Natural gas (predominantly methane, CH4) is an abundant, cleaner-burning fuel than gasoline, particularly when combined with hydrogen (H2). Westport Innovations Inc. of Vancouver, BC is a world-leading company that provides technology to transform diesel engines to operate on natural gas, biogas, propane, and hydrogen, with a focus on medium and heavy duty vehicles such as transit buses, delivery vehicles, refuse collection trucks, and large highway trucks. A significant impediment to the widespread implementation of natural gas in combustion engines is that unburned CH4 expelled in the exhaust is a significant greenhouse gas with a potency more than ~25 times that of carbon dioxide. Traditional catalytic converters, optimized for reducing oxides of nitrogen (NOx), unburned hydrocarbons, and carbon monoxide, are not efficient at methane

天然气（主要是甲烷，CH4）是一种比汽油丰富、燃烧更清洁的燃料，特别是与氢气 (H2) 结合时。位于不列颠哥伦比亚省温哥华的 Westport Innovations Inc. 是一家世界领先的公司，提供将柴油发动机改造为使用天然气、沼气、丙烷和氢气运行的技术，重点关注中型和重型车辆，如公交巴士、送货车辆、垃圾收集车和大型公路卡车。天然气在内燃机中广泛应用的一个重大障碍是，废气中排出的未燃烧的 CH4 是一种重要的温室气体，其效力约为二氧化碳的 25 倍以上。传统的催化转化器针对减少氮氧化物 (NOx)、未燃烧的碳氢化合物和一氧化碳进行了优化，但在处理甲烷方面效率不高
