点火和喷氢正时对增压直喷氢内燃机性能、燃烧和排放特性影响
Effects ofignition and injection timing on performance, combustion and emissions characteristics of a turbo-charged direct injection hydrogen engine
氢气具备可再生、零碳排放和良好的经济效益，其作为内燃机的替代燃料在“双碳”背景下具有重要战略意义。在利用氢能的利用中，直喷氢内燃机(DI-HICE)具有高动力性、高经济性和零碳排放等优势。本文主要研究了点火正时和喷射正时对涡轮增压直喷氢内燃机的性能、燃烧和排放特性的影响。结果表明，通过调整点火正时，推迟燃烧重心，降低气缸温度，最多可以减少92%的氮氧化物排放，而涡轮增压器可以弥补延迟点火造成的部分能量损失；同时，推迟喷射正时可以使氢内燃机的有效热…查看全部>>
Hydrogen shows promise as an alternative fuel for combustion engines due to its renewability, zero carbon emissions, and favorable economic efficiency. In the process of utilizing hydrogen, the direct-injection (DI) hydrogen internal combustion engine (HICE) has been proven to generate significant power with high thermal efficiency and a low risk of abnormal combustion. This study investigates the effects of the ignition timing and injection timing influence…查看全部>>
