In auto mobile industry for any type of vehicle how can we
differentiate 2 stroke and 4 stroke engine....

Answer Posted / karthick

i think we can differentiate with valves and ports.4 stroke
has only two valves (inlet and exhaust) but 2 stroke has
ports(three ports inlet,exhaust and transfer port).for two
stroke we will be drawing port timing diagrams and for four
stroke we will be drawing valve timing diagrams to find out
the positions of cranshaft w.r.t top and bottom dead centre
