engine has been poor for a long time, it is likely that there is a problem with the ignition system or fuel supply system. For example, the spark plugs, high-voltage wires, ignition coils, etc. in the ignition system are faulty, and the carburetor in the fuel supply system is poorly adjusted. To solve this kind of problem, you need to have some skills, and it is best to ask a professional repairer to help check it before the problem worsens.

If you don't have the skills to do it yourself, it's best not to make adjustments.

The reason why it is not good to drive in winter. It is because of the cold winter, the temperature is low, and the oil temperature rises slowly, which makes it difficult to drive.

1. The battery power is insufficient;

2. The high-voltage coil is out of power;

3. The spark plug does not ignite;

4. The fuel injector is dirty;

5. The oil circuit is blocked (or there is air);

1. The spark plug is broken.

2. There is carbon deposition in the valve.

3. The battery is dead.

4. The starter is broken.

After a long time, it is estimated that carbon deposits are generally added with bad oil! It's the battery that is dead, just connect it to the fire.

The most common is that there is air in the oil circuit, and there is not enough starting speed.

It's too cold, there's no oil, the engine is broken (old), you didn't screw it in place......

There are several reasons why the car cannot be driven: the exhaust pipe is frozen, and the appearance is characterized by the high pressure of the fog cylinder, the oil supply and power supply are normal, and the car cannot be driven. This can easily happen in vehicles that are used particularly infrequently.

For example, when the home is very close to the unit, the water vapor after the combustion of the engine freezes at the muffler of the exhaust pipe. After a short drive, yesterday's ice did not completely melt, and today the ice is frozen again. After a long time, it will affect the exhaust, or the start-up is not serious.

The solution is simple. Keep the car in a warm environment and start naturally when it freezes. If the solution is thorough, you can run high speed in time.

Valve glue In winter, especially after the use of unclean gasoline, the non-combustible glue in the gasoline will accumulate near the intake and exhaust valves and combustion chambers, which will cause difficulty or even no starting in the cold morning. Emergency method: Drop some oil into the combustion chamber and start it generally.

After starting, go to the repair station for dismantle-free cleaning. In severe cases, the car needs to be repaired and disassembled to clean the cylinder head. The ignition system is not easy to use, especially in cold weather.

Due to the low intake temperature, the fuel is poorly atomized in the cylinder. If the ignition energy is insufficient, there will be overflow in the cylinder, that is, too much oil will accumulate in the cylinder, and the ignition limit concentration will be exceeded, and it will not be able to drive. Contingency Method:

Unscrew out the spark plug to wipe off the oil between the electrodes, reassemble it and get on the car. The thorough way is to check the ignition system and eliminate the causes of low ignition energy, such as spark plug electrode gap, ignition coil energy, high-voltage line status, etc. Gasoline flow obstruction is characterized by the absence of oil pressure in the supply pipe of the elastomotor engine.

This happens in the morning when the temperature is very low, and is caused by long-term fouling in the fuel pipes. When the temperature is particularly low, water and debris mix together, making the fuel line impassable and thus unable to start. Contingency Method:

Put the car in a warm environment and the car will start in a moment; Or clean the oil stain completely and solve it. The loss of battery power is characterized by the starter starting to rotate, but not fast enough, that is, it is weak, and then the starter only clicks. In winter, the temperature is low, and forgetting to turn off individual electrical appliances will cause the vehicle to fail to start, especially in winter, if the short distance is used for a long time at low speed, the battery voltage will be lower than the rated value, and the vehicle will not be able to start and drive normally.

If something happens, call the service station for help**, or find a car to check, or check the fire for a while, and then be sure to go to the service station to recharge the battery.
