Experimental Investigation of the Performance and Exhaust Emissions of a Spark-Ignition Engine Operating with Different Proportional Blends of Gasoline and Water Ammonia Solution

Abstract

This paper aims to investigate the impact of utilizing different blends of water ammonia solution (WAS) and gasoline fuel (GF) on the exhaust emission and the engine performance of spark ignition (SI) engine and compare the obtained results with a base case where gasoline is used a sole fuel in the SI engine. The results show that the use of ammonia solution as an addition to gasoline fuel increases the overall thermal efficiency. Moreover, blending GF and Was at a ratio of 75% to 25% respectively achieved a maximum overall efficiency of 38.96% at the maximum load condition. In addition, the specific fuel consumption of the previously mentioned blend is reduced significantly compared to the base case. However, the results displayed that adding WAS leads to an upsurge in the CO, HC, and NOx levels.
