Car Longevity
Car longevity is of interest to many car owners and includes several things: maximum service life in either mileage or time (duration), relationship of components to this lifespan, identification of factors that might afford control in extending the lifespan. Barring an accidental end to the lifespan, a car would have a life constrained by the earliest part to fail. Some have argued that rust and other factors related to the body of a car are the prime limits to extended longevity. Background An automobile is a highly engineered collection of complex components, each of which has its own lifespan and longevity characteristics. The MTBF (mean time between failures) of some components is expected to be smaller than the life of the car, as the replacement of these is considered part of regular maintenance. Other components, which typically experience less wear, are expected to have a longer life; however, a large longevity may very well require replacement of several of these, raising ...

Service Life
A product's service life is its period of use in service. Several related terms describe more precisely a product's life, from the point of manufacture, storage, and distribution, and eventual use. Service life has been defined as "a product life, product's total life in use from the point of sale to the point of discard" and distinguished from replacement life, "the period after which the initial purchaser returns to the shop for a replacement". Determining a product's expected service life as part of business policy (product life cycle management) involves using tools and calculations from maintainability and Reliability engineering, reliability analysis. Service life represents a commitment made by the item's manufacturer and is usually specified as a median. It is the time that any manufactured item can be expected to be "serviceable" or Product support, supported by its Original equipment manufacturer, manufacturer. Service life is not to be confused with ''shelf life'', wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saab 900
The Saab 900 is a mid-sized automobile which was produced by Saab from 1978 until 1998 in two generations; the first from 1978 to 1993, and the second from 1994 to 1998. The first-generation car was based on the Saab 99 chassis, though with a longer front end . The 900 was produced in 2- and 4-door sedan, and 3- and 5-door hatchback configurations and, from 1986, as a cabriolet ( convertible) model. There were single- and twin-Zenith carburettor; fuel injected, and turbocharged engines, including both Full Pressure Turbo (FPT), and, in European models during the early 1990s, Low Pressure Turbos (LPT). Saab 900 "Classic" Overview The Saab 900 is a front-engine, front-wheel-drive mid-size car with a longitudinally mounted, 45-degree slanted, inline four-cylinder engine, double wishbone front suspension and beam-axle rear suspension.

Car Ownership
Car ownership is the ownership of a car. Car ownership typically requires far fewer permits than driving that car on public roads (i.e. driver's license, car insurance, etc.). History Levels of ownership have risen significantly since automobiles were pioneered in the 19th century. The United States was the first country in which mass ownership became common and 60% of families owned a car in 1929. By the 21st century in the United States, there was, on average, a vehicle for every person of driving age and more vehicles than people with driving licenses. This level of ownership was so great that, in 2010, the total number of vehicles dropped significantly for the first time, falling by four million to 247 million. Overall, across the world, levels of ownership increased fourfold between 1950 and 1999, from 48 people per automobile in 1950 to just 12. Forms of ownership A car is typically a major purchase and so there are a variety of financial schemes to facilitate the purchase ...

Sustainable Transport
Sustainable transport refers to ways of transportation that are sustainable in terms of their social and environmental impacts. Components for evaluating sustainability include the particular vehicles used for road, water or air transport; the source of energy; and the infrastructure used to accommodate the transport (roads, railways, airways, waterways, canals and terminals). Transport operations and logistics as well as transit-oriented development are also involved in evaluation. Transportation sustainability is largely being measured by transportation system effectiveness and efficiency as well as the environmental and climate impacts of the system. Transport systems have significant impacts on the environment, accounting for between 20% and 25% of world energy consumption and carbon dioxide emissions. The majority of the emissions, almost 97%, came from direct burning of fossil fuels. In 2019, about 95% of the fuel came from fossil sources. The main source of greenhouse ...

Scrappage Program
A scrappage program is a government budget programme to promote the replacement of old vehicles with modern vehicles. Scrappage programmes generally have the dual aim of stimulating the automobile industry and removing inefficient, more polluting vehicles from the road. Many European countries have introduced large-scale scrappage programmes as an economic stimulus to increase market demand in the industrial sector during the global recession that began in 2008. Scrappage programmes were touted with different names, mostly referring to an environmental benefit. The Vehicle Efficiency Incentive in Canada was based on fuel efficiency of cars. In Romania, this program was called "Rabla" (the wreck), and was launched by Dacia in 2000. In Germany, the economic stimulus program was called "Umweltprämie" (''environmental premium'') and in Austria "Ökoprämie" (''eco-premium'') while most of the public referred to it simply as "Abwrackprämie" (''scrappage premium''). Other countries ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reliability Engineering
Reliability engineering is a sub-discipline of systems engineering that emphasizes the ability of equipment to function without failure. Reliability describes the ability of a system or component to function under stated conditions for a specified period of time. Reliability is closely related to availability, which is typically described as the ability of a component or system to function at a specified moment or interval of time. The reliability function is theoretically defined as the probability of success at time t, which is denoted R(t). This probability is estimated from detailed (physics of failure) analysis, previous data sets or through reliability testing and reliability modelling. Availability, testability, maintainability and maintenance are often defined as a part of "reliability engineering" in reliability programs. Reliability often plays the key role in the cost-effectiveness of systems. Reliability engineering deals with the prediction, prevention and mana ...

Volkswagen Beetle
The Volkswagen Beetle—officially the Volkswagen Type 1, informally in German (meaning "beetle"), in parts of the English-speaking world the Bug, and known by many other nicknames in other languages—is a two-door, rear-engine economy car, intended for five occupants (later, Beetles were restricted to four people in some countries), that was manufactured and marketed by German automaker Volkswagen (VW) from 1938 until 2003. The need for a ''people's car'' ( in German), its concept and its functional objectives were formulated by the leader of Nazi Germany, Adolf Hitler, who wanted a cheap, simple car to be mass-produced for his country's new road network (Reichsautobahn). Members of the National Socialist party, with an additional dues surcharge, were promised the first production, but the Spanish Civil War shifted most production resources to military vehicles to support the Nationalists under Francisco Franco. Lead engineer Ferdinand Porsche and his team took until 193 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mercedes-Benz Museum
The Mercedes-Benz Museum is an automobile museum in Stuttgart, Germany. It covers the history of the Mercedes-Benz brand and the brands associated with it. Stuttgart is home to the Mercedes-Benz brand and the international headquarters of the Mercedes-Benz Group. The museum building The current building, which stands directly outside the main gate of the Daimler factory in Stuttgart, was designed by UN Studio. It is based on a unique cloverleaf concept using three overlapping circles with the center removed to form a triangular atrium recalling the shape of a Wankel engine. The building was completed and opened on 19 May 2006. Architecture and exhibition concept are closely interwoven, as exhibition designer HG Merz had already been commissioned before the architecture competition in 2001. The building's height and "double helix" interior were designed to maximise space, providing of exhibition space on a footprint of just . The double helix also corresponds to the exhibiti ...

MTBF
Mean time between failures (MTBF) is the predicted elapsed time between inherent failures of a mechanical or electronic system during normal system operation. MTBF can be calculated as the arithmetic mean (average) time between failures of a system. The term is used for repairable systems while mean time to failure (MTTF) denotes the expected time to failure for a non-repairable system. The definition of MTBF depends on the definition of what is considered a failure. For complex, repairable systems, failures are considered to be those out of design conditions which place the system out of service and into a state for repair. Failures which occur that can be left or maintained in an unrepaired condition, and do not place the system out of service, are not considered failures under this definition. In addition, units that are taken down for routine scheduled maintenance or inventory control are not considered within the definition of failure. The higher the MTBF, the longer a syste ...
