“…Because carbon dioxide (CO 2 ) emissions from internal combustion engines are directly proportional to fuel consumption, agricultural machinery is one of the major sources of carbon emissions. However, due to their long-term operation under low-speed and highload conditions [4], their operation in complex and diverse environments, and their wide range, agricultural machinery has been found to emit substantial amounts of pollutants, while their emission control technology remains relatively outdated [5]. In 2021, China's agricultural machinery emitted 205,000 tons of hydrocarbons (HC), 1.671 million tons of nitrogen oxides (NO x ), and 92,000 tons of particulate matter (PM).…”

This study focuses on a small agricultural diesel engine fueled with B20 (20% biodiesel and 80% diesel by volume) blend fuel in a plateau area. The combustion chamber’s structural parameters and fuel injection angle were taken as variables at peak torque conditions. First, a full factorial design was used for experimental design. Second, the back-propagation (BP) neural network was employed to predict the indicated thermal efficiency and the indicated specific NOx emission. Third, the non-dominated sorting genetic algorithm-II (NSGA-II) was utilized to optimize the indicated thermal efficiency and the indicated specific NOx emission. Finally, the technique for order of preference by similarity to ideal solution (TOPSIS) method was applied to obtain optimal solutions, and a three-dimensional numerical simulation was conducted to verify the optimization results. The optimization results indicate that the shape characteristics of the combustion chamber have a certain influence on the engine’s performance. The optimized design significantly reduces NOx emissions, by 22.83%, compared to the original engine, whilst maintaining the engine’s performance.

“…In recent years, research on diesel engines with the aim of increasing efficiency while meeting the performance and emission requirements has been widely explored. It was demonstrated that at higher power density levels with reduced friction resulted in higher engine efficiency [1]. Passenger car diesel engines have already reached specific powers greater than 100 kW/L [2], heavy-duty diesel engines are yet to reach beyond 30 kW/L [3].…”

Mitigating CO2 emissions from long-haul commercial trucking is a major challenge that must be addressed to achieve substantial reductions in greenhouse gas (GHG) emissions from the transportation sector. Extensive recent research and development programs have shown how significant near-term reductions in GHGs from commercial vehicles can be achieved by combining technological advances. This paper reviews progress in technology for engine efficiency improvements, vehicle resistance and drag reductions, and the introduction of hybrid electric powertrains in long-haul trucks. The results of vehicle demonstration projects by major vehicle manufacturers have shown peak brake thermal efficiency of 55% in heavy-duty diesel engines and have demonstrated freight efficiency improvements of 150% relative to a 2009 baseline in North America. These improvements have been achieved by combining multiple incremental improvements in both engine and vehicle technologies. Powertrain electrification through hybridization has been shown to offer some potential reductions in fuel consumption. These potential benefits depend on the vehicle use, the details of the powertrain design, and the duty cycle. To date, most papers have focused on standard drive cycles, leaving a research gap in how hybrid electric powertrains would be designed to minimize fuel consumption over real-world drive cycles, which are essential for a reliable powertrain design. The results of this paper suggest that there is no “one-size-fits-all” solution to reduce the GHGs in long-haul trucking, and a combination of technologies is required to provide an optimum solution for each application.
