    • PROBLEM TO BE SOLVED: To provide a system and a method for providing fuel having a desired calorie content to a combustion engine in a range of a series of operation levels. SOLUTION: The system mixes first fuel from a first fuel supply pipe with second fuel from a second fuel supply pipe at a mixing point 26 to create mixed fuel having a first calorie content. A control valve 24 is located in the second fuel supply pipe upstream of the mixing point 26. A process system downstream of the mixing point 26 treats the mixed fuel to generate treated mixed fuel having a second calorie content. A first control signal is reflective of the first calorie content of the mixed fuel. A second control signal is reflective of the second calorie content of the trreated mixed fuel. A third control signal is reflective of the operating level of the combustion engine. A control device 40 connected to the control valve 24 drives the control valve 24 based on the first, second, and third control signals. COPYRIGHT: (C)2011,JPO&INPIT
