Abstract: A system and method for self-adjusting engine performance parameters in response to fuel quality variations that includes an exhaust sensor for measuring a level of carbon dioxide present in an exhaust manifold, at least one of a knock sensor and a cylinder pressure transducer for determining a location of peak pressure and a centroid, respectively, a controller in communication with the exhaust sensor and the at least one of the knock sensor and the cylinder pressure transducer, the controller correlating a methane number of the fuel used by the engine to a brake specific carbon dioxide value calculated using the level of carbon dioxide measured by the exhaust sensor and the at least one of the centroid and the location of peak pressure, and an adjusting mechanism, wherein the adjusting mechanism adjusts an engine performance parameter based on the determined methane number.

Abstract: A system is provided comprising an engine having a first cylinder bank and a second cylinder bank disposed in a VEE configuration, a first compressor configured to compress fluid to a first pressure, a first cooler coupled to the first compressor, the first cooler receiving the compressed fluid from the first compressor and cooling the compressed fluid, a second compressor coupled to the first cooler, the second compressor being configured to receive cooled, compressed fluid from the first cooler and compress the cooled, compressed fluid to a second pressure that is higher than the first pressure, and a second cooler coupled to the second compressor, the second cooler receiving the compressed fluid from the second compressor and cooling the compressed fluid for introduction into the pair of cylinder banks. The first compressor, the first cooler, the second compressor and the second cooler are disposed within the VEE.
