Porsche V8 Engine
Porsche has made a number of V8 engine, V8 gasoline engines over the last 40 years; ever since their first V8 engine debuted in the Porsche 928, in 1977. Background Porsche's V8 engine is currently in its fourth consecutive generation. July 8, 2016, marked the 40-year anniversary since their first engine rolled off the production line, in the 928. Under the hood was an engine that had never been used before; an eight-cylinder engine with a 90° V-angle, and water-cooling. 1977: First Generation Porsche began a fresh chapter in engine building with the V-engine: The eight-cylinder engine was made up of essentially all lightweight alloys. As is characteristic with Porsche, it started a new era of engine construction. This was the first time in Europe that an engine was leaving the assembly line whose cylinder linings were engraved from cast aluminum. The 4.5-liter engine had a noticeably low compression ratio of 8.5:1. This meant it would be able to use normal 91-octane gasoline wit ...

Porsche
Dr. Ing. h.c. F. Porsche AG, usually shortened to Porsche (; see below), is a German automobile manufacturer specializing in luxury, high-performance sports cars, SUVs and sedans, headquartered in Stuttgart, Baden-Württemberg, Germany. The company is owned by Volkswagen AG, a controlling stake of which is owned by Porsche Automobil Holding SE, usually shortened to Porsche SE. Porsche's current lineup includes the 718, 911, Panamera, Macan, Cayenne and Taycan. The origins of the company date to the 1930s when German Bohemian automotive engineer Ferdinand Porsche founded Porsche with Adolf Rosenberger, a keystone figure in the creation of German automotive manufacturer and Audi precursor Auto Union, and Austrian businessman Anton Piëch, who was, at the time, also Ferdinand Porsche's son in law. In its early days, it was contracted by the German government to create a vehicle for the masses, which later became the Volkswagen Beetle. After World War II, when Ferd ...

Naturally-aspirated
A naturally aspirated engine, also known as a normally aspirated engine, and abbreviated to N/A or NA, is an internal combustion engine in which air intake depends solely on atmospheric pressure and does not have forced induction through a turbocharger or a supercharger. Description In a naturally aspirated engine, air for combustion ( Diesel cycle in a diesel engine or specific types of Otto cycle in petrol engines, namely petrol direct injection) or an air/fuel mixture (traditional Otto cycle petrol engines), is drawn into the engine's cylinders by atmospheric pressure acting against a partial vacuum that occurs as the piston travels downwards toward bottom dead centre during the intake stroke. Owing to innate restriction in the engine's inlet tract, which includes the intake manifold, a small pressure drop occurs as air is drawn in, resulting in a volumetric efficiency of less than 100 percent—and a less than complete air charge in the cylinder. The density of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Connecting Rod
A connecting rod, also called a 'con rod', is the part of a reciprocating engine, piston engine which connects the piston to the crankshaft. Together with the crank (mechanism), crank, the connecting rod converts the reciprocating motion of the piston into the rotation of the crankshaft. The connecting rod is required to transmit the compressive and tensile forces from the piston. In its most common form, in an internal combustion engine, it allows pivoting on the piston end and rotation on the shaft end. The predecessor to the connecting rod is a mechanic linkage used by water mills to convert rotating motion of the water wheel into reciprocating motion. The most common usage of connecting rods is in internal combustion engines or on steam engines. __TOC__ Origins A connecting rod crank has been found in the Celtic Oppida at Paule in Brittany, dated to 69 BC. The predecessor to the connecting length is the Linkage (mechanical), mechanical linkage used by List of Roman wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flat-plane Crank
The flat-plane crank (sometimes flatplane) is a type of crankshaft for use in internal combustion engines that has a 180-degree angle between crank throws. Details Flat-plane cranks are used in V-configuration engines, generally with eight cylinders. Cadillac introduced a V8 flat-plane crank engine in 1923. Inline-four cylinder engines almost all use flat-plane cranks, and thus are not usually identified as such. However, there are a few exceptions with crossplane cranks. The flat-plane crankshaft was used in the World War II Sherman Tank in the Ford GAA engine, an all-aluminium 32-valve DOHC 60-degree liquid-cooled V8. However, the flat-plane design is no longer widely used in most mass production V engines as it is more prone to vibration and is inherently much louder than a crossplane crankshaft. However, due to its simpler construction requiring less counterweight, it is inherently lighter with a higher rev limit. For this reason, it remains useful in sports ...

Street-legal Vehicle
Street-legal, road-legal, or road-going, refers to a vehicle such as a car, motorcycle, or light truck that is equipped and licensed for use on public roads, being therefore Roadworthiness, roadworthy. This will require specific configurations of lighting, signal lights, and safety equipment. Some specialty vehicles that will not be operated on roads, therefore, do not need all the features of a street-legal vehicle; examples are a vehicle used only off-road (such as a sandrail) that is Trailer (vehicle), trailered to its off-road operating area, and a Auto racing, racing car that is used only on closed race tracks and therefore does not need all the features of a street-legal vehicle. As well as motor vehicles, the street-legal distinction applies in some jurisdictions to track bicycles that lack street-legal brakes and lights. Street-legality rules can even affect racing helmets, which possess visual fields too narrow for use on an open road without the risk of missing a fast-mo ...

Hybrid Vehicle Drivetrain
Hybrid vehicle drivetrains transmit power to the driving wheels for hybrid vehicles. A hybrid vehicle has multiple forms of motive power, and can come in many configurations. For example, a hybrid may receive its energy by burning gasoline, but switch between an electric motor and a combustion engine. A typical powertrain includes all of the components used to transform stored potential energy. Powertrains may either use chemical, solar, nuclear or kinetic energy for propulsion. The oldest example is the steam locomotive. Modern examples include electric bicycles and hybrid electric vehicles, which generally combine a battery (or supercapacitor) supplemented by an internal combustion engine (ICE) that can either recharge the batteries or power the vehicle. Other hybrid powertrains can use flywheels to store energy. Among different types of hybrid vehicles, only the electric/ICE type is commercially available as of 2017. One variety operated in parallel to provide power from both ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electric Motor
An electric motor is a machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a electromagnetic coil, wire winding to generate Laplace force in the form of torque applied on the motor's shaft. An electric generator is mechanically identical to an electric motor, but operates in reverse, converting mechanical energy into electrical energy. Electric motors can be powered by direct current (DC) sources, such as from batteries or rectifiers, or by alternating current (AC) sources, such as a power grid, Inverter (electrical), inverters or electrical generators. Electric motors may also be classified by considerations such as power source type, construction, application and type of motion output. They can be brushed motor, brushed or brushless motor, brushless, single-phase electric power, single-phase, two-phase electric power, two-phase, or three-phase electric p ...

Grand Tourer
A grand tourer (GT) is a type of car that is designed for high speed and long-distance driving with performance and luxury. The most common format is a Front-engine, rear-wheel-drive layout, front-engine, rear-wheel-drive two-door coupé with either a two-seat or a 2+2 (car body style), 2+2 arrangement. Grand tourers are often the coupé derivative of Luxury vehicle, luxury saloon (car), saloons or sedans. Some models, such as the Ferrari 250 GT, Jaguar E-Type, and Aston Martin DB5, are considered classic examples of ''gran turismo'' cars. The term is a near-calque from the Italian language phrase ''gran turismo'', which became popular in the English language in the 1950s, evolving from fast touring cars and Streamliner, streamlined closed sports cars during the 1930s. Origin in Europe The grand touring car concept originated in Europe in the early 1950s, especially with the 1951 introduction of the Lancia Aurelia, Lancia Aurelia B20 GT, and features notable luminaries of Ital ...

New European Driving Cycle
The New European Driving Cycle (NEDC) was a driving cycle, last updated in 1997, designed to assess the emission levels of car engines and fuel economy in passenger cars (which excludes light trucks and commercial vehicles). It is also referred to as MVEG cycle (Motor Vehicle Emissions Group). The NEDC, which is supposed to represent the typical usage of a car in Europe, is repeatedly criticised for delivering economy-figures which are unachievable in reality. It consists of four repeated ECE-15 urban driving cycles (UDC) and one Extra-Urban driving cycle (EUDC). The WLTP test cycle replaced NEDC for vehicles approved for sale in Europe after September 2018, and all published figures for vehicles on sale after January 2019 should use WLTP fuel economy figures The NEDC test procedure is defined in UNECE R101 for the measurement of and fuel consumption and/or the measurement of electric energy consumption and electric range in hybrid and fully electric M1 and N1 vehicles, ...

Direct Fuel Injection
Fuel injection is the introduction of fuel in an internal combustion engine, most commonly automotive engines, by the means of a fuel injector. This article focuses on fuel injection in reciprocating piston and Wankel rotary engines. All compression-ignition engines (e.g. diesel engines), and many spark-ignition engines (i.e. petrol (gasoline) engines, such as Otto or Wankel), use fuel injection of one kind or another. Mass-produced diesel engines for passenger cars (such as the Mercedes-Benz OM 138) became available in the late 1930s and early 1940s, being the first fuel-injected engines for passenger car use. In passenger car petrol engines, fuel injection was introduced in the early 1950s and gradually gained prevalence until it had largely replaced carburetors by the early 1990s. The primary difference between carburetion and fuel injection is that fuel injection atomizes the fuel through a small nozzle under high pressure, while carburetion relies on suction created b ...
