Ralph Sarich

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.

His working career encompassed being a fitter and turner and trainee engineer with the Western Australian Government Railways between 1954 and 1963. He was a plant engineer with Thiess Brothers between 1963 and 1965, in charge of the standard gauge project before running his own business, The technology was endorsed by the Royal Automobile Club of Western Australia in 1974:

The "staged combustion" process was later named 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 OCP technology was used on conventional engines to improve their performance this then led to inaccurate reporting claiming that the Orbital Engine Technology had failed. However, this combination was deemed to be the most cost effective direction because it eliminated production re tooling costs, which were inhibiting factors for mass production using orbital engine hardware. Despite being offered A$12 million in 1973 for his stake in Orbital, Sarich refused to sell. BHP was an early investor in Sarich's Orbital Engine Company, taking a stake in the early 1970s that by 1989 represented 35% of the total company equity. The OCP component of the engine was described in the 1980s by the Jet Propulsion Laboratories (JPL) for NASA, as the "cutting edge of world engine technology". International emission testing laboratories confirmed the Australian results. Fuel economy advantages of 50% were demonstrated against the best outboard marine engines and 20–25% under typical automobile operating conditions. Additional savings of 5–10% were considered readily achievable with further development. The savings were accompanied by a massive reduction in the "direct engine out" of several key emissions gases. The OCP technology was sold as intellectual property (IP) to automobile, marine and motorcycle manufacturers and was incorporated in production engines to varying degrees; namely from complete systems to the improvement of their own technology, via knowledge gained from their IP purchases. All licensing payments were conditional upon the delivery of engines meeting numerous high emissions standards, fuel economies and other technical criteria. All deliveries met these criteria prior to Sarich's retirement in 1992, resulting in no dependent monetary penalties ever being incurred to that point in time. However, key components of Sarich's engine could not be cooled and others could not be readily lubricated. The engine was susceptible to overheating, and the invention was eventually deemed too impractical. In 1989, the government offered an industry support package of A$1516.5 million, which Sarich declined, and he proceeded to make arrangements to establish operations in the United States. He floated Orbital Engine Corporation in the US via an initial public offering that raised A$113.8 million in 1992 In January 1992, General Motors displayed its newest concept car called the "Ultralite", incorporating OCP technology, as its centrepiece at the Detroit International Auto Show. In April 1992, another of the world's largest automotive manufacturers signed an agreement to take a licence for OCP technology.

In 1991, it was reported that Orbital Engine Corporation entered into a licensing agreement with Fiat, an Italian car manufacturer. Despite initial interest, Czechoslovakian manufacturer, Škoda, withdrew from licensing negotiations in 1989, citing poor economic conditions in the country. Volkswagen terminated its agreement with Orbital in 1993, citing a softer European sales market.

As Orbital Engine Corporation sold its IP to manufacturers and the company did not manufacture engines, the success of Orbital was doubted. 1991 and 1992 (A$22.75m). Following his retirement from Orbital, Cape Bouvard Investments (CBI) became the main focus for Sarich in his capacity as Executive Chairman of the private family investment company; while his son Peter is responsible for operations. CBI invests in numerous fields such as property investment, property development, technology and equities.

Sarich met Patricia in 1957, and they married in September 1962. Her parents also migrated to Australia as little children from Britain after World War I. Patricia was born in Kellerberrin, Western Australia. They have two children, Peter and Jennifer (deceased). Sarich donated a considerable amount of the profits from the Orbital Corporation into the community, including commitments of approximately A$65 million to various charitable organisations, including an A$20 million gift in 2008 towards neuroscience medical research facilities in Perth.
