摘要： A spark ignition engine includes a main combustion chamber configured to suction a mixture through an intake port, a pre-chamber configured to communicate with the main combustion chamber, an auxiliary cylinder configured to communicate with the main combustion chamber via the pre-chamber, an auxiliary intake passage connecting the auxiliary cylinder and the intake port, an auxiliary piston, and a spark plug configured to ignite the mixture in the pre-chamber. The auxiliary piston is configured to slidably reciprocate in the auxiliary cylinder such that the mixture is suctioned from the intake port via the auxiliary intake passage and the mixture is discharged to the main combustion chamber via the pre-chamber.

摘要： A controlling method for a flame jet ignition engine includes: a setting step of setting a map as a low load operation region, a medium load operation region, and a high load operation region depending on a load which is measured at the time of the driving of the engine; and a first burning step of performing burning by being controlled with an air-fuel ratio more lean than a theoretical air-fuel ratio and reducing NOx while increasing and compensating for a burning rate depending on burning of the jet ignition apparatus, at the time of entering the low load operation region and the medium load operation region.
