A two-stroke internal combustion engine is provided including an engine block, a combustion chamber defined in the engine block and adapted to have a piston reciprocate therein along an axis between a top dead center position and a bottom dead center position, and to have air and fuel combusted therein, thereby causing production of an exhaust gas and at least partially causing the piston to reciprocate, the internal combustion engine further comprising an exhaust port communicating with the combustion chamber and adapted to conduct the exhaust gas away from the combustion chamber, a sensor chamber at least partially defined in the engine block, a passage extending from the sensor chamber to the combustion chamber at a location axially between the exhaust port and the top dead center position, valve structure, operable in the passage for allowing flow of exhaust gas from the combustion chamber to the sensor chamber, and for preventing flow of non-combusted air and fuel from the combustion chamber to the sensor chamber, an exit conduit adapted to conduct at least a portion of the exhaust gas in the sensor chamber away from the sensor chamber, and structure at least partially located in the sensor chamber for sensing a condition in the exhaust gas. |
