English
This chapter reviews renewable oxygenated fuels—ethanol, biodiesel, and DME—as pathways to decarbonize compression ignition engines. It compares how molecular structure and physicochemical properties affect ignition delay, heat release, thermal efficiency, fuel consumption, and regulated and non-regulated emissions. Practical barriers to scale-up such as miscibility, storage stability, lubricity, and infrastructure needs are also examined, spanning incremental substitution to transformative approaches.

📄 Abstract（原文）
Renewable oxygenated fuels play an important role in decarbonizing compression ignition engines by providing pathways that leverage existing diesel technologies while reducing carbon emissions. Among the most significant options are ethanol, biodiesel, and dimethyl ether (DME), which represent different levels of technological transition. Ethanol is a low-cost oxygenated additive but presents challenges related to ignition quality, fuel stability, and energy density. Biodiesel is a mature renewable alternative with broad compatibility in current diesel fleets and infrastructure. DME, in contrast, offers exceptionally high cetane numbers and near-zero soot combustion, although its adoption requires substantial modifications to fuel systems and storage infrastructure. This chapter examines how the molecular structure and physicochemical properties of these fuels affect key engine performance and combustion parameters, including ignition delay, evaporation characteristics, heat release behavior, brake thermal efficiency, and specific fuel consumption. Special attention is given to their influence on regulated emissions, such as nitrogen oxides and particulate matter, as well as non-regulated pollutants, including carbonyl compounds and ultrafine particles. In addition to combustion performance, practical aspects relevant to large-scale implementation are discussed, such as miscibility, storage stability, lubricity, fuel handling requirements, and infrastructure needs. Together, ethanol, biodiesel, and DME illustrate the range of strategies available for diesel engine decarbonization, from incremental fuel substitution to more transformative technological approaches.
