摘要
针对机动车尾气排放污染物对环境影响日趋严重的问题,在超声波雾化器中,根据超声波高频振荡的原理,将燃油雾化成了超微粒子,将深度雾化的燃油雾粒与新鲜空气完全混合形成了浓度适当的可燃混合气,并根据不同的转速和工况调节阀门的开度,实现了不同的空燃比,使其在发动机燃烧室中充分燃烧,通过超声波雾化燃油供给系统的测验,取得了可靠的试验结果。研究结果表明,该技术能有效地降低化油器式摩托车尾气排放中HC、CO等污染物的排放量,提高燃油经济性,达到节能减排的目的。
Aiming at increasingly serious problem of motor vehicle exhaust emission pollutants influences on the environment, the principle of ultrasonic high-frequency oscillation was used and the fuel was atomized into ultra fine particles in ultrasonic nebulizer, which is formed the uniform combustible mixture with the fresh air, According to the different speed and working conditions, regulating valve opening was adjusted, to achieve different air-fuel ratio, and then it can full combustion in the engine combustor. By ultrasonic atomizing fuel supply system test, reliable test results were obtained. The results indicate that, it can effectively reduce the carburetor motorcycle exhaust emissions of pollutants (HC, CO) , and improve fuel economy, to achieve the requirements of energy saving and emission reduction.
