Abstract: The oil side-flow cleaning device includes a heating unit (11) installed between the oil tank and the filter unit (10) so that, when the oil temperature is below a defined limit value, oil flows through the filter unit (10) in such a way as to bypass the filtering function and is heated; and so that, when the oil temperature is above the defined limit, oil flows through the filter unit (10) so as to be subjected to the oil filtering function. In addition or as an alternative, the oil side-flow cleaning device comprises a backflush unit including a backflush collecting tank (17) and a backflush nozzle (18), wherein, when the device is in backflush mode, oil flows through the filter medium (16) in a second, opposite direction as a function of the position of the backflush nozzle (18) relative to the filter medium (16).

Abstract: A cleaning device for cleaning lubricating oil which circulates in a lubricating oil circuit has an intake to be connected with the lubricating oil circuit, through which a part quantity of the lubricating oil circulating in the lubricating oil circuit is to be fed to the cleaning and a return to be connected with the lubricating oil circuit for the returning of the cleaned lubricating oil into the lubricating oil circuit.

Abstract: A valve control for a gas exchange valve of an internal combustion engine includes at least one spring element for preloading the valve in an end position and a fixing device for the releasable fixing of the valve. The spring element in a moveable insert, which by means of an actuation device is adjustable in actuation direction of the valve between an end position close to the valve disc and an end position far from the valve disc for adjusting a preload applied on the valve by the spring element.

Abstract: An exhaust gas system with a particulate filter and a regenerating burner, whose hot gas outlet is provided in the vicinity of a closed end of the filter in the form of a plurality of openings, which are arranged in one or more planes parallel to the entry surface of the particulate filter. Due to the splitting up of the hot gas flow in the burner into a plurality of smaller flows of hot gas, the mixing with the exhaust gas is so improved that directly downstream from the flame tube of the burner there is a substantially complete equalization of temperature whereby the particulate filter may be positioned very close to the burner.
