Latest Patents
One of Johan's latest patents is an exhaust gas after treatment system. This system includes a diesel particulate filter unit (DPFU) positioned downstream of a diesel engine, along with a selective catalytic reduction (SCR) arrangement in fluid communication with the DPFU. It features a first injector for feeding reducing agent into the exhaust gas, a NOx sensor for providing signals to a NOx coordinator, and temperature sensors for monitoring conditions. The NOx coordinator is designed to switch the diesel engine into high or low NOx modes based on sensor values.
Another significant patent is a controller for electrical machines. This control circuit is designed for a reluctance machine with two movable parts and at least one inductive phase winding. The method involves detecting when a phase winding is in a non-drive mode and causing a test current to flow through the phase winding. This process helps establish a mutual position based on the output of a current sensor.
