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

When the four-stroke auto-rickshaws were separated into “new” and “old” groups and their emissions compared by fuel type, no significant difference was observed for any exhaust constituents except for NO x from the gasoline-fueled vehicles. The mean fuel-based PM 2.5 emission factor (mean (95% confidence interval)) for CNG-2S (14.2
