What does it mean to start the engine?

[DeNora]

Starting the engine means turning on the engine. Here is a detailed introduction to the engine: 1. Principle: The cylinder injects gasoline and air through the intake hole and fuel injection hole, which are fully mixed inside the cylinder. When the spark plug ignites the mixture, the mixture explodes and burns violently, pushing the piston downward and generating power. At the same time, the enormous pressure from the explosion also pushes open the exhaust hole of the one-way valve, expelling the exhaust gas. Subsequently, the residual exhaust gas in the cylinder gradually cools, the pressure decreases, and the external atmospheric pressure pushes the piston upward again, preparing for the next explosion. 2. Importance: The engine is the core part of the motor, so it is commonly referred to as the engine. The main component of the engine is the cylinder, which is also the power source of the entire car.
