Title:
CONTROL DEVICE OF IN-CYLINDER INJECTION TYPE SPARK IGNITION TYPE INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP3768296
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To carry out atmosphere correction, and ensure stable stratified combustion by providing with a control means for carrying out stratified combustion on the basis of an engine control parameter setting value on the basis of a target load value for correcting a target load value which is set according to an accelerating opening information on the basis of the operation of a driver by an environmental parameter detecting value.
SOLUTION: An ECU 70 reads in an intake air rate detected by an air flow sensor 33, a throttle valve opening detected by a throttle sensor 29, and the condition rate of an engine by an atmosphere pressure sensor 31, an intake temperature sensor 32, a crank angle sensor 17, and the like. An output demanded by a driver is memorized as target average effective pressure in the ECU 70. The target average effective pressure is atmosphere-corrected by a value which is read in the ECU 70. The control mode of an engine 1 is discriminated according to an engine speed, and an engine control parameter is set according to each control mode. Since stratified combustion is carried out by the engine control parameter, stable stratified combustion is ensured even if intake density is reduced on a high land and the like.
