ABSTRACT:
An exhaust control system for a two-cycle engine for controlling the effective compression ratio. The exhaust control valve is operated by a servo mechanism to maintain the appropriate compression ratio in response to engine running conditions. To facilitate servicing, the exhaust control valve is rotatably journalled within the engine cylinder block in a removable sleeve. In addition, a manual operator is provided for manually rotating the exhaust control valve for cleaning operation and to reduce sticking if corrosion occurs.
