Title:
Variable combustion system for internal combustion engine
Document Type and Number:
Japanese Patent JP6320882
Kind Code:
B2
Abstract:
A variable combustion system for an internal combustion engine, which suppresses mechanical compression ratio change control by a variable mechanical compression ratio control mechanism and carries out internal EGR amount change control by a variable valve actuating control mechanism on a preferential basis in a first operating region in which a compression self-ignition combustion is carried out, and which suppresses the internal EGR amount change control by the variable valve actuating control mechanism and carries out the mechanical compression ratio change control by the variable mechanical compression ratio control mechanism on a preferential basis in a second operating region in which a spark ignition combustion is carried out.
