Abstract
An internal combustion engine includes a cylinder, a piston, a crankshaft, a cylinder igniter, an intake passage, a fuel supplier, an exhaust passage, a catalytic converter disposed in the exhaust passage, an exhaust igniter that is disposed upstream of the catalytic converter in the exhaust passage and s generates a spark in the interior of the exhaust passage, and a controller that controls a preheating process for heating the catalytic converter by controlling supply of the air-fuel mixture to the exhaust passage and ignition of the air-fuel mixture by the exhaust igniter. The internal volume of the exhaust passage from the cylinder to an installation position of the exhaust igniter is equal to or less than a volume of the air-fuel mixture discharged from the cylinder in one exhaust stroke in the exhaust passage.
