Two Stroke Engine Using Reed Valves

ABSTRACT


Fresh charge loss during the scavenging process of a two stroke S.I engine is known to be the principal reason for its high specific fuel consumption and high hydrocarbon emission. In order to minimize the fresh charge loss to the exhaust a new scavenging system had been developed. To achieve better performance from this scavenging system, control of air flow through reed valve is necessary, since it will affect the mixture quality of the trapped charge. In this paper, improved performance and reduction in exhaust emissions are reported by optimizing the amount of atmospheric air entering through the reed valves in a small capacity, two stroke S.I engine.

It will be helpful for a common man to understand the location of reed valve of a two stroke engine

Kindly furnishme with a sketch showing where a rteed valve is usually mounted whether it is before the inlet port or past exhaust port.
