Pontiac Straight-6 Engine
The Pontiac straight-6 engine is a family of inline-six cylinder automobile engines produced by the Pontiac Division of General Motors Corporation in numerous versions beginning in 1926. "Split Head" Six 186 In the 1920s Oakland Motor Car engineers designed an all new engine for their "companion" make, the Pontiac, that was introduced in 1926. It was a side-valve design with a one piece cast iron block with three main bearings. An unusual feature was that it had two separate cylinder heads that each covered three cylinders. The ignition distributor was mounted on top of the block in the gap between the heads. This engine was also used in GMC's T-10 and T-11 (their two lightest trucks) beginning in 1928. Development of the engine shared characteristics with the Oldsmobile Straight-6 engine, as GM worked together to develop the engine for Pontiac combined with the resources of GM-Northway Motor and Manufacturing Division. This engine displaced with a bore and stroke of and was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chevrolet Turbo-Thrift Engine
The Chevrolet Turbo-Thrift engine is a straight-six produced from 1962 to 2001 by the Chevrolet Division of General Motors. The entire series of engines was commonly called ''Turbo-Thrift'', although the name was first used on the 230 cubic inch version that debuted in 1963. The new engine featured seven main bearings in lieu of the four bearing design of its predecessor, the "Stovebolt" engine, and was considerably smaller and approximately 100 lbs lighter. There were other major differences between the Turbo-Thrift engine and the Stovebolt: *Bore spacing matches the Chevrolet small-block V8's 4.4 inches, *Stroke of the 194 and 230 engines is the same as the 327 small-block and 348 big-block V8s *Wedge-type "closed chamber" cylinder heads with a "squish" area surrounding the combustion chamber cavity, *Stamped ball-pivot stud-mounted rocker arms were introduced, similar to the V8, with a 1.75:1 ratio, rather than the earlier shaft-mounted 1.477:1 rockers. The first use of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pontiac Tempest
The Pontiac Tempest is an automobile that was produced by Pontiac from 1960 to 1970, and again from 1987 to 1991. The Tempest was introduced as an entry-level compact in October 1960 at the Paris Auto Show for the 1961 model year. An innovative design, it shared the new unibody Y platform, GM's first, with the Buick Special/Skylark and Oldsmobile F-85/Cutlass, and featured the "Trophy-4" four-cylinder engine with a flexible drive shaft to a two-speed rear-mounted transaxle automatic transmission. The line offered the optional LeMans trim upgrade, beginning with a few 1961 LeMans coupes and adding a performance aspect in 1962. By 1964 the Tempest, Tempest Custom and Lemans are separate trim packages on the updated GM A-body platform, and the GTO was a performance option upgrade to the LeMans for 1964 and 1965. The GTO was offered as a separate model line beginning in 1966. In Canada, Pontiac also marketed a rebadged version of the compact L-body Chevrolet Corsica under the n ...

Pontiac (automobile)
Pontiac or formally the Pontiac Motor Division of General Motors, was an American automobile brand owned, manufactured, and commercialized by General Motors. Introduced as a General Motors companion make program, companion make for GM's more expensive line of Oakland Motor Car Company, Oakland automobiles, Pontiac overtook Oakland in popularity and supplanted its parent brand entirely by 1933. Sold in the United States, Canada, and Mexico by GM, in the hierarchy of GM's five divisions, it was slotted above Chevrolet, but below Oldsmobile, Buick, and Cadillac. Starting with the 1959 models, marketing was focused on selling the lifestyle that the car's ownership promised rather than the car itself. By emphasizing its "Wide Track" design, it billed itself as the "performance" division of General Motors, which "built excitement." Facing financial problems and restructuring efforts, GM announced in 2008 financial crash, 2008 that it would follow the same path with Pontiac as it had ...

Exhaust Manifold
In automotive engineering, an exhaust manifold collects the exhaust gases from multiple cylinders into one pipe. The word ''manifold'' comes from the Old English word ''manigfeald'' (from the Anglo-Saxon ''manig'' anyand ''feald'' old and refers to the folding together of multiple inputs and outputs (in contrast, an inlet or intake manifold ''supplies'' air ''to'' the cylinders). Exhaust manifolds are generally simple cast iron or stainless steel units which collect engine exhaust gas from multiple cylinders and deliver it to the exhaust pipe. For many engines, there are aftermarket tubular exhaust manifolds known as headers in American English, as extractor manifolds in British and Australian English,''The Design and Tuning of Competition Engines'', Philip H. Smith, pp. 137–138 and simply as "tubular manifolds" in British English. These consist of individual exhaust headpipes for each cylinder, which then usually converge into one tube called a collector. Headers that do n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pontiac Firebird
The Pontiac Firebird is an American automobile that was built and produced by Pontiac from the 1967 to 2002 model years. Designed as a pony car to compete with the Ford Mustang, it was introduced on February 23, 1967, five months after GM's Chevrolet division's platform-sharing Camaro. This also coincided with the release of the 1967 Mercury Cougar, Ford's upscale, platform-sharing version of the Mustang. The name "Firebird" was also previously used by GM for the General Motors Firebird in the 1950s and early 1960s concept cars. First generation (1967–1969) The first generation Firebird had characteristic Coke bottle styling shared with its cousin, the Chevrolet Camaro. Announcing a Pontiac styling trend, the Firebird's bumpers were integrated into the design of the front end, giving it a more streamlined look than the Camaro. The Firebird's rear "slit" taillights were inspired by the 1966–1967 Pontiac GTO and Pontiac Grand Prix. Both a two-door hardtop and a conver ...

Pontiac LeMans
The Pontiac LeMans is a model name that was applied to subcompact- and intermediate-sized automobiles marketed by Pontiac from 1961 to 1981 (1983 in Canada) model years. Originally a trim upgrade based on the Tempest, it became a separate model. In 1964 the Tempest was available with an optional GTO package that later became a separate model, the Pontiac GTO, muscle car. 1970 introduced the GT-37 package. Manufactured in five generations in the 1960s and 1970s, it was replaced by the downsized Pontiac Grand Am. From 1988 to 1993 the name was resurrected for a badge-engineered version of the Daewoo LeMans manufactured by Daewoo in South Korea. It is named for the French city of Le Mans which has been the site of the 24 Hours of Le Mans, the world's oldest active endurance sports car race since it began in 1923. First generation (1961–1963) 1961 The LeMans was introduced as the top trim package of the compact-sized Pontiac Tempest toward the end of the 1961 model year o ...

Jeep Tornado Engine
The Jeep Tornado engine was the first post-World War II U.S.-designed mass-produced overhead cam (OHC) automobile engine. The straight-six was introduced in mid-year 1962, and replaced the flathead 6-226 Willys Super Hurricane that was in use since 1954. The Tornado engine was also manufactured in Argentina by Industrias Kaiser Argentina (IKA) from 1965 to 1973. History The development of a new engine for Kaiser Jeep for an entirely new vehicle began under Chief Engineer, A.C. "Sammy" Sampietro, in the late-1950s. Sampietro worked under Donald Healey in Europe and focused on improving power output through better engine breathing. The single overhead cam design was combined with hemispheric combustion chambers. Mass production of the new engine began in 1962. The Jeep Tornado engine was introduced in the Willys Jeep Wagon and truck models. Six-cylinder versions built after 3 May 1962, received the 230 OHC "Tornado" engine, replacing the 226 L-head "Super Hurricane" I6. It ...

Single Overhead Camshaft
An overhead camshaft (OHC) engine is a piston engine where the camshaft is located in the cylinder head above the combustion chamber. This contrasts with earlier overhead valve engines (OHV), where the camshaft is located below the combustion chamber in the engine block. ''Single overhead camshaft'' (SOHC) engines have one camshaft per bank of cylinders. ''Dual overhead camshaft'' (DOHC, also known as "twin-cam".) engines have two camshafts per bank. The first production car to use a DOHC engine was built in 1910. Use of DOHC engines slowly increased from the 1940s, leading to many automobiles by the early 2000s using DOHC engines. Design In an OHC engine, the camshaft is located at the top of the engine, above the combustion chamber. This contrasts the earlier overhead valve engine (OHV) and flathead engine configurations, where the camshaft is located down in the engine block. The valves in both OHC and OHV engines are located above the combustion chamber; however an OHV en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flywheel
A flywheel is a mechanical device which uses the conservation of angular momentum to store rotational energy; a form of kinetic energy proportional to the product of its moment of inertia and the square of its rotational speed. In particular, assuming the flywheel's moment of inertia is constant (i.e., a flywheel with fixed mass and second moment of area revolving about some fixed axis) then the stored (rotational) energy is directly associated with the square of its rotational speed. Since a flywheel serves to store mechanical energy for later use, it is natural to consider it as a kinetic energy analogue of an electrical inductor. Once suitably abstracted, this shared principle of energy storage is described in the generalized concept of an accumulator. As with other types of accumulators, a flywheel inherently smooths sufficiently small deviations in the power output of a system, thereby effectively playing the role of a low-pass filter with respect to the mechanical velocity ...

Overhead Valve
An overhead valve (OHV) engine, sometimes called a ''pushrod engine'', is a piston engine whose valves are located in the cylinder head above the combustion chamber. This contrasts with earlier flathead engines, where the valves were located below the combustion chamber in the engine block. Although an overhead camshaft (OHC) engine also has overhead valves, the common usage of the term "overhead valve engine" is limited to engines where the camshaft is located in the engine block. In these traditional OHV engines, the motion of the camshaft is transferred using pushrods (hence the term "pushrod engine") and rocker arms to operate the valves at the top of the engine. Some early intake-over-exhaust engines used a hybrid design combining elements of both side-valves and overhead valves. History Predecessors The first internal combustion engines were based on steam engines and therefore used slide valves. This was the case for the first Otto engine, which was first succ ...
