Exam 4: Automotive Systems

The compressor in an air-conditioning system can be turned on and off by means of an electromagnetic ____________________.

The biggest part of the engine is the cylinder (engine) ____________________.

The ____________________ manifold delivers a mixture of air and fuel to the intake ports.

A RWD vehicle that is equipped with independent rear suspension has a rear differential and drive axle shafts similar to a FWD vehicle.

Which type of engine is classified as internal combustion?

The sump is also called the ____________________.

In body-over-frame construction, the body is supported to the frame by large rubber mounts.

Which component is located in the vehicle's exhaust system?

Which of the following components is not a part of an air-conditioning system?

Identify the components included in a vehicle's charging system.

Identify the major components of an air-conditioning system.

Air-cooled engines are not generally used on modern cars because it is very difficult to maintain constant temperatures at the cylinders. If the cylinder temperature is not accurately controlled, the engine will not run efficiently.

Which one of the following is NOT a function of the exhaust system?

What component in the cooling system raises the boiling point of the coolant?

In body-over-frame construction, the frame is the vehicle's foundation.

Technician A says hybrid cars must be plugged in at night to recharge the batteries. Technician B says a hybrid cannot be a high performance vehicle because the electric generator constantly uses energy to recharge the batteries, robbing power from the gasoline engine. Who is correct?

____________________ is the burning of an air and fuel mixture.

Hybrid vehicles are being discussed. Technician A says a hybrid can run on electric power or on the internal combustion motor, but never on both. Technician B says the internal combustion engines used in hybrids are specially designed to be assisted by electric power and as a result are more fuel efficient and cleaner than conventional engines. Who is correct?

Technician A says a torsion bar is a type of shock absorber. Technician B says shock absorbers slow the upward and downward movement of the vehicle after a bump. Who is correct?

Technician A says power brake systems use a vacuum booster to increase the force applied to the master cylinder. Technician B says power brake systems use hydraulic pressure from the power steering pump to increase the force applied to the master cylinder. Who is correct?
