Each of the sub-exhaust valves is mechanically opened in synchronization with the start of an exhaust process of a corresponding one of engine cylinders. Each of the EGR valves is electrically opened to supply part of exhaust gas discharged through one of the subexhaust valves from one of the engine cylinders which is in the exhaust process to mix it with fuel sprayed into another of the engine cylinders which is in an intake process for promoting atomization of the fuel spray and achieving EGR.
