Project description
Ammonia is a fuel of the future due to relatively higher energy density (compared to hydrogen), already existing infrastructure and most importantly no carbon content and can be made as an electro fuel from excess power therefore, CO2 neutral. Application of ammonia is obvious in the marine sector. Since most of these engines are operated on diesel fuels, it is an advantage to apply ammonia according to the CI principle, thereby facilitating the possibility to operate on diesel as well.
We are examining how well ammonia can be used in a compression ignition engine as a green fuel for heavy duty engines. This is done with combustion analysis and exhaust gas measurements. The ammonia is injection through the intake manifold and is ignited by a pilot diesel injection, alternatively with so called ignition improvers. The goal is to reduce the amount of carbon fuel needed for a combustion. To achieve better combustion, intake air heating is applied together with an intake pressure charging system.
