Abstract

The problem of global warming and environmentally polluting emissions has become the call of the times. To solve this problem, the trend to change or share new types of fuel has become a new way to solve this problem. One of the most promising types of fuel in the future is ammonia, as it is a carbon-free fuel, unlike traditional fossil fuels. Because of the danger of using ammonia as a gas, it was safer to use ammonia as a liquid. In this study, ammonia hydroxide was used as a proportion with diesel fuel in a PCCI diesel engine. The diesel engine is a single-cylinder, four-stroke engine. Ammonia hydroxide fuel with a ratio of 33% ammonia-water by volume was used with diesel fuel. The experiment was carried out with ammonia hydroxide ratios of 2.5%, 5%, 7.5%, and 10%, respectively. The results of emissions, thermal efficiency (BTE), fuel consumption (BSFC) and exhaust temperatures were compared. It was concluded that using ammonia hydroxide ratios to diesel led to an increase in thermal efficiency by 23.5% compared to diesel only by 20.5%, and fuel consumption was also reduced. 391.083g/Kw.h compared to diesel is only 455.56 g/Kw.h. As a result of the presence of ammonia hydroxide, exhaust temperatures are lower than when using diesel only. Therefore, this study discusses with practical experience the effect of using ammonia hydroxide with diesel on the performance and efficiency of the engine and fuel emissions characteristics.
