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.

- What is the testing procedure for diesel systems as outlined by the national environment protection (diesel vehicle emissions) measure?arrow_forwardThe primary difference between these non-road (off road) types of diesel fuel is one contains a red dye and one does not. Otherwise the two diesel fuels are relatively identical. In some states there may be a higher level of sulfur in the off road diesel. From a regulatory perspective, the off road diesel tank is not regulated and is not required to have the leak detection, spill prevention or overfill prevention that a regulated tank is.
