【Abstract】 A new adaptive drive circuit was designed to control the natural gas nozzle by using the output pulse width modulation(PWM) signal. The high pressure conduction low conservation was realized, the problem was solved that the hot nozzle was too large by the traditional driving way, the stability and the service life of the nozzle were enhanced. The simulation experiment was carried out based on AMESim software. The calculated flow rate was compared with the experimental flow rate, and the validity of the adaptive driving way was verified.更多还原
