Here's how it works:
* The water evaporates in the engine's hot intake, which cools the air and increases the air's density.
* This results in a more powerful burn, which can improve engine performance.
* The water vapor can also help to clean the engine's cylinders and injectors, which can help to reduce emissions.
* Water injection also has the potential for increasing fuel economy as the water vapor takes up space in the combustion chamber, allowing less fuel to be used to create the same amount of pressure and power.
Water injection was used in some aircraft engines during World War II to increase horsepower, and it is still used in some high-performance racing engines today. It is not as common in passenger cars, but there are a few aftermarket water injection kits available.
