<P> Various scientists and engineers contributed to the development of internal combustion engines . In 1791 2 , John Barber developed a turbine . In 1794 Thomas Mead patented a gas engine . Also in 1794 Robert Street patented an internal combustion engine , which was also the first to use liquid fuel ( gasoline ) , and built an engine around that time . In 1798 , John Stevens designed the first American internal combustion engine . In 1807 , French engineers Nicéphore ( who went on to invent photography ) and Claude Niépce ran a prototype internal combustion engine , using controlled dust explosions , the Pyréolophore . This engine powered a boat on the Saône river , France . The same year , the Swiss engineer François Isaac de Rivaz built an internal combustion engine ignited by electric spark . In 1823 , Samuel Brown patented the first internal combustion engine to be applied industrially . </P>
