Effects of pressure atomization using a jet engine fuel injector with wall impingement on the atomization characteristics have been investigated. In the present study, combustion test using the injector was conducted. Effects of nozzle number N on combustion characteristics were investigated. It is shown that when equivalence ratio φ=0.60〜1.00, SMD is from 69 to 233 μm in nozzle number N=6. It is shown that when equivalence ratio φ=0.60〜1.00, SMD is from 73 to 213 μm in nozzle number N=8. Atomization mode is Air-Blasting Atomization mode in both nozzle number N=6 and N=8. It is also shown that when equivalence ratio φ=0.60〜0.65, EI(NO_x) decreases with the increase in SAID. It is also shown that when equivalence ratio φ=0.70〜1.00, EI(NO_x) decreases in nozzle number N=6 comparing to nozzle number N=8.
