South Korean researchers have successfully road-tested a dual fuel passenger car that runs on a mixture of ammonia and gasoline. It is called the AmVeh and was developed by members of the Ammonia Research Group at the Korean Institute for Energy Research (KIER).
Ammonia-gasoline dual fuel, and pure ammonia engines
The prototype vehicle uses a fuel ratio of 70% ammonia to 30% gasoline to power a spark ignition engine. As ammonia contains no carbon, this fuel ratio results in a corresponding 70% reduction in carbon dioxide emissions, compared to pure gasoline.
The AmVeh team is now focused on improving the fuel system and the exhaust after-treatment system. Once these are optimized, they aim to develop an engine system that runs on ammonia alone, without any support from gasoline. The emissions from this carbon-free vehicle would be pure water and nitrogen.
The engine system demonstrated in the AmVeh would enable conventional vehicles to be converted to ammonia fuel. Continue reading
Spark-Ignited Ammonia Engines and Gensets
The Hydrogen Engine Center (HEC) is developing ammonia-hydrogen and ammonia-propane spark ignited engines, with the goal of achieving a super-efficient 100% ammonia engine in the near future. Continue reading
