Web2. 0.5% of all licensed vehicles in the UK in 2024 were ultra-low emissions vehicles. Road transport is an important source of both greenhouse gases and air pollutants, being responsible for significant contributions to emissions of carbon dioxide, nitrogen oxides, particulate matter (PM)10 and PM2.5. WebThese methods involved spark timing, carburetion, and exhaust recirculation. On one test car, a control system was developed which reduced nitrogen oxides 74% while maintaining hydrocarbon and carbon monoxide control at current (1968) federal levels. However, a 13% loss in fuel economy was incurred, and driveability problems were observed.
