Title: Method for controlling idling rotation speed of internal combustion engine
Inventor: KUDO TORU
IPC: F02D31/00
Filed: 2001-03-29
Abstract: PROBLEM TO BE SOLVED: To provide an idling rotational speed control method, capable of smoothly making an actual engine rotational speed approach the target value. SOLUTION: Then a driver releases an accelerator in a normal traveling state of a vehicle, an engine revolution is lowered to carry out a compensation injection for compensating the injection amount in the vicinity of the target engine revolution (Neisc+ΔN1<=Ne<=Neisc+ΔN2). Such a compensation injection amount is calculated from the reduction speed dNe/dt, and is gradually increased by a reflection rate coefficient Kd, so that the compensation injection amount is reflected in 100%, when the engine revolution (Ne) reaches the target one (Neisc). Thereby, the reduced speed of engine revolution can be delayed, as compared with the conventional idling rotational speed control (PI feedback control). Therefore, since the engine revolution can be prevented from the dropping off the target revolution to a large extent, it can be made to approach the target smoothly.
