“…Rajak and Nashine et al [231] investigated the effects of different spirulina microalgae biodiesel (SMB) ratios with diesel fuel on engine performance and emissions in a fourcylinder, four-stroke, water-cooled diesel engine. The CO 2 emissions with different engine loads are shown in Figure 24.…”

“…They explained that oxygenated fuel or added oxygen in the combustion process provides the combustion with more oxygen aiming to oxidize and convert CO into CO 2 . Rajak et al [231] investigated a renewable and sustainable microalgae biodiesel (MAB) in a single-cylinder, compression ignition engine with different engine loads and compression ratios. The CO 2 emissions with different engine loads and compression ratios are shown in Figure 26a-d.…”

“…They indicated that the nearly 13% oxygen content in biodiesel structure results in better combustion in the cylinder; thus, smoke emissions were decreased by about 35.7% compared to diesel. Rajak et al [231] investigated the effects of different CRs and loads on the engine performance and emission characteristics of a single-cylinder diesel engine. The smoke emission results for different engine loads and different CRs showed that the smoke emissions increased at low loads due to the poor atomization caused by the higher viscosity of biodiesel, thus increasing smoke emissions.…”

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.

“…However, the use of preheated method combined with EGR could reduce NO x emissions and improve the thermal efficiency of the engine. Rajak et al 29 studied the emission characteristics of a diesel engine fueled with microalgae biodiesel. The results showed that the PM and NO x emissions decreased with the adoption of microalgae biodiesel compared to pure diesel.…”

Oxygen-containing alternative fuels have excellent potential to improve diesel fuel economy and reduce particulate matter (PM) emissions. In this study, a novel mixed dialkyl oxalate (mDAO) as an additive was applied to substitute conventional diesel to investigate the effects of mDAO on the combustion and emission characteristics of a high-pressure common-rail diesel engine. The research conducted suggested that the peak pressure rise rate in the main injection stage and the peak in-cylinder pressure presented the rising tendency with the increased mass fraction of mDAO at most test conditions. With the addition of mDAO, the in-cylinder temperature ( T ) and brake thermal efficiency (BTE) were higher than that of pure diesel. When the mass fraction of mDAO in the mDAO/diesel blend was 30%, the improvement of BTE was most obvious. The ignition delay was prolonged as the mass fraction of mDAO was increased due to the lower cetane number of the mDAO. In addition, adding mDAO into diesel had an effective impact on the reduction of PM emissions, while the nitrogen oxide (NO x ) emissions deteriorated. These results indicate that mDAO is a great potential diesel alternative fuel.
