Latest Patents

One of Johan Larsson's latest patents is a method for controlling a turbocharger system with a pressurized gas tank connected to an exhaust manifold of a combustion engine. This innovative method involves determining a NOx parameter that indicates emissions from the exhaust after-treatment system. By injecting pressurized gas from the tank to drive the turbocharger turbine based on the NOx parameter, the system can effectively manage emissions, ensuring that a determined NOx parameter above a predefined threshold triggers the injection of pressurized gas.

Another significant patent by Larsson is a method for controlling a vehicle equipped with an internal combustion engine and an automatic transmission. This method focuses on managing the engine's rotational speed in response to a decrease in demanded torque. By ensuring that the engine does not drop below a specific rotational speed threshold, the method prevents unnecessary gear downshifts, thereby enhancing the driving experience.
