<P>PROBLEM TO BE SOLVED: To employ an inexpensive temperature sensor by making it perform the detection of an engine exhaust-heat temperature in a low-temperature region. <P>SOLUTION: In a prescribed point outside a muffler 30 or in a prescribed point outside an exhaust pipe 31 constituting an exhaust passage 3 at the downstream side in the exhaust direction rather than the muffler 30, there is arranged the exhaust temperature detection sensor 6 which detects that an atmosphere temperature in the prescribed point outside the muffler 30 has reached a prescribed temperature on the basis of a rise of an internal temperature of the muffler 30, or an atmosphere temperature in the prescribed point outside the exhaust pipe 31 has reached a prescribed temperature on the basis of a rise of an exhaust temperature in the exhaust pipe 31. <P>COPYRIGHT: (C)2013,JPO&INPIT |
