Abstract
A module for an internal combustion engine formed as a unit comprising an oil filter for lubricating oil of the engine and an oil separator for crankcase ventilation gas and which, as a whole, is attached to the engine by a flange connection with flow connections. An oil duct for oil to be filtered and an oil duct for filtered oil extend through the flange. A ventilation duct for ventilation gas and an oil return duct for separated oil also extent through the flange. A drain duct connected to the crankcase via the flange connection is provided for draining the oil filter upon a replacement of the filter element. The drain duct, the ventilation duct and the oil return duct are 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.
Claims21
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.
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 a pressure regulating valve, positioned in a flow path of the crankcase ventilation gas cleaned in the oil separator, that is used to control the pressure present in the crankcase, and wherein the pressure regulating valve is connected to the oil separator and comprises a line connection for a gas line for crankcase ventilation gas having been deoiled in the oil separator, the gas line running to an intake section of the internal combustion engine.
A module for an internal combustion engine, which is formed as a structural unit comprising at least one oil filter for lubricating oil of the internal combustion engine and one oil cooler for cooling the lubricating oil by means of cooling water 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 first cooling water duct runs from the internal combustion engine to the oil cooler and wherein a second cooling water duct runs from the oil cooler to the internal combustion engine, comprising:
- the module having at least one control element directing the cooling water to different flow paths of the cooling water circuit, and
- at least one further cooling water duct connected to at least one of the cooling water ducts and supplying cooling water to or from the control element being provided in the module.
