Title:
CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP2003148181
Kind Code:
A
Abstract:

To secure the exhaust emission controlling performance and the operability even when a trouble related to the control system of an adjustable valve mechanism occurs.

When a trouble related to the control system of the adjustable valve timing mechanism (VTC) is detected (S2, S3), the operation region of the engine is detected and the trouble-time control is executed according to the operation region (S4-S8). As a result, the quantity of the valve overlapping is reduced and the external EGR quantity is increased. At the time, the torque compensation is executed in a first operation region for compensating the torque reduction following the trouble-time control (S7). On the other hand, in second and third operation regions where troubles cannot be controlled by the torque compensation, the gear ratio of a non-stage transmission CVT is changed to execute the output compensation control for increasing the engine rotation speed Ne (S8).
