Due to their availability and environmental concerns, waste plastic, which contains a lot of hydrocarbons with high calorific value, makes suitable alternative fuels. Pyrolysis oil from discarded plastics can fuel diesel engines without modification. The performance, combustion, and emissions of waste plastic oil bio-diesel blend were tested on a single-cylinder, CRDi vehicle research engine with an open ECU. The test varied engine speed (1500, 2000, 2500 rpm) and load (low, medium, full). Waste plastic oil (WPO) blended with pure diesel fuel in 10%, 20%, and 30% volumes and compared to diesel. Engine speeds increased cylinder pressure and brake thermal efficiency. The findings demonstrate that the thermal efficiency of all waste plastic oil blends is lower compared to diesel across all loading conditions. Specifically, at full load, the peak cylinder pressure, heat release, combustion duration, and ignition delay were higher for plastic oil and its blends compared to diesel. The engine running on waste plastic oil experienced a roughly 6% increase in peak pressure but exhibited lower thermal efficiency. These test results highlight the significant impact of the fuel's physical properties on combustion characteristics. In addition, it is observed that increase in Nitrogen oxides (NOx) emission and low brake specific fuel consumption with respect to the speed. The utilization of WPO with diesel up to 20% in the blend can be used in diesel engines with a slight increase in emission of Carbon monoxide (CO) at higher loads.

Renewable and cleaner diesel engine fuel has received a lot of attention recently as a result of the depletion of fossil resources. In light of this, biodiesel has proven to be a viable substitute for diesel fuel. The finest B20 Jamun blends were combined with three different types of nano-additives to create Syzygium cumini (Jamun) biodiesel, which was tested in a naturally aspirated diesel engine. Global researchers are increasingly developing novel nano-additives, recognizing them as a promising and effective approach for enhancing fuel properties and engine performance. This technology was combined with different biodiesels. Also included in this chapter is an examination of a test engine using three distinct nano-additives: titanium dioxide (TiO2), zirconium oxide (ZrO2), and cerium oxide (CeO2). These additives were combined to create the best blends of Syzygium cumini (B20), and the results were evaluated based on factors such as performance, combustion, and output emissions. Additionally, a proposal is made to further improve the construction of a realistic and economically feasible nanoparticle addition for diesel and biodiesel fuel.
