When the water pump is removed, severe corrosion is found on the water pump impeller, and inside the engine. Technician A states that the radiator cap may be overpressurizing the system. Technician B states that the vehicle may have been run with 100% water in the cooling system for some time. Who is correct? Select one: a. Technician A only b. Technician B only c. Both Technicians A and B d. Neither Technician A nor Barrow_forwardWhile discussing the MIL on OBD II systems: Technician A says that the MIL will flash if the PCM detects a fault that would damage the catalytic converter.

Technician B says that the computer will compensate for the improper air-fuel ratio caused by fuel boiling in the fuel rail. Who is correct?arrow_forwardTechnician A says that during oxidation, as NOx gases pass over the catalyst, the N atoms are pulled from the NOx molecules and are absorbed by the catalyst. The released oxygen atoms then flow through the converter to the second bed. The result of NOx oxidation is pure nitrogen plus oxygen or carbon dioxide. Technician B says that during the reduction phase inside the converter, hydrocarbon and carbon monoxide molecules experience a second combustion. The result of this combustion or oxidation process is water vapor and carbon dioxide. Who is correct? a. Technician A only b. Technician B only c. Both A and B d. Neither A nor Barrow_forward
- 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.arrow_forwardWater Calcium oxide A student working in lab is reacting calcium oxide with water by dropping lumps of calcium oxide into the distilled water. CaO (s) + H20 (e) → Ca(OH)2 (aq) Which actions or changes can the student make to increase the number of effective collisions between CaO and H2O? [Check all that are correct.] Use a larger beaker. 2 Add heat. Decrease the amount of water. O Grind the lumps of calcium oxide. up Use a catalyst.arrow_forwardIncomplete combustion is permitted because a significant amount of heat is still generated. true of falsearrow_forward
- Which of the following statements about fuel cells is NOT true?a. A single fuel cell produces very low voltage, normally less than one volt.b. A fuel cell produces electricity through an electro-chemical reaction that combines hydrogen and oxygen to form water.c. A fuel cell is composed of two electrodes coated with a catalyst and separated from each other by an electrolyte and from the case by separators.d. In a fuel cell, catalysts are used to ignite the hydrogen; this causes a release of electrons or electrical energy.arrow_forwardMake a research on the latest development in the field of emission control technology.arrow_forwardExplain the steps involved in disconnecting a fuel line on a vehicle with: Multiport fuel injection (50 - 60 words) Gasoline Direct Iniection (30 - 40 words)arrow_forward
