Effect of a Compression Ratio Increase and High-Flow-Rate Injection on the Combustion Characteristics of an Ammonia Direct Injection Spark-Ignited Engine

Journal of Marine Science and Engineering
Despite efforts to use ammonia as a fuel, there remain problems with low combustion speeds and high unburned ammonia (NH3) emissions. Therefore, methods to compensate for slow combustion speeds and stabilize combustion have been studied.
