Crown Supercoach
The Crown Supercoach is a bus that was constructed and marketed by Crown Coach Corporation from 1948 to 1991. While most examples were sold as yellow school buses, the Supercoach formed the basis for motorcoaches and other specialty vehicles using the same body and chassis. While technically available outside of the West Coast, nearly all Crown school buses were sold in Washington state, Oregon and California. From 1948 to 1984, the Supercoach was constructed at the Crown Coach facilities in Los Angeles, California; from 1984 to the 1991 closure of the company, the Supercoach was constructed in Chino, California. Design history 1932–1948 In 1932, Crown Motor Carriage Company built its first complete school bus, in a shift from building bus bodies on cowled truck chassis. Externally modeled after Twin Coach body designs, the school bus body used a front-engine layout, with the Waukesha gasoline engine positioned next to the driver. The body was of all-metal construction with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crown Coach Corporation
The Crown Coach Corporation (founded as the Crown Carriage Company) is a defunct American bus manufacturer. Founded in 1904, the company was best known for its Supercoach range of yellow school buses and motorcoaches; the former vehicles were marketed throughout the West Coast of the United States. Competing alongside Gillig Corporation and similar its Gillig Transit Coach, the two companies supplied California with school buses nearly exclusively into the 1980s. Crown also was the manufacturer of custom-built vehicles derived from its buses, including the Firecoach line of fire apparatus. For 80 years, Crown was headquartered in Los Angeles, California; in 1984, the company relocated its headquarters and manufacturing to Chino, California, where it operated until its closure. In March 1991, Crown Coach (then a subsidiary of GE Railcar) ended operations as a result of declining demand for school buses at the time. History 1904–1920: Wagons to school buses At the ...

Cummins C Series Engine
The Cummins C Series engine is a straight-six diesel engine with a displacement of . Cummins began producing the engines in 1998. The engine was based on its predecessor, the Cummins C 8.3-litre engine originally introduced in 1985 as the 6C8.3 (this was co-designed with the Case Corporation, along with the smaller 6B5.9). The first electronic version, known as the ''C8.3E'' and designed for the urban bus market exclusively, went into production in late 1996. By late 2003, Cummins announced that they will revise the engine to sport a High-Pressure Common-Rail (HPCR) system to help with emissions and also a variable geometry turbocharger system to help with the performance on this engine. The Cummins ISC also has a sister engine which is designed off the existing ISC 8.3-litre cylinder block which runs on compressed natural gas (CNG). Cummins reintroduced this engine as the C PLUS engine which has a maximum power rating of . A few thousand units of this engine are now roami ...

Ford Super Duty Engine
The Ford Super Duty engine is a range of V8 engines that were manufactured by Ford Motor Company. Introduced in 1958, the Super Duty engines replaced the Lincoln Y-block V8 (alongside the smaller Ford MEL V8 engines). By the end of the 1970s, the use of the Super Duty engine began to decline in heavy trucks in favor of diesel-fueled engines; in medium-duty trucks, variants of the similar-displacement (but higher-efficiency) 385-series V8s became more commonly used. In 1981, Ford withdrew the Super Duty engine line. Through its production, the Super Duty engines were assembled by Ford in its Cleveland Engine Plant #2 in Brook Park, Ohio. Design The Super Duty engine is 90-degree overhead-valve V8 with angled piston decks. The cylinder heads are flat and the pistons are crowned to create a wedge-shaped combustion chamber within the cylinder bore; the compression ratio is 7.5:1 for all models. They are typically governed to 3400 rpm. Three displacements were available duri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hall-Scott
Hall-Scott Motor Car Company was an American manufacturing company based in Berkeley, California. It was among the most significant builders of water-cooled aircraft engines before World War I. History 1910–21 The company was founded in 1910 by Californians Elbert J. Hall and Bert C. Scott to manufacture engines for automobiles and later expanded the production of engines for trucks and airplanes as well as gasoline-powered rail cars and locomotives. Hall was a mechanic and engine builder and Scott, Stanford University-educated, was the business executive. They produced their first rail car in 1909, which they sold to the Yreka Railroad. In 1910, a factory was opened in Berkeley, California, with headquarters for a short time in San Francisco. The company built interurban electric railway cars for railroads such as the electrified Sacramento Northern, which ran trains from adjacent Oakland to Sacramento and Chico. The rail car business was slow, but some were sold as far awa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carpenter Body Company
Carpenter Body Works (typically referred to simply as Carpenter) is a defunct American bus manufacturer. Founded in 1918 in Mitchell, Indiana, the company produced a variety of vehicles, with the majority of production consisting of yellow school buses for the United States and Canada.

Crown Supercoach II
A crown is a traditional form of head adornment, or hat, worn by monarchs as a symbol of their power and dignity. A crown is often, by extension, a symbol of the monarch's government or items endorsed by it. The word itself is used, particularly in Commonwealth countries, as an abstract name for the monarchy itself, as distinct from the individual who inhabits it (that is, ''The Crown''). A specific type of crown (or coronet for lower ranks of peerage) is employed in heraldry under strict rules. Indeed, some monarchies never had a physical crown, just a heraldic representation, as in the constitutional kingdom of Belgium, where no coronation ever took place; the royal installation is done by a solemn oath in parliament, wearing a military uniform: the King is not acknowledged as by divine right, but assumes the only hereditary public office in the service of the law; so he in turn will swear in all members of "his" federal government''.
