CALA Automotive Systems and Terminology 5

Question 1

What distinguishes a 'CVT' (Continuously Variable Transmission) from a traditional automatic transmission?

Accepted Answer

A CVT provides an infinite range of gear ratios using a belt and pulley system rather than fixed gear steps

Answer

A CVT uses a variable-diameter pulley and belt system to provide seamless, stepless gear ratio changes across a continuous range, unlike fixed-ratio automatic transmissions.

Question 2

When evaluating a vehicle with a damaged 'subframe,' what concern does this raise for a loss adjuster?

Accepted Answer

The subframe is a major structural component that mounts the engine, transmission, and suspension, so damage may indicate significant hidden structural issues

Answer

The subframe (or cradle) is a critical structural member that supports the powertrain and suspension; damage to it can indicate severe structural compromise and affect repairability.

Question 3

What is 'brake fade,' and when is it most likely to occur?

Accepted Answer

A reduction in braking effectiveness due to heat buildup in the braking system, common after repeated hard stops

Answer

Brake fade occurs when excessive heat reduces friction between pads and rotors or causes brake fluid to vaporize, significantly reducing stopping power.

Question 4

A damaged vehicle has a destroyed 'front impact bar' (also called a bumper reinforcement bar). What is its primary safety function?

Accepted Answer

To distribute and absorb low-speed impact energy before it reaches the vehicle frame rails

Answer

The bumper reinforcement bar is a rigid beam behind the bumper cover designed to absorb and spread low-speed collision energy across its width before reaching structural frame rails.

Question 5

In automotive terminology, what is a 'direct injection' fuel system?

Accepted Answer

A system that injects fuel directly into the combustion chamber at high pressure

Answer

Direct injection (GDI/DISI) sprays fuel at very high pressure directly into the combustion chamber rather than the intake port, improving efficiency and power.
