Reducing the greenhouse gas emission from modern energy systems is critical to manage climate change. For systems such as heavy duty or marine engines, where electrification is not yet possible, natural gas can be an attractive alternative. For example, natural gas (NG) and NG from renewable sources (RNG) can result in lower carbon dioxide, nitrogen oxide, sulfur and particulate emissions than conventional fuels. Several fueling technologies exist for natural gas and RNG; however, the engine performance and exhaust emissions are closely related to the engine operating strategy, and excessive methane emissions results in an increase greenhouse gas emissions. In this work we aim to reduce the greenhouse gas emissions from natural gas and RNG engines using a combination of optical and multi-cylinder engine experiments, as well as field measurements of greenhouse gas emission from in-use engines. This will provide technologies for low greenhouse gas emission transportation systems. Furthermore, the emission measurements will provide a basis for effective emission and air quality policy decisions for emerging engine fueling technologies.

减少现代能源系统的温室气体排放对于管理气候变化至关重要。对于重型或船用发动机等系统，电气化尚不可能，天然气可能是一种有吸引力的替代品。例如，天然气（NG）和来自可再生资源的天然气（RNG）可以导致比传统燃料更低的二氧化碳、氮氧化物、硫和颗粒物排放。天然气和可再生天然气有多种燃料技术，但发动机性能和排放与发动机运行策略密切相关，过量的甲烷排放会导致温室气体排放增加。在这项工作中，我们的目标是减少温室气体排放的天然气和RNG发动机使用的光学和多缸发动机实验的组合，以及在使用的发动机的温室气体排放的现场测量。这将为低温室气体排放的运输系统提供技术。此外，排放测量将为新兴发动机加油技术的有效排放和空气质量政策决策提供基础。
