Multiple cylinder two-cycle engine

Abstract

Abstract PURPOSE:To time air exhausting highly accurately by providing an exhaust valve drive shaft so as to penetrate the portion where exhaust air passages are close to each other. CONSTITUTION:Exhaust passages 15A and 15B communicated to exhaust ports 14A and 14B respectively are arranged in such a manner that each part of the passages is close to each other. An exhaust valve drive shaft 16 is provided so as to penetrate the portion where each part of the passages is close to each other. Exhaust valves 18A and 18B are supported by the exhaust valve drive shaft 16. This prevents each exhaust valve from varying in rotating angle thus making it possible to time air exhausting highly accurately.
