Title:
CONTROL DEVICE AND CONTROL METHOD FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP2014224462
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To compatibly attain the homogenization and ignitability of air-fuel mixture.SOLUTION: A control device for an internal combustion engine includes a port-injection fuel injection valve (41) for injecting fuel into an intake port, a cylinder-injection fuel injection valve (8) for injecting fuel into a combustion chamber, a variable compression ratio mechanism (2) for changing a relative position relationship between a piston and a cylinder to vary a mechanical compression ratio, and a flow control valve (50) for varying an in-cylinder flow. Under predetermined operating conditions, the control device performs cooperative control of the sharing rate of cylinder injection to port injection, the compression ratio and the in-cylinder flow to produce the homogenization and ignitability of air-fuel mixture at a predetermined level.
