Oil system for a diesel engine and method for operating a diesel engine
First Claim
1. An oil system of an engine coupled to at least one soot particle filter, comprising:
- at least one oil chamber forming an oil sump;
at least one oil reservoir arranged separately from the oil chamber, the at least one oil reservoir at least partially arranged at the same geodetic height as the oil chamber;
at least one fluid connection fluidically connecting the oil chamber to the oil reservoir;
at least one electrically operable shut-off unit between the oil chamber and the oil reservoir, the at least one electrically operable shut-off unit blocking the at least one fluidic connection between the oil chamber and the oil reservoir in a blocking state and at least partially enabling fluidic connection between the oil chamber and the oil reservoir in a release state; and
at least one electronic unit connected to the electrically operable shut-off unit regulating the blocking state and the release state based on a number of regeneration operations of the at least one soot particle filter and based on a degree of dilution of an oil present in the oil chamber.

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.

9. A method for operating an oil system of an engine comprising:
adjusting a shut-off unit via an actuator between an oil chamber and an oil reservoir based on a number of particulate filter regenerations and a degree of oil dilution in the oil chamber. - View Dependent Claims (10, 11, 12, 13, 14)

15. A system, comprising:
-
a soot particle filter; an oil chamber; an oil reservoir at least partially arranged at the same geodetic height as the oil chamber; a shut-off unit between the oil chamber and the oil reservoir; and an electronic control unit connected to the shut-off unit, the electronic control unit including instructions executable to adjust a position of the shut-off unit based on a number of regeneration events of the soot particle filter and further based on an oil recovery rate. - View Dependent Claims (16, 17, 18, 19)
