What happens to the manual transmission car stepping on the clutch and automatic refueling, is there

When you press the clutch in gear, the engine speed will automatically increase, and it is most noticeable in low gear.

In this case, it is generally that the throttle and idle motor are dirty, and it is enough to clean them.

Reason: When the vehicle is in gear, the engine needs to output a large load, at this time, when you step on the clutch, the engine output load suddenly decreases, but due to the dirt caused by the throttle and the idle motor, it cannot respond in time and return to the correct idle throttle opening position, so the engine speed will automatically increase at this time.

Special note: The throttle can be cleaned with a carburetor cleaner, but it is best to wipe the idle motor without getting a corrosive carburetor cleaner. The idle motor is a very delicate element, and once its sealing belt is broken, it may cause unstable or increased idle speed, resulting in fuel consumption of the vehicle.

The engine in the driving state does not need as much power as idling.

Clutch. The active part and the driven part use the friction between the contact surfaces, or use the liquid as the transmission medium (hydraulic coupling, or use the magnetic transmission (electromagnetic clutch) to transmit torque, so that the two can be temporarily separated, and can be gradually engaged, and the two parts are allowed to rotate each other during the transmission process. The torque emitted by the engine is transmitted to the driven disc through the friction of the contact surface between the flywheel and the pressure plate and the disc disc on the disc plate.

When the driver steps on the clutch pedal, through the transmission of the parts, the large end of the diaphragm spring drives the pressure plate to move back, the driven part is separated from the active part at this time, and the transmission device of the engine at different speeds should transmit different speeds to the wheels, and at this time it is necessary to separate the slow gear from the wheel, and engage the wheel with the high-speed gear, and the clutch will be used in this part.

Yes

You can do this, but it's best to wait until the clutch is pressed before changing gears. If the clutch is not fully stepped on, it is easy to cause damage to the clutch, and the key to the start of the manual transmission car is the cooperation between the accelerator and the clutch.

The operation of shifting gears is: wait until the speed of the engine increases, while pressing the clutch with the left foot, release the throttle with the right foot, and the clutch is stepped on to the end, and start to shift gears. Then release the clutch with your left foot while slowly pressing the accelerator with your right foot.

The coordination of the clutch and throttle when shifting gears

First of all, you must put the gear in the neutral position, and press the clutch to the end after starting the car.

Then put the gear into the position of 1st gear, and then release the clutch, and release the clutch slowly.

Refueling when shifting gears, also known as blast oil, is not needed when adding gears, the speed reaches about 2000, and the speed does not reach the speed adapted to the gear, it is useless, and is generally used when the vehicle is reduced to a low speed gear when running at high speed.

There are often cars waiting for a red light to be in neutral.

Step on the accelerator first There is a booming sound.

If you change the first gear, there is already oil working in it.

Faster start-up acceleration can be obtained.

But it's more fuel-intensive.

。。。If you don't understand, don't talk nonsense. Stepping on the clutch and then stepping on the throttle is to spray empty oil, which may cause the fuel nozzle to be blocked, if you want to control the speed, you can just go deeper.

There is no damage except for the cost of oil.

It depends on whether your engine is low or high.

Second, the correct way:

1. After starting the car, press the clutch pedal, hang up the gear, and release the hand brake.

2. At this time, add a little throttle, slowly release the clutch, the operation essentials are: slowly release the clutch with the left foot and gradually step on the accelerator with the right foot. When you hear (mainly feel) a drop in engine rpm, gradually increase the throttle while continuing to loosen the clutch.

3. After the clutch is fully released, keep the throttle unchanged.

4. After the speed of the car is up, you can feel that the engine speed increases, and when there is a surplus, you can start to shift gears.

5. The gear shift operation is: the engine speed goes up, while the left foot steps on the clutch, the right foot releases the throttle, and the clutch is stepped on to the end, and the gear shift begins. Hook up the gear, slowly release the clutch with your left foot, and gradually refuel with your right foot.

Under normal circumstances, when changing gears, the clutch is pressed at the same time.

And loosen the throttle, the engine speed also begins to drop at the moment when the power is cut off, if the throttle is loosened and disturbs the beam early, the engine speed drops first, which may cause engine braking.

Causing a crash in the car, it feels like suddenly hitting the brakes. If the throttle is loosened late, the clutch is already disengaged, and pressing the throttle when the engine is not under load will definitely lead to an increase in rpm.

2. Idle driving.

The common situation is this: traffic jam, the first gear does not step on the accelerator and advances by idling, at this time the throttle.

The ECU controls the engine operation at idle speed and controls the rpm at the target idle speed. Since the vehicle is driving, the idle speed will be slightly higher, which is the idle speed compensation function of the ECU. When you step on the clutch, the engine unloads the load, and the running resistance is instantly reduced, so the engine slows down and the code force increases, and the speed increases.

It's like if you're pulling an object forward with a rope, and you rush forward after suddenly cutting the rope. When the rpm speed rises and the target idle speed is exceeded, the ECU will intervene to restore the idle speed to the target idle speed under the current operating conditions.

The clutch is a tool that connects or separates the motor and the transmission part of the car, and after the clutch is released, the engine does not exert force on the car itself, and the engine speed suddenly increases!

You mean that when you press the clutch, the gauge on the right side of the dashboard will go up? That's the clutch tachometer, and if the rpm increases, your previous speed is basically the idle speed, the punch and the rpm. The east air on the car is not much more west?

Don't be nervous, it's normal. It is recommended that you upshift at 2000 rpm. Less than 1000 rpm minus bucket Na.

The reason for the sudden increase in the speed of the clutch is that after stepping on the clutch, in order to ensure that the engine does not turn off, the computer automatically gives the throttle. This is a normal phenomenon.

Yes. If Lu Tease is holding the car that sells dynamic gears early, it must step on the clutch when it grows, because in this way it can sensitize and protect the engine and avoid engine damage or failure.

You will step on the clutch because you can slow down the speed at this time. It will not cause traffic accidents. It is very safe.

Yes. Because after stepping on the clutch, you can better gear and reduce the damage to the car, most people will do this.

There is no need to press the clutch for an automatic transmission, because there is no clutch pedal on the automatic transmission car. The switching between gears is completely controlled by the trip computer. The so-called automatic transmission, to put it simply, means that the owner does not need to change the gear manually, and the vehicle will automatically change to the appropriate gear according to the speed of driving and traffic conditions.

The specific steps of automatic gear ignition are: first put the gear in the position of N gear or P gear, and then the key needs to be pulled to the ON position, about 10 seconds or so, when the self-test is normal, you can start the ignition normally. If the rpm drops below 1000, it means that you can idle and drive normally after slowly heating up.

At present, there are only two pedals for automatic transmission, brake and accelerator, and if there is a third pedal on the left, it is a foot-pedal handbrake, or it is used to put the foot. Generally, the gearbox of automatic transmission car has , P, R, N, D these gears, where P is the parking gear, R is the reverse gear, N is the neutral gear, and D is the forward gear.

Automatic mega shifts do not require the clutch to be pressed when changing gears. Because automatic transmission cars do not have a clutch, there is no need to step on the clutch.

The correct way to shift gears:

When the P gear catches fire, apply the brakes first, and then push the gear lever into the target gear. If the brake gear is not pressed, the gear lever will not be pushed because the gearbox is equipped with a safety locking mechanism.

Gear shift precautions:

If the vehicle enters D or R from N, it must also be asked to apply the brakes. At this point, the vehicle moves from a stationary state to a state of motion. If the brakes are not applied, the car will rush forward (backward) violently, causing a safety accident and causing great damage to the vehicle's transmission.

When driving, you don't need to apply the brakes to enter the sport mode from D, and you don't need to enter the manual mode. When entering P from N after stopping, you must step on the brake, otherwise you will not be able to push it up (safety locking mechanism).

Manual shifting: The car with manual transmission must step on the clutch, and it must be pedaled all the time. If you don't step on the bottom, the car will make an abnormal noise, and even the clutch will shake.

The owner should step on the clutch scientifically when changing gears. The most important technical indicators and skills to ensure the smooth shift of the transmission are: to ensure that the two gear shifting gears are synchronized, and the gear sleeve can be smoothly set on the two transmission gears at the moment of synchronization.

Millions of car purchase subsidies.

1.After the clutch fails, you should not start the car in a hurry, but check whether there is any problem in other places, whether the oil is normal, and whether the brake and accelerator are used normally. Look at everything that can be inspected under the front cover.

2.Since the pickup truck itself has been driven for 4 years, and the special structure of the diesel car, the repair shop said that it can start without a clutch. After hanging the first gear, I released the handbrake, and then the ignition, and the vehicle drove away after a few breaks.

3.When driving on the road, you should pay special attention, you must slow down, there is no clutch, the vehicle will be very aggressive when changing gears, especially when changing second and third gears, try to add a foot of throttle and then shift gears.

4.If you want to downshift, add the throttle a little bit as well, and guess that if the rock is really not good to reduce, just put it into neutral and then hang it up again. When encountering a traffic light, keep a long distance from the vehicle in front to avoid the danger of starting and running.

5.It should be noted that the diesel pickup can be so hard to drive, and it is not a new car, if the owner does not want to take the risk in the case of clutch failure, it is best to ask for a tow truck to avoid hard gear is not good for the vehicle.
