What is the working principle of a naturally aspirated engine?

[Todd]

It is a form where atmospheric pressure forces air into the combustion chamber without the use of any supercharger. Here are the relevant introductions: 1. Advantages: Naturally aspirated engines far surpass supercharged engines in terms of smooth power output and direct responsiveness. Gasoline is directly injected into the intake manifold through fuel injectors, commonly referred to as electronic fuel injection, with the latest technology being direct cylinder injection. 2. Increasing power: Naturally aspirated means that in the first stroke mentioned above, the mixture is drawn in by the naturally formed pressure difference. Supercharged means that the gas is first compressed to increase its pressure and density, so that when the valve opens, the intake volume is increased by the pressure difference and the high pressure of the gas itself, thereby increasing power.
