“…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]. In addition, compared to diesel, biodiesel has a higher cetane number [39], no aromatics, and 10-11% oxygen content [40,41]. These characteristics of biodiesel fuel can reduce CO, HC, and PM emissions in exhaust gases.…”

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.

With the improvement and development of micro-mechanical manufacturing technology, people can produce an increasing variety of micro-electromechanical systems in recent years, such as micro-satellite thrusters, micro-sensors, micro-aircrafts, micro-medical devices, micro-pumps, and micro-motors. At present, these micro-mechatronic systems are driven by traditional energy power systems, but these traditional energy power systems have such disadvantages as short endurance time, large size, and low energy density. Therefore, efforts were made to study micro-energy dynamical systems with small size, light gravity, high density and energy, and long duration so as to provide continuous and reliable power for these systems. In general, the micro-thermal photoelectric system not only has a simple structure, but also no moving parts. The micro-thermal photoelectric system is a micro-energy power system with good application prospects at present. However, as one of the most important structural components of micro-thermal photoelectric systems, the microburner, is the key to realize the conversion of fuel chemical energy to electric energy in micro-thermal photoelectric system. The studies of how to improve the flame stability and combustion efficiency are very necessary and interesting. Thus, some methods to improve the performance of micro-burners were introduced and summarized systematically, hoping to bring some convenience to researchers in the field.

“…Among potentially implementable technologies, the selective catalytic reduction of NO x using ammonia as reducing agent (NH 3 -SCR) is a well established DeNO x technique because of its high efficiency and desired selectivity of N 2 . 1 Several Cubased zeolite catalysts, such as Cu/ZSM-5 and Cu/beta, perform high NH 3 -SCR activities, [2][3][4][5] but the narrow activity window and weak hydrothermal stability impede their commercial applications. The stringent emission regulations lead to the development of aertreatment systems combining Diesel Particulate Filters (DPF) with highly stable zeolitebased SCR catalysts, capable of withstanding active DPF regeneration conditions.…”
