Abstract: Disclosed are an aperture-adjustable mixed-flow nozzle and its atomization method. The nozzle includes a cylindrical shell with an airflow chamber and a mixed-flow chamber. The airflow chamber is connected to an air inlet, and the mixed-flow chamber is connected to a liquid inlet. An nozzle is provided at the bottom wall of the mixed-flow chamber on the cylindrical shell. The cylindrical shell allows airflow from the airflow chamber to enter the mixed-flow chamber through an adjusting shaft. A swirling flow path is disposed around the outer periphery of the adjusting shaft, and a gas path for connecting the airflow chamber and the mixed-flow chamber is disposed inside the adjusting shaft. By adjusting the nozzle aperture size, not only is the problem of nozzle blockage resolved, but it also allows for control of atomization effects and spray field conditions, making it more effective for complex dust-producing environments on-site.

Abstract: A method and a system for controlling an air-fuel ratio for a gas engine are provided. Current outlet pressure of the nozzle is calculated based on current pressure in an intake pipe and a current rotational speed, without detecting the outlet pressure of the nozzle by a sensor. A fluid state of the gas can be determined based on a ratio of the current outlet pressure to the current inlet pressure of the nozzle collected by a sensor, such that a flow rate characteristic corresponding to the fluid state can be selected to calculate power-on duration for the nozzle, so as to set the air-fuel ratio based on the power-on duration. The power-on duration can be calculated based on flow rate characteristics of the gas in respective fluid states, thereby achieving an air-fuel ratio with high accuracy.
