What is the reason for the slow ignition response of the car

Causes of ignition start delays.

1. The oil is not good: if the car suddenly starts normally to delay the start, then you must first think about whether you have changed to gasoline of different grades and gasoline in different places in the near future.

2. Carbon deposits in the car.

or dirty parts.

a. Throttle.

The carbon deposition of the throttle will affect the perception of the throttle and air intake, resulting in the lag or even error of the computer transmission signal, resulting in the vehicle not being able to start;

b. Fuel injector: It is easy to adhere some gum to the fuel injector, which will block the normal amount of fuel injection, resulting in poor atomization of gasoline, so that the ignition is delayed and the car is difficult to start;

c. Spark plug.

If there is a lot of carbon deposition in the spark plug or there is air leakage at the joint between the metal and the porcelain, it will cause poor ignition;

d. Battery: Dirty battery binding posts may also cause poor conductivity, which will affect ignition; Of course, the lack of battery power may also cause a delay in ignition start-up;

3. The starter relay is faulty;

4. The starting motor is faulty;

5. The viscosity of the engine oil is not suitable: for example, when the temperature is very low, the viscosity of the engine oil is high, resulting in slow oil circulation and dry friction of the machinery, so it is difficult to start, and at the same time, it is very harmful to the car;

6. There is a problem with the ignition switch;

7. Carbon canister solenoid valve.

Faulty: The ignition is weak after exposure, but there is no secondary ignition, generally there is a problem with the solenoid valve of the carbon canister, because the role of transpiration after gasoline exposure is particularly large, and the valve of the carbon tank valve is not well sealed, and it is easy to flood the cylinder that is the wet wall.

8. Ignition timing proofreading.

There is a problem; 9. a camshaft.

Sensor failure: In the case of confirming that there is no problem with the timing calibration, you can focus on checking whether the camshaft position sensor is working properly;

10. Insufficient oil pressure: gasoline pump pressure relief, poor fuel injector sealing, etc., will cause insufficient gasoline pressure, so that the ignition time will be prolonged;

Summary. The car starts delayed, and it is difficult to start, whether it occurs when the car is hot or cold, and it is inseparable from the three problems of oil circuit, circuit, and oil-electricity coordination. As long as the maintenance personnel think through these three aspects, they will be able to quickly find the crux of the problem; Also as a friend of the owner, according to the usual use of the car, and then compared with this article, I believe that I can also have a more accurate conjecture, and I will have more confidence in finding someone to repair.

Check if the battery is going to be replaced.

The reasons for the sluggish ignition of the car are as follows: 1. The ignition is sluggish in winter: the temperature is low in winter, and when the cold car starts, the temperature of the engine block is low, and the fuel is difficult to atomize, resulting in the fuel injected into the cylinder can not be fully mixed with the air, and the gasification rate of gasoline drops sharply.

In addition, the viscosity of the oil in the engine becomes greater in winter, and the resistance of the engine increases, which makes it difficult to start, or even cannot start. This is normal. 2. Slow ignition in summer:

When the life of the spark plug reaches its limit, the spark plug electrode gap is too large, which will lead to sluggish ignition. Cold car starts require high ignition energy, and if there is a problem with the spark plug, it is naturally difficult to start if the gas mixture in the gas cylinder cannot be ignited normally. The solution is to replace the spark plugs.

The slower ignition of the car may be a problem with the spark plug in the ignition system, such as the spark plug electrode gap is too large, and the service cycle reaches the limit will lead to slow ignition, and the spark plug can be replaced; At the same time, ignition retardation also involves damage to the oxygen sensor, air intake system leakage, throttle blockage, fuel pressure is too low, ignition is officially incorrect, cylinder compression pressure is low and other fault causes, which may lead to ignition retardation.

If the ignition of the cold car is slow to react, on the contrary, the ignition of the hot car is normal and it is likely to be related to the cold weather; In winter, the temperature is low, and when the cold car starts, the engine block temperature is low, and the fuel is difficult to atomize, resulting in the fuel injected into the cylinder cannot be fully mixed with the air, and the gasification rate of gasoline drops sharply.

The ignition of the car is delayed, this Wang Mang has something to do with changing to different grades of gasoline, and then the throttle is too dirty or the fuel filter is too dirty, and then the fuel injector is not cleaned in time.

It should be because of the aging of the wiring and the aging of the ignition device, and it is enough to replace it with a new set.

It may be that the oil pressure is not enough, the detection method: screw the key to the ON position (do not ignite) before ignition, switch back and forth a few times and wait for a few seconds, and then the ignition is normal or better, it is a problem of oil pressure.

What is the reason for the delay in the ignition of the car.

1. Reasons for ignition start delay 1. Oil is not good: If the car suddenly starts normally to delay starting, then you must first think about whether you have changed to gasoline of different brands and gasoline in different places in the near future. 2. Carbon deposits in the car or dirty parts A, throttle:

The carbon deposition of the throttle will affect the perception of the throttle and air intake, resulting in the lag or even error of the computer transmission signal, resulting in the vehicle not being able to start; b. Fuel injector: It is easy to adhere some gum to the fuel injector, which will block the normal amount of fuel injection, resulting in poor atomization of gasoline, so that the ignition is delayed and the car is difficult to start; c. Spark plug: If the spark plug has a lot of carbon deposit or there is air leakage at the joint between the metal and the porcelain, it will cause poor ignition; d. Battery:

Dirty battery binding posts may also cause poor conductivity, which can affect ignition; Of course, the lack of battery power may also cause a delay in ignition start-up; 3. The starter relay is faulty; 4. The starting motor is faulty; 5. The viscosity of the engine oil is not suitable: for example, when the temperature is very low, the viscosity of the engine oil is high, resulting in slow oil circulation and dry friction of the machinery, so it is difficult to start, and at the same time, it is very harmful to the car; 6. There is a problem with the ignition switch; 7. The carbon canister solenoid valve is faulty: the ignition is weak after exposure, but there is no secondary ignition, generally there is a problem with the carbon canister solenoid valve, because the effect of gasoline transpiration after exposure is particularly large, and the valve of the carbon canister valve is not well sealed, and it is easy to flood the cylinder, that is, the wet wall.

8. There is a problem with the ignition timing calibration; 9. Camshaft sensor failure: In the case of confirming that there is no problem with the timing calibration, you can focus on checking whether the camshaft position sensor is working normally; 10. Insufficient oil pressure: gasoline pump pressure relief, poor fuel injector sealing, etc., will cause insufficient gasoline pressure, so that the ignition time will be prolonged;

1. It may be because of the low fuel pressure, when the motor is first started, the mixture is too thin, so the engine is not easy to start. It is recommended that you can try it, open the key door to the instrument light before starting, hear the sound of the oil pump, wait until the sound is over, close the key door, and then repeat the above operation, about 2-3 times, until the sound of the oil pump is no longer the sound of the sound, but almost inaudible, and then start should be able to play at one time.

2. It is easy to have starting difficulties due to low temperature in winter, it is recommended to replace the special engine oil in winter and clean up the carbon deposits in the spark plug, which can solve the problem by 90%.

3. Look at whether the fuel injector has also been washed and the valve carbon deposit** are cleaned together, and then measure whether the fuel pressure is normal, and I feel that cleaning the fuel injector is the most effective.

4. The water temperature sensor is broken. In winter, if the water temperature sensor is broken, it will affect the fuel injection of the engine and make it difficult for the car to start.

5. The battery is broken. If the battery is broken, the battery will not be powered enough when it starts.

The slower ignition of the car may be a problem with the spark plug in the ignition system, such as the spark plug electrode gap is too large, and the service cycle reaches the limit will lead to slow ignition, and the spark plug can be replaced; At the same time, ignition retardation also involves damage to the oxygen sensor, air intake system leakage, throttle blockage, fuel pressure is too low, ignition is officially incorrect, cylinder compression pressure is low and other fault causes, which may lead to ignition retardation.

The car starts ignition slower than before.

If the ignition of the cold car is slow to react, on the contrary, the ignition of the hot car is normal and it is likely to be related to the cold weather; In winter, the temperature is low, and when the cold car starts, the engine block temperature is low, and the fuel is difficult to atomize, resulting in the fuel injected into the cylinder cannot be fully mixed with the air, and the gasification rate of gasoline drops sharply.

Hello [happy] I am an automotive consultant and I have received your question. We're sorting out the answers for you, so don't worry! Typing is slower, about 5 minutes for you, please wait for it!

Hello dear, I am glad to answer for you [happy] It is normal for the car to be too slow to ignite, and under normal circumstances, high idle speed of cold start is not a fault. Because the high speed of the engine after starting is intentionally controlled by the engine computer, its main purpose is to make the water temperature, oil temperature and three-way catalytic converter quickly reach the optimal working temperature, reduce the wear of the engine transmission, improve combustion efficiency and improve emissions. All cars have a high idle speed process when starting cold, and the lower the temperature, the longer the high idle speed will be maintained.

After ignition, the engine idle speed is generally between 1300-1500 rpm, and the sound of the engine is also very loud, as the water temperature gradually increases, the idle speed gradually decreases, and finally drops to the normal idle speed of about 800 rpm.

Difficulties in starting a car may be caused by the following reasons.

1. In winter, the weather is cold, the temperature is low, and the dryness leads to an increase in the viscosity of the engine oil in the car, which leads to the slowing down of the flow of the engine and increases the resistance of the automobile engine, which makes it difficult for the car to be ignited.

2. There is an internal fault in the engine of the car, when the engine of the car is used improperly, the wear and tear of the engine increases, resulting in insufficient pressure of the engine cylinder, resulting in the difficulty of ignition of the car.

3. In winter, due to the low temperature, the exhaust pipe of the car is frozen, which makes it difficult for the car to ignite.

Hello, just replace the spark plug in this case.

The main reason for the delay in the ignition of the car is that there is a certain failure of the starting equipment or the lighter itself, so there are certain safety hazards in the driving of the car at this time, so it must be repaired and replaced in time.

There are many things that need to be paid attention to in the daily maintenance of the car, so it is necessary to communicate with professional technicians and master the correct and safe maintenance methods, and it is necessary to learn and communicate with others, and you need to pay attention to the following points.

1.Keep your profile down when communicating.

I'm right", this attitude will only lead to the deterioration of the communication relationship and make it impossible for communication to continue. When communicating, it is best to keep your profile as low as possible, that is, to fully respect the opinions of the other party, and to express your opinions and opinions appropriately and not excessively. Even if you think that your statement is not wrong or there is a problem with the other party's opinion, you should first listen to the other party's words, different people have different ideas, the ability to express and understand is also different, there may be the other party's expression mistakes or their own understanding is biased, you should lower your posture and listen patiently.

2.Don't get emotional.

When communicating, it is important to keep a calm mind and not be emotional. Emotionally charged may make communication stuck halfway and unable to communicate, and even lead to abandonment and failure of communication. If you feel particularly irritable and restless in the process of communication because of your emotions, you will have to stop communicating and wait for a period of time to calm down before you can continue to communicate, which will actually make all parties in the communication unhappy.

3.Abandon your self-esteem when communicating.

Unnecessary self-esteem and pride can only become a stumbling block to communication, so at the very least, you should abandon your so-called self-esteem when communicating. Don't say "My self-esteem won't allow me to ......In that case, it will only make communication impossible.

4.Be open and honest with the person you're communicating with.

In the process of communication, it is very important to be honest with the person you communicate with, and there is no concealment, honesty is an important step for you to deepen the cooperative relationship through communication. First of all, you can make the other party believe in yourself through your own honesty, and then drive the other party to be honest with you, and then promote the smooth and happy communication.

1. If the car suddenly starts normally to delayed starting, then first think about whether you have changed to gasoline of different grades and gasoline in different places in the near future.

2. Carbon deposits in the car or dirty parts.

1) The carbon deposition of the throttle will affect the opening and closing of the throttle, and the perception of the air intake will also be weakened, resulting in the lag or even error of the computer transmission signal.

2) It is easy to adhere some gum to the fuel injector, which will block the normal amount of fuel injection, resulting in poor atomization of gasoline, so that the ignition is delayed and the car is difficult to start;

4) Dirty battery binding posts may also cause poor conductivity, which will affect ignition; Of course, the lack of battery power may also cause a delay in ignition start-up;

5. The viscosity of the engine oil is not suitable: for example, when the temperature is very low, the viscosity of the engine oil is high, resulting in slow oil circulation and dry friction of the machinery, so it is difficult to start, and at the same time, it is very harmful to the car;

7. The carbon canister solenoid valve is faulty: the ignition is weak after exposure, but there is no secondary ignition, generally there is a problem with the carbon canister solenoid valve, because the effect of gasoline transpiration after exposure is particularly large, and the valve of the carbon canister valve is not well sealed, and it is easy to flood the cylinder, that is, the wet wall.
