摘要:
An electric motor particularly suited for a hybrid electric automotive vehicle. The motor includes a stator housing and a rotor having a core and rotatably mounted to the housing by a bearing assembly. An electrical conductor separate from the bearing assembly provides a low impedance electrical conductive path for high frequency radio emissions from the rotor core and to the stator housing thus reducing the transmission of electrical magnetic interference from an output shaft of the rotor.

An integrated premixture chamber is disclosed, for mixing gaseous fuel and air for delivery to a combustion chamber of an internal combustion engine. The integrated premixture chamber includes a mass air flow sensor, a throttle valve and position sensor, a fuel shut-off valve, a gas flow sensor and a fuel metering valve having discharge outlets downstream of the mass air flow sensor to provide more accurate metering. The integrated premixture chamber is controlled by an electronic unit separate from the engine's control unit.
摘要:
A smart mass gas flow sensor is having a housing with a bore through which a gas flows in which a sensor in the housing generates an analog signal proportional to the mass gas flow through the housing bore. A digital processor digitally processes the analog signal from the sensor and generates a substantially linear output signal representative of the mass gas flow through the housing bore.
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.
