Diesel engines are popular in transport, agriculture, and industry due to their fuel economy and lower CO2 emissions. However, conventional high-temperature diesel combustion systems have higher NOx and PM emissions. Current emission control methods are expensive and reduce fuel economy. Biodiesel is a promising alternative due to its renewability, cleaner-burning, and carbon-neutral nature. It can be produced from various sources, including waste vegetable oil, making it a flexible fuel choice. The study aims to develop a multi-mode and flexi-fuel strategy-based diesel engine that operates with waste resources and blends to achieve high efficiency and clean combustion. The engine will be modified to run in a multi-mode and flexi-fuel strategy, switching between biodiesel-diesel blend operated conventional combustion and biodiesel-diesel and plastic pyrolysis oil-gasoline-like fuels operated dual fuel LTC mode. This approach aims to address the shortcomings of biodiesel and RCCI combustion simultaneously in terms of high NOx, high unburned hydrocarbon (HC), and carbon monoxide emissions.
