Pontiac Trophy 4 Engine
The Pontiac Trophy 4 engine (also called the ''Indianapolis 4'', or ''Indy 4'') is a inline four-cylinder engine produced by the Pontiac Motor Division of General Motors for model years 1961 through 1963. Created from one bank of Pontiac's powerful '' Trophy V8'', its only application was in the first generation Pontiac Tempest. It was dubbed by Pontiac the ''Trophy 4'', playing off the racing success that had earned the 389 V8 engine the nickname ''Trophy V-8'' after just two years of competition. History The Trophy 4 engine is a short-stroke, 45-degree inclined inline four created from the right bank of the 389 V8 for the debut of the Tempest in 1961. Its displacement is precisely half of the 389, with an identical bore and stroke of . It shared most of the 389's tooling and up to 120 of its parts. This degree of commonality enabled it to be produced on the same lines as the V8, allowing substantial cost savings. The Trophy 4 weighs about , as compared to the V8 it was b ...

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 companion make for GM's more expensive line of 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 that it would follow the same path with Pontiac as it had with Oldsmobile in 2004. It would discontinue manufacturing and marketing vehicle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drivetrain
A drivetrain (also frequently spelled as drive train or sometimes drive-train) is the group of components that deliver mechanical power from the prime mover to the driven components. In automotive engineering, the drivetrain is the components of a motor vehicle that deliver power to the drive wheels. This excludes the engine or motor that generates the power. In marine applications, the drive shaft will drive a propeller, thruster, or waterjet rather than a drive axle, while the actual engine might be similar to an automotive engine. Other machinery, equipment and vehicles may also use a drivetrain to deliver power from the engine(s) to the driven components. In contrast, the powertrain is considered to include both the engine and/or motor(s) as well as the drivetrain. Function The function of the drivetrain is to couple the engine that produces the power to the driving wheels that use this mechanical power to rotate the axle. This connection involves physically linking the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pontiac V8 Engine
The Pontiac V8 engine is a family of overhead valve 90° V8 engines manufactured by the Pontiac Division of General Motors Corporation between 1955 and 1981. The engines feature a cast-iron block and head and two valves per cylinder. Engine block and cylinder heads were cast at Saginaw Metal Casting Operations then assembled at Tonawanda Engine before delivery to Pontiac Assembly for installation. Initially marketed as a , it went on to be manufactured in displacements between and in carburated, fuel injected, and turbocharged versions. In the 1960s the popular version, which had helped establish the Pontiac GTO as a premier muscle car, was cut in half to produce an unusual, high-torque inline four economy engine, the Trophy 4. Unusual for a major automaker, Pontiac did not have the customary "small-block" and "big-block" engine families common to other GM divisions, Ford, and Chrysler. Effectively, Pontiac's V8s were all small blocks, sharing the same connecting r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pontiac Straight-8 Engine
The Pontiac straight-8 engine is an inline eight-cylinder automobile engine produced by Pontiac from 1933 to 1954. Introduced in the fall of 1932 for the 1933 models, it was Pontiac's most powerful engine at the time and the least expensive eight-cylinder engine built by an American automotive manufacturer. During its 21-year run displacement of the "eight" increased twice as platforms grew. It was superseded by Pontiac's new V8, the 287, in 1955. Engine block and cylinder heads were cast at Saginaw Metal Casting Operations then assembled at Tonawanda Engine before delivery to Pontiac Assembly for installation. History The straight-8 was dubbed the ''Silver-Streak'' at Pontiac Division. Powered by the "eight", optional in lower-end models, a Pontiac was promoted as a likable automobile, with enough power under the hood to get the job done in affordable luxury. However, by the early 1950s, powerful overhead valve V8s from sister GM Divisions Cadillac, Buick and Oldsmobile, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iron Duke Engine
The Iron Duke engine (also called 151, 2500, Pontiac 2.5, and Tech IV) is a Straight-4 piston engine built by the Pontiac Motor Division of General Motors from 1977 to 1993. Thereafter GM's 2.2 L OHV 4-cylinder replaced it across the entire lineup of vehicles that offered it. Although its original purpose was to serve as Pontiac's new economy car engine, it was later adapted for use in a wide variety of applications across GM's lineup in the 1980s. Development At the time of the 1973 oil crisis the only engines Pontiac built were , , and versions of their V8 engine. Recognizing that future products would need to be smaller and more fuel-efficient, Pontiac engineers were tasked with developing a new engine that would be suitable for these future products. The engineers considered developing smaller displacement versions of the existing V8, a V6 derived from the V8, a V4 derived from the V8, and an inline-four derived from one of the cylinder banks of the V8 (in the s ...

Critical Speed
In solid mechanics, in the field of rotordynamics, the critical speed is the theoretical angular velocity that excites the natural frequency of a rotating object, such as a shaft, propeller, leadscrew, or gear. As the speed of rotation approaches the object's natural frequency, the object begins to resonate, which dramatically increases system vibration. The resulting resonance occurs regardless of orientation. When the rotational speed is equal to the numerical value of the natural vibration, then that speed is referred to as critical speed. Critical speed of shafts All rotating shafts, even in the absence of external load, will deflect during rotation. The unbalanced mass of the rotating object causes deflection that will create resonant vibration at certain speeds, known as the critical speeds. The magnitude of deflection depends upon the following: *Stiffness of the shaft and its support *Total mass of shaft and attached parts *Unbalance of the mass with respect to the axis ...

Rear Wheel Drive
Rear-wheel drive (RWD) is a form of engine and transmission layout used in motor vehicles, in which the engine drives the rear wheels only. Until the late 20th century, rear-wheel drive was the most common configuration for cars. Most rear-wheel drive vehicles feature a longitudinally-mounted engine at the front of the car. Layout The most common layout for a rear-wheel drive car is with the engine and transmission at the front of the car, mounted longitudinally. Other layouts of rear-wheel drive cars include front-mid engine, rear-mid engine, and rear-engine. Some manufacturers, such as Alfa Romeo, Lancia, Porsche (944, 924, 928) and Chevrolet (C5, C6, and C7 Corvettes), place the engine at the front of the car and the transmission at the rear of the car, in order to provide a more balanced weight distribution. This configuration is often referred to as a transaxle since the transmission and axle are one unit. History 1890s to 1960s Many of the cars built in the 19t ...

Driveshaft
A drive shaft, driveshaft, driving shaft, tailshaft (Australian English), propeller shaft (prop shaft), or Cardan shaft (after Girolamo Cardano) is a component for transmitting mechanical power and torque and rotation, usually used to connect other components of a drivetrain that cannot be connected directly because of distance or the need to allow for relative movement between them. As torque carriers, drive shafts are subject to torsion and shear stress, equivalent to the difference between the input torque and the load. They must therefore be strong enough to bear the stress, while avoiding too much additional weight as that would in turn increase their inertia. To allow for variations in the alignment and distance between the driving and driven components, drive shafts frequently incorporate one or more universal joints, jaw couplings, or rag joints, and sometimes a splined joint or prismatic joint. History The term ''driveshaft'' first appeared during the mid-19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
