不同引燃方式下氨掺氢燃烧对发动机的性能影响
Effect of ammonia blended with hydrogen combustion on diesel engine performance under different ignition modes
摘要
Abstract
Ammonia is a promising zero-carbon fuel.However,when its amount is too large,it will escape rapidly.Therefore,ammonia is mixed with a certain proportion of hydrogen to promote the combustion reaction in the cylin-der,and the pilot diesel is replaced by hydrogen to achieve zero-carbon combustion.Herein,the effect of ammonia and hydrogen on engine combustion and emission performance during diesel ignition and hydrogen ignition is pre-liminarily simulated using CONVERGE software.During diesel ignition—when the hydrogen blending ratio is 30%,compared with 0—the in-cylinder detonation pressure and power increase,fuel consumption rate decreases,ammo-nia escape proportion decreases,NOx emission increases,CO2 emission increases by 0%,and soot and HC emis-sions are improved.During hydrogen ignition,when the hydrogen mixing ratio is 30%,compared with 0%,the in-cylinder detonation pressure and power increase,fuel consumption rate decreases,ammonia escape ratio decreases,NOx emission increases by fourfold,and CO2 emission increases by 0%before and after combustion.After the hy-drogen mixing combustion,the overall performance of the diesel engine is improved.As for the diesel ignition mode,the in-cylinder direct injection of ammonia mixed with 30%hydrogen is a better scheme to achieve net-zero-carbon emission.Results provide a basis for the practicality of ammonia fuel and can be used to guide experimental research.关键词
