Patent number: 11187174Abstract: A method for monitoring crankcase pressure, in which a learning curve is calculated according to a target-actual deviation of the crankcase pressure, the target crankcase pressure is adjusted according to the learning curve, and a limit curve is calculated according to the target crankcase pressure. The actual crankcase pressure is monitored for exceedance of the limit curve. After an engine start, upon identification of a steady-state operation of the internal combustion engine, the actual crankcase pressure is compared with a limit value and, if the limit value is identified as being exceeded, the learning curve and, as a result, the limit curve are reset to their initial values.Type: GrantFiled: November 16, 2017Date of Patent: November 30, 2021Assignee: MTU FRIEDRICHSHAFEN GMBHInventors: Johannes Baldauf, Patrick Dussler, Eugen Bucher, Vadzim Khakholka

Patent number: 9422885Abstract: The present invention relates to a method for reducing the particle emissions of an internal combustion engine over its service life. The number of cylinders of the internal combustion engine in which post-injection is carried out is incrementally increased during the service life of the internal combustion engine. The increase in the number of cylinders receiving a post-injection may depend upon at least one parameter, which may be a running time, a distance performance, a particle concentration in exhaust gas, a load profile, or other parameter. The individual cylinders receiving post-injection may be changed to distribute wear.Type: GrantFiled: June 19, 2015Date of Patent: August 23, 2016Assignee: MTU Friedrichshafen GmbHInventors: Michael Prothmann, Johannes Baldauf, Markus Fleckhammer
