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 diameter D on combustion characteristics were investigated. It is shown that when equivalence ratio φ = 0.60〜1.00, SMD is from 40 to 213 μm. Atomization mode is Air-Blasting Atomization mode. It is also shown that when equivalence ratio φ = 0.60〜0.80, El(NO_x) decreases with the increase in SMD. It is also shown that when equivalence ratio φ = 0.80〜1.00, El(NO_x) is almost constant regardless of nozzle diameter D.
