Why do 4 stroke engine uses valves while 2 stroke engine uses
ports ????

Answer Posted / yash chauhan

basically ports and valves are same, they are used interchangeably most of the times but the basic difference in between them is Ports are mainly the opening in the cylinder head they allows the passage of gas/mixture to the cylinder whereas Valve are moving up and down allowing the gases to come or to escape from engine cylinder.
