Title:
CONTROL DEVICE FOR SPARK IGNITION TYPE ENGINE
Document Type and Number:
Japanese Patent JP3963144
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To restrict the generation of knocking, and to effectively perform combustion by the compression self-ignition in following cylinders in a wider operation range.
SOLUTION: In a partial load range of the engine, the intake/exhaust flowing condition is controlled so that the burned gas discharged from preceding cylinders 2A and 2D on the exhaust stroke side among pairs of cylinders, which have an exhaust stroke and an intake stroke overlapped with each other, is led into following cylinders 2B and 2C on the intake stroke side through a gas passage 22 provided between the cylinders. In an operation range of a special operation mode, a combustion condition control means 44 controls the following cylinders 2B and 2C to perform the combustion by the compression self-ignition. In a compression self-ignition range of the following cylinders, when operating condition is easy to generate knocking, a fuel injection control means 45 controls to relatively retard the fuel injection timing in relation to the following cylinders in comparison with the operating condition hard to generate knocking.
