Summary: The global demand for cleaner and greener sources of energy is increasing, and developed countries are shifting towards non-conventional/renewable/green sources of energy. They are also trying to involve developing countries in the fight against global warming and pollution. Hydrogen, with its high calorific value, abundance, and cleaner nature, is a suitable choice as a cleaner energy source.

Summary: This study focuses on the efficient utilization of waste cooking oils and alternative vegetable oils in engine fuel. Experimental results show that the blend of WCO and neat diesel (ND) in a dual-fuel diesel engine, labeled as WCOB50, has a negligible reduction in brake thermal efficiency (BTE) compared to pure diesel. Additionally, the impact of hydrogen induction on tailpipe exhaust emissions from a CI engine using WCOB fuel is examined.

Summary: The demand for energy is increasing every year, while the use of fossil fuels has led to a rise in carbon dioxide levels and global warming. Therefore, alternatives such as biomass and waste-derived fuels are being explored. In this study, waste lubrication oil was pyrolyzed to obtain a diesel-like fuel with high conversion efficiency, and the blend of this fuel with diesel showed improved engine performance with reduced emissions. Additionally, the introduction of gaseous hydrogen further enhanced the thermal efficiency of the diesel engine while reducing HC, CO, and smoke emissions, although NOx emissions increased. This study demonstrates the suitability of the combination of pyrolyzed waste lubricant and hydrogen as a fuel for unmodified diesel engines.

Summary: Currently, most ships still rely on fossil fuels as the main source for marine engines. However, diesel as a fuel for marine engines is no longer sufficient to meet the economic requirements of shipping and emission restrictions imposed by regulations. This research examined the viability of employing hydrogen-carrying fuel ammonia (NH3) in marine engines to develop a low-carbon combustion technology, to address the carbon emission problem of marine diesel engines.

Summary: This study investigates the feasibility of an ammonia/diesel dual-fuel engine in reducing greenhouse gas emissions while maintaining diesel-like efficiency. Results show that increasing the ammonia energy fraction reduces nitrogen oxide emissions but increases nitrous oxide emissions, resulting in higher overall greenhouse gas emissions compared to diesel-only combustion. Advancing the start of diesel injection helps reduce nitrous oxide and overall greenhouse gas emissions while achieving diesel-like thermal efficiency.

Summary: The limited supply and negative environmental impacts of fossil fuels have driven the search for alternative energy sources. The use of hydrogen as a clean energy source in internal combustion engines can reduce emissions and provide an alternative to petroleum-derived fuels. This study highlights the importance of hydrogen ratio and combustion chamber design in engine performance and emissions, suggesting a hydrogen energy ratio between 5% and 20% and considering combustion characteristics when designing the chamber. It serves as a valuable resource for researchers working on dual fuel mode in compression ignition engines.
