摘要

乙醇驱动的插电式混合动力汽车为减少轻型运输中的碳排放提供了一种可持续的选择。本研究通过提高压缩比、米勒循环和废气再循环来优化宝马i3的增程发动机，使其适用于含水乙醇。车辆模拟和测试表明，与混合汽油相比，该系统的制动油耗降低了10.5%，燃油效率提高了4%。与汽油增程剂相比，在大多数循环中，使用乙醇可使车辆油耗降低20%以上，总体能耗降低10%，但由于乙醇的能量密度较低，里程损失为5%。尽管如此，乙醇的快速加油能力比电池电动汽车更有优势。这些发现强调了乙醇动力增程器作为降低排放同时减轻里程焦虑的实用解决方案。

Enhancing efficiency of ethanol-powered range extenders in the BMW i3: A simulation-based optimization approach

Ethanol-powered range-extended plug-in hybrid electric vehicles offer a sustainable alternative to reduce carbon emissions in light-duty transport. This study optimizes a BMW i3's range-extender engine for hydrous ethanol by increasing compression ratio, applying a Miller cycle, and using exhaust gas recirculation. Vehicle simulations and testing show a brake-specific fuel consumption reduction of up to 10.5 %, with a 4 % fuel efficiency gain over gasoline blends. Ethanol use decreased vehicle fuel consumption by over 20 % in most cycles and reduced overall energy consumption by 10 % compared to the gasoline range extender, though with a 5 % range loss due to ethanol's lower energy density. Despite this, ethanol's rapid refuelling capability presents an advantage over battery-electric vehicles. These findings highlight ethanol-powered range extenders as a practical solution to lower emissions while mitigating range anxiety.
