“…By using hydrogen gas with biodiesel results improved the rate of BTE which was agreed by various research work 48,51 . Paparao and Murugan 52 investigate the diesel engine was tested using hydrogen, jatropha biodiesel, and diesel fuel in dual fuel mode. The results showed a 5.8% increase for the hydrogen and biodiesel fuel mix when compared with diesel fuel while the engine was at full load.…”

“…This is because the waste‐fired oil biodiesel molecule has a higher cetane number, which makes it easier for the biodiesel to burn quickly during the premixed combustion period 54 . These research publications were in agreement that by test optimizing the rate of hydrogen, biodiesel, and diesel on a dual‐fuel diesel engine, a lower rate of BSEC range could be achieved in comparison with diesel fuel 52,55 . The dual‐fuel diesel engine was evaluated by Yaliwal et al 56 using hydrogen, dairy product biodiesel, and conventional diesel fuel under a variety of load circumstances.…”

Using nonedible waste frying oil (WFO) as biodiesel and hydrogen in the mix composition may partly replace significant quantities of diesel fuel and help reduce fossil fuel reliance. The combination of diesel fuel, waste‐fired biodiesel, and hydrogen gas can improve the performance, combustion, and emissions of single‐fuel and dual‐fuel diesel engines. This may lead to a novel alternative fuel mix pattern and modification for diesel engines, which is the research gap. Although there has been some research on waste‐fired biodiesel and hydrogen gas‐powered dual‐fuel engines with the goal of partly replacing fossil fuels to a larger degree, there has been very little progress in this area. As a result, the current research effort focuses on using diesel fuel (100%, 30%, and 60%), waste‐fired biodiesel (at 100%, 70%, and 40%), and hydrogen gas as fuel sources (5 and 10 liters per minute [LPM]). According to the current experiment, it was perceived in both dual‐fuel and single‐fuel modes. Under duel‐fuel mode, the engine results for WFOB70D30 + H10 fuel blend had higher 4.2% (brake thermal efficiency [BTE]), 19.72% (oxides of nitrogen [NOx]), and 9.09% (ignition delay [ID]) with a minimal range of (in‐cylinder pressure, MFB, volumetric efficiency and heat release rate [HRR]) and a dropped rate of 4.34% (brake‐specific energy consumption [BSEC]), 33.33% (carbon monoxide [CO]), 39.28% (hydrocarbons [HC]), 9.43% (smoke), and 6.97% (combustion duration [CD]) related to diesel fuel at peak load. However, single‐fuel powered diesel engines provide minimal performance for the WFOB40D60 fuel blend with (11.32% lower BTE and 2.04% higher BSEC) and minimal rate of combustion (lower cylinder pressure, 2.12% minimal CD, 14.72% higher ID, minimal HRR combustion, volumetric efficiency, and MFB). Emitted fewer emissions (9.09% less CO, 4.87% less HC, 0.92% higher NOx, and 1.69% more smoke) than diesel fuel at peak load. Therefore, it was concluded that adding 10 LPM of hydrogen gas to the biodiesel under a dual‐fuel condition leads to better combustion, better performance, and less pollution than the single‐fuel mode of operation.

Low heat rejection (LHR) diesel engines help increase engine performance and reduce engine emissions, but they increase air‐polluting nitrogen oxide (NOx) emissions. Different types of antioxidants or additives can be added to fuels to reduce NOx emissions and improve engine performance. In this investigation, N,N′‐diphenyl‐p‐phenylenediamine (DPPD) is used as an antioxidant. Different concentrations of DPPD namely, 500, 1000, 1500, and 2000 ppm are mixed with Jatropha Methyl Ester (JME)‐diesel blend (JME20), and the fuels are tested in an engine fitted with a TBC piston. The piston crown is coated using a mixture of Yttria‐stabilized zirconia (YSZ) and cerium oxide (CeO2) with a coating thickness of 0.3 mm. The novelty of this research work is the comprehensive assessment of the engine characteristics of an LHR diesel engine run on a synthetic antioxidant‐doped biodiesel‐diesel blend. Results indicate that the peak heat release rate (HRR) and the peak cylinder pressure are lesser by about 5.6% and 5.1% for JME20B4, respectively, at maximum engine load, in the coated engine (CE). The nitric oxide (NO), hydrocarbon (HC), and carbon monoxide (CO) emissions are reduced by about 6.5%, 17.4%, and 34.6%, respectively, at full load for the JME20B4 fueled LHR diesel engine. Smoke opacity decreases up to 15.3% in the coated diesel engine fueled with JME20B4 at full load.
