Emissions
Since February
2001, Massachusetts has tested diesel vehicles for excess
pollution. The goal of the new inspection will be to
identify diesel vehicles with excess smoke emissions and promote
their repair. The SAE J1667 snap acceleration smoke test
will be implemented for heavy duty and light duty diesel vehicles.
Massachusetts has examined these cut points for you're vehicle to
pass:
Heavy Duty
Diesel Trucks (over 10,000 lbs.)
1991 and newer
must have less than 40% opacity to pass.
1990 and older down to
1984 must have less than 55% opacity
to pass.
Medium Duty
Diesel Trucks (8500 to 10,000 lbs.)
1984 and newer
must have less than 40% opacity to pass.
Using the Bosch RTT100A
Opacimeter (used by the state DEP), Boston Fuel Injection, Inc.
repairs diesel emission failures and re-inspects heavy and light
duty vehicles. Common smoke failure problems include
dirty fuel, incorrect engine timing, clogged filters, and
maintenance problems with your fuel injection system.
