Title: Control device for internal combustion engine
Inventor: AOYAMA SHUNICHI
IPC: F02B75/04
Filed: 2001-03-27
Abstract: PROBLEM TO BE SOLVED: To cope with both of a big rise of an exhaust temperature due to a lag of ignition timing and operation performance in a cold state, and to raise the temperature of a catalyst early. SOLUTION: A control device is provided with an adjustable valve mechanism for variably controlling opening and closing timing of an intake air valve and a variable compression ratio mechanism for variably controlling a compression ratio ε. The adjustable valve mechanism is formed of a lift and an operation angle variable mechanism capable of continuously controlling the lift and operation angle of the intake air valve for enlargement and reduction and a phase variable mechanism for changing a lift center angle ϕ. When operating high idling after cold state starting, the compression ratio ε is set higher, and the operation angle of the intake air valve is reduced to delay the intake air valve opening timing from a top dead center. At the same time, ignition timing is remarkably delayed from a point MBT.  A large lag of the ignition timing is attained by an increase in flow speed by the development of negative pressure inside a cylinder, securing the real compression ratio, and improving the compression ratio ε.
