“…Inferior properties and CV of MSBD and H 2 blends cause less pressure than diesel. , However, the H 2 induction to MSBD enhances the peak pressure. Supplying H 2 to BD improves combustion and aids in higher peak pressure. − Improved deflagration pace, ignition energy, and heating-value of H 2 lowers the ignition delay, enhances combustion, and increases peak pressure of MSBD . Peak pressure further increases for MSBD-H 2 (10 lpm) than MSBD-H 2 (5 lpm).…”

This study aims to examine the ignition pattern of CI engines run by nonedible mango seed biodiesel (MSBD). This work is also aimed to improve the ignition pattern of diesel engines by inducing hydrogen as a dual fuel in the intake manifold at various mass flow rates of 5 and 10 L per minute (lpm). Various parameters were calculated with varying intake hydrogen rates with MSBD and compared with diesel. Results concluded that the hydrogen supply at 10 lpm improved peak pressure by 3.22 bar, heat release rate (HRR) by 5.47 J/°C A, and brake thermal efficiency (BTE) by 3.4% of MSBD. Further, hydrogen supply also reduced overall HC by 0.36 g/ kWh, CO by 3.9 g/kWh, and smoke emission by 3.8 Bosch smoke unit (BSU) at all brake mean effective pressures (BMEPs) from neat MSBD with a 3.3 g/kWh increase in NO. Further, this research work reveals that hydrogen addition at 10 lpm with MSBD shall improve the ignition patterns of a diesel engine.

“…The comparative analysis between the results was made between (no-EGR, it = -20), (25% EGR, it = -20), (25% EGR, it = -25). Previous studies [15,[19][20][21][22][23] have shown that advances in injection timing led to increased peak pressure, thermal efficiency, and NOx emissions. Therefore, it would be evident that the injection advance catches up with reducing pressure caused by EGR.…”

Recently, there is an increasing interest in the pyrolysis of waste plastic into usable fuel as a friendly environment method for waste plastic disposal. The existing literature from various studies stated that the major problem related to the use of WPO in diesel engines is the high NOx emissions level. This paper aims to remedy this problem by suggesting the best EGR percentage with the advanced optimum injection timing. Primary, 5 EGR percentage fractions are considered: 0%, 5%, 15%, 20% and 25% percent. The results showed that 25% is the best percentage regarding emissions. However, a signiﬁcant reduction in mean in-cylinder pressure, temperature, and heat release rate was depicted with the EGR fraction increase. Injection timing is advanced to recoup the decrease in performance. The results showed that 25% of EGR and advanced injection timing by 5 degrees would be better for performances and emissions of DI diesel engine while running with waste plastic oil as an alternative fuel.

“…Because greenhouse gas emissions are rising, raising the blending ratio from 10% to 15% boosts vehicle emissions, favouring mechanical efficiency. It is crucial to adhere to the strict emission regulations (Bharat stage-6) and we need to locate a suitable candidate for the diesel blend [20]. Heavy trucks and buses frequently utilize diesel engines, making them potential candidates for diesel fuel [10] [6].…”

“…Using an oxygenated mixture of high carbon alcohol, this study aims to reduce these emissions. It also offers a comparative investigation of the effects of WPO addition on Single cylinder diesel engines ( Depoures, Dillikannan, and Kaliyaperumal 2020) [20]. The cylinder head's pressure transducer was installed there, and the NOx was measured and recorded using a charge amplifier (Depoures, Dillikannan, and Kaliyaperumal 2020).…”

According to this study, the combined NOx and Smoke Opacity of waste plastic oil and N-Octanol are higher than diesel fuel. To find the optimal combination, waste plastic oil was blended with diesel. The best blend (10%, 20%, and 30%) was contrasted with a blend of diesel and N-Octanol. Five load variations have been tested using a stationary, single-cylinder Kirloskar engine with a bore and stroke of 85 and 110 mm. The G-power was estimated using the G-Power tool v-3.1.9.7, and the sample size was 60. According to the tested experiments, the best blend, D50W30O20, had a NOx level of 2098 ppm for pure diesel and 2145 ppm for waste plastic oil. For neat diesel, the smoke opacity was 32.1. For waste plastic oil, 57.6, and the optimum blend, D50WPO40O10, 41.3. The group’s significance level of 0.000 (p0.05) indicates a meaningful difference. Within the investigation parameters, D50WPO30O20 had a NOx rating 82% higher than diesel and 47% higher for the waste plastic oil blend. When compared to diesel, the smoke opacity of the waste plastic oil blend was 16% higher, and the smoke opacity of D50WPO20O30 was 9% higher.
