“…Figure 3 shows the BTE of HCNG‐enriched KSOBD20 as a function of injection pressure. The BTE of KSOBD20 was found to be lower than that of pure diesel due to poor fuel atomization, lower heating value, longer ignition delay, and higher kinematic viscosity 15,19,37 . However, the addition of HCNG to KSOBD20 resulted in significant improvement in BTE due to faster flame speed contributing to its higher heating value, improved fuel–air homogeneity, and longer time to form the air–fuel mixture.…”

“…This is due to the fact that hydrogen burns so quickly. Increasing the combustion limit has the effect of reducing the losses caused by the high combustion temperature and heat transfer, which leads to lower BSFC 15,19,29,39,40 . Lower BSFC was also achieved with increased injection pressure.…”

“…Because it contains a greater amount of oxygen and a higher cetane number, biodiesel burns cleaner than diesel. A higher CP is the result of fuel accumulation in the combustion chamber, which is more likely with a longer ignition delay 15,42 …”

“…One disadvantage of biodiesel is that it has a higher viscosity than regular diesel, resulting in poorer atomization and lower energy content per weight, due to the increased oxygen concentration 12,13 . Gaseous, liquid, and solid (i.e., nanoparticle) additives have a great impact on increasing performance due to the improved thermophysical properties of each of these additives 14,15 …”

The objective of the present study is to evaluate the performance, combustion, and emission characteristics of a compression-ignition engine using hydrogen-compressed natural gas (HCNG)-enriched Kusum seed biodiesel blend (KSOBD20). The flow rate of HCNG was set at 5, 10, and 15 liters per minute (lpm), and the injection pressure was varied in the range of 180-240 bar. Brake thermal efficiency (BTE) and brake-specific fuel consumption (BSFC) were improved when HCNG was added to the KSOBD20. Combustion characteristics, namely, cylinder pressure (CP) and net heat release rate (NHRR), were also improved. Emissions of carbon monoxide (CO), hydrocarbons (HC), and smoke were also reduced, with the exception of nitrogen oxides (NO x ). The higher injection pressure (240 bar) had a positive effect on operating characteristics. At an injection pressure of 240 bar, for KSOB20 + 15 lpm HCNG, the highest BTE and the lowest BSFC were found to be 32.09% and 0.227 kg/kWh, respectively. Also, the CP and NHRR were 69.34 bar and 66.04 J/deg. CO, HC, and smoke levels were finally reduced to 0.013%, 47 ppm, and 9%, respectively, with increased NO x levels of 1623 ppm. For optimum results in terms of engine characteristics, the fuel combination

“…As a result of this situation, the engine's characteristics (torque, power, and fuel consumption) and harmful emissions from the exhaust vary significantly. When the studies on the characteristic features of diesel engines and the reduction of harmful exhaust emissions resulting from combustion are examined in the literature, In a study by Jaikumar et al (2021) and in different research on reducing harmful exhaust emissions from diesel engines, the effects were investigated by adding Al2O3 (Aluminium oxide) nanoparticles to the existing B20 biodiesel. It has been observed that there are improvements in combustion characteristics and exhaust emissions with Al2O3 nanoparticles added to biodiesel at a rate of 50ppm.…”

Energy is one of the main factors that ensure the formation of production, development, and economic conditions between countries. Although fossil fuels pose some problems in terms of the environment and human health, they still have great use in meeting the energy demand in the world. Although there are many studies on alternative fuels in today's conditions, diesel engines are more preferred by the countries in heavy-duty vehicles (construction machines, tractors, and combine harvesters) operating in all kinds of commercial and land conditions that are used in transportation. Diesel engines are more preferred in developing countries due to their high torque and low fuel consumption. For this reason, efficiency, operating parameters, and reducing the environmental emissions of diesel engines used in our country are important. Since agriculture is one of the most important fields of activity in our country, in this study, the engine's characteristics and the effects on the exhaust emissions of the rural diesel used in the tractor and the low-sulfur diesel fuel were experimentally investigated. The maximum torque (1400rpm) used during the field plow of the tractor, which is available in Çerkezköy Hattat Tractor Factory R&D Center, and the maximum power (2100rpm) under other driving conditions were tested with both diesel fuels. When the results of the experiments were compared, it was seen that higher torque and power were obtained with the use of low sulfur diesel fuel, while harmful exhaust emissions were lower than rural diesel fuel. However, when the engine's fuel consumption is compared, it has been determined that rural diesel is consumed less than low sulfur diesel.
