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

Answer Posted / bejoy

in 2 stroke engines too valves can be designed and also
there are 2 stroke diesel engines with valves..
but common 2 stroke engines like that of a kinetic honda
engine don't have valves bcos it simplifies the construction
a lot and by arranging the ports in such a manner it
achieves the purpose..bt then it creates a lot of
inefficiency and waste of lubricant.. so no valves are used
where these can be compromised or minimised by other methods..
