“…At a 100% load condition, the EGT of diesel fuel, B20, B20 + H2 (6L/m), B20 + H2 (6L/m) + 10% EGR, and B20 + H2 (6L/m) + 20% EGR were found to be 185 °C, 195 °C, 240 °C, 230 °C, and 220 °C, respectively. The faster and better fuel combustion that led to the temperature reaching its peak can be blamed for the enhanced EGT [ 39 ]. The reduced EGT after EGR operation compared to B20 + H2 (6L/m) was attributed to inefficient fuel combustion caused by the greater specific heat and a lack of enough oxygen in the intake charge.…”

Rapid depletion of fossil fuels required the development of alternate and sustainable fuel sources that could replace conventional fuel while having no negative environmental impact. Combining hydrogen induction with biodiesel ensures strict emission standards and lowers energy consumption compared to conventional fuels. In this study, the performance, emissions, and combustion of a CI engine for Syzygiumcumini (B20) were assessed and compared to diesel fuel while using a fixed amount of hydrogen flow rate (6L/m). Throughout the experiment, an exhaust gas recirculation (EGR) technology of 10% and 20% and a constant engine speed of 1500 rpm at varying engine load circumstances were used. When hydrogen is added to B20, it decrease the emissions of carbon monoxide (CO), unburned hydrocarbons (UHC), brake thermal efficiency (BTE), and brake specific energy consumption (BSEC). At maximum load, the use of the EGR system decreased the exhaust gas temperature (EGT) by 13.4% and nitrogen oxide (NOX) emission by 25%, but it had a negative impact on BTE, BSEC, as well as other emission parameters including CO and UHC. Therefore, using hydrogen in dual fuel mode in a CI engine enhances performance and lowers exhaust emissions, while using the EGR approach reduces NOX emissions.

“…The EGT increased with an increase in engine load in all operating modes. This is due to the rise in total energy intake during high load, which causes an increase in fuel consumption (Naima et al., 2021). Additionally, it was discovered that increasing the percentage of EGR resulted in a decrease in EGT.…”

The disposal of waste plastic has intensified into a massive environmental crisis. A sound disposal technology may be extremely expensive or complex in operation. As a result, experts are investigating alternative methods of recycling waste plastic. Waste plastic oils (WPO) are gaining interest as a replacement for petroleum-based fuels since they can deliver substantial performance while having a low environmental impact. The goal of this research is to look into the use of WPO in a retarded timing (RT) engine with a partially stabilized zirconium combustion chamber surface (PSZ). In addition, Exhaust Gas Recirculation (EGR) augmentation was used to realize WPO performance fully. With 20% EGR, the engine's thermal efficiency increased by 6.33%, along with the significant reduction of NOx. However, CO, HC, and smoke particle emissions increased by 4.56%, 5.76%, and 3.54%. More research on the sustainability aspects of the WPO is required before considering it as a fuel for the transportation sector.

“…The amount of oxygen available for combustion was decreased by the presence of exhaust gases in the intake mixture, even though exhaust gases are primarily made up of high-specific-heat gases such as carbon dioxide, nitrogen, etc. The increase in the specific heat caused by the addition of exhaust gases to the intake mixture lowers the flame temperature [21][22][23]. In addition, the effect of FeCl 3 and diethyl ether (DEE) as additives in the fuel was also investigated to reduce the emissions.…”

Experimental Evaluation of Performance and Combustion Characteristics of Blended Plastic Pyrolysis Oil in Enhanced Diesel Engine

Plastic waste is the largest volume of waste and the most discarded, and it has a direct negative impact on the environment. Therefore, the pyrolysis oil process is an essential and sustainable solution to reduce plastic waste accumulation. However, the plastic pyrolysis fuel performance in diesel engines is reduced due to its lower cetane number. Diesel and pyrolysis oil were blended in ratios of 90:10 (BP10), 80:20 (BP20), 70:30 (BP30), 60:40 (BP40), and 50:50 (BP50) and applied in a single-cylinder diesel engine to investigate the engine performance and exhaust emission. The long ignition delay, thermal efficiency drops, and emission growth were found regarding the higher blended fuel ratios. BP30 was selected to evaluate the performance and combustion characteristics of blended plastic pyrolysis oil and diesel fuel blends by enhancing an unmodified engine using low hydrogen additions (1000 ppm) and advanced timing adjustment. The hydrogen injected into the intake manifold, along with the advanced fuel injection timing (−16.5 CA°BTDC), affected engine performance and emissions (CO, HC, and NO) at 1500 rpm under 25%, 50%, and 75% of the maximum load compared with diesel fuel. The results showed that the hydrogen addition was very positive for both engine performance and emission reduction, as the expanded flammability of the hydrogen promoted a wide range of combustion within the cylinder, whereas the advanced injection timing achieved improved engine performance but produced higher emissions compared to B7 at all engine loads.
