项目摘要

The proposed project will integrate Libertine's 'intelliGEN' Opposed Free Piston development platform together with subcontractor MAHLE Powertrain's Flexible ECU (MFE) within an engine test cell at MAHLE Powertrain's facility in Northampton, to demonstrate a first-of-a kind variable compression ratio combustion development engine for renewable fuels. The first demonstration fuel will be bioethanol, a low carbon fuel that can be produced from renewable resources including agricultural wastes and residues. During phase 1 Libertine will make plans with MAHLE Powertrain and prospective OEM clients for phase 2, to build a prototype and test it in real world scenarios. In a free piston engine, the crankshaft is replaced by high performance linear electrical machines permitting engine manufacturers to dispense with the crankshaft mechanism in future internal combustion engines. In its place, Libertine's linear electric machines will allow electronic piston motion control to deliver real-time variable compression ratio, providing optimum combustion conditions in every combustion event -- whether during cold-starts, peak power or peak efficiency operating modes, even if the fuel blend in the tank changes with every fill. The variable compression ratio and non-sinusoidal piston motion capabilities of Free Piston Engines allow cleaner and more efficient utilisation of renewable and synthetic low carbon fuels owing to the combustion characteristics of several of these new fuels. Libertine's intelliGEN Opposed Free Piston development engine systems provide the means for OEMs to develop new products to make full use of synthetic, low carbon and renewable fuels. These products will be essential for the decarbonisation of 'hard to electrify' transport applications including light and medium duty commercial vehicles, for a proportion of passenger automotive market where vehicle use and recharging constraints are a barrier to electrification, and for a larger range of distributed power generation applications.

拟议中的项目将在位于北安普顿的MAHLE动力总成工厂的发动机测试单元中将Libertine的‘intelliGEN’反自由活塞开发平台与分包商MAHLE动力总成的灵活ECU(MFE)集成在一起，以展示第一款用于可再生燃料的变压比燃烧开发发动机。第一个示范燃料将是生物乙醇，这是一种可以从包括农业废物和残渣在内的可再生资源中生产的低碳燃料。在第一阶段，Libertle将与MAHLE动力总成和潜在的OEM客户一起制定第二阶段的计划，以建立一个原型，并在现实世界的场景中进行测试。在自由活塞发动机中，曲轴被高性能的直线电机取代，允许发动机制造商在未来的内燃机中省去曲轴机构。Libertine的直线电机将取代它，使电子活塞运动控制提供实时可变压缩比，在每个燃烧事件中提供最佳燃烧条件--无论是在冷启动、峰值功率还是峰值效率运行模式下，即使油箱中的燃料混合每次都会发生变化。由于几种新燃料的燃烧特性，自由活塞发动机的可变压缩比和非正弦活塞运动能力允许更清洁和更有效地利用可再生和合成低碳燃料。Libertine的intelliGEN反自由活塞开发发动机系统为原始设备制造商提供了开发新产品的手段，以充分利用合成、低碳和可再生燃料。这些产品对于包括轻型和中型商用车在内的“难以电气化”的交通应用的脱碳，对于车辆使用和充电限制是电气化障碍的乘用车市场的一部分，以及对于更广泛的分布式发电应用来说，都将是必不可少的。
