The harm of sudden braking and suffocation to the vehicle

There is definitely an impact, but it is not a big problem, because the current car gearbox has a synchronizer, so no matter the high-speed and low-speed shifting, it can smoothly enter the gear, because the synchronizer exists! When you brake, the engine speed must be from high to low speed, at this time the gearbox gear and the engine speed are synchronized, so you don't have to care about the gearbox has something to affect, the engine, it has little impact, because the sudden high speed, or sudden low speed start is very normal, just like you drive the key, the engine suddenly runs from stationary to thousands of revolutions, isn't it that the ignition of the car also has an impact on the engine! So no more than worrying.

You must know that the way to reduce the speed of the car in the downhill emergency is to enter the gear, use the clutch brake, that will be more affected than the brake engine like you, even if this has to be included in the car driving manual, how much impact do you feel on the car?

The hazard of sudden braking and stalling has nothing to do with the gearbox synchronizer, the gearbox synchronizer only synchronizes the speed of different gears when changing gears, so as not to cause damage to the gears of different gears. The speed of the car deceleration engine from high to low speed is because the number of wheel revolutions and the engine speed are proportional in the same gear, please note that what you say "the transmission gear and engine speed are synchronized at this time" has nothing to do with the transmission synchronizer we said.

Frequent suffocation will cause the number of charging and discharging of the battery to increase, and the service life of multiple batteries will cause a certain abnormal noise; In addition, it will cause poor combustion and easy to form carbon deposits.

With the development and progress of technology, today's car engines are relatively durable, so there is no need to make a fuss about the occasional suffocation, it doesn't matter. As long as it doesn't sit out all day like the rainy autumn weather, it is okay to continuously extinguish the fire.

1. If there is damage, the impact on the engine is mainly concentrated in the part of the mechanical work, and the recoil force will be generated when the flame is stalled, and if it is too frequent, it may cause damage to the relatively fragile parts such as camshaft and piston crank. The damage to the transmission system is relatively fast, such as the wear of the cross joints and the increase in the open space of the transmission shaft.

2. The automatic liquid stop and backup models will not easily stall, while the manual models may often stall due to the low driving level. However, it is not excluded that the automatic transmission will not stall the car, and the main reason is that the engine stalls due to carbon accumulation due to the use of inferior fuel (many gas stations sell impure oil for profit).

Car owners need to park the vehicle before turning off the vehicle, some car owners are worried about a question, what will happen to the brakes, so what is the harm of turning off the brakes?

When the vehicle is turned off, the owner steps on the brake pedal of the vehicle at the same time, there is no harm to the vehicle, if the owner steps on the brake pedal of the vehicle after the vehicle is turned off, the negative pressure inside the vehicle brake pump will be released, the next time the owner uses the car, when starting the vehicle, the brake pedal of the vehicle will be significantly stiffened, and it is difficult for the owner to step on.

Car owners need to pay attention to the following when turning off the vehicle:

1. When the owner of the car sales company turns off the automatic transmission vehicle, he needs to step on the brake pedal of the vehicle first, hang the gear of the vehicle to N gear, and then pull up the handbrake function of the vehicle, and then release the brake pedal of the vehicle, and hang the gear of the vehicle to the position of P gear with loss, and then turn off the vehicle.

2. When the manual transmission vehicle is turned off, it is necessary to step on the clutch pedal of the vehicle at the same time, hang the gear of the vehicle to the empty cong gear, and then pull up the handbrake function of the vehicle to turn off the vehicle.

If it is an automatic car, it may be that the car idle stability valve is damaged, which directly causes the idle speed to be controlled by the control valve and cannot maintain normal work. The reason for the brake stall is due to the fact that the engine and transmission are not separated in time due to the brakes being too strong.

The car stops when it slows down when it hits the brakes, mainly because the gear is too high, the brake is sudden or the brake is only stepped on, and the clutch is not pressed. Therefore, if the gear is high, the gear should be reduced in time; If the speed is not fast, the clutch should be applied first, and then the brake should be applied gently, and when a pedestrian or non-motorized vehicle is moving forward, it is not necessary to fully press and stop.

Generally speaking, in urban road conditions, emergency braking should be avoided as much as possible. Emergency braking not only increases fuel consumption, but also affects the service life of the tires. At the same time, when passing through ramps such as bridge decks, pay attention to long-distance braking when going downhill, do not hang into neutral gear, and be sure to slide with gear.

Otherwise, the braking distance will be extended, the braking effect will be affected, and it will also be detrimental to safety.

In snow and ice conditions, do not use emergency braking. You can get into low gear, release the throttle, and brake with the traction of the engine. In order to increase the friction coefficient of the road surface, snow chains can be hung; If it's grass, it's not as slippery as ice and snow, so in general, it's enough to run at a suitable speed.

If you need to brake, you should have foresight and judgment to prevent you from encountering obstacles or falling into soft mud.

What are the hazards of stepping on the brakes when the car is turned off There are the following hazards when the car is turned off and stepping on the brakes: 1. Most of the brakes of the car are vacuum assisted, and when you open the engine cover, you will find that there is a drum-shaped device where the brake pedal is opposed, that is, the vacuum booster pump; 2. There is a pipe containing a one-way device to connect the booster pump to the intake divergent rent of the engine, and use the suction generated by the engine intake pipe to make the booster pump generate negative pressure. 3. After the ignition is turned off, the negative pressure will not continue to be generated, and the remaining negative pressure will be released after two brakes, and it will be more difficult to step on the pedal. @2019
