“…The substitution of air that would normally reach the combustion chamber with the substitute fuel is the cause of the decrease in VE that occurs at high flow rates of hydrogen and HHO gas. Yilmaz et al found the same trend of a decrease in VE in their experimental analysis, in which they injected HHO gas into the intake manifold of a CI engine, 6 the same trend of a decrease in VE was found. This resulted in the loss of VE.…”

Investigation on combustion and emission characteristics of hydrogen‐enriched dual‐fuel engine operated under waste frying oil biodiesel

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.

“…Similar techniques to those found in literature and described in Sections 2.3 and 2.6 are employed in this work for the salient operating parameters of the system (production plant, commercial engine) with regards to the various relevant criteria of reduced fuel cost, enhanced engine efficiency, and the consideration of surrounding environmental characteristics. In MOGA, it is possible to optimise the biodiesel blends for various constraints of performance, economy, and emission parameters [33]. The optimisation helps choose the correct quantity of biodiesel fuel in conjunction with injection parameters such as timing and pressure.…”

In this study, the thermal analysis of an aluminum piston coated with MgOZrO2 to create a thermal barrier with the COMSOL multiphysics program and the changes in exhaust gas temperature, fuel consumption, and engine torque values obtained as a result of engine test experiments were examined. For this purpose, the MgOZrO2 coated and uncoated piston engine was started with biodiesel and 5% water + 15% ethanol doped biodiesel fuel at engine speeds of 1000 rpm, 1500 rpm, 2000 rpm, and 2500 rpm. In the thermal analysis results obtained in the COMSOL, it was found that the temperature values increased in the upper regions of the coated pistons. Likewise, in engine experiments, increased exhaust gas temperature and engine torque showed a tendency to decrease fuel consumption values. It has been observed that the data obtained in the analysis in the COMSOL program are in parallel with the results of the engine experiments.
