Porsche 996
The Porsche 996 is the internal designation for the 911 model manufactured by the German automaker Porsche from 1997 until 2006. It was replaced by the 997 in 2004, but the high performance Turbo S, GT2 and GT3 variants remained in production until 2006. The 996 had little in common with its predecessor, with the first all new chassis platform since the original 911 and a new water-cooled engine. Technically, it was a major change, a complete breakthrough from the original car other than the overall layout. The 996's development was shared with the roadster-only Porsche Boxster (986) whose nameplate was making its debut as Porsche's entry-level offering. The 986 was released shortly before the 996 for sales. Commonalities between the 996 and 986 included the front suspension, various interior components, and the engine, all of which were enlarged for the 996. However, the multi-link rear suspension was derived from the preceding 993. This was done mainly to save development cos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Porsche 911
The Porsche 911 (pronounced ''Nine Eleven'' or in german: Neunelfer) is a two-door 2+2 high performance rear-engined sports car introduced in September 1964 by Porsche AG of Stuttgart, Germany. It has a rear-mounted flat-six engine and originally a torsion bar suspension. The car has been continuously enhanced through the years but the basic concept has remained unchanged.Corlett, p. 12 The engines were air-cooled until the introduction of the 996 series in 1998. The 911 has been raced extensively by private and factory teams, in a variety of classes. It is among the most successful competition cars. In the mid-1970s, the naturally aspirated 911 Carrera RSR won world championship races including Targa Florio and the 24 Hours of Daytona. The 911-derived 935 turbo also won the 24 Hours of Le Mans in 1979. Porsche won the World Championship for Makes in 1976, 1977, 1978, and 1979 with 911-derived models. In a 1999 poll to determine the Car of the Century, the 911 was fifth. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ZF 5HP19 Transmission
''This article describes automobile transmission. For heavy-duty 5 speed automatic transmission, see ZF Ecomat.'' 5HP is ZF Friedrichshafen AG's trademark name for its five-speed automatic transmission models (5-speed transmission with Hydraulic converter and Planetary gearsets) for longitudinal engine applications, designed and built by ZF's subsidiary in Saarbrücken. Specifications Final Conventionally Designed Gearbox The 5HP is the last transmission family that utilized a conventional design. To meet the requirements for a greater number of gear ratios, the only viable option entailed adding more components. That made these gearboxes bigger, heavier and even more expensive to build. As the presence of up to ten main components (two Ravigneaux gearsets in series, along with brakes and clutches) showed, this marked the end of conventional gearbox design. The successor, the 6HP-family, employed an all-new Lepelletier gear mechanism design, which needed only eight main com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toyota
is a Japanese multinational automotive manufacturer headquartered in Toyota City, Aichi, Japan. It was founded by Kiichiro Toyoda and incorporated on . Toyota is one of the largest automobile manufacturers in the world, producing about 10 million vehicles per year. The company was originally founded as a spinoff of Toyota Industries, a machine maker started by Sakichi Toyoda, Kiichiro's father. Both companies are now part of the Toyota Group, one of the largest conglomerates in the world. While still a department of Toyota Industries, the company developed its first product, the Type A engine in 1934 and its first passenger car in 1936, the Toyota AA. After World War II, Toyota benefited from Japan's alliance with the United States to learn from American automakers and other companies, which would give rise to The Toyota Way (a management philosophy) and the Toyota Production System (a lean manufacturing practice) that would transform the small company into a leader in t ...

Valve
A valve is a device or natural object that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways. Valves are technically fittings, but are usually discussed as a separate category. In an open valve, fluid flows in a direction from higher pressure to lower pressure. The word is derived from the Latin ''valva'', the moving part of a door, in turn from ''volvere'', to turn, roll. The simplest, and very ancient, valve is simply a freely hinged flap which swings down to obstruct fluid (gas or liquid) flow in one direction, but is pushed up by the flow itself when the flow is moving in the opposite direction. This is called a check valve, as it prevents or "checks" the flow in one direction. Modern control valves may regulate pressure or flow downstream and operate on sophisticated automation systems. Valves have many uses, including controlling water for irrigation, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air-cooled
Air-cooled engines rely on the circulation of air directly over heat dissipation fins or hot areas of the engine to cool them in order to keep the engine within operating temperatures. In all combustion engines, a great percentage of the heat generated (around 44%) escapes through the exhaust, not through the metal fins of an air-cooled engine (12%). About 8% of the heat energy is transferred to the oil, which although primarily meant for lubrication, also plays a role in heat dissipation via a cooler. ''Air-cooled engines'' are used generally in applications which would not suit liquid cooling, as such modern air-cooled engines are used in motorcycles, general aviation aircraft, lawn mowers, generators, outboard motors, pump sets, saw benches and auxiliary power units. Introduction Most modern internal combustion engines are cooled by a closed circuit carrying liquid coolant through channels in the engine block and cylinder head, where the coolant absorbs heat, to a heat ...

Water-cooled
Cooling tower and water discharge of a nuclear power plant Water cooling is a method of heat removal from components and industrial equipment. Evaporative cooling using water is often more efficient than air cooling. Water is inexpensive and non-toxic; however, it can contain impurities and cause corrosion. Water cooling is commonly used for cooling automobile internal combustion engines and power stations. Water coolers utilising convective heat transfer are used inside high-end personal computers to lower the temperature of CPUs. Other uses include the cooling of lubricant oil in pumps; for cooling purposes in heat exchangers; for cooling buildings in HVAC and in chillers. Mechanism Advantages Water is inexpensive, non-toxic, and available over most of the earth's surface. Liquid cooling offers higher thermal conductivity than air cooling. Water has unusually high specific heat capacity among commonly available liquids at room temperature and atmospheric pressure allowing ...

Multi-link Suspension
A multi-link suspension is a type of vehicle suspension with one or more longitudinal arms. A wider definition can consider any independent suspensions having three control links or more multi-link suspensions. These arms do not have to be of equal length, and may be angled away from their "obvious" direction. It was first introduced in the late 1960s on the Mercedes-Benz C111 and later on their W201 and W124 series. Typically each arm has a spherical joint (ball joint) or rubber bushing at each end. Consequently, they react to loads along their own length, in tension and compression, but not in bending. Some multi-links do use a trailing arm, control arm or wishbone, which has two bushings at one end. On a front suspension one of the lateral arms is replaced by the tie-rod, which connects the rack or steering box to the wheel hub. The solid axle multi-link system is another variation of the same concept, and offers some advantages over independent multi-link, as it is sign ...

Harm Lagaay
Harm Lagaay (born Harm Lagaaij, 28 December 1946, The Hague) is a Dutch automobile designer. Educated in the Netherlands he completed the studies at the IVA and went to work for a Dutch company Olyslager in Soest, Netherlands, Soest. In the late 1960s, Lagaay went to work for Simca, then from 1971 for Porsche. He worked in the team designing the Porsche 911 and designed the Porsche 924. From 1977, Lagaay worked as Chief of Design for Ford Motor Company, Ford in Cologne, and moved to BMW in 1985. Lagaay designed the BMW Z1 sports car, with electric doors hiding under the car's chassis and easily exchangeable body panels. This car was too advanced for its times and did not have commercial success, as only 8000 were sold. Today, the BMW Z1 is a collector's item. He returned to Porsche in 1989 as head of the "Style Porsche" department in Weissach.http://newsroom.porsche.com/en/products/one-icon-four-designers-10714.html''One icon, four designers'' As well as the Porsches of the pe ...

Porsche 997
Porsche 997 is the internal designation for the Porsche 911 sports car manufactured and sold by the German automobile manufacturer Porsche between 2004 (as Model Year 2005) and 2013. Production of the Carrera and Carrera S coupés began in early 2004, all-wheel drive Carrera 4 and Carrera 4S began to be delivered to customers in November 2005, the Turbo and GT3 derivatives went on sale in late 2006 and the GT2 in 2007. In addition to the coupé and cabriolet versions, Targa versions of the Carrera 4 and Carrera 4S were also available, which carry on with the "glass canopy" roof design used since its first application on the 993 until the 991, which reverted to the classic targa top layout used on the early 911 Targas. The 997 was an evolution of the preceding 996, with the most significant changes being interior and exterior styling, the most notable being the replacement of the "fried egg" headlamps used on the 996 with the classic "bug eye" units. Larger 18-inch wheels were fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Porsche 993
The Porsche 993 is the internal designation for the Porsche 911 model manufactured and sold between January 1994 and early 1998 (model years 1995–1998 in the United States), replacing the 964. Its discontinuation marked the end of air-cooled 911 models. The 993 was much improved over and quite different from its predecessor. According to Porsche, every part of the car was designed from the ground up, including the engineAutoTraderClassics.com — Article Finding Porsche's best road car — Porsche 911S vs 993. and only 20% of its parts were carried over from the previous generation. Porsche refers to the 993 as "a significant advance, not just from a technical, but also a visual perspective." Porsche's engineers devised a new light-alloy subframe with coil and wishbone suspension (an all new multi-link system, Weissach axle), putting behind the previous lift-off oversteer and making significant progress with the engine and handling, creating a more civilized ca ...

Manual Transmission
A manual transmission (MT), also known as manual gearbox, standard transmission (in Canada, the United Kingdom, and the United States), or stick shift (in the United States), is a multi-speed motor vehicle transmission (mechanics), transmission system, where gear changes require the driver to manually select the gears by operating a gear stick and clutch (which is usually a foot pedal for cars or a hand lever for motorcycles). Early automobiles used ''sliding-mesh'' manual transmissions with up to three forward gear ratios. Since the 1950s, ''constant-mesh'' manual transmissions have become increasingly commonplace and the number of forward ratios has increased to 5-speed and 6-speed manual transmissions for current vehicles. The alternative to a manual transmission is an automatic transmission; common types of automatic transmissions are the Automatic transmission#Hydraulic automatic transmissions, hydraulic automatic transmission (AT), and the continuously variable transmissio ...
