Title: Control device of cylinder resting engine
Inventor: KOMORI KIYOSHI
IPC: F01L13/00
Filed: 1996-09-06
Abstract: PROBLEM TO BE SOLVED: Generation of torque shock is prevented by carrying out resting and resting release of each cylinder with constant regularity even when a driving state of an engine changes. SOLUTION: Solenoid valve ON timing is set by preceding by change-over responding time from change-over reference timing in consideration of responsive delay of rising of hydraulic pressure in case of changing full cylinder operation over to cylinder resting operation by supplying hydraulic pressure to a cylinder resting mechanism of each cylinder by a solenoid valve. The change-over responding time is variable, and it is set by map retrieval with engine speed, hydraulic pressure and oil temperature as parameter. Consequently, it is possible to raise hydraulic pressure within a regularity establishing region set between a valve lift of a #3 cylinder and a valve lift of a #1 cylinder and to carry out cylinder resting with regularity in sequence of #1 cylinder to #2 cylinder to #3 cylinder.
