Internal combustion engineer pioneer Isaac de Rivaz (76) died. He designed several successful steam powered carriages, or charettes as he called them in the French language. His army experience with cannon had led him to think about using an explosive charge to drive a piston instead of steam. In 1804 he began to experiment with explosions created inside a cylinder with a piston. His first designs were for a stationary engine to power a pump. The engine was powered by a mixture of hydrogen and oxygen gases ignited to create an explosion within the cylinder and drive the piston out. The gas mixture was ignited by an electric spark in the same manner as a modern internal combustion engine. In 1806 he moved on to apply the design to what became the world’s first internal combustion engine driven automobile.
In 1807 de Rivaz placed his experimental prototype engine in a carriage and used it to propel the vehicle a short distance. This was the first vehicle to be powered by an internal combustion engine. On 30 January 1807 Isaac de Rivaz was granted patent No. 731 in Paris. A patent in the State of Valais (now Swiss) patent office also dates it to 1807.
Operating independently, the French brothers Nicéphore and Claude Niépce built an internal combustion engine called the Pyreolophore in 1807, which they used to power a boat by the reaction from a pulsed water jet. The honour of whose design was the first internal combustion engine is still debated. The Niépce patent is dated 20 July 1807.
