2 Stroke vs 4 Stroke Help
Well in an effort to learn more about the mechanical workings of my machines I picked up a few books from teh library and some off of amazon. However I am kind of confused and I was hoping someone could explain to me how a 2 stroke engine works. Correct me if I am wrong, in a 4, the piston moves down, drawing in air/gas, the piston moves back up (from swinging force? or being attached to the other pistons?) compressing the air/gas mixture, the spark plug ignites the mixture and sends the piston back down, again the piston moves up and releases the exaust.
I am confused because from what I have read, a 2 stroke draws in teh air/gas as the piston moves down, it comes back up and the charge is ignited. Is another air/gas charge inserted immediately after teh explosion? Also what happens to the exaust? Thanks for the help.
