Abstract A SYSTEM FOR CONTROLLING A COMBUSTION QUALITY OF A FUEL, E.G., OCTANE OR CETANE VALUE, WHEREIN THE DETONATION INTENSITY OR TIME LAG OF A TEST FUEL POWERING A STANDARD TEST ENGINE IS COMPARED TO A REFERENCE VALUE TO GENERATE AN ERROR SIGNAL. THE COMPRESSION RATIO OF THE ENGINE IS ADJUSTED IN RESPONSE TO A FUNCTION OF THE ERROR SIGNAL TO MAINTAIN A PREDETERMINED CONDITION OF DDTONATION INTENSITY OR TIME LAG, AND THE AMOUNT OF ADJUSTMENT OF THE COMPRESSION RATIO PROVIDES A REPRESENTATION OF THE COMBUSTION QUALITY OF THE FUEL. THE SYSTEM ALSO INCLUDES MEANS FOR CONTROLLING A PROCESS OF BLENDING THE TEST FUEL TO A PREDETERMINED SPECIFICIATION IN RESPONSE TO A SIGNAL WHICH IS A FUNCTION OF THE AMOUNT OF ADJUSTMENT OF THE COMPRESSION RATIO.
