摘要
针对氢燃料在转子机方面的应用进行了综述,旨在探索转子机的可持续发展之路。凭借火焰速度快和淬火距离短的特点,氢气能够改善转子机由于燃烧室狭长、面容比大而导致的不完全燃烧,降低油耗与排放;由于进气、做功与排气处于不同工作腔且无进/排气门结构,转子机更能避免氢点火能量低而引起的早燃和回火现象,从而有效提升热效率,改善发动机做功能力。
Hydrogen is the most promising clean energy in the 21st century.To meet more stringent emission regulations and achieve carbon peaking and neutrality,hydrogen-powered engines have gained keen academic interest in recent years.With a compact structure,high power-to-weight ratio,high-speed performance,low vibration and noise,rotary engines have a huge market potentials in UAVs,extended-range electric vehicles,and other fields.This paper reviews hydrogen powered Wankel rotary engine,aiming to seek the sustainable development of rotary engines.Existing research shows with the fast flame speed and short quenching distance,hydrogen improves the incomplete combustion caused by the narrow combustion chamber and the large surface-volume ratio of rotary engines,thus reducing fuel consumption and pollutant emissions.Since the intake,expansion and exhaust strokes are in different working chambers,and there is no intake/exhaust valve structure,the rotary engine is better at avoiding the auto-ignition and backfire caused by low hydrogen ignition energy,thus effectively improving the thermal efficiency and enhancing the working capacity of the engine.
