4. Now read and translate the text paying attention to the words in italics History of the Internal Combustion Engine In 1680 a Dutch physicist, Christian Huygens designed (but never built) an internal combustion engine. In 1807 de Rivaz invented an internal combustion engine that used coal gas as a fuel. Rivaz designed a car for his engine – the first internal combustion powered automobile. In 1860 the first internal combustion engine for commercial use was built by Etienne Lenoir. Although this engine had a thermal efficiency of only 4%, hundreds of engineswere used. A few years later, a Frenchman, de Rochas, proposed the operation of a four-stroke-cycle engine which is used in present-day automobiles. The next development in the history of the internal combustion engine came in 1866 when Nikolaus Otto invented a more efficient gas engine. In 1876 Otto invented and patented a four-stroke engine, known as the “Otto cycle engine”.
