Question 1: The brake caliper is an assembly that houses the

• drum brakes
• brake shoes
• brake boosters
• brake pads and pistons

Answer:

The correct answer is (D) brake pads and pistons. Disc brakes slow the rotation of the wheels using friction, which is created by pushing the brake pads against the brake discs with a set of calipers.Question 2: An internal combustion engine in which the cylinders are aligned in two banks, which are at an angle to each other, is known as a

• inline engine
• rotary engine
• V-engine

D.boxer engine

Answer:

The correct answer is (C) V-engine. The angle of the two cylinder banks makes a "V" shape.

Question 3: The coolant in a car flows through the:

• differential.
• brakes.
• distributor.
• engine block.

Answer:

• engine block.

Question 4: In a four-stroke engine, which of the following is NOT one of the four strokes?

• Intake
• Compression
• Out-take
• Exhaust

Answer:

The correct answer is (C) Out-take. Each stroke is the movement of the piston from one end of the cylinder to the other. The four strokes are called Intake, Compression, Power, and Exhaust.Question 5: Which of the following is NOT part of an internal combustion engine?

• piston ring

B.connecting rod

• clutch

D.cylinder head

Answer:

The correct answer is (C) clutch. The clutch is part of the drive train system.

Question 6: The part of the tire that grips the rim of the wheel is the

• bead
• sidewall
• shoulder

• ply

Answer:

The correct answer is (A) bead. The bead is the inner edge of a tire. It is normally made with high-strength rubber and is reinforced with steel wire.Question 7: In the diagram above, what is the location of the fuel pressure regulator?See Picture

• A
• B
• C
• D

Answer:

The correct answer is (C). As pictured above, the fuel pressure regulator regulates pressure in the fuel rail according to intake manifold vacuum.Question 8: Which part of the fuel system sprays a fuel and air mixture into the engine's combustion chamber?

• fuel pump
• fuel injector

C.fuel filter

• fuel pressure regulator

Answer:

The correct answer is (B) fuel injector. Fuel injectors atomize the fuel by pumping it through a small nozzle under high pressure. Atomizing the fuel is the process of breaking it into a fine misted spray.Question 9: What part of a car's exhaust system is responsible for turning the toxic components of engine exhaust into less toxic compounds?

• cylinder head
• exhaust manifold
• muffler

• catalytic converter

Answer:

The correct answer is (D) catalytic converter. After being collected in the exhaust manifold, exhaust gases are then sent to the catalytic converter where toxic pollutants are converted into less toxic compounds by catalyzing a redox reaction.

Question 10: Which system is required to start an automobile?

• Electrical
• Electrical
• Electrical
• Drive train

Answer:

The correct answer is (A) Electrical. A car's electrical system controls lighting, starting, charging, and accessories.Question 11: If one complete revolution of the steering wheel causes the wheels to turn 20 degrees, what is the steering ratio?

A. 12:1

B. 15:1

C. 18:1

D. 20:1

Answer:

The correct answer is (C) 18:1. A complete revolution of the steering wheel is 360 degrees. Thus, the steering ratio is 360:20 which reduces to 18:1 (360/20=18).Question 12: Which of the following is the location of the differential on a drive axle?See Picture

• A
• B
• C
