Utilization of renewable and sustainable diesel/methanol/n-butanol (DMB) blends for reducing the engine emissions in a diesel engine with different pre-injection strategies

Dongli Tan et al.

Summary: In the face of the severe energy and environmental crisis, using alternative fuels, specifically biomass fuels, is an effective way to alleviate energy shortage and environmental pollution. This study investigated the parameters of a medium-speed marine diesel engine fueled with diesel/methanol/n-butanol blended fuel, focusing on the effects of pre-injection on combustion, performance, and emission parameters. Results showed that advancing pre-injection timing and increasing pre-injection fuel mass ratio increased cylinder pressure, reduced emissions, but increased fuel consumption. An optimal combination of pre-injection timing and fuel mass ratio was determined through orthogonal design. This study provides a theoretical foundation for optimizing fuel injection strategies coupled with the combustion process of oxygenated fuels.
