摘要： A method and apparatus for controlling a solenoid-actuated charcoal canister purge valve to control the flow of purge fuel that is supplied via the purge valve to a cylinder of an internal combustion engine. The method includes generating a preselected input duty cycle for use in energizing the solenoid-actuated purge valve that is registered by a microcontroller. The solenoid-actuated purge valve is energized using the input duty cycle to generate an output duty cycle from a current driver in operable communication with the microcontroller. The output duty cycle dictates the quantity of purge fuel flow to the cylinder by controlling the active period of energizing the solenoid. A feedback voltage (Vfb) from the solenoid-actuated purge valve is measured, wherein the feedback voltage (Vfb) corresponds to a feedback duty cycle (DCfb). The microcontroller calculates an error between the input duty cycle (Idc) and the feedback duty cycle (DCfb) and generates a compensated output duty cycle to the current driver based on the error calculated to compensate any deviation. The compensated output duty cycle compensates for any deviation from a linear relationship between the input duty cycle (Idc) and feedback voltage (Vfb), wherein Vfb corresponds to a flow of purge fuel.

摘要： A pressure transducer assembly mountable in an interior of a tire for sensing a pressure of a fluid in the tire comprising: a sensor housing having a first compartment in fluid communication with the fluid; a second compartment separated from the first compartment by a divider slideably engaged with and removable from the sensor housing; the divider having disposed thereon a circuitry; the circuitry including a pressure transducer in fluid communication with the first compartment, and a transmission circuit coupled to the pressure transducer for transmitting a signal responsive to the internal pressure to a remote location; a removable power source coupled to the circuitry contained entirely within the second compartment; and a cover sealingly engaged with the housing and the divider such that the second compartment is not in fluid communication with the first compartment. A method of sensing the tire pressure and communicating a signal responsive to the tire pressure to an external receiver located in a remote location is also disclosed.
