Researchers capture first images of CO2 emissions from commercial aircraft engine using chemical species tomography

Green Car Congress

Researchers have used a novel near-infrared light imaging technique to capture the first cross-sectional images of carbon dioxide in the exhaust plume of a commercial jet engine. To image such a large area, the researchers used a 7m-diameter optical mounting frame (red) located just 3 m from the exit nozzle of the engine.

SJTU team investigating ammonia HCCI combustion in free piston engine

Green Car Congress

Researchers at Shanghai Jiao Tong University are investigating ammonia-fueled HCCI combustion in a free piston engine. Ammonia is a promising carbon–neutral fuel, able to power heavy-duty vehicles, non-road machineries and ocean ships with zero CO 2 emission. 2023.127634

A Bamboo Carbon Filter for Diesels Could Reduce Emissions

Cars That Think

After all, diesel cars cost less to maintain, burn less fuel, and have a longer engine life. Although the pollutant emissions of a diesel engine are less than those of a gasoline one, it still emits carcinogens, nitrous oxides, and soot. Activated carbon granules in an absorption chamber and metallic mesh form the filters, Afrin says.

Study finds engines emit exhaust nanoparticles even when not fueled during engine braking

Green Car Congress

Exhaust particle size distributions measured by ELPI (color map) and particle concentration measured by CPC (white line) during individual engine braking conditions (speed change from 32 km/h to 0 km/h). The starting point of engine braking is marked by a vertical green line, and the end point is marked by a vertical red line.
