A Bamboo Carbon Filter for Diesels Could Reduce Emissions

Cars That Think

Diesel cars are a popular choice for those looking to buy a used vehicle in Asia, Europe, and elsewhere. After all, diesel cars cost less to maintain, burn less fuel, and have a longer engine life. To reduce emissions, diesel vehicles use filters that catch exhaust particles and other contaminants.
