What is the reason why the car is a bit difficult to ignite?

There are many reasons why the car is very hard to ignite, and you can check the battery and spark plug at this time.

The service life of the battery is about 2-3 years, if the battery is used for a long time, or the car electrical appliances on the car forget to turn off, the battery will cause a loss of power, at this time the battery power supply is insufficient, the car ignition will appear very weak.

Spark plug carbon deposit.

Too much or malfunction, it will also cause uneven ignition, or no ignition, at this time, ignition will make the gas in the cylinder unable to burn, resulting in ignition difficulties.

In addition, if the fuel injector has too much carbon deposit, it will affect the fuel intake of the car, and the fuel intake of the car is insufficient, and the gas in the cylinder cannot be burned when it is ignited, so that it will take many turns to catch fire.

When a relatively old car is ignited, many of them will suddenly turn off. Most of the cases are caused by excessive carbon deposition and blocked air intake ducts, and the car shakes like a stall when the car is ignited, indicating that the air intake is insufficient to burn the gasoline in the cylinder.

If there is too much carbon deposit, the throttle.

Poor work will affect the fuel efficiency of the car. When the car is cold, the sudden situation will be more obvious, at this time you can clean the throttle, or replace the intake pipe.

What are the reasons for the hard ignition of the car in winter: 1. The fluidity of the engine oil is not good enough; 2. Caused by insufficient battery activity; 3. It may be that the exhaust pipe is frozen; 4. It may be a problem with antifreeze; 5. It may be that the throttle has too much carbon deposit.

The car is a bit of a strain to ignore, most likely due to the battery or spark plug.

Summary. The car was struggling to ignite. It's normal to burn it, which means that there are several reasons for this.

The first reason is first. Check whether the voltage of the battery is normal, not lower than 10 volts, lower than 10 volts means that the battery voltage is insufficient.

The second reason is. Excessive carbon deposits in the engine led to this. In this case, it is necessary to clean the valves and deposition the combustion chamber.

The third reason is that the gasoline pressure is insufficient, and in this case, it is necessary to check that the gasoline pressure is above the normal value.

The fourth reason is that the mixing ratio is incorrect, which leads to this situation, and there are many reasons for the wrong mixing ratio, such as air leakage and incorrect data from the oxygen sensor. This one needs to be passed. Diagnose the data flow of the computer for detection, and repair it with fault codes.

The car is very hard to ignite, and it is normal to ignite, what is the reason?

Hello, don't click to end, I'm textual to give you the full answer, 2-3 minutes.

It's normal to burn it, which means that there are several reasons for this. The first reason is first. Check whether the voltage of the battery is normal, not lower than 10 volts, lower than 10 volts means that the battery voltage is insufficient.

The second reason is. Excessive carbon deposits in the engine led to this. In this case, it is necessary to clean the valves and deposition the combustion chamber.

The third reason is that the gasoline pressure is insufficient, and in this case, it is necessary to check that the gasoline pressure is above the normal value. The fourth reason is that the mixing socks are not wrong, which leads to this situation, and there are many reasons for the wrong mixing ratio, such as air leakage and the data of the oxygen sensor is incorrect. This one needs to be passed.

Diagnose the data flow of the computer for detection, and repair it with fault codes.

The throttle also please wash the spark plug update time is not long.

This needs to check the reasons I mentioned.

This phenomenon occurs after the throttle has been washed.

That rematches the throttle.

Match the ementium. A dedicated PC is required for matching.

Good. If you feel that it has been helpful to you, please give a 5-star thumbs up when the question is over. The platform will send coupons, which can be used in cash next time.

There are many reasons for this, and at this time you can check the battery andSpark plugsThe service life of the battery is about 2-3 years, if the battery is used for a long time, or the on-board electrical appliances on the car forget to turn off, the battery will cause a loss of power. At this time, the battery power supply is insufficient, and the car ignition will appear very weak.

Spark plug carbon deposit.

Too much or malfunction will also cause uneven ignition, or no ignition. At this time, ignition will make the gas in the cylinder unable to ignite, resulting in difficulty in ignition. If the fuel injector deposits too much carbon, it will affect the amount of fuel intake of the car, and the fuel intake of the car is insufficient, and the gas in the cylinder will not be able to burn when it is ignited, so that it will take many turns to catch fire.

Points to note for car maintenance

1. Maintenance of automobile engine.

The car engine should be cleaned at the right time. Because long-term use will form a thick layer of carbon deposits on the surface of the engine, which will cause greater corrosion to the rubber parts in the engine of the engine.

2. Gasoline and water.

To prevent evaporation.

In summer, the temperature is generally high. So both gasoline and water evaporate more easily than usual. Because the water tank and fuel tank should be checked frequently, and when the gasoline and water are relatively small, they should be added in time.

3. Car mats should be updated.

A good car mat is an important choice for car sun protection in the hot season. Choose a mat that is cool and not too slippery. In order to avoid traffic accidents caused by body sliding while driving.

Summary. Excessive carbon deposition or failure of the spark plug can also cause uneven ignition, or no ignition. At this time, ignition will make the gas in the cylinder unable to burn, resulting in difficulty in ignition.

Hello, I have seen your question and am sorting out the answer, please wait a while

The car book grinding and igniting is very difficult to ignite and normal stools, there are many reasons for this situation, you can check the battery and spark plug at this time. The service life of the battery is about 2-3 years, if the battery is used for a long time, or the on-board electrical appliances on the car forget to turn off, the battery will cause a loss of power. At this time, the battery power supply is insufficient, and the car ignition will appear very weak.

Excessive carbon accumulation in the spark plug or failure of the slag core will also cause uneven ignition, or no ignition. At this time, ignition will make the gas in the cylinder such as potato digging unable to burn, resulting in difficulty in ignition.

In addition, if the fuel injector has too much carbon, it will affect the amount of fuel intake of the car, and the fuel intake of the car is insufficient, and when the fire is ignited, the precursor of the gas Zen grip in the cylinder skin will not be able to burn, so that it will take many turns to catch fire.

It's no problem to change the spark plug of the battery, but it still hasn't been solved.

How old is the car?

Check the high-voltage coil again, which is the ignition coil. Most of the time it was broken.

The car can not ignite after a while, probably because when the cold engine is started, the atomization effect of the injected fuel is not good, and a large amount of liquid fuel enters the cylinder. As a result, the mixture around the spark plug is too thick, and the car will not be able to hit if the fire limit is not reached.

The throttle is carbon deposited, and the purpose of stepping on the throttle is to increase the throttle opening and increase the air intake, but if the throttle is too dirty, it will limit the increase in air intake. Just like breathing, the nose is not breathing, the air inhaled into the lungs is reduced, and it is natural to be uncomfortable. At this time, it is necessary to clean the throttle valve to remove the carbon deposits on it and allow air to enter the cylinder more freely.

Second, there may be a problem with the fuel system. Fuel pump damage, poor oil circuit will lead to insufficient fuel, no years of lead enough fuel to participate in combustion, resulting in the concentration of the mixture is too low, in this case and the concentration is too high, the spark plug is also difficult to ignite the mixture, the car still can't hit.

Therefore, if you want to reduce the concentration of the mixture, you need to inject more air into the cylinder, generally speaking, it is not enough to drive the crankshaft by the starter to do the intake stroke, because the speed is not fast enough, and the suction of the cylinder intake is weak. These phenomena will cause the car to turn off and not catch fire, and wait for a while to hit the situation that it can be turned on again, and it is best to go to a nearby maintenance shop to check and eliminate the cause of the failure.

The following are the specific reasons for the difficulty of ignition in automobile engines: 1. Ignition difficulties due to carbon deposition in automobiles. There is also a slight shake at idle, and the throttle and fuel injector can be washed.

2. The ignition energy of the fire erector flower plug is weak. The spark plug is not replaced after the maintenance interval, resulting in a shortage of ignition energy of the spark plug when the ignition energy decreases severely. 3. The low pressure of the fuel circuit is insufficient.

The lack of oil pressure in the low-pressure oil circuit directly leads to the secondary ignition of the engine, and the fuel pressure regulator, gasoline pump, gasoline filter and internal pipelines are specifically checked. 4. The battery loses power. You need to find a car or other battery to take power.

5. The engine timing is wrong. The engine timing does not match the engine, and some models of engines may cause tooth skipping when replacing the generator belt, which will cause Yu Yutan to cause ignition difficulties.
