Patent ID: 7069900

Claim:
A module for an internal combustion engine, which module is formed as a structural unit comprising at least one oil filter for lubricating oil of the internal combustion engine and one oil separator for crankcase ventilation gas of the internal combustion engine and which, as a whole, is connected to the internal combustion engine by means of a flange connection between a module flange and an engine flange with flow connections being established, wherein an oil duct for oil to be filtered runs from the internal combustion engine to the oil filter and an oil duct for filtered oil runs from the oil filter to the internal combustion engine, wherein a ventilation duct for crankcase ventilation gas runs from the crankcase of the internal combustion engine to the oil separator and wherein an oil return duct for separated oil runs from the oil separator to the crankcase of the internal combustion engine, comprising: a drain duct connected to the crankcase of the internal combustion engine via the flange connection being provided in the module for draining the oil filter upon a replacement of the filter element, and the drain duct, the ventilation duct and the oil return duct being united in the flange connection and along at least a part of their length in the module in a single combined gas-and-oil duct, wherein the module comprises an oil cooler for cooling the lubricating oil of the internal combustion engine by means of internal combustion engine cooling water, wherein the oil cooler includes an oil drain to be enabled in case of both an oil change and upon replacement of the filter element, and wherein the oil drain leads to the combined gas-and-oil duct.
