Integrierter Luft-/Kraftstoffverhältnis-Sensor mit Vorwärtsregelung für Brenngasmotoren

摘要

An integrated air/fuel sensor is disclosed for use with a gaseous fuel internal combustion engine. The sensor includes a housing having a mass air flow sensor which provides an output signal representative of the mass of air flow through the mass air flow sensor. Similarly, a mass gas sensor is also contained in the housing which provides an output signal representative of the mass of gas flow through the mass gas flow sensor. The integrated air/fuel sensor is mounted to the air and fuel supply system for the engine upstream from the internal combustion engine. The output signal from both flow sensors are provided as input signals to a circuit which calculates the air/fuel ratio to the engine and provides an output signal representative thereof to the fuel management system for the engine.
