Simulation of Fuel Economy of Gasoline-Ethanol-Ammonia Tertiary Fuel Blends for a Series Hybrid Electric Vehicle

By on September 23, 2014
With the depletion of petroleum resources around the world, a need to have cleaner and fuel efficient automotive technologies and alternative fuel sources has become prominent. Hybrid electric vehicles and sustainable energy sources have gained a high momentum in fulfilling this requirement. To satisfy both needs ammonia, which has been used for a long period of time as a sustainable and carbon free transport fuel can be combined with hybrid electric vehicles. Ammonia when blended with gasoline can be used as an alternate fuel to power existing internal combustion engines. Such blends similar to ethanol-gasoline fuel blends would provide a…

Further Evolution of an Ammonia Fuelled Range Extender for Hybrid Vehicles

By and on September 22, 2014
In a previous research the possibility to run a small 4-stroke twin-cylinder SI engine of 505 cm3 with ammonia plus hydrogen was demonstrated. Ammonia and hydrogen tanks were utilized to feed the engine while, apart, the suitability of a custom-designed catalytic reactor to produce hydrogen from ammonia with the required flow rate was verified as well. The experimental activity confirmed the need to increase combustion velocity by adding hydrogen to air-ammonia mixture, with energy ratios that mainly depend on load and less on engine speed. The minimum hydrogen to ammonia energy ratio was found below 6% at full load and…
