What is the operation and advantages of some people slamming on the accelerator when they start driving?

As far as I know, there are several situations when starting to step on the accelerator:

1, truck pressure

Many truck hand brakes are air brakes, and all trucks are air brakes. There is a strong spring on the rear wheel brake to keep the brake pad in braking state. When driving, you need to pull the handbrake to inflate it. The compressed air will press the spring to release the brake and the car can go. When the hand brake is needed, deflate, and the spring pushes the brake pad to brake the wheel tightly. Sometimes when the vehicle is parked for a long time, the air pressure is too low to push the spring car and the vehicle cannot start. At this point, the driver needs to step on the accelerator to make the air pump generate enough pressure and release the handbrake. This is why we can see that some big trucks don't step on the accelerator when they start.

2. If you can't shift gears, step on the accelerator and put it in gear.

Old drivers or drivers who are familiar with manual transmission will probably understand this. When driving manual gear, sometimes first gear or reverse gear can't be engaged. At this time, if you can get the car moving or loosen the clutch, you can hang up. This is mainly because the teeth of the first gear combination sleeve and the first gear ring are not aligned when the gears are engaged. Although there are inclined surfaces on the teeth, the transmission oil has high viscosity and resistance when the car is cold, and it is not easy to shift gears. At this time, release the clutch and step on the accelerator, and the gear can be moved. After alignment, the gear can be shifted smoothly.

3. Startup skills

This should be a misunderstanding. When many manual gears start, we stand outside the car. At first, we will feel that the engine is loud, and the sound will be small after the car starts. I feel that the driver deliberately stepped on the accelerator when starting. Actually, that's not the case, because the process from static to moving needs the most power, so you must step on the accelerator first when you start. At this time, the engine speed increased and we heard the roar of the engine. Next, loosen the clutch and load the engine, which will inevitably reduce the speed and sound. However, at this time, the driver did not release the throttle, and the sound we heard was only caused by the reduction of engine speed.

Old driver, really old driver.

For this kind of operation, very experienced drivers will do it, and there are many benefits. Let's talk briefly here.

It is common for some old cars to slam on the accelerator when starting. In the past, there was no synchronizer in the car, and the driving experience was basically poor. Basically, it depends entirely on the driver's driving skills to achieve the smoothness of the car. Booming the throttle, filling the throttle and reducing the throttle at the start are all routine operations to achieve the best synchronization, make the car run more smoothly and make the engine in a relatively strong state, that is, the most powerful.

When shifting gears or starting, first blow the throttle to increase the engine speed, and then shift gears, the power output of the car will be relatively stable, and the engine will be in a high torque state, and there will be no frustration experience caused by low speed. This is especially true for large trucks. Shifting operation and kicking the gas pedal is basically a compulsory course because the car is heavy enough. If you don't have the maximum torque and power, loosen the clutch before giving oil, and the engine will be quite sluggish because it can't be pulled. At this time, if the engine is loaded, it is more difficult to increase the speed again, and the relative fuel consumption will be more.

Therefore, all the people who step on the accelerator are old drivers, which is why the manual gear will have a better start and better fuel consumption performance. There is no such experience for automatic transmission. The sharing of baile fish is over. Welcome to communicate with us.

There are only two questions. First, if you don't give oil when going uphill, you have to increase the throttle, or a novice will increase the throttle if he is afraid that the car will start to stall, so that the car can start more easily.

Another is when waiting for traffic lights side by side, you want to give oil quickly first, so you can cross the intersection faster, and the idle speed is unstable in winter, so it is easy to have problems when starting, so increase the throttle to make the car run quickly and warm up.

Then there are some people who are used to starting with a big throttle, so they can't help but increase the throttle when they start, and some don't know what's going on.

This habit is mainly to fully preheat the piston that has just started running to prevent the chimney from flameout. But don't blow the throttle too hard, so as not to cause mechanical damage to the engine, and carry out appropriate oil supply work. I hope it helps.

In this case, it is usually a manual gear. After all, it can be quickly upgraded to second gear. That's what I am anyway.
