How does an engine “suck” in air? Like during the intake stroke it goes down which creates a low pressure area and the air rushes in. But how does all that work? How does the piston going down allow air to be pulled in? LOL please explain it as simple TY!
In: Engineering
This is a fundamental rule of physics: Nature abhors a gradient.Wherever a difference exists, nature will try to eliminate that difference.
When the piston is on the intake stroke, the volume of the air-side of the piston is increasing. Air will try to fill the new volume, but can’t since there isn’t enough air available in the piston, so the pressure decreases. The pressure of the atmosphere outside the engine is now higher than the piston interior, and the weight of the atmosphere itself forces air into the piston.
