“…Exhaust gas recirculation (EGR) systems are another potential solution that can reduce the formation of hazardous pollutants such as nitrogen oxides (NO x ). EGR systems can be incorporated into engine designs so that they are compatible with biofuels [177][178][179]. The use of Diesel Oxidation Catalyst (DOC) in the emission control system was effective and applying DOC to the diesel engine's exhaust pipe resulted in a 90% decrease in HC and an 85% reduction in CO [180].…”

The environmental sustainability of agricultural and industrial vehicles, as well as of the transportation sector, represents one of the most critical challenges to the sustainable development of a nation. In recent decades, compression-ignition engines have been widely used in on-road and off-road vehicles due to their better fuel economy, autonomy, compactness, and mechanical performance (spec. the high torque values). Due to the consistent environmental impact of fossil fuels, scientists are searching for alternative energy sources while preserving the beneficial features of diesel engines. The utilization of blends of diesel fuel, biodiesel, and bioethanol fuel (referred to as “ternary blends”) is among the most promising solutions for replacing fossil fuels in the near term, allowing, at the same time, us to continue using existing vehicles until new technologies are developed, consolidated and adapted to the agricultural and industrial sector. These ternary blends can lower exhaust emissions without creating major problems for existing fuel-feeding systems, typically designed for low-viscosity fossil fuels. One of the concerns in using liquid biofuels, specifically biodiesel, is the high chemical affinity with conventional and bio-based lubricants, so the main parameters of lubricants can vary significantly after a long operation of the engine. The comprehensive literature review presented in this article delves into the technical challenges, the main research pathways, and the potential solutions associated with the utilization of biofuels. Additionally, it investigates the emerging application of nanoparticles as additives in lubricants and biofuels, highlighting their valuable potential. This study also discusses the potential implementation of bio-ethanol in ternary blends, offering a promising avenue for reducing reliance on fossil fuels while maintaining engine efficiency.

This study uses AVL FIRE 2020 R1 software for simulation and experimental verification to deeply analyze the impact of combustion chamber geometry and biodiesel on diesel engine performance at different injection timings. The study found that: With the advancement of injection timing, the indicated fuel consumption rate, cylinder pressure and NOx emissions of the two combustion systems increased, while the indicated thermal efficiency, temperature and Soot emissions decreased accordingly; The blending of low calorific value biodiesel will increase the indicated fuel consumption rate of the two combustion systems, but at the same time it can effectively reduce NOx and Soot emissions; The T: Turbocharger, C: Charger air cooling, D: Diesel particle filter (TCD) combustion system improves the utilization rate of cylinder air due to its unique combustion chamber geometry, thereby improving combustion performance. Compared with the Omega combustion system, the indicated thermal efficiency of the TCD combustion system increased by 6.16% to 8.38% and the indicated fuel consumption rate decreased by 5.80% to 7.73% when burning four types of fuel. In addition, the in‐cylinder pressure and temperature increased, and it performed better in reducing Soot emissions. The research results show that the TCD combustion system can effectively improve the combustion and emission performance of diesel engines, provide data support for the development of diesel engine combustion systems and the combustion of oxygen‐containing fuels in plateau environments, and provide an important reference for energy conservation and emission reduction.
