Why sometimes it takes two times to start the car with the key

There are several reasons for the ignition start of the car, if the new car is basically a successful start, other situations are the time to maintain, the throttle is dirty, you can ignite sometimes the start is not successful, in addition to whether there is a problem with the starting motor, whether the battery is short of power, whether there are too many additional electronic devices. If the above parts are problematic and aging, it is generally not so smooth to start the car.

In addition, the normal process of starting and turning off the car key is to turn off the air conditioner, audio and video as much as possible before turning off the engine. Pull the handbrake, extinguish the fire, if the air conditioner does not care about the sound and video, the load on starting the car is too large, and it will also affect the ignition.

When starting, the key is twisted once, and after all the detection indicators are lit and then extinguished, the ignition is started. In this way, the ignition is done after the normal inspection of each part. Starting the car will also be smooth, I hope it can help you.

There are many places on the Internet about automatic transmission, and manual transmission ignition and driving methods

This means that there is something wrong with your car igniter, and it is recommended that you go to the car dealer to let the master check it!!

It depends on what the situation is when you start, and it depends on what model you are, I drive a Roewe 550 car, and I sometimes send it twice or more times It is not a mechanical problem at all, it is a problem with the key itself.

First time: Lighting the fire. The second time: start the car.

Common points of failure for start-up difficulties are:

1. The car is parked for a long time.

The use time of the car battery is the main reason for the loss of electricity, usually the service life of the car battery is two to three years, if it exceeds this year, once the car is stopped for two or three days, it is very easy to lose power, resulting in weak start.

2. Forget to turn off the lights and on-board electrical appliances.

When parking and turning off the engine, forget to turn off the lights in the car, the battery may be low after a night of consumption, resulting in weak starting.

3. Forget to turn off the air conditioner before turning off the fire.

Most car owners are accustomed to not turning off the air conditioner or letting the air conditioner start automatically with the vehicle starting, which will cause the air conditioning system to automatically start working after each time the ignition switch of the vehicle is turned on, the consequence is to directly lead to the instantaneous power load of the vehicle is too high, and the battery will be lost for a long time.

4. The starter motor is damaged.

The carbon brush inside the starting motor is worn, resulting in insufficient speed of the starting motor, and the flywheel that drives the engine to rotate is more difficult, so there will be a failure phenomenon of weak starting.

The car key is opened twice means that the double safety lock (also known as the anti-theft security lock) function, and the factory default is on.

This function is to press the key fob unlock button once to open the driver's door lock, and press the key fob unlock button twice to open all the doors, and its purpose is mainly used to prevent theft and robbery (especially for single female drivers).

1. Poor contact with the ignition switch of the training shirt. Replace the ignition switch.

2. The positive and negative wires of the battery are oxidized or have poor contact. Clean up the oxide (after rinsing with boiling water, rinse the thread and polish it with sandpaper), and tighten the positive and negative pole wire branches.

3. The starter bearing lacks oil and cavity, and the rotational resistance is too large. Remove the starter, disassemble it, clean the dust inside, and fill the bearings and moving fittings with oil.

Seconds after pressing the button, the vehicle completes the circuit self-test.

After pressing for 1 second, the circuit of the engine motor is turned on, the motor is working at high speed, the motor rotor is moving at the flywheel of the motor engine, and the car engine is started in a roar.

What is the control of the accelerator pedal pressed at the moment.

The accelerator pedal controls the opening and closing of the engine's intake valves, also known as throttle valves. The deeper the throttle is pressed, the larger the intake valve opening and closing viewpoint and the greater the air intake.

The spark plug is then incinerated to ignite the combustible gas to form a "deflagration", and the infinite impact force causes the piston to move. Such a "deflagration" occurs hundreds or thousands of times per minute. The movement of the piston moves the engine crankshaft and rotates rapidly.

Engine speed is the number of revolutions of the crankshaft per minute.

The cylinder piston reciprocates under the propulsion of the shut-off deflagration, and a succession of power occurs.

At this point, the engine has successfully finished starting, hanging the gear and stepping on the accelerator, the speed and speed of the vehicle have gradually climbed, and we can go!
