Ford’s German division has filed a patent for a new water injection system that could bring exponential improvements in efficiencies and high horsepower gains.

Truthfully, water injection isn’t a new technology, World War II fighter planes used vaporized water to improve low-speed thrust during take off, plus, an extra spurt of speed during dogfights. Post-war, both Saab and Oldsmobile offered vehicles with factory installed water injection systems before the technology enjoyed a renaissance in high-performance Group B rally cars during the 1980s.

Traditionally, water injection has been used as a shortcut to high performance, where a 50/50 water-alcohol mix is injected into the intake manifold where it’s used to lower combustion temperatures and cool the pistons and cylinder walls. This, in turn, reduces the likelihood of detonation and allows for higher compression ratios, which can manifest as either higher performance metrics or a more efficient engine.

But where Ford’s design differs is its focus on injecting water directly into the combustion chamber instead of its traditional upstream location in the intake tract. (Read More…)

Bosch, the creator of the horsepower-boosting water injection system in the BMW M4 GTS, will now offer the technology to any automaker that wants it.

Spraying distilled water vapor into an engine’s combustion chamber has an added bonus of greatly increasing fuel efficiency — meaning Bosch might have a lineup at its door when the system enters mass production in 2019, Autocar reports. (Read More…)
