DEVICE AND METHOD FOR SIMULATING EFFECT OF TWO-STAGE SUPERCHARGING PRESSURE END OR TURBO END BYPASS ON SPRAY CHARACTERISTICS

摘要

A device and method for simulating the effect of a two-stage supercharging pressure end or a turbo end bypass on spray characteristics. The device comprises a pressure end bypass simulation system, a volume-variable incendiary device, and a spray photographing system. The planar laser induced fluorescence exciplex technique is used to study the effects of a pressure end or a turbo end bypass on atomization, mixture, development history, concentration distribution, and micro characteristics. The technique realistically simulates the effects of the pressure end or the turbo end bypass on spray characteristics when a piston (27) approaches a top dead center, and provides theoretical data support for in-depth study of atomization and mixture improvement after using the pressure or turbo end bypass to achieve efficient clean combustion.
