Comparison Of Toyota Hybrids
By the end of 2006 there were about 15 hybrid vehicles from various car makers available in the U.S.Pernick, R. and Wilder, C. (2007). The Clean Tech Revolution, p. 4. By May 2007 Toyota sold its first million hybrids and had sold a total of two million hybrids at the end of August 2009. Comparisons Below is a comparison of the Toyota hybrid models. * Note: Miles per gallon estimates are those provided by the United States Environmental Protection Agency (EPA) and are the 2008 revision of the original numbers. * Hybrid access to US HOV lanes varies by US state. Factors can include total/average miles per gallon rating from the EPA, type of technology used, and/or date of vehicle registration with the relevant state authorities. (Several states have begun restricting HOV lane access by hybrid and clean-fuel vehicles due to crowding.) * Traction battery power is the amount of power available from the electric portion of the powertrain without the aid of the internal combustion e ...

The Clean Tech Revolution
''The Clean Tech Revolution: The Next Big Growth and Investment Opportunity'' is a 2007 book by Ron Pernick and Clint Wilder, who say that commercializing clean technologies is a profitable enterprise that is moving steadily into mainstream business. As the world economy faces challenges from energy price spikes, resource shortages, global environmental problems, and security threats, clean technologies are seen to be the next engine of economic growth. Pernick and Wilder highlight eight major clean technology sectors: solar power, wind power, biofuels, green buildings, personal transportation, the smart grid, mobile applications, and water filtration.Anderson, Leonard (August 5, 2007)For investors, a heads-up on clean tech ''The Boston Globe''. Retrieved 15 December 2010. Six major forces, which they call the six C's, are pushing clean technology into the mainstream: costs, capital, competition, China, consumers, and climate. Very large corporations such as GE, Toyota ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atkinson Cycle
The Atkinson-cycle engine is a type of internal combustion engine invented by James Atkinson in 1882. The Atkinson cycle is designed to provide efficiency at the expense of power density. A variation of this approach is used in some modern automobile engines. While originally seen exclusively in hybrid electric applications such as the earlier-generation Toyota Prius, later hybrids and some non-hybrid vehicles now feature engines with variable valve timing, which can run in the Atkinson cycle as a part-time operating regimen, giving good economy while running in Atkinson cycle, and conventional power density when running as a conventional, Otto cycle engine. Design Atkinson produced three different designs that had a short compression stroke and a longer expansion stroke. The first Atkinson-cycle engine, the ''differential engine'', used opposed pistons. The second and best-known design was the ''cycle engine'', which used an over-center arm to create four piston strokes in one ...

Traction Battery
An electric vehicle battery (EVB, also known as a traction battery) is a rechargeable battery used to power the electric motors of a battery electric vehicle (BEV) or hybrid electric vehicle (HEV). Typically lithium-ion batteries, they are specifically designed for high electric charge (or energy) capacity. Electric vehicle batteries differ from starting, lighting, and ignition (SLI) batteries as they are designed to give power over sustained periods of time and are deep-cycle batteries. Batteries for electric vehicles are characterized by their relatively high power-to-weight ratio, specific energy and energy density; smaller, lighter batteries are desirable because they reduce the weight of the vehicle and therefore improve its performance. Compared to liquid fuels, most current battery technologies have much lower specific energy, and this often impacts the maximum all-electric range of the vehicles. The most common battery type in modern electric vehicles are lithium-ion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internal Combustion Engine
An internal combustion engine (ICE or IC engine) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine. The force is typically applied to pistons ( piston engine), turbine blades (gas turbine), a rotor (Wankel engine), or a nozzle ( jet engine). This force moves the component over a distance, transforming chemical energy into kinetic energy which is used to propel, move or power whatever the engine is attached to. This replaced the external combustion engine for applications where the weight or size of an engine was more important. The first commercially successful internal combustion engine was created by Étienne Lenoir around 1860, and the first modern internal combustion engine, known ...

Powertrain
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] |
Miles Per Gallon
The fuel economy of an Car, automobile relates distance traveled by a vehicle and the amount of fuel consumption, fuel consumed. Consumption can be expressed in terms of volume of fuel to travel a distance, or the distance traveled per unit volume of fuel consumed. Since fuel consumption of vehicles is a significant factor in air pollution, and since importation of motor fuel can be a large part of a nation's foreign trade, many countries impose requirements for fuel economy. Different methods are used to approximate the actual performance of the vehicle. The energy in fuel is required to overcome various losses (wind resistance, tire drag, and others) encountered while propelling the vehicle, and in providing power to vehicle systems such as ignition or air conditioning. Various strategies can be employed to reduce losses at each of the conversions between the chemical energy in the fuel and the kinetic energy of the vehicle. Driver behavior can affect fuel economy; maneuvers suc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SULEV
Super ultra-low emissions vehicle (SULEV) is a U.S. classification for passenger vehicle emissions. The classification is based on producing 90% fewer emissions than the average gasoline-powered vehicle. The SULEV standard is stricter than the standard for LEV (low emission vehicle) and ULEV (ultra-low-emission vehicle), however not as strict as PZEV (partial zero-emissions vehicle) which meets the SULEV standard for tailpipe emissions, but has zero instead of reduced evaporative emissions. Japan also offers an SU-LEV classification, for vehicles that show a 75 percent reduction in emissions vis-à-vis the 2005 emissions standards. Examples Examples of vehicles delivering SULEV emissions performance include: *Honda Accord 2000-? *Honda Insight (CVT transmission models only) *Honda Civic Hybrid CVT transmission models only, AT-PZEV available in certain states * Honda Civic GX Natural Gas * Honda CR-Z (AT-PZEV) *Toyota Prius *Ford Focus SULEV * BMW SULEV 128i, 328i, 325i, 325Ci, ...

AT-PZEV
A partial zero-emission vehicle, in the United States, is an automobile that has zero evaporative emissions from its fuel system, has a 15-year (or at least 150,000-mile) warranty on its emission-control components, and meets SULEV tailpipe-emission standards. Definition and history In California, PZEVs have their own administrative category for low-emission vehicles. The category was made in a bargain between automakers and the California Air Resources Board (CARB), so that automobile makers could delay making mandated zero-emission vehicles (ZEVs)—battery electric and fuel-cell electric vehicles. The super-ultra-low-emission vehicle (SULEV) standard is more stringent than the ultra-low-emission vehicle (ULEV) and low-emission vehicle standards. All emissions-related components, including the electric-propulsion parts of hybrid electric vehicles, must be warranted for 15 years or 150,000 miles. Advanced Technology PZEVs (AT-PZEVs) are at least as "clean" as regular PZEVs. C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
California Air Resources Board
The California Air Resources Board (CARB or ARB) is the "clean air agency" of the government of California. Established in 1967 when then-governor Ronald Reagan signed the Mulford-Carrell Act, combining the Bureau of Air Sanitation and the Motor Vehicle Pollution Control Board, CARB is a department within the cabinet (government), cabinet-level California Environmental Protection Agency. The stated goals of CARB include attaining and maintaining healthy air quality; protecting the public from exposure to toxic air contaminants; and providing innovative approaches for complying with air pollution rules and regulations. CARB has also been instrumental in driving innovation throughout the global automotive industry through programs such as its ZEV mandate. One of CARB's responsibilities is to define United States emission standards, vehicle emissions standards. California is the only state permitted to issue emissions standards under the federal Clean Air Act (United States), Clean ...

Octane Rating
An octane rating, or octane number, is a standard measure of a fuel's ability to withstand compression in an internal combustion engine without detonating. The higher the octane number, the more compression the fuel can withstand before detonating. Octane rating does not relate directly to the power output or the energy content of the fuel per unit mass or volume, but simply indicates gasoline's capability against compression. Whether or not a higher octane fuel improves or impairs an engine's performance depends on the design of the engine. In broad terms, fuels with a higher octane rating are used in higher-compression gasoline engines, which may yield higher power for these engines. Such higher power comes from the fuel's higher compression by the engine design, and not directly from the gasoline. In contrast, fuels with lower octane (but higher cetane numbers) are ideal for diesel engines because diesel engines (also called compression-ignition engines) do not compress the fue ...

Road & Track
''Road & Track'' (stylized as ''R&T'') is an American automotive enthusiast magazine. It is owned by Hearst Magazines and is published 6 times per year. The editorial offices are located in New York, New York. History ''Road & Track'' (often abbreviated ''R&T'') was founded by two friends, Wilfred H. Brehaut, Jr. and Joseph S. Fennessy, in 1947, in Hempstead, New York. Published only six times from 1947 to 1949, it struggled in its early years. By 1952, regular contributor and editor John R. Bond and his wife Elaine had become the owners of the magazine, which then grew until its sale to CBS Publications in 1972. The ampersand (&) in the title was introduced in 1955 by then Editor Terry Galanoy, who replaced the word "and" in the magazine's name because the words Road and Track were graphically too long for newsstand-effective recognition. In 1988, Hachette Filipacchi Media took ownership of the magazine. In October 2008, Matt DeLorenzo became editor-in-chief, succeeding Tho ...
