Question

deactivates cylinders when operating under cruise or coasting conditions to save fuel.
a. power - on - demand
b. power splitting
c. displacement - on - demand
d. regenerative braking

Explanation:

• Power - on - demand: This term is not typically associated with cylinder deactivation for fuel - saving in the context of engine operation.
• Power splitting: Usually refers to distributing power between different components (e.g., in hybrid vehicles between engine and electric motor) rather than cylinder deactivation.
• Displacement - on - demand: This technology deactivates cylinders when the vehicle is operating under light load (such as cruise or coasting) to reduce fuel consumption by effectively reducing the engine's displacement.
• Regenerative braking: Converts kinetic energy into electrical energy (in hybrid/electric vehicles) during braking, not related to cylinder deactivation.

Answer:

C. Displacement - on - demand
