This program aims at improving the understanding of the sooting behavior of different biomass-derived fuels to support the development of cleaner energy carriers. Actually, soot is one of the major pollutants generated in combustion processes and one of the main contributors to anthropogenic aerosols. To limit its production with the view to meet actual and future regulations, source reduction remains a key option particularly considered by engine manufacturers. A thorough understanding of the physicochemical mechanisms involved in the formation of polycyclic aromatic hydrocarbons (PAHs) and soot is still required however (especially in the case of biofuels) to improve the predictive character of the computational codes used to design combustion devices. The purpose of the present program is therefore to provide insightful findings regarding the ability of different molecules to act as soot suppressors with the view to identify the must-have fuel properties necessary for the mid- to long-term commercialization of environmentally-friendly substitutes to petroleum-derived fuels. To do so, the present proposal which associates laboratory scale experiments and engine tests is composed of 3 main objectives summarized as follows:

该计划旨在增进对不同生物质衍生燃料的烟灰行为的了解，以支持清洁能源载体的开发。实际上，烟尘是燃烧过程中产生的主要污染物之一，也是人为气溶胶的主要来源之一。为了限制其生产以满足实际和未来的法规，减少来源仍然是发动机制造商特别考虑的一个关键选择。然而，仍然需要彻底了解多环芳烃 (PAH) 和烟灰形成所涉及的物理化学机制（特别是在生物燃料的情况下），以提高用于设计燃烧装置的计算代码的预测特性。因此，本计划的目的是提供关于不同分子作为烟灰抑制剂的能力的深刻见解，以期确定环保替代品中长期商业化所必需的燃料特性。石油衍生燃料。为此，本提案将实验室规模实验和发动机测试结合起来，由 3 个主要目标组成，总结如下：
