Which of the following statements about vehicles that are subject to Diesel Opacity Emissions (Smoke Meter) Inspection is NOT true?
Only diesel powered vehicles with a Gross Vehicle Weight Rating (GVWR) over 8,500 pounds, per New York State Department of Environmental Conservation (DEC) regulations.
“DEMA” will appear on a vehicle's New York State registration to indicate that the vehicle is subject to an opacity smokemeter test (in addition to the safety inspection).
The “DEMA” (Diesel Emissions Metropolitan Area) Counties include Suffolk, Nassau, Queens, Kings, Richmond, New York, Bronx, Westchester & Albany.
Only diesel powere
Which of the following statements regarding the “Pre-Emission Inspection Check” Of a diesel powered vehicle that is subject to Opacity (Smoke Meter) testing is not true?
The governor (if equipped), the exhaust system, and the emissions control devices must all be checked.
The exhaust system must be checked for any missing sections which would prevent collection of a valid exhaust sample.
Vehicles not meeting requirements cannot be inspected. This is not considered an inspection or rejection and no fee is to be charged.
The governor, if originally equipped, must be checked for presence, connection, and operation.
When performing an engine oil level
check, if additional oil is needed, estimate
the amount by checking the emissions
standards guide to the dipstick markings.

- Which of the following statements about fuel trim is not true? a. A positive fuel trim value means that the PCM detects a lean mixture and is decreasing the pulse width to add more fuel to the mixture. b. Short-term fuel trim represents changes made immediately in response to HO2S signals. c. Long-term fuel trim represents changes made to set a new base pulse width. d. Long-term fuel trim responds to the trends of the short-term fuel trim.arrow_forwardWhich of the following statements about a fuel volume test is not true? a. This test measures the flow rate of the pump and can help isolate fuel system restrictions or weak pumps. b. The test is conducted by collecting the fuel dispensed by the certain during a period of time, normally 5 seconds. c. The flow of fuel into the container should be smooth and continuous with no signs of air bubbles. d.
