Delivery device for delivering and heating a medium
A delivery device for delivering a medium and for heating the medium to be delivered, having a vehicle pump, an electric motor for driving the vehicle pump and a control unit for controlling the electric motor. For heating the medium in the vehicle pump, the control unit is designed to generate a first alternating electrical current in a conductor winding of the electric motor. This first alternating electrical current induces eddy currents in a component of the delivery device, by which the medium can be heated.
Engine system with inferential sensor
An engine system incorporating an engine, one or more sensors, and a controller. The controller may be connected to the one or more sensors and the engine. The one or more sensors may be configured to sense one or more parameters related to operation of the engine. The controller may incorporate an air-path state estimator configured to estimate one or more air-path state parameters in the engine based on values of one or more parameters sensed by the sensors. The controller may have an on-line and an off-line portion, where the on-line portion may incorporate the air-path state estimator and the off-line portion may configure and/or calibrate a model for the air-path state estimator.

Systems and methods of controlling a maximum power output level of an engine-driven power source system
An electric arc generation device includes an internal combustion engine operatively coupled to a generator, an arc generation power supply powered by the generator, an ECU configured to control a maximum power output level of the engine according to one of a low power routine and a high power routine, and a position signal receiver operatively connected to the ECU. The position signal receiver is configured to receive a position signal, generate current position information based on the position signal, and provide the current position information to the ECU. The ECU is configured to compare the current position information to predetermined region data, and automatically switch from one of the high power routine and the low power routine to a different one of the high power routine and the low power routine based on a result of the comparing, to automatically control the maximum power output level of the engine.

CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE
The control device controls a control parameter based on values of operating parameters. The control device is configured to: acquire current values of the operating parameters; calculate, using a model, a probability distribution of an output parameter with respect to a value of the control parameter based on the acquired current values of the operating parameters; and set a target value of the control parameter based on the calculated probability distribution of an output parameter so that the probability of the value of the output parameter becoming equal to greater than a target value is most approached the target probability. The control parameter, operating parameters, and output parameter are parameters different from each other. The model is a model using a Gaussian process which outputs the probability distribution of an output parameter if values of the operating and control parameters are input.

Method of cleaning an exhaust gas recirculation valve
A method of cleaning an EGR valve operatively connected to an exhaust flow from an engine includes determining when cleaning is required, and when cleaning is required, operating the engine in a high temperature mode in which the temperature of exhaust gas exiting the engine is increased while producing a flow of exhaust gas having a low unburnt hydrocarbon content. The method further includes opening the EGR valve to allow hot exhaust gas to flow therethrough so as to remove combustion by-products that are fouling the EGR valve. Furthermore, the method includes producing an estimate of accumulated combustion by-product fouling of the EGR valve. The estimate is then used to determine whether and when to clean the EGR valve.
