Title:
内燃機関の制御装置
Document Type and Number:
Japanese Patent JP7240228
Kind Code:
B2
Abstract:
To provide a control device of an internal combustion engine which can surely set a valve at valve timing appropriate to a succeeding start time at a stop of the internal combustion engine.SOLUTION: In a control device of an internal combustion engine having a variable valve timing device (40) for changing the valve timing of an intake valve (22) or an exhaust valve (23) by using an electric motor (41), the control device performs a first operation (Q1) for mostly retarding the valve timing of the intake valve by carrying electricity to the electric motor according to an engine stop requirement of the internal combustion engine, or mostly advancing the valve timing of the exhaust valve, and a second operation (Q2) for mostly retarding the valve timing of the intake valve which is operated by the first operation by carrying electricity to the electric motor after the rotation of the internal has been completely stopped, or mostly advancing the valve timing of the exhaust valve which is operated by the first operation.SELECTED DRAWING: Figure 3
