WASHINGTON (CN) - The Environmental Protection Agency plans to make it cost effective for clean alternative fuel conversion systems manufacturers to continue to develop their systems, by simplifying the process by which they may demonstrate compliance with vehicle and engine emissions requirements.
Currently, the EPA requires all motor vehicles, including those with aftermarket conversion systems, to obtain certification by showing that the systems cannot be tampered with, and that they will meet emissions standards no matter how old the engine is. This makes it difficult for older engines to meet the standard.
The new program would facilitate age-appropriate testing and compliance procedures by placing alternative fuel conversions into one of three categories: conversions of vehicles or engines that are "new and relatively-new"; conversions of vehicles or engines that are no longer new but that still fall within the EPA's definition of full useful life; "intermediate age vehicles" and conversions of vehicles or engines that are outside of the EPA's definition of useful life.
The proposed distinctions between the demonstration required for new, intermediate age, and outside useful life vehicles and engines address the issues posed by the absence of applicable emission standards for converted vehicles and engines that have exceeded full useful life. As the age of the engine increases, the benchmark standard for emissions lowers, but the conversion system must either decrease the engines emissions or, at least keep them constant.
