Hybrid cars 2 essay

Hybrid cars use both gas and electric.

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.

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.

Technology 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.

Diesel Diesel-electric HEVs use a diesel engine for power generation. A hybrid car, also known as an HEV or hybrid electric vehicle, is an automobile that is powered by two sources; an internal combustion engine, and an electric motor.

With cars with this system, a hybrid car can cross longer distances than normal ones with less use of gasoline. While petroleum-derived gasoline is the primary fuel, it is possible to mix in varying levels of ethanol created from renewable energy sources.

Regenerative braking capability, which helps minimize the energy lost when driving.

Shutting down the engine at idle can also be used to reduce fuel consumption and reduce emissions without the addition of a hybrid drivetrain. Fuel efficiency is greatly increased, while emissions are greatly decreased.

They can get up to mpg in city driving, while a typical SUV might travel just mpg. Regular HEVs most commonly use an internal combustion engine ICE in tandem with electric motors to power their propulsion system.

Fuel consumption Current HEVs reduce petroleum consumption compared to otherwise similar conventional vehicles primarily by using three mechanisms: The greater fuel economy of HEVs has implication for reduced petroleum consumption and vehicle air pollution emissions worldwide.

There are two configurations for hybrid cars. Diesel-electric hybrid drivetrains have begun to appear in commercial vehicles particularly buses ; as ofno light duty diesel-electric hybrid passenger cars are currently available, although prototypes exist. Inseveral automobile manufacturers announced that future vehicles will use aspects of hybrid electric technology to reduce fuel consumption without the use of the hybrid drivetrain.

The gasoline engine is the primary source of power, while the electric motor is used at low speeds. 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.

Also there are 2 types of cars: An additional benefit of the parallel configuration is that no outside source of electric power is required because the engine itself generates the required electricity.

Regenerative braking can be used to recapture energy and stored to power electrical accessories, such as air conditioning. Diesels have advantages when delivering constant power for long periods of time, suffering less wear while operating at higher efficiency.

Hybrid Cars

Electric vehicle conversion One can buy a stock hybrid or convert a stock petroleum car to a hybrid electric vehicle using an aftermarket hybrid kit. HEVs became widely available to the public in the late s. Engines and fuel sources: HEVs are viewed by some automakers as a core segment of the future automotive market.

Reduced wear on the gasoline engine, particularly from idling with no load. So far, production diesel-electric engines have mostly just appeared in mass transit buses.

Design considerations 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. Reduced wear on brakes from the regenerative braking system use.Hybrid cars: Corrected Abstract: A hybrid car, also known as an HEV or hybrid electric vehicle, is an automobile that is powered by two sources; an internal combustion engine, and an electric motor.

HEV’s need plugs, as they are amply charged by the movement of the wheels and storing the kinetic energy that is generated [ ]. Hybrid Cars (What is a Hybrid Car?) There are two configurations for hybrid cars.

The first configuration uses gasoline engine to run a generator. Most hybrid cars work by letting the electric part of the hybrid perform task that a gas engine does inefficiently.

When more power is needed, the gas engine kicks in to provide extra power. Some hybrids are able to run solely on the electric motor until it reaches a threshold in which the gas engine kicks in. Hybrid Cars: The Slow Drive to Energy Security The hybrid car market is slowly ramping up.

In the past five years the number of hybrid sales in the U.S. grew tenfold from 9, in toin We will write a custom essay sample on The Benefits of Hybrid Cars specifically for you for only $ $/page.

Order now The main energy that propelled vehicle was steam source. In Belgian, Henry Pieper, invents and patents a hybrid chart for a car.

But if manufacturers of hybrid cars were to see a yield in economies of scale then there would be more reason for producers of the battery to put more time and money into research and development of the battery and thus decrease costs of producing it.

this would in term pass savings onto the potential buyers of the hybrid car.
