Abstract
An internal combustion engine includes: a cylinder block including multiple cylinders; a cylinder head; and a turbocharger including an inlet port connected to an exhaust outlet of the cylinder head. The inlet port includes a first wall portion located between one cylinder out of the two outermost cylinders and the central axis of the inlet port in the cylinder array direction, and a second wall portion located on the opposite side of the central axis of the inlet port from the first wall portion. The first wall portion includes a thick-walled portion that is greater in thickness than the second wall portion, and a thin-walled portion that is smaller in thickness than the thick-walled portion and is located upstream of the thick-walled portion in the direction of exhaust gas flow.
