What is the harm of slamming the throttle in neutral at 6000 rpm

Neutral. The hazards of slamming on the throttle at 6000 are: it is easy to cause wear and ablation of the input shaft bearing, synchronous gear and synchronizer, and gearbox.

The abnormal noise. If you step on the accelerator in neutral gear for a long time, it will cause serious insufficient combustion, and if this part of the inadequate combustion oil and gas ignites outside the cylinder, it may cause spontaneous combustion of the vehicle. At the same time, insufficient combustion is more likely to produce carbon deposits.

and clog the three-way catalytic converter.

In turn, the three-way catalytic converter is abnormally high, and the high temperature may lead to spontaneous combustion of the line, and the consequences are more serious.

Mechanically speaking, the neutral gear pedal throttle, although the gear is empty, but the engine's power through the clutch will drive the input shaft of the gearbox will always be in the state of working ** motion) At this time, step on the throttle, the gearbox in addition to the output shaft and the synchronizer of each gear do not rotate, like the input shaft, intermediate shaft (here with a three-shaft gearbox.

Hello, the engine is very worn, can not do this, high-end car maintenance technician Li Zhiwen for your service, I hope mine can help you! [If you have a problem with the car, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Hello, this will bring wear and tear to the engine, [there is a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Hello, this will bring wear and tear to the engine.

: The engine speed of the cold car hitting the accelerator in neutral gear soared to 5 6 thousand, and I stepped on it 5 6 times, so that the car engine was damaged a lot, do I need to repair it?

After starting the car to warm up, listen to the idle speed if there is no abnormal noise, and then increase the throttle slightly if there is no abnormal noise, there is no problem, and there is no need to go to maintenance.

In the future, it should be noted that the idle speed of the cold car is preheated to C. You can't slam the throttle on a cold car!

This will not cause damage to the engine, unless you do it with all the oil dry, and it will cause damage, and this kind of idle 5-6 thousand rpm is not harmful at all.

: Stepping on the accelerator in neutral for a short time has basically no effect on the car and does not hurt the car; However, if you press the gas pedal for a long time, it will be a kind of car destruction.

Step on the accelerator in neutral gear and the water temperature rises quickly. In the case of n gear, the engine is not involved in the drive, but in operation, which is equal to the usual acceleration of driving, the engine speed can reach 3000-4000 rpm, neutral refueling will not aggravate engine wear, belongs to the normal use range, N gear is neutral, if the time is not long, there is nothing to do, the engine speed at this time is about 4,000 to 5,000 rpm, and it will cost oil for a long time, which will cause the water temperature to be too high and cause the pot to boil.

N gear throttle hazardsWhen starting the car, the manufacturer stipulates that the gear can only be in the P gear and N gear, the engine will start, so the gas pedal in the P gear and N gear will not cause damage, in the case of N gear, the engine is not involved in the drive, just in operation, which is equal to the usual acceleration of driving, the engine speed is used to 3000-4000 rpm, and the neutral gear refueling will not aggravate the engine wear, which belongs to the normal use range, if you step on the medium and high speeds, suddenly hang from the N gear into the D gear, which will cause damage to the gearbox.

This is the oil cut-off protection speed set by the manufacturer, which is to prevent the engine speed from rising too high when the accelerator is stepped on empty.

Even without this protection, if the rev speed rises to the red line area, the oil will be cut off, and the engine speed cannot be higher. The protection of the red line area is also effective when driving in low gears, such as first gear, when you step on the speed of the red line area when accelerating sharply, there will also be a maximum speed, which will not be higher.

If there is no oil cut-off protection, the speed of the engine can indeed exceed 10000 rpm, and now the engine used in the car, the maximum power speed is basically between 5500-6500rpm, beyond this speed, the wear of the engine friction pair will indeed increase sharply.

Because in N gear, the engine is not combined with the gearbox, and the engine is not conformed, so the on-board computer will control the speed of the engine, if the speed is not controlled, the engine speed is too high, which will cause the wear of the components inside the engine to accelerate. So that's how the vehicle computer is set up. However, if there is an abnormal noise in the engine, which is not a normal working sound, then you need to check it as soon as possible.

Engine idling protection can only show that the manufacturer of your car is more careful, don't worry, now the protection system of 100,000 and above cars is better, don't worry about anything when driving!

OK. Hanging the throttle in neutral gear for a long time will cause insufficient gasoline combustion, and insufficient gasoline combustion will form carbon deposits, which will adhere to all corners of the engine and block the three-way catalytic converter, resulting in the temperature of the three-way catalytic converter is too high, once the temperature is too high for a long time, it is easy to lead to spontaneous combustion of the line, and finally the combustion spreads to the whole car, resulting in the scrapping of the car.

Moreover, once the carbon deposition is too much, it will also lead to engine idle shake and engine power attenuation, which will reduce the acceleration performance and increase fuel consumption. If a part of the gasoline that is not fully burned ignites outside the cylinder, it will also cause the vehicle to spontaneously combust, resulting in the destruction of the car and the death of people, so the harm of hitting the accelerator in neutral gear is far more serious than imagined.

It is possible to reach 5000 revolutions within 10 seconds.

If it takes a long time, it will accelerate the wear and tear of the internal parts of the engine.

The engine runs at high speed for a long time in neutral, the internal heat can not be dissipated in time, the oil will accelerate aging and fail at high temperatures, and the consequences of high-speed operation when the parts lack lubrication can be imagined.

Pacific Automobile Network] has little impact in the short term, but do not take too long, especially during the run-in period, which will increase engine wear. Most cars have engine protections that limit the engine's revs in neutral.

Neutralgear refers to the state in which the motor vehicle gear lever is not put into any forward or reverse gear, and the gearbox is completely separated from the engine. The neutral of the manual transmission is in the middle position, while the neutral of the automatic transmission is"n"Signs. The essence of neutral gear is to cut the connection between the differential and the gearbox, so that the tires can move freely and will not be affected by the engine.

The neutral gear of the manual transmission car replaces the action of pressing the clutch all the time, which is commonly used when stopping for a short time to prevent the car from turning off. For automatic models, the biggest use of neutral is that it allows you to push the car away or tow it away if you lose power.

Throttle, also known as"Dampers"，"Throttle"。Refers to a control device that controls the power (thrust) of an engine. In piston aero engines, the throttle controls the throttle opening of the carburetor to control the amount of cylinder filling, which determines the engine's power output.

On gas turbine engines, the throttle controls the metered fuel flow at the fuel regulator, which determines the thrust generated by the engine. The throttle position is controlled by the driver in the cockpit to the accelerator lever, and the control system components such as tie rods, rocker arms, torsion tubes, steel cables, pulleys, and fan wheels are transmitted to the carburetor or fuel regulator on the engine for control.
