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 and piston are precisely machined so along with the lubricants it creates pretty much an airtight chamber. So after the exhaust gases are expelled on the upstroke the valve opens to allow fresh air in and the piston pulls the air in on the downstroke since it creates a vacuum in the cylinder
