There are two ways to start a car, and what are the ways to start a car

In this V-T diagram, the blue line is the speed of uniform acceleration and the red line is the speed of the rated power.

Because p=fv, when p is constant, the velocity is getting bigger and bigger, and f and acceleration a are getting smaller and smaller, so its velocity is like a red line, although it keeps rising, it rises more and more slowly, and then reaches VO.

A certain speed is easy to understand, right?

Then the average velocity is the displacement s t, t is certain, it depends on which displacement Daluo. Obviously, the displacement of p is more than the yellow part of a.

If you can understand what I'm saying, I'll choose it.

As for text-only and formula explanations, no.

I haven't done these questions for a long time, I don't know if it's right, hehehe).

1.Constant power start.

p is constant, and according to p = fv, f = f (traction) - f (friction), the velocity becomes larger and f becomes smaller.

So, the acceleration a becomes smaller.

It starts as a period of acceleration with decreasing acceleration.

Then when f=f, the velocity is maximum, a is equal to zero, and the motion is uniform.

2.Constant acceleration start (constant traction. )

f constant, according to p = fv

So, as the velocity increases, so does p.

This segment is a uniform acceleration motion.

Then, p reaches the power rating.

According to p amount = fv

The velocity continues to increase and f decreases.

a decreased. So this segment is an accelerated motion with less and less acceleration.

Note: Therefore, the maximum speed of constant acceleration start-up is not when the rated power is reached. Then f=f, and the locomotive begins to move at a constant speed.

There are two ways to start the car, one is keyless one-button start; One is to turn the key to start. The function of the one-key start intelligent system is: automatic unlocking.

Automatic locking. Automatically close the window. Automatic anti-theft.

One-click start. One-key power off. Automatic locking before driving.

Automatic unlocking when parking and turning off the engine Zen God change. He also has a function of opening the back box; The key turn start is a mechanical start.

The following are the following ways to use one-button start and precautions

2. The engine needs a large current to start, so the power of the rest of the equipment will be cut off when starting;

3. Turn on and off the power, if you just turn on the power, operation steps: start: press the ignition switch directly, no need to press the brake pedal; Off: Press the ignition switch again.

1. One is the more common key start of Kuansun, that is, the car key is inserted into the keyhole and ignited.

2. The other is the car intelligent Shenxian chain one-button start keyless system, referred to as one-button start, which is the most popular car Paizhou anti-theft and navigation device on the market, with both intelligent induction door opening function and one-button button start engine function.

Steps to start your car correctly:1. After getting into the car, adjust the seat to suit you, and then fasten your seat belt. 2. Start the car, then press the clutch with your left foot and hang up the first gear.

3. Turn the left turn signal and honk the horn to signal. 4. Step on the accelerator with your right foot, slowly lift the clutch with your left foot, stabilize the steering wheel with your left hand, and hold the front end of the manual brake with your right hand; Wait to hear the throttle sound by"Expensive"Shift to"Calm", quickly lower the hand brake.

After the engine starts and runs normally, after confirming that there is no obstacle around the car and has all the conditions for the car to start, press the clutch pedal to the end with your left foot to completely disengage the clutch. If the clutch pedal is not pressed to the end, the clutch can not be completely separated, and the power output of the engine is semi-linked with the transmission.

Put the transmission shift lever into gear, and if the first shift is not smooth, pull the shift lever back into neutral and then make a second shift until it is successfully completed. The gear shift action is required to be accurate and fast, and the position of each gear of the transmission must be clearly identified to prevent unnecessary losses caused by hanging the wrong gear.

Before the car starts, be sure to observe the surrounding conditions to further determine whether it is safe. The front of the car can be observed from the front window, which is clear at a glance, and the side and rear of the car can be observed through the rearview mirror, or the window glass can be lowered to stick your head out of the window.

After the car starts smoothly, the left foot should be moved down from the clutch pedal, so that the clutch pedal is completely relaxed, do not idle the foot on the clutch pedal, because the left foot sometimes involuntarily slightly downward force, it is easy to cause the clutch semi-linkage, in the long run, quickly wear out the clutch friction plate.

The correct steps to start the vehicle are as follows:1. After getting into the car, the seat is adjusted to fit the owner's own position, and then fasten the seat belt;

2. After starting the car, step on the clutch with your left foot and hang up the first gear;

3. Turn the left turn signal and honk the horn to signal.

4. Step on the accelerator with your right foot, slowly lift the clutch with your left foot, stabilize the steering wheel with your left hand, hold the front end of the manual brake with your right hand, and quickly put down the manual brake when you hear the sound of the accelerator change from high to calm. After the engine starts and runs normally, after confirming that there is no obstacle around the car and has all the conditions for the car to start, press the clutch pedal to the end with your left foot to completely disengage the clutch, and then drive the motor vehicle and then go on the road.

The correct steps to start your car are as follows:

1. Observe the surrounding environment of the car

Before driving, go around the car to see if there are obstacles in the tires and chassis, and whether there are children in the driving track.

If there is a vehicle passing at the back of the road, make sure it is correct and get on the bus.

2. Adjust the position

The distance between the front and back, the manual gear mainly adjusts the left foot, and after the ball of the foot steps on the clutch to the end, the foot has a slight margin. Automatic throttle adjustment. If the feet are adjusted, the hands will generally not have much problem, and the hands will be convenient to operate the steering wheel.

The backrest is based on comfort, and everyone's requirements are different, but from a safety point of view, try not to put it too low, driving while lying down will affect the function of the seat belt.

3. Prepare for the fire

Manually shake the stick left and right to see if it is already in gear. The automatic gear observes the gear situation and marks it very clearly. For the sake of insurance, you should develop the habit of stepping on the clutch and braking in the manual gear, even if the car is in gear, there will be no problem in starting it.

Automatic transmission applies the brakes. That's why you can change your seat first and then light the lighter.

China's latest national standard "Terms and Definitions of Automobile and Trailer Types" (GB T 3730 1-2001) has the following definition of automobiles: non-track vehicles driven by power and with 4 or more wheels, mainly used for: carrying people and (or) goods; towing vehicles carrying people and/or goods; Special Purpose.

From July 1, 2018, China reduced import tariffs on complete vehicles and parts.
