Title: Torque control device for engine
Inventor: YANO HIROSHI
IPC: F02D43/00
Filed: 1999-12-02
Abstract: PROBLEM TO BE SOLVED: To permit torque control in a low torque area wherein torque is uncontrollable even if the operating angle of an intake valve is controlled to be a minimum operating angle, while suppressing the generation of torque step difference in an engine constituted to control the operating angle of the intake valve according to target torque. SOLUTION: When target torque is lowered from the high torque side (S2), the operating angle of the intake valve is brought close to a minimum operating angle in proportion to the lowering of the target torque (S3). After the operating angle becomes the minimum operating angle (S4), a throttle valve is closed to control the air quantity to be the value corresponding to the target torque (S5). In the closing start area of the throttle valve, the operating angle of the intake valve is slightly enlarged from the minimum operating angle to avoid torque step difference generated by the abrupt decrease of the air quantity caused by the closing control of the throttle valve (S5).
