<p><P>PROBLEM TO BE SOLVED: To provide a compact and inexpensive engine generator capable of changing the number of revolutions of an engine in accordance with load without detecting an output current and output voltage and making improvement of fuel economy and stable supply of electric power compatible. <P>SOLUTION: The number of revolutions of the engine NE (the number of revolutions of the engine NEavg) and degree of opening of a throttleθTH are detected (calculated) (S10, S14, S16), and engine output OP is inferred (S20, S28) based on these values. Target number of revolutions of the engine NED is changed to switch between first target number of revolutions NED1(low load time target number of revolutions) and second target number of revolutions NED2 set to be larger than the first target number(high load time target number of revolutions) based on the inferred engine output OP (S26, S34). <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
