What components are primarily included in a vehicle's powertrain?
Correct!
Wrong!
The powertrain includes the engine, transmission, driveshaft, differential, and axle, which work together to move the vehicle.
What is the main function of the transmission in an automotive powertrain?
Correct!
Wrong!
The transmission controls the application of power from the engine to the drive wheels by shifting gears.
What advantage do turbocharged engines have over naturally aspirated engines?
Correct!
Wrong!
Turbocharged engines force more air into the combustion chamber, increasing power output without increasing engine size.
Which part of the engine converts linear piston motion into rotary motion?
Correct!
Wrong!
The crankshaft transforms the up-and-down motion of the pistons into rotational motion that drives the wheels.
How does a hybrid powertrain improve fuel efficiency?
Correct!
Wrong!
Hybrid systems combine internal combustion engines with electric motors, reducing fuel use during low-speed and stop-start driving.
What is the role of the timing belt in an engine?
Correct!
Wrong!
The timing belt synchronizes the rotation of the crankshaft and camshaft, ensuring valves open and close at the right times.
