Petroleum Consumption Figure 4. Potential reduction in CS-mode petroleum consumption [9] The results include petroleum consumption data from a range of PHEVs and HEVs. The graph shows apparent differences between each of the models. The curve at the bottom represents hybrid vehicles that cannot run on electric only mode. Six models are selected from four degrees of hybridization which are micro, mild, medium, and full. Staring from 0% at the bottom left, the curve goes up as the degree of hybridization goes up. The Vue, one micro hybrid car model, can reduce the petroleum usage by 18%, while the Toyota Prius, one of the best full hybrid models in the world, can reduce the petroleum usage over 40%. Even though the Toyota Prius can …show more content…
Even micro HEVs, the hybrid vehicle model with the lowest degree of hybridization, can reduce the petroleum usage over 20%. It is important to know the amount of petroleum consumption of HEVs because a daily 20% reduction can add up. The following figure.5 clearly presents the annual reduction in petroleum. Figure 5. Reduction in Annual Petroleum Consumption (gals.) and the cost increment [9] HEV0 models are full hybrids such as the Toyota Prius. HEV0 reduces annual petroleum consumption from 120 to 200 gallons over a distance of 15,000 miles, while PHEV60 reduces that from 350 to 420 gallons. But what do these data mean? Here I present an example of a conventional vehicle. A CV uses 659 gallons of petroleum each year based on a travel distance of 15,000 miles. HEV0 saves 20%~28% of petroleum, and PHEV60 saves 53%~64% of the petroleum. [9] The reduction of petroleum consumption on PHEV60 is even more than half. It means that, in theory, PHEV60 can travel twice the distance that a CV can in a year. Nevertheless, the vertical axis of the graph tells us more. How can we deal with the cost? Economics Factor As figure 5. Shows, even though PHEVs and HEVs can save a significant amount of petroleum each year and PHEV60 even saves half of the petrol, the incremental cost on the powertrain doubles. It is true that many people would rather buy a cheaper traditional car than a way more expensive
In addition, consumer must be aware that there are better alternatives to hybrids on market. Thanks to advancing technology, many petro powered and diesel powered vehicle get similar EPA fuel economy on highway. From German automotive manufacture, they have developed Clean Diesel such as Blue Tec from Mercedes-Benz and TDI from Volkswagen which
“Globally, 753 000 plug-in EVs were sold in 2016, 60% of which were battery-electric cars (BEVs). These sales were the highest ever registered and allowed the global EV stock to hit the threshold of 2 million units in circulation”, according to the Energy International Agency. The debate on whether electric vehicles are truly more environmentally friendlier, safer, fuel efficient and overall more reliable than the average gasoline vehicle has been prevalent since the debut of electric vehicles on the streets. Driving an electric powered vehicle will have positive benefits that will eventually assist the earth and your pocket in my many ways. It is true, choosing electric vehicles over gasoline powered ones can positively change the
Hybrid vehicles are continuously gaining popularity in the general public. With the growing societal concerns about green revolution and also achieving significant reduction in fuel consumption, hybrid vehicles are considered satisfactory in performance. They have become so popular that certain tax incentives have been offered by the government on hybrid vehicles. Due to their better performance compared with gas powered vehicles, we present the thesis of our paper as follows:
On Edmunds.com.” Edmunds. Hybrid cars have been saving the world little by little, first off hybrid cars have an excellent gas mileage because they are powered by an electric motor and slight gas, which can go much more farther than gas powered vehicles(“What Are Hybrid Cars and How Do They Work?). Also it will not produce smog , which is a good thing for the economy and the environment, the other reason why they are good in gas mileage is because the are light and there aerodynamics (“Hybrid Cars--Pros and Cons.” ). Hybrid cars are changing the economy by using much less has and less oil, they are more likely to save you money on the long
If you listen to the car companies, hybrid cars are the best invention since sliced bread. While there are many reasons to buy a hybrid car, including a new tax incentive for US owners, it doesn 't hurt to have a good understanding of how they work. This article explores the myths, benefits and drawbacks of owning one of these new "green" vehicles. Are hybrid cars really more cost effective?
As the fuel engine runs the battery charges. The battery is connecting to the powerful 543kw motor, which can make it run 60 kmp/h for a long day. All hybrid cars running on batteries most of the times. So it is having a huge fuel efficiency when compared to others.
Another study published in 2011 revealed that the gasoline cost savings in PEVs did not increase the purchase of PEVs due to short run time. [11][12]
The research will show the innumerous benefits of 2 specific alternative-fueled cars: Electric Vehicle and Hydrogen-Powered Vehicles, while also comparing and contrasting their benefits to conventional vehicles. Although the environmental impact of a car is not taken into consideration while buying
This report explains how advantageous a hybrid car is and why conventional car should be replaced by hybrid car. Hybrid car is getting more popular and marketable because of its advantages. In essence, the report touches on the benefits of owning a hybrid car and some possible effects. The problems that arisen are environmental problems which catch the whole world’s attention, the prices and fuel are hiking up and the fuels are limited in supply. Therefore, hybrid cars are here to help people to overcome the problems. They are definitely the best solution to replace conventional cars because they are more advantageous than conventional cars. Hybrid cars have the ability to save fuel which ultimately reduces the dependence on
Hybrid vehicles, which are environmentally friendly vehicles, which will replace fossil fueled car in the future but they have a limited range and long fueling time. As fossil fuel resources start to become limited and non-environmentally friendly, car manufacturers are looking to find ways to make hybrid vehicles the future of transportation. Hybrid vehicles are beneficial since they are efficient, reduce pollution, and cut global emission than the current hybrids models. As such, hybrid-electric vehicles can have real public benefits for both the environment and for energy security. Hybrid vehicles can help reduce smog pollution by ninety percent or more in comparison to the cleanest conventional vehicles today. Hybrids also give a rewarding tax insensitive in a way to get more people to buy and drive hybrid vehicles to help keep the environment clean. As for now, hybrids have their strengths and weaknesses that haven 't been perfected yet, but they keep on getting better each year.
Abstract- Today’s environmental situation is continuing to spiral downwards; the ozone layer is receding, habitats being destroyed, and the air is being polluted. Scientists of every nation are researching ways to solve this problem. Due to automobiles sizeable contribution to the environmental crisis, studies are focusing on ways to reduce the harmful emissions caused by the internal combustion engines. Hybrid vehicles offer an alternative to powerful gas engines by providing the car with a secondary propulsion source powered by a strong battery. With this secondary power, car manufactures can reduce the size of the internal combustion engine, which accordingly reduces emissions and raises the vehicles miles
Automobiles have become such an integral part of living in a modern society. Many places in the first world are inexplicably fortunate enough to have such incredible transportation technology at their finger tips. While this technology is a dream, the gasoline powered cars we use today attribute to about 25% of the worlds carbon emissions (Agassi, Shai Agassi: A new ecosystem for electric cars). This is a giant concern, but the car industry may find themselves a little more concerned with the depleting oil that is burned away daily by drivers. It’s unavoidable, there needs to be a change made sooner than later, and hybrid isn’t solving our problems fast enough. The best alternate choice seems to be a full conversion to electric cars. These cars replace gasoline engines with an electric one, running on battery power. The battery of these cars runs current through the motor to the wheels, operating like a light and a light switch where the increase in speed is similar to having a dimmer on that light (Brain, How Electric Cars Work 1). This technology removes the harmful carbon emission, making it a sustainable solution to our current problems, but it still struggles to be implemented as it has since it was first created.
With the ever growing concern about greenhouse gases today and the large contribution that today’s internal combustions engine powered vehicles play in this equation. Hybrid vehicles appear to be a likely acceptable alternative to help reduce these exhaust emission gases, such as carbon dioxide, nitrogen oxide, and carbon monoxide and sulfur oxides. (EPA Sources of

The electric car can reduce the pollutants in the air as itself it produces no emissions. Furthermore, with the varied spread of power plants in use today in the U.S. An all electric fleet would produce forty percent less emissions than todays vehicles (Seamens). The electric motor also converts the stored electricity into movement more efficiently than an internal combustion engine. Estimated at one percent efficiency for the ICEV(Siemens), the electric motor experiences efficiency levels of sixty to eighty percent (Helmans). The inefficiency in both systems is energy lost as heat, noise, vibrations, and friction. With fewer moving parts the electric car loses less to
