The Hornsby-Ackroyd Safety Oil Engine was a range of engines built by Richard Hornsby & Sons to the designs of Herbert Akroyd Stuart that opperated on Paraffin(heavy oil) rather than the more volatile Petrol. These engines used a vapouriser initial to assist combustion. To start the engines the head is headed (now days using a propane blow torch). but the design evoled to do away with the vapouriser and just use the compresion (but less than a diesel engine).

Hornsby started building the Oil Engines' in 1892. and by 1896 had built 3 Hornsby-Ackroyd Safety Oil Engine tractors, which went to Australia. Two survive with one in the UK and the other still in in Australia were it has been restored (2009).
