2010 heavy duty diesel onboard diagnostics requirements updated

摘要

The environmental Protection Agency (EPA) has come out with regulations mandating emissions control systems of diesel engines used in highway vehicles. These regulations require that these systems be monitored similarly to passenger cars via onboard diagnostic (OBD) systems. This was the subject of another TMC technical section. These regulations, which apply to vehicles more than 14,000 pounds, begin in 2010 and will be phased in over a number of years due to the development effort required and to provide the trucking industry with a learning period.
