Compared with multi-cylinder engines, single-cylinder engines are usually simpler and compact. Due to the greater potential for airflow around all sides of the cylinder, air cooling is often more effective for single cylinder engines than multi-cylinder engines. This reduces the weight and complexity of air-cooled single-cylinder engines, compared with liquid-cooled engines. WebAfter this the gudgeon-pin is forced through both the piston and the small-end eye is positioned centrally. The small end cools the shrink over the pin and also its relative rubbing movement is kept within the pin and the piston bosses. 3.
