A two cylinder , two stroke cycle engine working on the constant volume cycle has a cylinder diameter of 34.3 cm, and stroke of 50.8 cm. The clearance volume is 1/15 of the swept volume, and the exhaust ports are closed by the piston when it has traveled 8cm from the bottom dead center on the compression stroke. Find the otto cycle efficiency based on the effective compression ratio of the engine.
