Line multicylinder internal combustion engine

摘要

An in-line multicylinder internal combustion engine comprising an engine block including a cylinder crank housing having disposed therein a plurality of approximately horizontally disposed cylinders and a cylinder head mounted on the cylinder crank housing. An approximately horizontally disposed crankshaft is disposed in the cylinder crank housing for reciprocably displacing pistons in the respective cylinders, and an exhaust system is provided which begins at an underside of the cylinder head. A first housing cover is disposed on the cylinder head and extends in a longitudinal direction of the crankshaft with a second cover being disposed on the cylinder crank housing in an area of the crankshaft and extenging in a longitudinal direction thereof. The first and second housing covers each have essentially smooth lateral outer housing walls, with a cooling arrangement being mounted above an upper forward edge of the engine block. At least one first auxiliary unit for the engine is disposed on top of the engine block behind the cooling arrangement and a housing part is connected to and disposed below the cylinder crank housing. At least one second auxiliary unit for the engine is accommodated by the housing part. A part of the exhaust gas system extends next to the housing part with such part of the exhaust gas system being shaped as a housing member.
