Latest Patents
One of Hälleberg's latest patents is a method and system for diagnosing unintended fuelling from fuel injectors of an engine. This innovative method allows for the diagnosis of unintended fuelling during engine operation by determining the pressure in the fuel accumulator tank and assessing whether the actual amount of fuel provided exceeds the demanded amount. Additionally, it involves monitoring the temperature associated with the oxidation catalyst and the air/fuel ratio to confirm unintended fuelling based on specific conditions.
Another significant patent is a method for determining the bulk modulus of fuels in a combustion engine's fuel system. This method involves determining the volume of the high-pressure system by supplying a fuel with a known bulk modulus and controlling the high-pressure pump to perform a pump stroke with the volume closed. The determined volume is then used to assess the bulk modulus of other fuels.
