In Canada and across the world, commercial vehicles are central to economic activity but are responsible for significant greenhouse gas emissions. Substantially reducing the climate impacts of goods transport without increasing costs is a major challenge. Combining existing engine technology with clean-burning fuels and a high-efficiency hybrid-electric powertrain offers a promising near-term approach to address this pressing problem. In this project, experts from the University of Alberta and Simon Fraser University will collaborate with Vancouver-based Westport Fuel Systems Inc. to investigate the potential emissions and fuel consumption benefits of a hybrid-electric commercial vehicle fueled with a range of low-carbon gaseous fuels.The project will involve detailed modelling and optimization of the electric drive system, internal combustion engine, and on-board energy storage. The project will target a medium-heavy duty truck combined with a low-cost, high-efficiency natural gas engine as the main power source. The engine size and combustion system will be carefully optimized to match the required performance of the hybrid-electric powertrain. Simultaneously, the powertrain will be configured to make best use of the power provided from the engine while following the target drive profile. The additional benefits for both tailpipe and net greenhouse gas emissions from renewably generated gaseous fuels, such as bio-gas or hydrogen, will also be assessed. The results from this project will be the structural design of a commercially viable powertrain system that can provide dramatic reductions in greenhouse gas emissions for commercial transport.

在加拿大和世界各地，商用车是经济活动的核心，但负责大量的温室气体排放。在不增加成本的情况下，大大降低了货物运输的气候影响是一个主要挑战。将现有的发动机技术与清洁燃烧燃料和高效混合电动动力总成相结合，提供了一种有希望的近期方法来解决这一紧迫问题。在该项目中，艾伯塔大学和西蒙·弗雷泽大学（Simon Fraser University）的专家将与位于温哥华的Westport Fuel Systems Inc.合作，调查与一系列低碳气体燃料的混合电动商用车的潜在排放和燃料消耗益处。该项目将涉及电动驱动系统的详细建模和优化电动机系统，以及内部装备工具，并加入了装备工具，并加上型号。该项目将以中等重型的卡车为目标，再加上低成本，高效率的天然气发动机作为主要电源。发动机尺寸和燃烧系统将经过仔细优化，以匹配混合电动动力总成所需的性能。同时，将配置动力总成，以充分利用在目标驱动器配置文件的同时提供的发动机。还将评估来自重新产生的气体燃料（例如生物气或氢）的尾管和净温室气体的额外好处。该项目的结果将是商业上可行的动力总成系统的结构设计，该系统可以为商业运输提供大量减少温室气体排放。
