Impact of Natural Gas Composition on the Performance and Emission of Heavy/Medium-Duty Natural Gas Vehicles - Phase 2
Natural gas fuel composition can have an impact on emissions for older technology heavy-duty vehicles
Project completed and final report published on the CEC website.
This project evaluated the impact of various NG compositions on the performance and emissions of NG powered heavy- and medium-duty vehicles, including identifying and obtaining vehicles/engines to test, selecting natural gas blends to test, obtaining gases, testing and data analyses. Testing addressed issues such as the impact of the different LNG blends on fuel economy, operability and emissions of air pollutants. The results showed that fuel composition, engine operating conditions, and driving cycle had effects on the formation of exhaust emissions from all the older heavy-duty vehicles.
