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
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
