A Bamboo Carbon Filter for Diesels Could Reduce Emissions

Cars That Think

To reduce emissions, diesel vehicles use filters that catch exhaust particles and other contaminants. Looking to make replacement filters more environmentally friendly and affordable, a team of engineering students from the Bangladesh University of Engineering and Technology , in Dhaka, designed a carbon-based version with bamboo.

Study of emissions from CNG- and gasoline-fueled autorickshaws suggests measurements and data, not assumptions, should drive policy

Green Car Congress

Chassis dynamometer emission testing conducted on 30 in-use Indian auto-rickshaws—two-stroke and four-stroke CNG-fueled (CNG-2S and CNG-4S) and four-stroke gasoline-fueled (PET-4S)—found that global warming commitment (GWC) associated with emissions from CNG-2S was more than twice that from CNG-4S or PET-4S, due mostly to CH 4 emissions.
