Ammonia Combustion in a Spark-Ignition Engine Supported with Dimethyl Ether

Energies, 2023
This paper presents the results of experimental tests with a spark-ignition engine powered using ammonia and DME (dimethyl ether). The tests were carried out on a CFR (cooperative fuel research) engine with a compression ratio of 10 and a rotational ...
