IPC: F02D45/00
Filed: 2000-02-18
Abstract: PROBLEM TO BE SOLVED: To prevent a misfire and a torque shock in changing over a combustion mode. SOLUTION: A request illustration torque operating means 51 calculates a request shaft based on the opening of an accelerator, an engine rotation speed Ne, and a car speed, and adds various types of loss torque to the request shaft torque to find the request illustration torque. A combustion mode changeover means 52 judges a request combustion mode from a map, etc., according to the request illustration torque and the engine rotation speed Ne and, when the request combustion mode is different from the present combustion mode, the means 52 judges it to be a combustion mode changeover request. When an estimated cylinder air-fuel ratio calculated by a cylinder air-fuel combustion ratio estimation means 56 reaches a prescribed range, the combustion mode changeover means 52 changes over the combustion mode control means 53 and 54 to change over the combustion mode.  The cylinder air-fuel ratio estimation means 56 estimates the cylinder air-fuel ratio (estimation cylinder air-fuel ratio = estimation cylinder air quantity/target fuel quantity) by supposing that it is a stratified charge combustion mode at all times, when requesting the changeover of the combustion mode, in either case of the stratified charge combustion and homogeneous combustion.
