发明名称 Four cycle internal combustion engine and vehicle
摘要 A four-cycle internal combustion engine is constructed such that a structure around a cylinder head is not complicated even though the engine has a plurality of cylinders, fuel consumption is improved, and nitrogen oxides are reduced. The engine has cylinder-sided passages, through which burnt gasses pass. Also, the engine includes an inter-cylinder passage in communication with the cylinder-sided passages.
