What is the Function of an Engine Diaper?

An engine diaper, also known as an engine containment system or engine containment device, is a safety component designed to prevent debris and fluids from escaping in the event of engine failure or a serious accident. It is commonly used in high-performance racing vehicles, such as dragsters, funny cars, and certain types of race cars.

In high-speed racing, particularly with powerful engines, there is a risk of catastrophic engine failure, which can lead to parts of the engine or other components being expelled at high velocity. The engine diaper is a specialized barrier made from strong and heat-resistant materials that surround the bottom of the engine, extending to cover the sides and front of the engine. In case of an engine failure, the diaper is intended to contain any flying debris, broken parts, or fluids within the protective enclosure, reducing the risk of harm to the driver, other vehicles, or spectators.

The engine diaper is just one of several safety measures used in motorsports to minimize the potential hazards associated with high-speed racing.
