Devices that bypass diesel vehicle emission controls allow drivers to emit clouds of black exhaust
The US Department of Justice (DOJ) is suing eBay, alleging that it has sold more than 343,000 ‘rolling coal’ devices and other equipment that deliberately pollutes the environment and violates the Clean Air Act. The retailer, reportedly facing a fine more than $5000 (£4000) for each alleged transaction, denies the charges and claims that it banned the sales of these devices.
Rolling coal devices modify a diesel engine to emit sooty, black clouds from its exhaust. These devices defeat vehicle emission controls significantly increasing the emission of pollutants including carbon monoxide, nitrogen oxides and particulate matter.
