Nevertheless, ammonia presents challenges such as low laminar flame speed, high minimum ignition energy, and high auto-ignition temperature. To address these issues, the combustion performance of ammonia engines is enhanced through the use of gasoline as a promoter. This study examined the combustion and emissions characteristics of a four-cylinder spark ignition engine operating on an ammonia-gasoline dual-fuel, with a compression ratio of 11.5:1 under different operation conditions. The influences of ammonia substitution rate, spark timing, and engine load were investigated. The findings revealed that raising the ammonia substitution rate from 0 % to 80 % significantly affected how the flame kernel forms, slowing down the flame propagation speed. Increasing the ammonia substitution rate lowers in-cylinder combustion temperature, reducing heat transfer loss to coolants and improving thermal efficiency by 3.2 %. In comparison to pure gasoline, the combustion of the ammonia-gasoline mixture produced higher NOx emissions, which was primarily from fuel-NOx source. Meanwhile, emissions of unburned ammonia gradually increased, while CO and HC emissions decreased. The main source of N<sub>2</sub>O emissions was the low-temperature oxidation pathway of ammonia, and a higher ammonia substitution rate or a delay in spark timing resulted in higher N<sub>2</sub>O emissions. At higher engine loads, the ammonia-gasoline engine exhibited more stable operation and improved thermal efficiency. Nevertheless, these benefits came at the cost of increased emissions of unburned NH<sub>3</sub>, HC, and CO, while the emissions of N<sub>2</sub>O and NOx were reduced.</div></div>","PeriodicalId":337,"journal":{"name":"International Journal of Hydrogen Energy","volume":"122 ","pages":"Pages 348-358"},"PeriodicalIF":8.1,"publicationDate":"2025-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143783972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
