State the different ways of monitoring fuel oil quality and how to maintain an acceptable value during operation.
Which of the following statements about carbondioxide is not true?a. CO2 levels are highest when the air-fuel ratiois slightly leaner than stoichiometric.b. The production of CO2 is directly related tothe amount of fuel consumed; therefore,more fuel-efficient engines produce less CO2c. To reduce CO2 levels in the exhaust, engineers are working hard to decrease fuel consumption to keep CO2low.d. The concern for CO2 emissions is one of theprimary reasons for the delayed use of alternative fuels for automobiles.
Excessive oxygen in the exhaust indicates an improper air/fuel mixture.

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.

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.arrow_forward
