Transmission
Transfer case
Differential
Drive shaft
#5
What is the purpose of a locking differential in a 4WD vehicle?
To improve fuel efficiency
To allow for different wheel speeds when turning
To prevent loss of traction by locking both wheels on an axle together
To disengage the transmission
#6
Which of the following is a characteristic of a part-time 4WD system?
Always engaged
Selectable by the driver
Uses center differential
Suitable for all road conditions
#7
In a part-time 4WD system, when is four-wheel drive typically engaged?
Automatically based on road conditions
Only when selected by the driver
Always engaged
Only during high-speed driving
#8
Which type of differential is commonly used in modern 4WD systems to allow for different wheel speeds during turns?
Limited-slip differential (LSD)
Open differential
Locking differential
Torsen differential
#9
What is the purpose of a rear differential lock in a 4WD vehicle?
To increase fuel efficiency
To reduce traction
To improve off-road performance
To engage cruise control
#10
Which type of 4WD system allows for automatic distribution of power between the front and rear wheels as needed?
Part-time 4WD
Full-time 4WD
On-demand 4WD
Permanent 4WD
#11
What is the primary difference between a 4WD system and an AWD (All-Wheel Drive) system?
There is no difference; the terms are interchangeable
AWD systems are always engaged, while 4WD systems can typically be engaged or disengaged by the driver
AWD systems are only found in luxury vehicles, while 4WD systems are found in trucks and SUVs
4WD systems are more fuel-efficient than AWD systems
#12
What is the purpose of the 'neutral' setting in a transfer case?
To engage four-wheel drive
To disengage the transmission
To disconnect power from all wheels
To allow the vehicle to roll freely without engine power
#13
What is the purpose of a transfer case in a 4WD vehicle?
To control steering
To engage and disengage four-wheel drive
To regulate engine temperature
To adjust suspension height
#14
In a 4WD vehicle, what does 'low range' mode typically provide?
Higher top speed
Improved fuel efficiency
Increased engine power and torque at lower speeds
Better handling on paved roads
#15
What is the function of a center differential in a full-time 4WD system?
To allow for different wheel speeds when turning
To lock the front and rear axles together
To engage low range mode
To transfer power between the front and rear axles
#16
What is meant by 'crawl ratio' in relation to 4WD vehicles?
The maximum speed the vehicle can crawl in low range mode
The ratio between engine speed and vehicle speed
The torque multiplication provided by the transmission in low range mode
The ability of the vehicle to crawl over obstacles without stalling
#17
What feature of a locking center differential allows for better off-road performance?
Allows for equal distribution of power to all wheels
Prevents wheel slippage by locking both front and rear axles together
Enables the vehicle to maintain traction on uneven surfaces
Reduces stress on the drivetrain during sharp turns
#18
Which type of 4WD system is typically found in vehicles designed for extreme off-road conditions?
Full-time 4WD
On-demand 4WD
Permanent 4WD
Selectable 4WD
