Latest Patents

Andreas Kärcher holds a patent titled "Method for cylinder equalization in an internal combustion engine operating by direct injection." This patent describes a method where the values for the speed of the crankshaft are corrected using an acausal mean-value filter. The change in the kinetic energy of the crankshaft during the expansion interval of a cylinder is calculated from these dynamically corrected speed values. This calculation is then referred to the maximum fuel quantity that can be fed in this interval. The resulting dimensionless residue serves as a measure of whether too much or too little fuel has been injected into the cylinder. Correction terms derived from these residues allow for adaptation in the overall region of the characteristic diagram, especially during speed transitions.
