of Julius Hock & Co of Vienna

1873 Julius Hock patented an internal combustion engine using volatile petroleum as fuel and having flame ignition. Built for a limited period, Lyle Cummins stated that its unreliability and danger, plus the introduction of the Otto 4-stroke cycle 'quickly ended its tenuous existence'. [1]

Hock & Co also produced hot air engines (Feuerluftmaschine) in Vienna. An 1878 example is on display in Vienna Technical Museum.
