摘要

PPROBLEM TO BE SOLVED: To provide a premixed compression ignition engine and its intake air control method capable of eliminating excess/shortage of intake gaseous mixture quantity generated at the time of switching spark ignition combustion and premixed compression ignition combustion regardless of presence/absence of a supercharger. PSOLUTION: An intake air passage 10 communicating with a combustion chamber 3 is provided with a first branch intake air passage 16 having an intake air port 4 at an end and an intake manifold including a surge tank 13, a second branch intake air passage 17 having an intake air port 14 at an end and an intake manifold including a surge tank 23, and a common intake air passage 19 communicating with respective end parts of the first branch intake air passage 16 and the second branch intake air passage 17. A mixer 11 for generating mixed air is provided in the common intake air passage 19. A switch valve 18 for communicating the common intake air passage 19 with at least one of the first branch intake air passage 16 and the second branch intake air passage 17 is provided in the intake air passage 10.
