Embodiment Construction

[0029] The following description relates to systems and methods for an oil system of a diesel engine, particularly a diesel engine of a motor vehicle. The diesel engine may comprise: at least one soot filter; at least one oil chamber forming an oil sump; at least one oil reservoir arranged separately from the oil chamber and at least partially arranged at the same elevation as the oil chamber ; At least one fluid connection, which connects the oil chamber to the oil reservoir in a communicative manner, and at least one electrically operated shut-off unit is arranged on this fluid connection. A disconnection unit blocks the fluid connection in the blocking state and at least partially releases the fluid connection in the release state; and at least one electronic unit connectable to the disconnection unit according to a signal. Furthermore, a method for operating a diesel engine, in particular a diesel engine of a motor vehicle, comprising at least one soot filter and at least ...

Abstract

An example oil system is provided, including at least one oil chamber forming an oil sump, an oil reservoir, which is arranged separately from the oil chamber, and at least partially arranged at the same geodetic height as the oil chamber, and at least one fluid connection which connects the oil chamber to the oil reservoir. An electric shut-off unit may block the fluid connection of the oil chamber to the oil reservoir in a blocking state and at least partially release the same in a release state. In order to extend oil changing intervals, a number of regeneration operations and an estimate of an instantaneous degree of dilution of oil present in the oil chamber, may be used for activating the electric shut-off unit to connect or block the fluidic connection between the oil chamber and the oil reservoir.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from German Patent Application No. 102015207287.8 filed April 22, 2015, the entire content of which is hereby incorporated by reference for all purposes. technical field [0003] The present application relates to methods and systems for controlling a vehicle engine. Background technique [0004] A soot filter used for filtering combustion gases of a diesel engine in order to reduce particulate emissions of the diesel engine is generally arranged in an exhaust passage of the diesel engine. Particles filtered from the exhaust gas are stored in the soot filter. The soot particulate filter is loaded with particulates causing exhaust back pressure which limits the power of the diesel engine. If the exhaust emissions of a diesel engine are severely impeded by the exhaust backpressure, the soot filter must be regenerated. For this purpose, a regeneration operation is used, by means of whic...
