<p><P>PROBLEM TO BE SOLVED: To improve fuel economy of an internal combustion engine and to decrease more harmful matters in exhaust emission by more accurately detecting the value of intake negative pressure P in an intake passage of the internal combustion engine body and supplying fuel according to the detection value in the internal combustion engine. <P>SOLUTION: The internal combustion engine 18 includes an intake pipe 34 extended from the internal combustion engine body 19 to communicate the internal intake passage 33 to an intake passage 27 formed in the internal combustion engine body 19, a fuel feeding means 36 for feeding fuel to the internal combustion engine body 19, an intake negative pressure sensor 43 for detecting the intake negative pressure P in the intake passage 33 of the intake pipe 34, and a control device 44 for controlling the feed quantity of fuel to the internal combustion engine 19 by the fuel feeding means 36. The intake negative pressure sensor 43 detects the intake negative pressure P at the downstream end of the intake passage 33 of the intake pipe 34. <P>COPYRIGHT: (C)2004,JPO</p> |
