With the worsening energy crisis and environment pollution, a higher-efficiency internal combustion engine with lower emissions is crucial for engine manufacturers. Gas fuels like natural gas and hydrogen are currently regarded as promising alternative fuels whose use can resolve both the aforementioned problems, and there industry and engine research centers are exerting much effort to make these gas fuels viable for use in engines. This work was motivated by the desire to gain further insights into the characteristics of the low-pressure gas jet. Experimental gas jet investigation was successfully conducted through the schlieren technique, using a solenoid-valve injector with a maximum injection pressure of 0.8 MPa(absolute pressure) driven by a standard injector driver. Its supply voltage is 12 V, and its opening time, 1.4 ms. The injection pressure has a significant effect on the jet penetration. Also, a higher injection pressure leads to longer jet tip penetration. A high injection pressure leads to a higher jet momentum and higher turbulence energy, which means that the fuel-air mixing rate can be increased by increasing the injection pressure. The research results will be used to support the authors’ ongoing low-pressure injection natural gas engine project.
