What is water injection in a BMW?
BMW’s water-injection system—which is supplied by Bosch and available to other automakers—sprays cold water into the intake plenum via three injectors. The water immediately evaporates into the air in the manifold, reducing intake air temperature and increasing the air density.
What does water injection do to a car?
In internal combustion engines, water injection, also known as anti-detonant injection (ADI), can spray water into the incoming air or fuel-air mixture, or directly into the combustion chamber to cool certain parts of the induction system where “hot points” could produce premature ignition.
Does M4 GTS have water injection?
The BMW M4 GTS is the first production road car to be fitted with an innovative and trailblazing water injection system.
Does water injection increase mpg?
If you’re reluctant to tackle piston replacement, you can still enjoy an approximately 20% MPG improvement by installing a water injection system on your stock engine.

Will methanol hurt my engine?
Methanol will destroy the aluminum in your engine by causing it to oxidize, or basically rust. Methanol does this by destroying the aluminum-oxide coating on the surface of the aluminum, this causes the aluminum to oxidize again once exposed to oxygen and form a new layer of aluminum-oxide…. over and over again.
Does water injection improve fuel economy?
Particularly when accelerating quickly or driving on the freeway, the injection of additional water makes it possible to reduce fuel consumption by as much as 13 percent in highway conditions and four percent in normal driving.
Who invented water injection?
H. Ricardo
Water injection was evaluated scientifically in the 1930’s by H. Ricardo who demonstrated that one can basically double the power output of an engine using water/methanol. The first widespread use was during WWII on supercharged and turbocharged aircraft.
