Two technicians are discussing CVT transmissions. Technician A says that when a CVT-equipped car is accelerating, the engine RPM remains constant as the mph increases. Technician B says that some CVT vehicles do not have torque converters. They use a multiple disc starting clutch for idling and starting from a dead stop.
A)A only
B)B only
C)both A and B
D)neither A nor B

Question

Quizplus · Accepted Answer

Technician A is correct because in a CVT (Continuously Variable Transmission), the transmission can adjust to keep the engine in its optimal power range, which can result in the engine RPM staying relatively constant during acceleration. Technician B is also correct because some CVT designs, especially in hybrid vehicles or more advanced systems, use a multi-disc clutch instead of a traditional torque converter to manage power delivery from a stop and during low-speed operation.
