ALEXANDRIA, Va., Sept. 23 -- United States Patent no. 12,422,338, issued on Sept. 23, was assigned to DAF Trucks N.V. (Eindhoven, Netherlands).
"Engine pre turbine pressure monitoring system" was invented by Luc Hubertus Josephina Worms (Eindhoven, Netherlands) and Maarten Robertus Ingmar Nieuwenhuijze (Vlijmen, Netherlands).
According to the abstract* released by the U.S. Patent & Trademark Office: "A pressure monitor is arranged to calculate a pre-turbine pressure. The monitor is programmed to derive a normalized turbine speed, normalized for a pre turbine temperature, and a heat capacity ratio of exhaust gas before the turbine as first inputs; determine a turbine power normalizing factor as a second input; determine an actual turbocomp...
