The Diesel Opacity (Smoke Meter) Emissions Inspection procedure requires that the Certified Inspector use an approved diesel opacity (smoke meter) tester to check emissions at the tailpipe and that the following must also be hooked up during the test
During the Diesel Opacity (Smoke Meter) Emissions Inspection procedure, in addition to using an approved diesel opacity (smoke meter) tester to check emissions at the tailpipe, the following equipment must also be hooked up and used during the test:
-
Exhaust gas temperature (EGT) sensor: This sensor is used to measure the temperature of the exhaust gas as it exits the tailpipe. It is important to monitor this temperature to ensure that the exhaust gas is at the correct temperature range for accurate testing.
-
Ambient temperature sensor: This sensor measures the temperature of the surrounding air. It is important to know the ambient temperature because it can affect the performance of the diesel engine and the accuracy of the smoke meter test.
