Comparison of brake thermal efficiency and specific fuel consumption at rated power (ICOMIA Mode 5), hydrogen vs. gasoline engines. It, or a scaled-up version, could also provide a solution for the Asian motor vehicle fleet, in which two-stroke engine vehicles constitute a major share—and contribute significantly to air pollution.

In part it is difficult to identify significant air quality improvements from a specific program—especially one targeted at a small area within a large city—against the backdrop of broader regional pollutant and weather changes. Within the CCZ, the investigators projected a net decline of 1.7 µg/m 3. in PM 10.

They found that the level of emissions of regulated and unregulated pollutants in diesel exhaust depends on fuel, load, engine calibration, and exhaust aftertreatment technology. Unregulated pollutants also include ozone precursors and bioaccumulative and toxic compounds. L) and medium-duty (6.4 —Chin et al.
