Accepted Answer

Ford's hybrid system, used in the Escape and Fusion, was developed with technology licensed from Toyota, making them similar in operation.

Question 12

Ford Motor Company uses planetary gear sets in their hybrid vehicles to create a ________ when it is requested by the driver.
A) High ratio
B) Low ratio
C) Neutral
D) None of the above

Accepted Answer

The answer of Ford Motor Company uses planetary gear sets...

Question 13

Ford advertises their Continually Variable Transmissions (CVTs) as two-speed CVTs.

Accepted Answer

CVTs are typically single-speed transmissions, not two-speed.

Question 14

In Mode 1 of a two-mode hybrid, the electric motor/generators, in combination with the planetary gear sets, allow the transmission to operate as a type of ________, keeping the engine operating in its most efficient rpm range.
A) Continuously Variable Transmision (CVT)
B) Integrated Motor Assist (IMA)
C) Belt Alternator Starter (BAS)
D) None of the above

Accepted Answer

In Mode 1 of a two-mode hybrid, the system operates similarly to a Continuously Variable Transmission (CVT), allowing the engine to run efficiently by adjusting the gear ratios seamlessly.

Question 15

In a two-mode hybrid, the Powertrain Control Module can phase in and out each of the ________ to create four distinct gear ratios.
A) Compressors
B) Generators
C) Motors
D) Planetary gear sets

Accepted Answer

Planetary gear sets are used to create different gear ratios in a two-mode hybrid powertrain.

Question 16

During Mode 1 of a two-mode hybrid vehicle, only the gasoline engine is running to propel the vehicle.

Accepted Answer

Mode 1 of a two-mode hybrid vehicle typically involves using both the gasoline engine and the electric motor to propel the vehicle, not just the gasoline engine alone.

Question 17

Mode 2 of a two-mode hybrid is used at low speeds and light engine load.

Accepted Answer

The answer of Mode 2 of a two-mode hybrid is...

Question 18

Which of the following hybrid systems cannot drive using the electric motor only?
A) Integrated motor assist (IMA)
