旋转发动机由于其狭长的燃烧室设计，可能会遇到高油耗和高排放的问题。氢的低点火能量和高火焰速度有助于改善旋转发动机的燃烧。研制了一种装有汽油和氢气喷射器的汽油旋转发动机，研究了氢混合汽油旋转发动机的燃烧和排放特性。发动机以3000转/分的转速运行，歧管绝对压力为37.5千帕，化学计量过量空气比。火花定时被设置为25°CA前的上死点。这台发动机首先用纯汽油作燃料，然后与氢混合。进气氢体积分数由0%逐渐提高到5.2%。结果表明：掺氢后，燃烧压力、制动平均有效压力、气缸温度和热效率均有显著提高；随着加氢量的增加，峰值压力曲柄角增大。富氢能有效缩短火焰的发展和传播周期。当进气氢气体积分数由0%提高到5.2%时，HC排放量减少44.8%，CO和co2排放量也有所减少。
The rotary engines may encounter high fuel consumption and emissions due to its narrow and long combustion chamber design. The low ignition energy and high flame speed of hydrogen may help improve the combustion of rotary engines. In this paper, a gasoline rotary engine equipped with gasoline and hydrogen injectors was developed to investigate the combustion and emissions of hydrogen-blended gasoline rotary engines. The engine was run at 3000 rpm and a manifolds absolute pressure of 37.5 kPa with the stoichiometric excess air ratio. The spark timing was set to be 25°CA before the top dead center. The engine was first fueled with the pure gasoline and then blended with the hydrogen. The hydrogen volume fractions in the intake were gradually increased from 0% to 5.2%. The results showed that the combustion pressure, brake mean effective pressure, cylinder temperature and thermal efficiency were simultaneously increased after the hydrogen blending. The crank angle of peak pressure was advanced with the hydrogen addition. The hydrogen enrichment was effective on reducing flame development and propagation periods. HC emissions were reduced by 44.8% when the hydrogen volume fraction in the intake was raised from 0% to 5.2%, CO and CO2emissions were also reduced after the hydrogen blending.
