Abstract
As a result of a large number of diseases due to environmental pollution resulting from emissions and fast energy depletion. Many researchers resorted methods to produce a mixture that can be used as fuel and fight these issues. In this work, a mini review was concluded through previous studies to highlight and investigate the effect of using water ammonia solution on the characteristics of IC engines with special focus on gasoline engines. The main findings showed decreased engine performance because ammonia has a lower calorific value and energy density. also, most of the previous contributions highlighted a significant reduction in CO2 and CO emissions for all loads. Using ammonia solution increased NOx emissions slightly.
