Emission Control by Selective Exhaust Gas Recirculation Scavenging System in Two-Stroke Engine

Ramakrishnan, V. / Purushothaman, K. / Mohammed Ghouse, S.

For small two-stroke engines, it is important that the newer concepts/systems should not adversely affect their existing advantages, particularly those of simplicity and low production and maintenance cost. With this in mind, we decided to do our project for improvement of the conventional engine. The project also aims to reduce short circuiting of fresh charge by admitting cooled exhaust gas to pass through reed valves fitted at the upper end of the transfer passage, in a crank case scavenged two-stroke engine. This results in appreciable decrease in specific fuel consumption and in HC/CO emissions. Major works involved in this project are designing and machining two aluminium flanges to accommodate the reed valves, and also providing an arrangement at the upper end of the transfer passage in the engine cylinder to fasten the flange and fabrication of heat exchanger in order to cool the exhaust gas which is at a temperature of about 400 °C to avoid pre ignition inside the engine cylinder. The performance of the engine is tested using eddy current dynamometer.
