Abstract: A method for controlling a vehicle semi-active suspension system comprising at least one suspension, providing for: detecting vehicle dynamic quantities during the vehicle ride; using the detected dynamic quantities, determining an index of ride comfort and an index of roadholding; applying a weight factor to the index of ride comfort and to the index of roadholding and, based on a Sky Hook control model, determining a target damping force characteristics for the at least one suspension of the suspension system; controlling the at least one suspension to put the respective damping force characteristics in accordance with the calculated target damping force characteristics. The weight factor is calculated dynamically during the vehicle ride, by means of a fuzzy calculation on the detected vehicle dynamic quantities.

Abstract: A method of and an arrangement for burning a liquid or gaseous fuel in a combustion chamber of an internal combustion engine. A method of and an arrangement for burning a liquid or gaseous fuel in the presence of air or another oxidant and by the use of water in a combustion chamber (12) of an internal combustion engine, especially a reciprocating or rotary piston-type engine. To reduce the fuel consumption and the emission of harmful substances and to increase the efficiency when low-octane fuels, especially regular gasoline or acetylene, are used, water is injected during one or several selected phases, in particular during the entire operation, in an operation-dependent quantity direct into the combustion chamber (12) in such a way that a progressive "primary combustion" of fuel/air just below the critical "knock" temperature (T.sub.c) occurs which initiates a "secondary combustion" of the admixed water at any point of combustion.
