I have seen water injection factory installed on farm tractors built between 1910 and 1915 using the cooling system as the water source. They in general were manual control and instructions on a placard generally referred to temporary use to stop knocking when needed. Compression ratio's of 4:1 were the norm at that time with higher compression not generally seen until in the late 20's/early 30's with optional compression ratios of up to 6:1 available in cars. Also the development of Ethyl or high test gasoline encouraged higher compression ratios. It was not uncommon to run an early Tractor on either Gasoline of Kerosene of the time with no changes other than filling the tank with different products. The Olds compact of the early 60's with the 215 Aluminum V8 turbocharged was factory equipped with H20/Alcohole injection as were a couple of other interesting autos of the period. A web search using the phrase Water Injection showed up 547,000 web sites so there is plenty of data out there on this fascinating and ageless subject.
