Question

Solar radiation is increased inside the passenger compartment by increasing __________ of a car.

• A. Roof camber
• B. Wind screen angle
• C. Bonnet angle
• D. Diffuser angle

Hint:

When designing or modifying a car, consider the angle of the windscreen to manage heat gain from solar radiation, which can affect passenger comfort and air conditioning load.

Answer 1

The Correct Option is B

Increasing the angle of the windscreen can lead to more direct sunlight entering the passenger compartment, thus increasing the amount of solar radiation inside. This is due to the angle of incidence and the reflective properties of glass, which can allow more solar energy to penetrate the vehicle when the angle is adjusted to be more perpendicular to the sun's rays.
