While discussing returnless fuel systems: Technician A says that in a returnless fuel system the pressure regulator is mounted on the fuel rail. Technician B says that in this type of fuel system the pump and pressure regulator are combined in one unit. Who is correct?
A.Technician A
B.Technician B
C.Both A and B
D.Neither A nor B
A technician is inspecting a vehicle and finds
the upper radiator hose is collapsed, and the
cooling system pulled into a vacuum when
cold. Technician A states that a leak in the
surge tank could be the cause. Technician B
states that the radiator cap is most likely
defective. Who is correct?
Select one:
a. Technician A only
b. Technician B only
c. Both Technicians A and B
d. Neither Technician A nor B
Technician A says that air-fuel ratios can be regulated by controlling the “on time” of the injectors. Technician B says that the air-fuel ratio can be regulated by controlling the pressure applied to the individual injectors. Who is correct?

- 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_forwardExcessive oxygen in the exhaust indicates an improper air/fuel mixture. True Falsearrow_forwardTechnician A says that black exhaust smoke is an indication of a too-rich air-fuel mixture. Technician B says that white smoke (steam) is an indication of coolant being burned in the engine.arrow_forward

Faulty fuel pump Faulty fuel pressure regulator Restricted fuel delivery system All of the abovearrow_forwardWhile discussing quick-disconnect fuel line fittings: Technician A says that on some hand-releasable, quick-disconnect fittings, the fitting may be removed by pulling on the fuel line. Technician B says that some hand-releasable, quick-disconnect fittings may be disconnected by twisting the large connector collar in both directions and pulling on the connector. Who is correct?arrow_forwardA chamber installed in the exhaust flow that contains material that aids emission reduction via chemical reaction. a. muffler b. exhaust filter c. catalytic converter d. emission filterarrow_forward

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_forwardA vehicle is having its water pump replaced. 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.
