Answer explanation

The correct definition of "abrasion" is "rubbing away or wearing of a part," which describes the process of material being worn down through friction. The other options do not relate to this definition.

Front

What does "ABS" stand for?

Back

Anti-lock brake system

Answer explanation

"ABS" stands for "Anti-lock brake system," which prevents wheel lock-up during braking, enhancing vehicle control and safety. The other options do not accurately represent the widely recognized meaning of "ABS."

Front

What is the function of an "actuator"?

Back

To deliver mechanical action in response to a signal.

Answer explanation

An actuator is a device that converts a signal into mechanical action, making it essential for controlling systems and machinery. Thus, the correct function is to deliver mechanical action in response to a signal.

Front

What is "amplify" used for in electronics?

Back

To enlarge or strengthen original characteristics.

Answer explanation

In electronics, 'amplify' refers to the process of enlarging or strengthening the original characteristics of a signal, making it more powerful for further processing or transmission.

Front

What is "antifreeze" used for?

Back

To lower the freezing point of water.

Answer explanation

Antifreeze is primarily used to lower the freezing point of water, preventing it from freezing in cold temperatures, which is essential for maintaining the proper functioning of engines and cooling systems.

Front

What is the term for the sudden combustion of gases in the intake or exhaust manifold, resulting in a loud explosion?

Back

Backfire

Answer explanation

The term for the sudden combustion of gases in the intake or exhaust manifold, resulting in a loud explosion, is 'backfire'. This phenomenon occurs when fuel ignites outside the combustion chamber.

Front

Component used to reduce voltage by approximately 4-5 volts in the ignition system.

Back

Ballast resistor

Answer explanation

The ballast resistor is used in ignition systems to reduce voltage by about 4-5 volts, ensuring proper operation of the ignition coil and preventing overheating. This makes it the correct choice among the options provided.

Front

What is the purpose of a balance shaft in some engines?

Back

To reduce vibration

Answer explanation

The purpose of a balance shaft in some engines is to reduce vibration. It counteracts the forces generated by the engine's moving parts, leading to a smoother operation and improved comfort for the driver.

Front

What is the term for the unburned fuel and products of combustion that leak past the piston rings?

Back

Blowby

Answer explanation

The term for unburned fuel and combustion products that escape past the piston rings is 'blowby'. This occurs when the pressure in the combustion chamber exceeds the sealing capability of the piston rings.

Front

What is the function of a bearing race?

Back

To provide a surface for roller or ball bearings

Answer explanation

The function of a bearing race is to provide a smooth surface for roller or ball bearings to rotate against, reducing friction and wear in mechanical systems.
