Final Rule for Control of Emissions of Air Pollution From New Motor Vehicles: In-Use Testing for Heavy-Duty Diesel Engines and Vehicles
On this page:
The U.S. Environmental Protection Agency (EPA) is establishing a manufacturer-run, in-use emissions testing program for heavy-duty diesel trucks. Under this program, manufacturers will measure gaseous and particulate exhaust emissions from diesel engines using portable onboard emission measurement systems. This cooperative effort represents a significant advance in helping to ensure that the benefits of more stringent emission standards are realized under real-world driving conditions.
