Rochester Products Division (RPD) was a division of General Motors that manufactured carburetors, and related components including emissions control devices and cruise control systems in Rochester, New York. In 1995 Rochester became part of Delphi, which in turn became a separate company four years later,〔Thomas H. Klier, James M. Rubenstein, ''(Who really made your car?: restructuring and geographic change in the auto industry )'', Page 48, W.E. Upjohn Institute for Employment Research, 2008.〕 and continues to manufacture fuel injection systems in Rochester. ==History== The company began as the Rochester Coil Company founded by Edward A. Halbleib in 1908,〔James M. Rubenstein, ''The Changing U.S. Auto Industry: A Geographical Analysis'', Page 114, Routledge, London, 1992.〕 becoming the North East Electric Company the following year. In 1916 the company was located at 348 Whitney Street, Rochester.〔''Rochester, City of Varied Industries-1916'', The Rochester Chamber of Commerce, Page 25.〕 In 1929 Alfred P. Sloan announced the acquisition of the company on behalf of General Motors.〔''Springfield Republican'', September 22, 1929, Page 61.〕 "For some years this Company has been an outstanding manufacturer of starters, ignition systems and other electrical equipment." 〔''General Motors Corporation Annual Report, 1929'', Page 16.〕 "It was consolidated with GM's former Delco-Light Company in 1930 and later renamed Delco Appliance Division." In 1937 Rochester Products was founded, planned as a second plant for Delco Appliance, but achieving Division status by 1939.〔''Dallas Morning News'', March 5, 1958, Part 1-A, Page 5.〕 In 1953 an advertisement in ''Life'' stated: "Rochester builds original equipment carburetors for Chevrolet starting with 1950, Oldsmobile from 1949 and Cadillac from 1951. Also, Rochester supplies ''replacement'' carburetors for Chevrolets from 1932." 〔''Life'', March 30, 1953, Page 37.〕 Rochester also supplied Pontiac, while using the Power Jet name in the replacement market.〔''Oregonian'', July 25, 1951, Page 27.〕 In 1952 the ''Oregonian'' reported: "Automobile cigarette lighters produced by the Rochester Automotive products division of General Motors are tested to reach a temperature of 1400 degrees in no less than 10 and no more than 12 seconds." 〔''Oregonian'', March 16, 1952, Page 74.〕 The 2G (later 2GC and 2GV) carburetor, commonly called the 2 Jet, was introduced in 1955, and continued to be used on GM V8s until at least 1969.〔''Street Rodder'', 1/85, p.14.〕 In all, it was used in at least 125 applications, including the Brockway's inline six.〔''Street Rodder'', 1/85, p.14.〕 In 1957 Chevrolet introduced their first fuel-injected engine,〔''Springfield Union'', February 17, 1957, Page 75.〕 the Rochester Ramjet high-performance option on Corvette and passenger cars at $484.〔''Dallas Morning News'', November 22, 1956, Part 1, Page 12.〕 In 1956 Oldsmobile were also experimenting with Rochester fuel injection, at the GM desert proving grounds near Phoenix, but offered the Rochester triple-carburetor J2 option for 1957.〔''Oregonian'', November 4, 1956, Page 76.〕 The company is best known for the Quadrajet carburetor, which was originally designed in the 1960s and remained in production, with modifications to meet progressively tightening exhaust emission limits, into the 1980s. The Quadrajet became computer controlled in 1980 in California and in 1981 in the rest of the states; its last application was on the 1990 Cadillac Brougham and 1990 full size GM station wagons with the Olds 307 engine. RPD was a pioneer in fuel injection systems in road cars in the 1980s. In addition to carburetors, Rochester also made various emissions control equipment such as charcoal canisters and EGR valves, which found use in GM vehicles as well as those from other makes. Other products made at this planct were locks and keys as well as steel tubing for both vehicular and non-vehicular applications. The last major carburetor design by Rochester was the Varajet II, essentially a Quadrajet halved lengthwise, and was one of the few successful progressive 2-barrel carburetors. It was installed on 4- and 6-cylinder engines from 1979 to 1986. In 1981, Rochester Products and Diesel Equipment Division merged in what was publicly described as a cost-cutting move. At this time RPD had about 7,000 employees, and DED had about 3,300 employees.〔''Wall Street Journal'', April 27, 1981, Page 24.〕 DED had plants in Grand Rapids, Michigan. 〔(Company News; G.M. Announces Merger of 2 Units - New York Times )〕 The headquarters remained in Rochester. In 1988, the diesel fuel injection business was sold to Penske Transportation,〔''New York Times'', August 27, 1988, Page 33.〕 and Rochester Products and AC Spark Plug merged. 〔(COMPANY NEWS; G.M. Merges Units - New York Times )〕 In 1994, the Grand Rapids operations of AC Rochester were spun off.〔(SEC Info - General Motors Corp - 10-K405 - For 12/31/94 - EX-10.(B) ) (132nd Page of 162).〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Rochester Products Division」の詳細全文を読む スポンサード リンク
