A V6 engine is a six-cylinder piston engine where the cylinders share a common crankshaft and are arranged in a V configuration.
The Pontiac V8 engine is a family of overhead valve V8 engines manufactured by the Pontiac Division of General Motors Corporation that made its debut in 1955. Pontiac began as a "companion" to the Oakland division of the General Motors line of automobiles in 1926. Pontiac successfully competed against more-expensive inline four-cylinder models with their inline flathead six-cylinder engines. After outselling Oakland, Pontiac became the sole survivor of the two by 1932. In addition to the inline 6, Pontiac used the Oakland V8 for one year, 1932, debuting an inline 8 in 1933. The two inline engines were used through 1954, when Pontiac unveiled its OHV V8 in 1955. The development of this V8 dates back to 1946, when engineers began considering new engine designs for postwar cars. They came up with a 269-cubic-inch (4.4 L) L-head design. Pontiac engineers tested their 269 cu in (4.4 L) V8 in 1949 or 1950 against a downsized Olds rocket V8 overhead engine. The Olds engine was a 303 cu in (5.0 L), Pontiac reduced the size to 270 cu in (4.4 L) in for testing against the 269 engine. The test results showed Pontiac that an L-head engine simply couldn't compete with overhead valve V8 engine designs.
After an early flirtation with V-twin engines, Mazda's small cars of the 1960s were powered by OHV straight-2 and straight-4 engines. This family lasted from 1961 until the mid-1970s. Today, Mazda's keicars use Suzuki engines. It was produced at the Hiroshima Plant in Hiroshima, Japan.
The Oldsmobile V8, also referred to as the Rocket, is series of engines that was produced by Oldsmobile beginning in 1949. The Rocket, along with the 1949 Cadillac V8, were the first post-war OHV crossflow cylinder head V8 engines produced by General Motors. Like all other GM divisions, Olds continued building its own V8 engine family for decades, adopting the corporate Chevrolet 350 small-block and Cadillac Northstar engine only in the 1990s. All Oldsmobile V8s were manufactured at plants in Lansing, Michigan.
The Ferrari Dino engine is a line of mechanically similar V6 and V8 engines produced by Ferrari for about 40 years from the late 1950s into the early 2000s.
The Ferrari Colombo Engine was a petrol fueled, water cooled, carburetted 60° V12 engine designed by Gioacchino Colombo and produced in numerous iterations by Italian automaker Ferrari between 1947 and 1988. The maker's first homegrown engine, its linear successor is the Lampredi V12.
The Lancia Aurelia is a car produced by Italian manufacturer Lancia from 1950 to the summer of 1958. It is noted for using one of the first series-production V6 engines. Several body styles were offered: 4-door saloon, 2-door GT coupé (B20), 2-door spider/convertible (B24), and a chassis to be custom bodied by external coachbuilders.
Austin Motor Company's small straight-4 automobile engine, the A series, is one of the most common in the world. Launched in 1951 with the Austin A30, production lasted until 2000 in the Mini. It used a cast-iron block and cylinder head, and a steel crankshaft with 3 main bearings. The camshaft ran in the cylinder block, driven by a single-row chain for most applications, and with tappets sliding in the block, accessible through pressed steel side covers for most applications, and with overhead valves operated through rockers. The cylinder head for the overhead-valve version of the A-series engine was designed by Harry Weslake – a cylinder head specialist famed for his involvement in SS (Jaguar) engines and several F1-title winning engines. Although a "clean sheet" design, the A series owed much to established Austin engine design practise, resembling in general design and overall appearance a scaled-down version of the 1200cc overhead-valve engine first seen in the Austin A40 Devon which would form the basis of the later B-series engine.
Italian automobile company Lancia was the first to manufacture cars with V4 and V6 engines in series-production. This started with a number of V4-engine families, that were produced from the 1920s through 1970s.
The Lincoln Y-block V8 engine was Ford's earliest OHV V8 engine, introduced by Lincoln in the 1952 model year. Like the later and better-known but even more short-lived Ford Y-block engine, its block's deep skirts gave the block the appearance of the letter Y from the front.
The Prince G-series engine was the company's only straight-four and straight-six engines which began production in 1955. A number of variations were made, with both OHV and OHC heads. A diesel four-cylinder with 1.9 L (1,862 cc) was also built, called the D-6. The G series was used in the Skyline, the Laurel, and the Gloria from the 1950s to the early 1970s.
The Lancia Flat-4 engine is an aluminum, pushrod flat-four (boxer) engine made by Lancia for the Flavia from 1960 through 1984. Though it was a pushrod engine, it was advanced for the time. The pushrod version of the Lancia boxer was only ever used in the Flavia, and its derivatives including the Lancia 2000. In 1976, a new overhead cam engine based on a similar layout was designed and brought into production in 2 and 2.5-litre displacements for the Gamma.
The Chrysler Hemi engines, known by the trademark Hemi, are a series of I6 and V8 gasoline engines built by Chrysler with hemispherical combustion chambers. Three different types of Hemi engines have been built by Chrysler for automobiles: the first from 1951 to 1958, the second from 1964 to 1971, and the third beginning in 2003. Although Chrysler is most identified with the use of "Hemi" as a marketing term, many other auto manufacturers have incorporated similar designs.
In a reciprocating piston engine, the stroke ratio, defined by either bore/stroke ratio or stroke/bore ratio, is a term to describe the ratio between cylinder bore diameter and piston stroke length. This can be used for either an internal combustion engine, where the fuel is burned within the cylinders of the engine, or external combustion engine, such as a steam engine, where the combustion of the fuel takes place outside the working cylinders of the engine.
The Lancia Flaminia is a luxury car produced by Italian automaker Lancia from 1957 to 1970. It was Lancia's flagship model at that time, replacing the Aurelia. It was available throughout its lifetime as saloon, coupé and cabriolet. The Flaminia coupé and convertible were coachbuilt cars with bodies from several prestigious Italian coachbuilders. Four "presidential" stretched limousine Flaminias were produced by Pininfarina for use on state occasions.
The Alfa Romeo V6 engine was a 60° V6 engine made by Alfa Romeo from 1979 to 2005. It was developed in the early 1970s by Giuseppe Busso, and used on the Alfa 6 with a displacement of 2.5 L (2,492 cc) and a SOHC 12-valve cylinder head. Later versions ranged from 1,997 to 3,195 cc and had DOHC 24-valve valvetrains. The original design had short pushrods for the exhaust valves in a design similar to earlier Lancia Fulvia engines. The first DOHC version was in the 1993 Alfa Romeo 164, with an aluminium alloy engine block and head with sodium filled exhaust valves.
The Chevrolet 153 cu in engine was an inline-four engine designed in the early 1960s for use in the Chevy II. It is a four-cylinder variant of the third generation Chevrolet straight-six. After 1970 GM ceased production of the 153 engine in North America because of low demand, but the engine continued to be used in cars in other markets around the world, notably South Africa and Brazil. The engine was also standard equipment in the Jeep DJ-5A—used by the United States Postal Service—until American Motors bought Kaiser Jeep in 1970 and replaced the engine with the AMC straight-six in the DJ-5B. Currently descendants of the 153 engine are used in industrial and marine applications. The 153 engine is entirely different from the 151 cu in (2.5 L) Iron Duke engine introduced by Pontiac in 1977, most noticeably never having featured the Pontiac engine's crossflow cylinder head, but the two are often confused today.
Nissan's sidevalve engines were based on the Austin 7 engine, with which they shared the 76 mm (2.99 in) stroke. The series began with a 495 cc iteration for the 1930 Datson Type 10 and ended with the 860 cc Type 10 engine which was built until 1964 for light commercial vehicles. Later versions were called the B-1.
