“…This shows that the inhibition of inorganic elements on the catalyst also depends on the composition of the reaction gas. In a review of DOC, the effect of SO 2 on the conversion efficiency of NO x affected the passive regeneration efficiency of downstream DPF (Zhang et al 2022d ). However, the proper desulfurization policy can completely restore the performance of the aftertreatment system (Millo et al 2017 ).…”

Diesel particulate filter (DPF) is considered as an effective method to control particulate matter (PM) emissions from diesel engines, which is included in the mandatory installation list by more and more national/regional laws and regulations, such as CHINA VI, Euro VI, and EPA Tier3. Due to the limited capacity of DPF to contain PM, the manufacturer introduced a method of treating deposited PM by oxidation, which is called regeneration. This paper comprehensively summarizes the most advanced regeneration technology, including filter structure, new catalyst formula, accurate soot prediction, safe and reliable regeneration strategy, uncontrolled regeneration and its control methods. In addition, due to the change of working conditions in the regeneration process, the additional emissions during regeneration are discussed in this paper. The DPF is not only the aftertreatment device but also can be combined with diesel oxidation catalyst (DOC), selective catalytic reduction (SCR) and exhaust recirculation (EGR). In addition, the impact of DPF modification on the original system of some old models has been reasonably discussed in order to achieve emission targets.

“…Among these substitute fuels, biodiesel is considered the most promising and attractive alternative fuel because it is sulfur-free, non-toxic, biodegradable, eco-friendly, and more reliable [33]. Many researchers have shown that [34][35][36][37] the physical and chemical properties of biodiesel are very close to those of diesel fuel. Moreover, biodiesel can be applied to diesel engines without changing the engine systems because the combustion and emission characteristics of biodiesel are almost similar to conventional diesel [38].…”

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.

“…The NO x emission is an important aspect in supporting an environmentally friendly fuel alternative. It has been strictly regulated in the Euro VI standard, requiring NO x emission reduction by 95% in heavy-duty diesel engines (Zhang et al 2022a ) since 90% of the NO x emission was known to originate from fossil fuel combustion (70% caused from diesel engines), further highlighting the potential of Fe 2 O 3 as a catalyst (Zhang et al 2022b ). Fe 2 O 3 could be synthesized from iron sand which is an abundant natural resource in Indonesia.…”

The main aim of this work was to develop a heterogeneous Fe 2 O 3 /CaO 2 bifunctional catalyst prepared from iron sand and 3 different CaO 2 sources (CaCO 3 , Ca (OH) 2 , and limestone) using wet impregnation and calcination methods for biodiesel production. The effects of different CaO 2 sources and Fe/Ca ratio in the catalyst were investigated to provide insight into the catalyst character and biodiesel yield. X-ray diffraction, X-ray fluorescence, and scanning electron microscopy analyses were used to characterize the catalyst. CaCO 3 was concluded as the best CaO 2 source, while the best Fe/Ca configuration was found to be 1:4, giving the highest biodiesel yield (97.0401%) with no diglycerides. Greater addition of Fe loading would result in an amorphous structure, and all catalysts were relatively crystalline. Fe was concluded to favor the esterification reaction and biodiesel formation, while CaO 2 was seen to favor the transesterification reaction and fatty acid methyl ester (FAME) formation. The catalyst mechanism was also established in this study, where esterification of free fatty acid (FFA) and glycerol took place on the acid site to produce diglyceride and transesterification of triglyceride by methanol occurred on the basic site.
