Title: Internal combustion engine
Inventor: PETSCHICK SIEGFRIED DIPL ING
IPC: F01P11/08
Filed: 1989-01-16
Abstract: Internal combustion engine with a cooling-air fan and a radiator in which the medium to be cooled undergoes indirect heat exchange with the cooling air. The block radiators installed in the case of air-cooled internal combustion engines are relatively large, take up a relatively large amount of space and have a disadvantageous effect on the overall height of the engine. A flat oil cooler is not designed for excessively high cooling-air pressures. By dividing the oil cooler into several parts which are acted upon in succession by the same flow of air, it is possible to use a flat oil cooler in the case of an air-cooled internal combustion engine and, at the same time, to exploit the full cooling power. <IMAGE>
