The AmVeh – an ammonia fueled car from South Korea

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
AmVeh, Korean Institute for Energy ResearchThe 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 Marangoni Toyota GT86 Eco Explorer

A new sports car that uses ammonia fuel is touring the motor shows of Europe.

The Marangoni Toyota GT-86 Eco-Explorer is an ammonia / gasoline hybrid, designed by Italian tyre-maker Marangoni, which claims 111 miles of zero-emission driving from one tank of ammonia.

The Eco Explorer was first shown at the Geneva Motor Show (March 7-17) in Switzerland, and then at the Gadget Show Live in the UK (April 3-7) and Top Marques in Monaco (April 18-21). Its next stop is Tuning World Bodensee in Friedrichshafen, Germany (May 9-12).

From Marangoni’s Eco Explorer microsite, which features extensive photographs and an atmospheric video: Continue reading
