He studied the Lenoir motor in Paris in 1874 and there he recognized the prospects of the internal combustion engine. He became head of the training workshop at the Technical University of Budapest at the age of 25 where he employed skilled workers at his own expense, which allowed him to use the workshop for his experiments. Csonka retired at the age of 73 and filed his last patent application at the age of 84.
