Parallel Hybrid
Hybrid vehicle drivetrains transmit power to the driving wheels for hybrid vehicles. A hybrid vehicle has multiple forms of motive power. Hybrids 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. Electrical vehicles have a long history combining internal combustion and electrical transmission as in a diesel–electric power-train although they have mostly been used for rail locomotives. A diesel–electric powertrain fails the definition of hybrid because the electric drive transmission directly replaces the mechanical transmission rather than being a supplementary source of motive power. One of the earliest forms of hybrid land vehicle was the 'trackless' trolleybus experiment in The United States (New Jersey) that ran from 1935 to 1948, which normally used traction current delivered by wire. The trolleybus was fitted with an internal combustion engine (ICE) to power the me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hybrid Vehicle
A hybrid vehicle is one that uses two or more distinct types of power, such as submarines that use diesel when surfaced and batteries when submerged. Other means to store energy include pressurized fluid in hydraulic hybrids. The basic principle with hybrid vehicles is that the different motors work better at different speeds; the electric motor is more efficient at producing torque, or turning power, and the combustion engine is better for maintaining high speed than a typical electric motor. Switching from one to the other at the proper time while speeding up yields a win-win in terms of energy efficiency, such that it translates into greater fuel efficiency. Vehicle types Two-wheeled and cycle-type vehicles Mopeds, electric bicycles, and even electric kick scooters are a simple form of a hybrid, powered by an internal combustion engine or electric motor and the rider's muscles. Early prototype motorcycles in the late 19th century used the same principle. * In a parall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torques
In physics and mechanics, torque is the rotational equivalent of linear force. It is also referred to as the moment of force (also abbreviated to moment). It represents the capability of a force to produce change in the rotational motion of the body. The concept originated with the studies by Archimedes of the usage of levers, which is reflected in his famous quote: "''Give me a lever and a place to stand and I will move the Earth''". Just as a linear force is a push or a pull, a torque can be thought of as a twist to an object around a specific axis. Torque is defined as the product of the magnitude of the perpendicular component of the force and the distance of the line of action of a force from the point around which it is being determined. The law of conservation of energy can also be used to understand torque. The symbol for torque is typically \boldsymbol\tau, the lowercase Greek letter ''tau''. When being referred to as moment of force, it is commonly denoted by . In th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saturn Vue
The Saturn Vue is a compact SUV that was sold and built by Saturn, and it was Saturn's best-selling model. It was the first vehicle to use the GM Theta platform when it was introduced in 2001 for the 2002 model year. The Vue was later facelifted for the 2006 model year. A second generation model was launched in 2007 for the 2008 model year as a rebadged Opel Antara. The Vue production in North America ended as GM wound down the Saturn brand during its 2009 reorganization. __TOC__ First generation (2002) The Vue was introduced for the 2002 model year and was designed by Saturn. It was manufactured at the Spring Hill GM plant. Its unibody platform is shared with the Chevrolet Equinox, Pontiac Torrent and the European Opel Antara. The first generation ran from model year 2002–2007. The Vue was offered in either 4 or V6 trim levels, with either a four-cylinder (I4) or V6 gasoline engine, and either a manual or automatic transmission. A sportier Red Line trim was added starti ...

Parallel Hybrid Truck
The Chevrolet Silverado is a range of trucks manufactured by General Motors under the Chevrolet brand. Introduced for the 1999 model year, the Silverado is the successor to the long running Chevrolet C/K model line. Taking its name from the top trim level from the Chevrolet C/K series, the Silverado is offered as a series of full-size pickup trucks, chassis cab trucks, and medium-duty trucks. The fourth generation of the model line was introduced for the 2019 model year. The Chevrolet Silverado shares mechanical commonality with the GMC Sierra; GMC ended the use of the C/K nomenclature a model generation prior to Chevrolet. In Mexico, high trim level versions of the Silverado use the Chevrolet Cheyenne name. Competing against the Ford F-Series, Ram Pickup, Nissan Titan, and Toyota Tundra, the Silverado is among the best-selling vehicles in the United States, having sold over 12 million examples since its introduction in 1999. History The Silverado nameplate made its de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Union Of Concerned Scientists
The Union of Concerned Scientists (UCS) is a nonprofit science advocacy organization based in the United States. The UCS membership includes many private citizens in addition to professional scientists. Anne Kapuscinski, Professor of Environmental Studies and Director of The Coastal Science and Policy Program at the University of California—Santa Cruz, currently chairs the UCS Board of Directors, having replaced James J. McCarthy, Professor of Biological Oceanography at Harvard University and past president of the American Association for the Advancement of Science in 2015. History The Union of Concerned Scientists was founded in 1969 by faculty and students of the Massachusetts Institute of Technology. The organization's founding document says it was formed to "initiate a critical and continuing examination of governmental policy in areas where science and technology are of actual or potential significance" and to "devise means for turning research applications away from the p ...

Integrated Motor Assist
Integrated Motor Assist (commonly abbreviated as IMA) is Honda's hybrid car technology, introduced in 1999 on the Insight. It is a specific implementation of a parallel hybrid. It uses an electric motor mounted between the internal combustion engine and transmission to act as a starter motor, engine balancer, and assist traction motor. Overview In its first generation, IMA could not power the car on electricity alone, and could only use the motor to assist or start the engine. 2006 Civic Hybrid, however, can activate the electric motor while the vehicle is coasting without turning on the internal combustion engine, though in contrast to Toyota's Hybrid Synergy Drive (HSD) or General Motors and DaimlerChrysler's Global Hybrid Cooperation, the IMA has a less powerful motor/generator which allows the car to slow or stop its rate of deceleration to a lesser extent; it cannot operate without turning over the engine which is directly coupled to its electric motor.

Honda Accord Hybrid
The , also known as the in Japan and China for certain generations, is a series of cars manufactured by Honda is a Japanese public multinational conglomerate manufacturer of automobiles, motorcycles, and power equipment, headquartered in Minato, Tokyo, Japan. Honda has been the world's largest motorcycle manufacturer since 1959, reaching a product ... since 1976, best known for its four-door Sedan (automobile), sedan variant, which has been one of the best-selling cars in the United States since 1989. The Accord nameplate has been applied to a variety of vehicles worldwide, including coupes, station wagons, hatchbacks and a Honda Crosstour crossover. Since its initiation, Honda has offered several different car body styles and versions of the Accord, and often vehicles marketed under the Accord nameplate concurrently in different regions differ quite substantially. It debuted in 1976, as a compact car, compact hatchback, though this style only lasted through 1989, as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
