Sitting in the car, the car ignition throttle starting, this is our usual how commonplace things. But how does the automobile engine start from stationary to running? I'm afraid many people don't know much about it.

The following dynamic, detailing the car from the static to the start of the process, intuitive and obvious, after watching will make you more understanding of the car!
What happens to the car when you press the start button?

0.5 seconds after pressing the button, the vehicle completes the circuit self check

one second After pressing, the circuit of the starter motor is switched on, the motor is driven at high speed, the motor rotor drives the engine flywheel to move, and the automobile engine starts in a roar.

What does the accelerator pedal control at this time?

The accelerator pedal controls the opening and closing angle of the engine intake valve (also called the valve). The deeper the gas pedal, the greater the angle of opening and closing of the intake valve, the greater the intake.

After the engine starts, the engine oil is pumped into the lubricating area (the orange area), and as the intake valve opens and opens, the air enters the cylinder.

In the direct injection engine, the air enters the cylinder while the gasoline is injected into the cylinder through the high-pressure nozzle and mixed with the air to form a combustible gas.

Then, the spark plug fires at the right time, igniting the gas to form a ""deflagration"", and the huge impact force causes the piston to move. Such a ""deflagration"" occurs hundreds of thousands of times per minute. The motion of the piston causes the engine crankshaft to rotate at full speed. The speed at which the engine rotates is the number of turns in the crankshaft every minute.

The cylinder piston moves back and forth under closed detonation to generate continuous power.

So far, the engine successfully completed, put up gear, step on the gas, the speed and speed rise gradually, we can set off!
