PROBLEM TO BE SOLVED: To securely prevent worsening of exhaust emission by providing a temperature hold means holding a temperature of an exhaust air purifying part for purifying exhaust air from an internal combustion engine above a function activation temperature. SOLUTION: This hybrid engine has a power distribution mechanism 4 distributing rotation force of an output shaft 1a of an internal combustion engine 1 to a power generator 3 and a rotary shaft 2a of an electric motor 2. Moreover, it is provided with an inverter 5 which selectively applies power generated by the power generator 3 to the electric motor 2 and a battery 6 or condensed power of the battery 6 to the electric motor 2. In this case, an exhaust air purifying catalyst 14 as an exhaust air purifying part is provided on the halfway of an exhaust pipe 13 to hold a temperature of the exhaust air purifying catalyst 14 above a function activation temperature at all times irrespective whether the internal combustion engine is in an operation state or a non-operation state. That is, a catalyst temperature sensor 15 is provided to operate a heating means so that a temperature of the exhaust air purifying catalyst 14 is held above the function activation temperature when the temperature detected by the sensor 15 is dropping. |
