for those of us who are a little slower 4 stroke has 4 distinct conditions during operation. 1. suck (intake) 2. Squeeze (compression) 3. Bang (ingition of fuel) 4.Blow. (Exhaust pushed out of cyl.)
a 2 stroke diesel essentially combines the first and last strokes, when the piston is at bottom of it;s stroke it opens a set of ports leading to a pressurized air box. when these ports are open it allows the clean, pressurized air to blow the dirty exhausted air out the open exhaust valves. leading to the squeeze and bang strokes. Hope this helps
cessna 310would someone explain the difference between a "two-stroke" and "four-stroke"
would someone explain the difference between a "two-stroke" and "four-stroke"
A two stroke engine has combustion every time the piston comes to the top of the stroke....a four stroke engine has combustion every 2nd time the piston comes to the top of the stroke.
Never too old to have a happy childhood!
2 stroke -- requires two complete strokes of the piston in the cylinder for every power stroke (the stroke that generates power)
4-stroke -- requires four complete strokes for every power stroke.
Rather than spend 10 minutes describing this, see these links, complete with animations:
