Abstract
In order to provide an oil separator for separating oil from a blowby gas of a cylinder head of an internal combustion engine, which oil separator is manufactured separately from a basic body of a cylinder head cover but may nevertheless be easily integrated into the cylinder head cover, it is proposed that the oil separator comprises an oil separator module, which is manufactured separately from a basic body of a cylinder head cover and comprises a cyclone plate having at least one cyclone as well as a base plate, wherein the cyclone plate is fastened to the base plate and the oil separator module is fastenable to the basic body of the cylinder head cover.
Claims26
Oil separator for separating oil from a blowby gas of a cylinder head of an internal combustion engine,
- wherein the oil separator comprises an oil separator module, which is manufactured separately from a basic body of a cylinder head cover and comprises a cyclone plate having at least one cyclone and a base plate, wherein the cyclone plate is fastened to the base plate and the oil separator module is fastenable to the basic body of the cylinder head cover;
- and
- wherein the cyclone axis of the cyclone in the fitted state of the oil separator forms with the horizontal an angle of at most approximately +/−20°.
Method of manufacturing a cylinder head cover with an integrated oil separator, comprising the following method steps:
- fastening a cyclone plate having at least one cyclone to a base plate to form an oil separator module;
- fastening the oil separator module to a basic body of the cylinder head cover;
- wherein the cyclone axis of the cyclone in the fitted state of the oil separator forms with the horizontal an angle of at most approximately +/−20°.
Oil separator for separating oil from a blowby gas of a cylinder head of an internal combustion engine,
- wherein the oil separator comprises an oil separator module, which is manufactured separately from a basic body of a cylinder head cover and comprises a cyclone plate having at least one cyclone and a base plate, wherein the cyclone plate is fastened to the base plate and the oil separator module is fastenable to the basic body of the cylinder head cover;
- and
- wherein the cyclone plate comprises at least two cyclones.
Oil separator for separating oil from a blowby gas of a cylinder head of an internal combustion engine,
- wherein the oil separator comprises an oil separator module, which is manufactured separately from a basic body of a cylinder head cover and comprises a cyclone plate having at least one cyclone and a base plate, wherein the cyclone plate is fastened to the base plate and the oil separator module is fastenable to the basic body of the cylinder head cover;
- and
- wherein the cyclone axes of at least two cyclones are mutually offset in a direction oriented horizontally in the fitted state of the oil separator.
Oil separator for separating oil from a blowby gas of a cylinder head of an internal combustion engine,
- wherein the oil separator comprises an oil separator module, which is manufactured separately from a basic body of a cylinder head cover and comprises a cyclone plate having at least one cyclone and a base plate, wherein the cyclone plate is fastened to the base plate and the oil separator module is fastenable to the basic body of the cylinder head cover;
- and
- wherein the oil separator module comprises a settling chamber, which is delimited by the base plate and by the cyclone plate and is connected by a cyclone approach flow channel to the interior of at least one cyclone, wherein the oil separator comprises at least two cyclones and wherein the settling chamber is connected to both cyclones by in each case at least one cyclone approach flow channel.
Oil separator for separating oil from a blowby gas of a cylinder head of an internal combustion engine,
- wherein the oil separator comprises an oil separator module, which is manufactured separately from a basic body of a cylinder head cover and comprises a cyclone plate having at least one cyclone and a base plate, wherein the cyclone plate is fastened to the base plate and the oil separator module is fastenable to the basic body of the cylinder head cover;
- and
- wherein the base plate is provided with at least one baffle element, which guides blowby gas in the direction of a cyclone approach flow channel.
Cylinder head cover, comprising at least one oil separator for separating oil from a blowby gas of a cylinder head of an internal combustion engine,
- wherein the oil separator comprises an oil separator module, which is manufactured separately from a basic body of the cylinder head cover and comprises a cyclone plate having at least one cyclone and a base plate, wherein the cyclone plate is fastened to the base plate and the oil separator module is fastenable to the basic body of the cylinder head cover;
- and
- wherein the oil separator module is disposed in the interior of the cylinder head cover.
