Abstract: A method and system for determining a cause of error in an agricultural working machine with a faulty component is disclosed. An analysis routine may analyze various types of data, such as operating data of the agricultural working machine, including workload data of the agricultural working machine, and/or design data of the agricultural working machine, such as design data of the faulty component of the agricultural working machine, in order to determine a cause of error, as indicated by cause of error data. Specifically, the analysis routine may analyze one or both of operating data and design data in order to determine whether a workload of the agricultural working machine and/or a design of the agricultural working machine, such as the design of the faulty component of the agricultural working machine, can be excluded and/or identified as the cause of error.

Abstract: A method for servicing or repair of an agricultural work machine, wherein an outage duration probability and/or a damage probability of the agricultural work machine and/or of a component part of the agricultural work machine is determined in an analysis routine based on operating data of the agricultural work machine, and wherein a delivery routine comprising a delivery of a replacement part corresponding to a component part of the agricultural work machine to a service point associated with the agricultural work machine is initiated based on the analysis routine for reducing the outage duration probability and/or the damage probability.

Abstract: An engine control system includes an injection determination module and an injection regulation module. The injection determination module determines a desired rate of hydrocarbon (HC) injection into exhaust gas produced by an engine for regeneration of a particulate matter (PM) filter. The injection regulation module increases a rate of HC injection from a first rate to the desired rate during a predetermined period before regeneration of the PM filter, wherein the predetermined period is based on a difference between a predetermined temperature and a temperature at an outlet of an oxidation catalyst (OC).

Abstract: A method and control system for controlling an engine during diesel particulate filter regeneration includes a diesel particulate filter (DPF) regeneration request module that generates a DPF regeneration request signal and an idle condition module that generates an idle condition signal when the engine is at an idle condition. A DPF regeneration control module initiates a timer in response to the DPF regeneration request signal and the idle condition signal. The DPF regeneration control module controls the engine oxygen level to a second level less than a first level corresponding to a non-idle speed level, and after a time period, controls the engine to generate oxygen at a third level greater than the second level.

The control system also includes a DPF regeneration control module that controls the oxygen level in the exhaust based on an oxygen level signal corresponding to an oxygen level in the exhaust and a DPF inlet temperature signal corresponding to the DPF inlet temperature.

Abstract: An engine control system includes an injection determination module and an injection distribution module. The injection determination module determines a desired amount of hydrocarbons (HC) to inject into exhaust gas produced by an engine for regeneration of a particulate matter (PM) filter. The injection distribution module controls a ratio of auxiliary injection to post-combustion injection based on engine load, engine speed, and the desired amount of HC injection, wherein auxiliary injection includes injecting HC into the exhaust gas, and wherein post-combustion injection includes injecting HC into cylinders of the engine during a period after combustion.
