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.arrow_forward
