Title: Controller for internal combustion engine
Inventor: AONO TOSHIHIRO
IPC: F02D11/10
Filed: 2000-07-24
Abstract: PROBLEM TO BE SOLVED: To correct the delay of response of a throttle and the delay until air is taken into a cylinder after air passes through the throttle, in order to improve responsiveness of torque of an internal combustion engine. SOLUTION: A state judging means judges the state by comparing the density inside an intake pipe measured by a density measuring means with the target density of the intake pipe found by an accelerator pedal or the other calculating means, or comparing the throttle opening measured by a throttle sensor with the throttle opening for keeping the target density. If the intake pipe density and the measured value of the throttle opening are very approximate to the target value and the speed of the throttle opening is very low, an intermediate value control means is called, or a maximum value control means and a minimum value control means are alternately called, and the throttle and the intake pipe internal pressure are controlled to such a state as to satisfy the condition.
