Abstract

A V-type internal combustion engine has a mechanically driven supercharger located essentially between the V-shaped cylinder banks of the engine. In addition, an intercooler is located downstream of the supercharger and has an intake plenum on the outlet side, which is connected by intake pipes with the air intakes of the cylinders of both cylinder banks. In order to provide an internal combustion engine with compact, easily managed mechanical supercharging, characterized by agile response, the supercharger and the intercooler form a preassembled module. The supercharger is located above the intercooler in the installed position, and the intake plenum is located on top of the intercooler but below the supercharger between the V-shaped cylinder banks.
