Ralph Tony Sarich (born 10 December 1938 in Baskerville, Western Australia) is an Australian automotive engineer, inventor, and businessman who developed the orbital engine and the orbital combustion process engine. Sarich founded the Orbital Engine Company, which developed the orbital combustion process (OCP) engine, based on the two-stroke concept. Early life Sarich was born on 10 December 1938, in Baskerville, Western Australia to an Austrian and Croatian family. His parents arrived in Australia before the Great Depression of the 1930s. Sarich began an apprenticeship as a fitter and turner, studying high school years 11 and 12 subjects part-time at Midland Technical School. He qualified with top achievement at the completion of his apprenticeship, during and after which he did engineering units one day per week, night classes, and by correspondence. Career His working career encompassed being a fitter and turner and trainee engineer with the Western Australian Government Railways between 1954 and 1963. He was plant engineer with Thiess Brothers between 1963 and 1965, in charge on the standard gauge project before running his own business, an engineering and service station operator. Sarich was sales engineer as well as investor in the area of earth moving and industrial machinery before being regional general manager and an investor. As he developed the orbital engine, he became managing director of Orbital Engine Company Pty Ltd, and chief executive officer and chairman of Orbital Engine Corporation. Following his retirement from Orbital, he became Executive Chairman of Cape Bouvard Investments, a private family investment company. Orbital engine Sarich concentrated on research and development of new technologies, in particular the orbital engine. The engine was first fired in 1972 and Sarich appeared on ABC TV program The Inventors in 1972 claiming that the engine's compact design promised more power, fewer emissions and significant fuel economy. The technology was endorsed by the Royal Automobile Club of Western Australia in 1974: The "staged combustion" process was later named as the orbital combustion process (OCP). There were two distinct orbital concepts; the OCP technology and the orbital engine hardware that converted the resultant combustion energy to mechanical output to drive vehicles. Under simulated urban and highway driving cycles it produced fuel and emission results superior to the best selected engines of the era. This was due to the OCP, often wrongly referred to as the fuel injection system because of its vital role in this technology. As the
