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
– The cylinder is full of piston.
– The intake valve opens and the piston is pulled to the bottom of the cylinder which fills in with air just like a syringe.
– The valve closes trapping the air, the piston raises thus compressing the air, gas is squirted in via the injector and the spark plug makes it go bang forcing the piston to the bottom of the cylinder.
– The exhaust valve opens as the piston rises pushing the combustion products out the muffler.
