A partnership of Research and Industry entities has developed a fully working hybrid electric vehicle equipped with a 15 kW IC engine fuelled with liquid ammonia as a range extender of the lithium batteries pack on board. The entire vehicle powertrain (ie, the IC engine, the electric generator coupled with the engine, the electric motor, the electronics etc.) has been studied and designed. Regarding the IC engine, as is known, ammonia combustion is characterized by a high activation energy and a low flame velocity, therefore a small amount of hydrogen is requested as igniter and combustion promoter. The necessary amount…
