WebSep 27, 2013 · To determine the gas-exchange performance, we need to evaluate the effective flow areas of the intake and exhaust ports or valves during the scavenging process. The ultimate goal is to deliver the same trapped air mass for all configurations. In a two-stroke engine, the intake and exhaust ports are open at the same time. WebPort timing in two stroke engine Two-stroke engine has no valves instead they have ports. They are inlet port, transfer port (transfer fuel from the crankcase to the cylinder) and an exhaust port. The sequence of operation of the ports is controlled by reciprocating movement of the piston in the engine cylinder.
