The sound of a car starting a fire like a big gasp?

1. The relative sound of the cold car and high idle speed is louder, and then there is the compressed sound of the secondary air pump. All in all, it feels like it's louder. 2. If the ignition sound is the most sexual, or the ignition is turned off after the ignition, it is recommended to go to the maintenance shop to check the spark plug, and at the same time, dredge the automobile oil pipeline.

If you start cold, the engine sound is loud, and after a minute it tends to be quiet, and when you start hot, the sound is very quiet, which is normal.

Because when stopped, the oil in the engine automatically flows back into the oil pan. The next day, when you start cold, the oil will slowly return from the oil pan back to the cylinder head. If it's a hot start, the oil in the engine is already in place, lubricated and sealed well, and the sound will naturally be quiet.

So, the cold start will be louder, but it won't last long, up to 2 minutes. If the engine has a prolonged roar, it should be checked at the workshop as soon as possible.

If the engine is loud and creaks during a cold start, then check the oil usage, if you use poor quality gasoline, it will also cause the engine power to decrease, resulting in increased carbon deposits inside the engine and increased engine noise.

The oil is not in place yet, and the hot car is fine.

Summary. After the car is on fire, what is the feeling that the engine has a gasp when idling.

Hello, started the idle panting, this is caused by the engine not working well, you need to check whether it is caused by more carbon accumulation on the throttle, and the spark plug gap is large, the ignition coil is damaged, or the intake pipe has a leak, it is to find a repair shop to check the above items can solve the problem, I hope mine is helpful to you.

Hello dear! First of all, this kind of old car has this situation, and there will be more possibilities involved, and it is necessary to return to the cluster one by one from many aspects to investigate the causes. Check whether the valve clearance is too small or the closure is not strict due to carbon deposits, wear and tear, etc., whether the cylinder pressure is low, whether the spark plug is bad, whether there is a slight air leakage in the intake pipe and other hoses related to the engine, carburetor and secondary leakage Bu Sakura intake system, whether the carburetor electronic control damper is not working, mixing ratio, oil level, oil needle, etc.

You are welcome to consult us again.

When the vehicle starts cold, the owner needs to warm up the vehicle, and the engine temperature is increased before the vehicle can be used.

1. It may be that there is too much carbon deposition at the spark plug and ignition coil of the vehicle, which affects the normal operation of the vehicle's idle motor and makes the vehicle gasp when the vehicle starts cool.

2. It is also possible that the fuel label of the vehicle is too low, such as the vehicle needs to fill 95 gasoline, and the owner mistakenly adds 92 gasoline, and the owner starts the car cold, like a big gasp, and even stalls.

3. If the service life of the vehicle is too long, the throttle clearance of the vehicle is too small, or the throttle is not closed strictly due to serious wear, the pressure of the engine cylinder will be low, and the vehicle will gasp and stall when the cool car starts.

When the owner uses the vehicle, if the vehicle starts cold, and the vehicle is panting, it is necessary to go to the auto repair shop for maintenance in time to ensure that the vehicle can be used normally.

It is normal for this situation to occur when the engine temperature is relatively low, lubrication and combustion are not very good, so the engine will have this situation, and the noise of the engine at this time is relatively large, and the smell of exhaust is relatively large, which is normal.

After the cold start, the temperature of the engine is relatively low, at this time the ECU will increase the amount of fuel injection, and the concentration of mixture in the engine is relatively high, so that the engine can reach the normal working temperature as soon as possible.

And after the cold start, the oil has not reached the normal working temperature, and the lubrication of the engine is not good at this time.

When the oil does not reach the normal operating temperature, the viscosity of the oil is relatively high, and the oil cannot bring sufficient lubrication to the engine.

Some riders have the habit of heating up the car, and it is a good habit to warm the car, but many people have the wrong way to heat the car.

Most riders will heat up the car in situ, but in fact, this way of heating up the car is wrong.

The normal way to warm up is to start the engine and then put it in gear, but don't let the engine run at too high rpm when you first start driving.

This increases the load on the engine, which can speed up the heating up of the engine.

And when driving in gear, you can also let the transmission differential and other components run, so that the gearbox and differential can also quickly reach the normal working temperature.

It is recommended that you do not idle the car in place.

The engine is loud when the car starts cold.

This happens because the oil has not sufficiently lubricated the engine, and the noise will decrease after a while of engine operation. Engine oil is very important for the engine of a car, engine oil is called the blood of the engine, if there is no oil in the engine, the engine cannot function properly.

Engine oil not only plays a lubricating role in the engine, but also plays a role in cleaning, sealing, buffering, rust prevention, and heat dissipation.

When the engine is running, the oil forms a film between the various parts in the engine, which prevents friction caused by direct contact between the various parts in the engine.

If the various parts within the engine are in direct contact and cause friction, it will exacerbate the wear and tear of the engine, and it will also cause the engine to overheat.

If the engine continues to run in an overheated state, it can cause serious damage to the engine.

The performance of the engine oil will be reduced after a long period of use, so the engine oil needs to be changed regularly.

If it is not replaced for a long time, it will also exacerbate the wear and tear of the engine.

When using the car, you must change the oil regularly, and change the oil filter element together every time you change the oil.

The oil filter is used to filter the oil, and if there is no oil filter, the oil will become dirty after a period of use.

When buying engine oil and oil filter cartridges, be sure to choose the best products from big brands, and be sure to buy them from regular channels. (Photo by Q&A: Q&A called the beast) @2019

This may be that the pressure of the electronically controlled injection system of the fuel is low at start-up, which affects the fuel supply, and after the normal operation of the engine, the pressure is normal. This usually happens occasionally, but if it happens frequently, you need to go to the repair shop to check whether the fuel system and filters are blocked.

Fuel filter clogging symptoms, gasoline pump filter clogging, gasoline filter clogging and fuel injector clogging to varying degrees can also cause insufficient fuel supply. In addition, the filter on the fuel pressure regulator is clogged, resulting in poor oil return, which can cause the fuel system pressure to be too high, resulting in an over-concentrated mixture.

Over-dilute and over-concentrated mixtures can lead to under-power in the engine, which can lead to car towering. If the mixture is too thin, if the round crack is not felt on the flat road or the degree is light, and it is obvious or heavy when going uphill, it can be judged to be caused by the mixture too thin. If the mixture is too thick, if the acceleration is slow when driving and refueling, and when it is serious, it feels strong when the car is refueled, and the driving feels strong after refueling, this phenomenon is generally caused by the mixture being too thick.

It may be that the electronically controlled fuel injection system is at a lower pressure at start-up, affecting the fuel**. After the engine is running normally, it is fine that the pressure is normal. This usually happens by accident. If it happens frequently, you need to go to the repair shop to check whether the fuel system and filters are clogged.

Symptoms such as clogged fuel filters, clogged gasoline pump screens, clogged gasoline filters, and clogged injectors to varying degrees can also cause insufficient fuel supply. In addition, the filter on the fuel pressure regulator was clogged, resulting in poor oil return, which could cause the fuel system pressure to be too high, resulting in an over-concentrated mixture.

Too thin and too thick of the mixture can lead to a lack of engine power, which in turn can lead to a bumpy car. The mixture is too thin. If the bump is not felt or slightly felt on the level road, and it is clearly felt or severely felt on the uphill road while driving, it can be judged that the mixture is too thin.

If the gas mixture is too thick, you will feel that the acceleration is slow when refueling, and when it is severe, you will shrug your shoulders, and then you will feel very powerful when you refuel. This phenomenon is generally caused by the overconcentration of the gas mixture.

This is normal. When the engine temperature is low, the lubrication and combustion are not very good, so this happens to the engine. At this time, the noise of the engine is relatively loud, and the smell of exhaust is relatively strong, which is normal.

After a cold start, the temperature of the engine is comparatively lower. At this point, the ECU will increase the amount of fuel injected. At this time, the concentration of air-fuel mixture in the engine is relatively high, so that the engine can reach the normal working temperature as soon as possible.

Moreover, the oil has not reached the normal working temperature after the cold start, and the lubrication of the engine is not good at this time.

When the oil does not reach the normal operating temperature, the viscosity of the oil is relatively high, and the oil cannot bring sufficient lubrication to the engine.

Some riders have the habit of warming up their cars, which is a good habit, but many people do it wrongly.

Most drivers will warm up their cars in the same place. In fact, this way of warming the car is wrong.

The normal way to warm up a car is to start the engine and then shift into gear, but don't let the engine speed go too high at the beginning of the drive.

This increases the load on the engine, which accelerates the temperature rise of the engine.

In addition, when driving in gear, the transmission differential and other components can also be operated, so that the transmission and differential can quickly reach the normal working temperature.

It is recommended that you do not leave the hot car idle.
