Fuel Economy in Two-Stroke Spark Ignition Engines - A New Technique in the Scavenging Process 871226

In the conventional scavenging process of the two-stroke spark ignition engines, a part of the fresh mixture leaves the cylinder along with the burnt products and contributes heavily towards the hydro-carbon emission in the engine exhaust with high S. F. C. In this investigation an attempt is made to reduce the fresh mixture loss to the exhaust line during the scavenging process, by incorporating reed valves at the transfer ducts. It is observed that this approach reduces the fuel consumption to the engine without any power loss and decreases the hydro-carbon content in the engine exhaust.
