After temporal displacement, the louvers would rapidly expel a cloud of gas, cooling internal components. Later, after the DeLorean's hover conversion in 2015, they were used to propel the DeLorean whilst in flight. During operating, they glowed a bright white color. After the initial acceleration, the louvers would cease glowing.
It is possible that they provided more precise control of the vehicle while in flight, and likely gave an extra boost of acceleration.
A similar series of louvers were used on the Jules Verne Train for the same purposes.
Another similar series of louvers appear in the video games series, utilized in young Doc's rocket-powered drill, and later attached to Edna Strickland's bicycle to create a rocket powered bicycle. It is possible that this design is what inspired the louvers on the DeLorean.
