Abstract
A multi-cylinder internal combustion engine includes, per each of a plurality of cylinders, a main combustion chamber, an auxiliary combustion chamber in which ignition is effected by means of a spark plug and a torch nozzle through which a torch flame resulting from combustion within the auxiliary combustion chambers enters the main combustion chamber to initiate combustion therein. An engine head of the engine has a plurality of exhaust passageways, corresponding in number to half of the plurality of cylinders. Each of the plurality of exhaust passageways has a discharge port, to which an exhaust manifold is connected, and extends from the discharge port to two of exhaust valves which are arranged next to each other. Within each of the plurality of exhaust passageways, a port liner is installed to keep exhaust gas flowing along the exhaust passageway warm.
