Title: PREMIXED COMPRESSION IGNITION ENGINE SYSTEM
Abstract:
A premixed compression ignition engine system equipped with an engine, a fuel injection valve (37), a water injection valve (47), and a control device. The control device executes: a compression stroke intermediate injection (203) wherein the fuel injection valve injects fuel for forming an air-fuel mixture in an outer peripheral space of a combustion chamber (73); a compression top-dead-center injection (205) wherein the fuel injection valve injects fuel for forming an air-fuel mixture in a central space in the combustion chamber (73) after the compression stroke intermediate injection; and a water injection (207) wherein a water injection valve injects water into the outer peripheral space of the combustion chamber after the compression stroke intermediate injection has begun and before the compression top-dead-center injection has begun.
