With a prescribed voltage waveform imposed on DCP, the inner solenoid valve is first activated to start the compression stage for expelling air bubble. After that, the valve is immediately closed to build up the high pressure inside DCP for forcing gasoline passing through the nozzle. In response to the shutdown of electrical power, DCP restores to its original rest state in the end of the ejection stage. The gasoline liquid jet with adequate inertia momentum would overcome the liquid surface tension and viscous force for accomplishing the droplet injection. The present study has successfully constructed the test and measurement platform to determine the baseline mass flowrate characteristics for a DCP device. To establish a useful database for the future development of the injection technology for motorcycles, this work is also extended to explore the variations of injection performance at different settings of environmental pressure, temperature, and voltage of battery. This Study sets up to control program by the LabVIEW, which can controls every experiment parameter control condition of DCP fuel injection, such as operative frequency of the fuel injection, the operative time of the fuel injection sprays, etc. It uses CCD to pick a fluent situation of the fuel injection that can observes the difference flows of key parameter of the voltage and vacuum pressure to DCP injection and traditional fuel injection.
