Abstract
An internal combustion engine, especially a diesel internal combustion engine, having at least one intercooler, at least one control unit, at least a first and a second cooling circuit, whereby the cooler of the first cooling circuit is flow-connected to a cooling circuit of the internal combustion engine, while the cooler of the second cooling circuit of the internal combustion engine is flow-connected to the intercooler.
Claims20
An arrangement for an internal combustion engine comprising:
- at least one intercooler;
- at least one control unit;
- a first and a second cooling circuit, a first cooler of the first cooling circuit being configured for delivering coolant via the first cooling circuit to the internal combustion engine, while a second cooler of the second cooling circuit is configured for delivering coolant via the second cooling circuit to the at least one intercooler;
- an active crankcase ventilation system operatively connected to at least one Venturi tube, wherein the at least one Venturi tube is designed as an ejector pump connected between the active crankcase ventilation system and the at least one intercooler;
- and
- a valve cover, wherein the at least one intercooler, the at least one control unit, and the active crankcase ventilation system are fixed directly on top of the valve cover.
