摘要
为提升汽油机的燃油经济性和动力性,通过GT-Power搭建进气歧管喷水发动机模型,研究该技术对油耗和扭矩的影响。计算结果表明,进气歧管喷水技术可以降低汽油机爆燃倾向和排气温度,从而通过使用最优点火提前角和理论空燃比使得油耗改善和动力性提升。
To improve economy and dynamic of gasoline engine,a water injection into intake manifold gasoline engine model was set up by GT- Power which can simulate the effect of the technology of water injection into intake manifold on fuel consumption and torque of a gasoline engine.Results show that the knock tendency and exhaust temperature were decreased with the introduction of water injection into intake manifold.And lower fuel consumption and more stronger power were acquired by using an optimal ignition timing and a stoichiometric air-fuel ratio.
