“…The vaporization and sensible water heat are considered possible reasons resulting in the reduction in local temperature for adiabatic flame and NO x formation. A similar trend was also observed by Krishania et al [242] used 20% spirulina, waste cooking, and animal fats blended with biodiesel fuel in an auto-ignition diesel engine with different compression ratios. The results shown in Table 8 indicate that the biodiesel blend reduces NO x emissions compared to diesel due to lower combustion temperature.…”

Due to the increasing air pollution from diesel engines and the shortage of conventional fossil fuels, many experimental and numerical types of research have been carried out and published in the literature over the past few decades to find a new, sustainable, and alternative fuels. Biodiesel is an appropriate alternate solution for diesel engines because it is renewable, non-toxic, and eco-friendly. According to the European Academies Science Advisory Council, biodiesel evolution is broadly classified into four generations. This paper provides a comprehensive review of the production, properties, combustion, performance, and emission characteristics of diesel engines using different generations of biodiesel as an alternative fuel to replace fossil-based diesel and summarizes the primary feedstocks and properties of different generations of biodiesel compared with diesel. The general impression is that the use of different generations of biodiesel decreased 30% CO, 50% HC, and 70% smoke emissions compared with diesel. Engine performance is slightly decreased by an average of 3.13%, 89.56%, and 11.98% for higher density, viscosity, and cetane, respectively, while having a 7.96% lower heating value compared with diesel. A certain ratio of biodiesel as fuel instead of fossil diesel combined with advanced after-treatment technology is the main trend of future diesel engine development.

Favourable efficiency of diesel engines makes them the most abundant type of internal combustion engines. However, diesel engines are also primary sources of particulate matter (PM) and nitrogen oxides (NOX) emissions formed as a result of the combustion process. There are many variables to affect the performance of diesel engine. One of them is injection pressure. Combustion process has a crucial effect on emission formation of diesel engines and this process is highly affected by fuel atomization. Injectors are one of the most important components of diesel engines that control the atomization of fuel. Today's modern injectors provide high injection pressures to improve fuel atomization. To reduce exhaust emissions and fuel consumption, the effect of high-pressure fuel injection was investigated in fourcylinder engines numerically. Increased injection pressure improves smoke and fuel consumption, especially at low and medium speeds. However, some variables can be adversely affected by pressure increases. In this study, variables affecting engine performance were observed at different injection pressures for 500-800 bar and 800-1000 bar, and the results were shared.

“…Based on the fuel properties, WCO biodiesel is expected to have slower atomization and air–fuel mixing process than diesel. Krishania et al showed that the spray droplet size of biodiesel was 20% larger than that of diesel due to its higher viscosity and surface tension . However, reductions in HC, CO, and PM emissions with biodiesel were exhibited in earlier studies due to the promotion of the oxidation process by oxygen content in the fuel. , …”

Biodiesel PCI Combustion for Performance and Emission Improvement in a Compression Ignition Engine

Low-temperature combustion has the potential to reduce nitrogen oxides (NO x ) and particulate matter (PM) emissions; however, it faces the challenge of high level of hydrocarbon (HC) and carbon monoxide (CO) emissions. Application of oxygenated fuel such as biodiesel to LTC has gained interest to overcome this drawback. This study aims to provide a comprehensive understanding of the influence of biodiesel on premixed compression ignition (PCI) in a single-cylinder compression ignition engine. A series of engine tests were carried out at an engine speed of 1200 rev/min with two injection pressures (800 bar and 1600 bar), two injection timings (25 and 5 crank angle degree (CAD) before top dead center (bTDC)), and four exhaust gas recirculation (EGR) rates (0–30%). Engine performance results showed that fuel consumption with PCI combustion was higher than that with conventional diesel combustion (CDC) due to the advanced combustion phase. The lower heating value of biodiesel resulted in approximately 10% higher fuel consumption than diesel regardless of test conditions. In terms of emissions, PCI combustion indicated higher carbon CO and HC emissions because of liquid fuel flow in squish areas with early injection timing supported by a Lagrangian spray simulation. However, the application of biodiesel in PCI combustion was beneficial to suppress CO and HC emissions while maintaining low levels of NO x and PM emissions compared to CDC condition. Especially, the PN emission under PCI biodiesel condition was 1/10 of CDC. Soot morphology by TEM imaging showed a smaller primary particle diameter with biodiesel, attributed to enhanced soot oxidation.
