Hybrid cars history of hybrid vehicles
Wouk said that the government program that he developed about hybrids was unknown to everyone. Victor Wouk founded and sold two successful electric industrialized companies in the late s and 50s and in he was approach by Russell Feldman, one of the founders of Motorola, who recognized the pollution from the automobile as one of the biggest problem of the environment and he wanted to discover the possible solutions with regards to this problem.
But his experiment did not work much for the possible solution. Having an idea, Wouk pondered the problem throughout the 60s and ultimately reached a clever solution. He combined the low-emission benefits of an electric car with the power of a gasoline engine to produce a hybrid vehicle. But Wouk did not get any response to his ideas for creating a hybrid car; in fact he was heavily criticized for not believing in a full-electric system. With the help of his colleague, Charlie Rosen, who shared his belief about hybrid cars, gave him the chance to prove his ideas of creating the hybrid car as one of the solution to the rapid health cost of auto-pollution.
And now the impressive capabilities of the invention of Wouk, the hybrid cars, can now be a very great help in terms of less fuel consumption and less air pollution.
Wouk and Rosen put up a new company particularly to developed their hybrid car idea and make it possible to be in the market and be used as an everyday car that belched far less harmful vapors than contemporary vehicles. Ever since the Toyota Prius was released in the market, it has been able to remain as the premier choice of hybrid cars available.
It is true that old hybrid cars looks more like an alien car and cost far more than the conventional car. However, because of the latest technology installed in newer versions of hybrid cars, it looks more like a conventional car and is far cheaper than its predecessors. It is a fact that hybrid cars today looks very much like conventional cars. However, it will enable you to cut fuel consumption in half. For example, the Honda Civic Hybrid car looks very much like its conventional version. However, when you look at it closely, the hybrid version of the Civic is able to conserve fuel much better than its gasoline counterpart.
The History of the Electric Car
The Civic Hybrid can get you 50 miles in just one gallon of gasoline. Because of the growing demand for hybrid cars, other car manufacturers are now following the footsteps of the other companies who already released a version of their hybrid car in the market.
For example, Nissan is now planning to develop and introduce a hybrid version of the Nissan Altima. Nowadays, over , hybrid cars are running on American roads wherein 95 percent of them are Japanese made. Sales were led by the conventional Prius followed by the Toyota Aqua. The Toyota Aqua , released in December , ranked as the second top-selling new car in Japan in after the conventional Prius. At the end of the hybrid take rate had fallen to 2. Since their inception in , a total of 4,, hybrid electric automobiles and sport utility vehicles have been sold in the country through May Accounting for all countries in the continent, Norway is the segment leader, with a market share of 6.
Cumulative sales of Toyota hybrids since reached 69, units in , while Honda hybrid sales reached over 8, units. Toyota sales were led by Prius with 41, units. Toyota's European hybrid sales reached 70, vehicles in , including sales of 15, Toyota Auris Hybrids. The Auris hybrid sold 32, units in During the first nine months of , over , hybrids were sold in Western Europe representing a 1.
Sales increased Seven of the top ten hybrids models sold in were from either Toyota or the Lexus brand. Cumulative TMC sales since the Prius introduction in Europe in passed the one million unit milestone in November Since hybrid car registrations in the UK totaled , units up to April , including 11, diesel-electric hybrids, which were introduced in Since , when the Prius was launched in the UK, , Toyota hybrids had been sold by May , and almost 50, Lexus models since the introduction of the RX h in A total of 37, hybrids were registered in , and while petrol-electric hybrids increased The hybrid segment market shared reached 1.
A total of , hybrid cars have been registered in France between and ,        including 33, diesel-powered hybrids. French registrations account plug-in hybrid together with conventional hybrids. The diesel-powered Peugeot HYbrid4 , launched in late , sold units. Of these, 9, were diesel-electric hybrids, down Most of the registered hybrid cars belonged to corporate fleets due to tax incentives established in the country in As a result of the tax incentives, the country has had for several years the highest hybrid market share among EU Member States.
Hybrid sales climbed from 0. Due to the financial crisis of —08 , the market fell for two years to 2. The sales decline is due to a change in the national vehicle taxation scheme.
Combined sales of Toyota and Lexus models represented The varieties of hybrid electric designs can be differentiated by the structure of the hybrid vehicle drivetrain , the fuel type, and the mode of operation. In , several automobile manufacturers announced that future vehicles will use aspects of hybrid electric technology to reduce fuel consumption without the use of the hybrid drivetrain. Regenerative braking can be used to recapture energy and stored to power electrical accessories, such as air conditioning.
Shutting down the engine at idle can also be used to reduce fuel consumption and reduce emissions without the addition of a hybrid drivetrain. In both cases, some of the advantages of hybrid electric technology are gained while additional cost and weight may be limited to the addition of larger batteries and starter motors.
There is no standard terminology for such vehicles, although they may be termed mild hybrids. Free-piston engines could be used to generate electricity as efficiently as, and less expensively than, fuel cells. Gasoline engines are used in most hybrid electric designs and will likely remain dominant for the foreseeable future. Manufacturers may move to flexible fuel engines , which would increase allowable ratios, but no plans are in place at present. Diesel-electric HEVs use a diesel engine for power generation.
Diesels have advantages when delivering constant power for long periods of time, suffering less wear while operating at higher efficiency. Diesel-electric hybrid drivetrains have begun to appear in commercial vehicles particularly buses ; as of [update] , no light duty diesel-electric hybrid passenger cars are available, although prototypes exist.
How do hybrid cars work?
Peugeot is expected to produce a diesel-electric hybrid version of its in late for the European market. There have been no concrete dates suggested for these vehicles, but press statements have suggested production vehicles would not appear before Robert Bosch GmbH is supplying hybrid diesel-electric technology to diverse automakers and models, including the Peugeot So far, production diesel-electric engines have mostly [ vague ] appeared in mass transit buses. FedEx , along with Eaton Corp.
Hydrogen can be used in cars in two ways: a source of combustible heat, or a source of electrons for an electric motor. The burning of hydrogen is not being developed in practical terms; it is the hydrogen fuel-cell electric vehicle HFEV which is garnering all the attention. Hydrogen fuel cells create electricity fed into an electric motor to drives the wheels.

Hydrogen is not burned, but it is consumed. This means molecular hydrogen, H 2 , is combined with oxygen to form water. The molecular hydrogen and oxygen's mutual affinity drives the fuel cell to separate the electrons from the hydrogen, to use them to power the electric motor, and to return them to the ionized water molecules that were formed when the electron-depleted hydrogen combined with the oxygen in the fuel cell. Recalling that a hydrogen atom is nothing more than a proton and an electron; in essence, the motor is driven by the proton's atomic attraction to the oxygen nucleus, and the electron's attraction to the ionized water molecule.
An HFEV is an all-electric car featuring an open-source battery in the form of a hydrogen tank and the atmosphere. HFEVs may also comprise closed-cell batteries for the purpose of power storage from regenerative braking, but this does not change the source of the motivation. It implies the HFEV is an electric car with two types of batteries. Since HFEVs are purely electric, and do not contain any type of heat engine, they are not hybrids.
Hybrid vehicles might use an internal combustion engine running on biofuels , such as a flexible-fuel engine running on ethanol or engines running on biodiesel. The Chevrolet Volt plug-in hybrid electric vehicle would be the first commercially available flex-fuel plug-in hybrid capable of adapting the propulsion to the biofuels used in several world markets such as the ethanol blend E85 in the U.
In split path vehicles Toyota, Ford, GM, Chrysler there are two electrical machines, one of which functions as a motor primarily, and the other functions as a generator primarily. One of the primary requirements of these machines is that they are very efficient, as the electrical portion of the energy must be converted from the engine to the generator, through two inverters , through the motor again and then to the wheels.
Specifically, they are of a type called an interior permanent magnet IPM machine or motor. These machines are wound similarly to the induction motors found in a typical home, but for high efficiency use very strong rare-earth magnets in the rotor. These magnets contain neodymium , iron and boron, and are therefore called Neodymium magnets. This resulted in 'demand destruction' as many producers quickly turned to substituting induction motors in their cars to defend their production line.
This was in spite of such motors inferior 'power to weight' ratio attributes significantly impacting all but the most powerful energy guzzling motor sizes, e. Cutting edge U. As security of supply returns, it is certain that there will accordingly be a return to superior motor designs that NdFeB Permanent Magnets enable.
In some cases, manufacturers are producing HEVs that use the added energy provided by the hybrid systems to give vehicles a power boost, rather than significantly improved fuel efficiency compared to their traditional counterparts. In the future, manufacturers may provide HEV owners with the ability to partially control this balance fuel efficiency vs. One can buy a stock hybrid or convert a stock petroleum car to a hybrid electric vehicle using an aftermarket hybrid kit.
Electric hybrids reduce petroleum consumption under certain circumstances, compared to otherwise similar conventional vehicles, primarily by using three mechanisms: . Any combination of these three primary hybrid advantages may be used in different vehicles to realize different fuel usage, power, emissions, weight and cost profiles.forum2.quizizz.com/elevar-la-autoestima-en-6-pasos.php
History of Hybrid Cars
The ICE in an HEV can be smaller, lighter, and more efficient than the one in a conventional vehicle, because the combustion engine can be sized for slightly above average power demand rather than peak power demand. The drive system in a vehicle is required to operate over a range of speed and power, but an ICE 's highest efficiency is in a narrow range of operation, making conventional vehicles inefficient. The power curve of electric motors is better suited to variable speeds and can provide substantially greater torque at low speeds compared with internal-combustion engines.
The greater fuel economy of HEVs has implication for reduced petroleum consumption and vehicle air pollution emissions worldwide . Many hybrids use the Atkinson cycle , which gives greater efficiency, but less power for the size of engine.

Reduced noise emissions resulting from substantial use of the electric motor at idling and low speeds, leading to roadway noise reduction ,  in comparison to conventional gasoline or diesel powered engine vehicles, resulting in beneficial noise health effects although road noise from tires and wind, the loudest noises at highway speeds from the interior of most vehicles, are not affected by the hybrid design alone. Reduced noise may not be beneficial for all road users, as blind people or the visually impaired consider the noise of combustion engines a helpful aid while crossing streets and feel quiet hybrids could pose an unexpected hazard.
A study conducted by the NHTSA found that crashes involving pedestrian and bicyclist have higher incidence rates for hybrids than internal combustion engine vehicles in certain vehicle maneuvers. These accidents commonly occurred on in zones with low speed limits, during daytime and in clear weather. In January the Japanese Ministry of Land, Infrastructure, Transport and Tourism issued guidelines for hybrid and other near-silent vehicles.
Congress in December ,    and the bill was signed into law by President Barack Obama on January 4, It would require hybrids and electric vehicles traveling at less than As of mid, and in advance of upcoming legislation, some carmakers announced their decision to address this safety issue shared by regular hybrids and all types of plug-in electric vehicles , and as a result, the Nissan Leaf and Chevrolet Volt , both launched in late , and the Nissan Fuga hybrid and the Fisker Karma plug-in hybrid , both launched in , include synthesized sounds to alert pedestrians, the blind and others to their presence.
