**Industry challenge**Decarbonisation of heavy-duty vehicles is challenging due to demands on powertrain cost-performance, operational availability, design life and reliability, which are yet to be wholly met by any existing low carbon powertrain approach, such as fuel cells, battery electric or hybrid architectures.Heavy-duty applications are much more sensitive to the specific operation-critical and cost-of-ownership characteristics of these technologies, creating uncertainty for UK-based OEMs trying to determine specific paths to zero-emissions.The risks for OEMs, in terms of long-term security-of-supply, contribute to a resistance to adopting new low carbon technologies into vehicle launch plans, with significant impacts on the UK's decarbonisation trajectory. Currently, UK supply chains for systems and ancillaries in these segments focus very much on diesel heavy-duty applications.**Opportunity**Whilst heavy-duty powertrain roadmaps ultimately culminate in zero-emission hydrogen fuel cell and battery electric vehicles, long-term OEM strategies will remain critically-dependent on next-generation internal combustion engines (ICE) to meet OEM requirements, whilst reducing average fleet emissions in line with European CO2 legislation and meeting Euro VII levels of pollutant emissions. See appendix 3Using hydrogen as a combustion fuel, so called H2-ICE, provides capability to meet heavy-duty/medium-duty requirements whilst delivering zero tank-to-tailpipe CO2 emissions.However, traditional approaches to conversion of this fuel have meant significant engine redesign and associated need for manufacturing and assembly investment in the supply chain, providing inertia against conversion to hydrogen.**Cavendish** **vision**In response, the PHINIA group -- Fuel Systems (PHINIA Delphi UK Ltd.) & Hartridge - and their partners in the supply chain -- BorgWarner, Mahle and Cambustion -- are pursuing a novel H2-ICE concept based on optimisation of existing heavy-duty diesel platforms to accommodate hydrogen as a fuel source, underpinned by novel fuel injection (PFI and HPDI options) and supporting turbocharger technology.The consortium's approach therefore targets conversion (rather than replacement) of current heavy-duty engine platform designs -- incorporating novel injection technology options into standard perpendicular cylinder engine designs -- hence negating the need for significant supply chain manufacturing/assembly infrastructure investment (as would be required with a full engine redesign).Conditional on achieving acceptable power density and thermal efficiency, developments can accelerate the adoption of H2-ICE and the displacement of diesel ICEs whilst safeguarding UK partners' positions in mature ICE-based supply chains.

**行业挑战**由于对动力总成成本性能、操作可用性、设计寿命和可靠性的要求，重型车辆的脱碳面临挑战，而任何现有的低碳动力总成方法（例如燃料电池）尚未完全满足这些要求、电池电动或混合动力架构。重型应用对这些技术的特定操作关键和拥有成本特征更加敏感，这给试图确定零排放具体路径的英国原始设备制造商带来了不确定性。风险就长期供应安全而言，原始设备制造商阻碍了在车辆推出计划中采用新的低碳技术，这对英国的脱碳轨迹产生了重大影响。目前，英国这些领域的系统和辅助设备供应链非常关注柴油重型应用。 **机遇**虽然重型动力总成路线图最终以零排放氢燃料电池和电池电动汽车为目标，但长期来看OEM 战略将继续严重依赖下一代内燃机 (ICE) 来满足 OEM 要求，同时根据欧洲二氧化碳立法减少平均车队排放量并满足欧 VII 污染物排放水平。请参阅附录 3 使用氢气作为燃烧燃料，即所谓的 H2-ICE，能够满足重型/中型要求，同时实现油箱到尾管二氧化碳零排放。然而，转换这种燃料的传统方法意味着显着的成本降低。发动机重新设计以及供应链中制造和装配投资的相关需求，提供了反对氢转换的惯性。**卡文迪什** **愿景**作为回应，PHINIA 集团——燃油系统（PHINIA Delphi UK Ltd.）和Hartridge 及其供应链中的合作伙伴 - 博格华纳、马勒和 Cambustion - 正在寻求一种新颖的 H2-ICE 概念，该概念基于对现有重型柴油平台的优化，以适应氢作为燃料来源，并以新颖的燃油喷射为基础。 PFI 和 HPDI 选项）以及支持涡轮增压器技术。因此，该联盟的方法旨在转换（而不是替换）当前的重型发动机平台设计，将新颖的喷射技术选项纳入标准垂直气缸发动机设计中，从而消除了这一需求用于重大供应链制造/装配基础设施投资（如全面重新设计发动机所需）。以实现可接受的功率密度和热效率为条件，开发可以加速 H2-ICE 的采用和柴油 ICE 的替代，同时保护英国合作伙伴” 在基于 ICE 的成熟供应链中的地位。
