Abstract:

In this paper is presented a comparison between hydrogen-ammonia (70/30 H2/NH), hydrogen (100%) and gasoline fuels in internal combustion engine. Performance and emission parameters have been experimentally analyzed for different engine speed and ignition timings. Tests have carried out on Lombardini engine which is four stroke cycle, two cylinder spark ignition engine with a bore × stroke of 72x62 mm and a compression ratio of 10.7:1. Emission values (CO, HC and NO) and performance values (SFC, torque, power) have been investigated. An advantage of ammonia and hydrogen is that they do not contain carbon, eliminating emissions of carbon oxides from the engine
