摘要： A system for sensing and controlling a fuel gas composition may include a plurality of micro-sensors (251) mounted in a single chamber (250), with each of the micro-sensors (251) being configured to sense a characteristic of a mixture of gaseous fuel introduced into the chamber (250). The system may also include a plurality of heating elements, with each of the heating elements being associated with one of the plurality of micro-sensors (251), and the plurality of heating elements being configured to simultaneously increase a temperature of the mixture of gaseous fuel at each of the plurality of micro-sensors (251) to a different temperature level at each of the micro-sensors (251). The system may also include a microprocessor (254) configured to determine a thermodynamic property of the mixture of gaseous fuel at the different temperature levels at each of the micro-sensors (251) as a function of the characteristic sensed by each micro-sensor, correlate the thermodynamic property to a fuel gas composition of the mixture of gaseous fuel, and control an amount of at least one constituent in the mixture of gaseous fuel as a function of the fuel gas composition determined by the correlation.

摘要： A control system (114) is provided for use with an engine (12). The control system may have a sensing element (58) in fluid communication with a flow of unknown mixture of gaseous fuel supplied to the engine. The sensing element may be configured to sense a thermodynamic property of the unknown mixture of gaseous fuel. The control system may also have a heating element (60) configured to increase a temperature of the unknown mixture of gaseous fuel at the sensing element to multiple different temperature levels, and a microprocessor (62) configured to determine a fuel parameter of the unknown mixture of gaseous fuel as a function of the thermodynamic property sensed at the multiple different temperature levels. The control system may further have a controller (56) in communication with the microprocessor and configured to selectively adjust a control parameter of the engine based on the fuel parameter.
