A hybrid vehicle combines any two power(energy) sources. Possible combinations include diesel/electric, gasoline/flywheel, and fuel cell/battery. Typically one energy source is storage and other is conversion of a fuel to energy. Throughout this essay, the word ’engine’ is used to denote the gasoline or diesel engine. Further the word ‘motor’ signifies an electric motor or the motor/generator(M/G).
A hybrid vehicle may consist of a gasoline engine combined with an M/G. A hybrid electric vehicle is formed by merging components from a pure electrical vehicle and a pure gasoline vehicle. HEVs reuire a smaller engine than a conventional vehicle as the electric motor can serve as a power-assist. The electric vehicle(EV) has an M/G which allows regenerative braking for an EV; the M/G installed in the HEV enables regenerative braking. For the HEV, the M/G is tucked directly behind the engine. In Honda hybrids, the M/G is connected directly to the engine. The transmission appears next in line. This arrangement has two torque producers; the M/G in motor mode, M-mode and the gasoline engine. The battery and M/G are connected electrically.
One new component, control system, has been added. The control system can enhance driving experience. Mixing propulsion from the engine and M/G opens many new control dilemmas to be solved and decisions to be made. Major functions are to maximize miles per gallon(mpg) and minimize exhaust emissions. Integration of mechanical components, electrical components, and the control software is as important as hardware. Integration and software challenges are enormous. Components must engage and disengage smootly.
Numerous minor functions of the control system include component protection by monitoring battery ...

...wer distribution system is seperated into two parts at vastly different power levels and voltages. One part is the “smarts” section or information section which is mainly computers and microprocessors (low power, low voltage). Another part is the muscle section or the power electronics that manages the power to the M/G and to the battery(high power,high voltage)
Hybrid electric vehicle are inherently expensive because of the extra components compared to a conventional vehicle(CV). The M/G and the large, high-voltage battery add to the cost. The HEV needs complex power management involving the HEV information(computers, software, algorithms, etc.) and HEV power(power transistors, cooling system, etc). The control system is extremely complicated and represents a tremendous challenge; it is not easy.
There are three common design options: series, parallel, and mixed.
Detroit asserts that the Cadillac engine system is responsible for cost reduction especially with regard to the Cadillac maintenance (73). This owes to the fact that the flexible logistics of installation and low consumption of fuel guarantee savings. This vehicle’s engine is efficient due to the fact that it is safe to drive at high and low speeds. The brake system of this vehicle does not require electromagnetic fields in order to function. The model in question is also fitted with emergency tools, which help in case of skidding. These tools include the braking cruise control. Cadillac’s brake system is light unlike other vehicles’ brake systems, and this enhances swiftness in driving the Cadillac. Additionally, this model does not have the shortcoming of fuel loss especially through drags. The Cadillac has Eigen solver system, which is responsible for squeal analysis. In this regard, the need for programming is eliminated. The thermoregulation ensures that the braking system’s heat is controlled. Furthermore, the thermoregulation amplifies the computation performance of squeal. The engine...
Cars are a necessary part of our lives today. However, we also drive cars which suit our personal tastes and for pure enjoyment. Your car makes a major statement about your personality. Your vehicles are also a major investment and you want to do everything you can to keep them looking good for a long time. No matter what type of vehicle you have, whether it is a new car or a classic you should cover it with a car cover when not in use.
Driven in large part by global initiatives and the potential for stringent regulations, the past decade or two has seen a marked increase in the importance of improvements with respect to environmental standards, including emissions and increases in fuel economy. In 2002, Cummins Emissions Solutions was launched after the need was identified for an emission solution that would help engines meet future regulations. In 2006, Cummins pioneered a hybrid diesel-electric bus which reduced fuel consumption and greenhouse gasses by more than 30 percent and me...
According to Cars Direct website, hybrid cars can reach 51 MPG wish destroy all gasoline and diesel efficiency expectations. This high efficiency yield to two main reasons: hybrid car tend to be lightweight, and the cooperating between the gasoline engine and the electric motor. ” According to consumer reports tests, most hybrid cars have better fuel economy than their gas-only counterparts “ (Barett, “The Difference Between Gas and Hybrid Vehicles”). This is obvious if we compare between a hybrid and gasoline cars which have the same name: the hybrid Honda civic average efficiency is 40 MPG while the standard Honda civic average efficiency is 29 MPG, the hybrid Hyundai sonata average efficiency is 33 MPG while the standard Hyundai sonata average efficiency is 27 MPG, and the hybrid Ford fusion average efficiency is 34 MPG while the standard Ford fusion average efficiency is 24 MPG (Barett) [average efficiency is the average between the car efficiency in city and its efficiency in highway
Another engine type is the hybrid engine. The hybrid involves both the use of a gasoline engine and an electrical engine.
A hybrid vehicle uses multiple propulsion systems to provide motive power. This most commonly refers to gasoline-electric hybrid vehicles, which use gasoline (petrol) to power internal-combustion engines (ICEs), and electric batteries to power electric motors. Modern mass-produced hybrids, such as the Toyota Prius, recharge their batteries by capturing kinetic energy via regenerative braking. As well, when cruising or idling, some of the output of the combustion engine is fed to a generator (merely the electric motor(s) running in generator mode[1]) which produces electricity to charge the batteries. This contrasts with all-electric cars which use batteries charged by an external source such as the grid, or a range extending trailer. Nearly all hybrids still require gasoline as their sole fuel source though diesel and other fuels such as ethanol or plant based oils have also seen occasional use.
The beginning of hybrid cars goes back to the 20th century. The Paris Exposition of 1900 included the Lohner-Porsche Elektromobil which is the first ever hybrid car. The inventor of the Lohner-Porsche Elektromobil was a 23 year old engineer named Ferdinand Porsche. Porsche is known today for his Volkswagen cars and for the famous sport cars designed by his son. He created a vehicle that could travel 38 miles on electricity alone. Porsche partnered with Jacob Lohner who wanted to develop motorcars that had incorporated coaches. The gas-powered cars at that time were very noisy and difficult to start. Porsche created battery-powered electric motors and put them in the front-wheel hubs to produce a front-wheel drive car. He also added an internal combustion gasoline engine so the batteries in the car could be charged. Sadly, the Lohner-Porsche could only reach up to 35 miles an hour. The idea of hybrid cars decreased during the years of growth in the modern automobile industry. This period brought a national highway system in the United States and gasoline was inexpensive. The concerns with auto emissions brought back the idea of hybrid cars. C. Russell Feldman, one of the founders of Motorola, decided to explore the possibilities of hybrid cars again. He contacted an electrical engineer named Victor Wouk to see if a hybrid car could work in society. Wouk found out that the batteries in the hybrid cars did not have the energy to produce a lot of speed and range. In the 1960’s, Wouk combined the low-emissions benefit of an electric car with the power and range of a gasoline engine to create a hybrid car. To make his hybrid car ideas real, Victor Wouk and his partner Charles Rosen formed the company called the Petro-E...
A hybrid vehicle is a vehicle that is powered by two or more power sources to move the vehicle (Lampton 2009). Among the types of power sources are electricity, petrol, and hydrogen gas. As of 2011, the world’s best selling hybrid, the Toyota Prius, on sale since 1997 has sold over 3 million units worldwide. Sales of other hybrids are also picking up. (Schwartz 2011)
Since the release of this first mass-produced of the hybrid vehicles the government has been doing a lot of things possible to be involved and also to regulate the purchasing’s of HEVs and PHEVs. Today, the President Obama has created a New Energy For America to plan for changes to its way the United States uses energy. The plan does include a section on the hybrid vehicles and plug-in hybrids. Soon the tax credits will be ended for its regular hybrid electrics vehicles. Now it is known, due to the rapid rate of the HEV sales the government has also withdrawn its tax rebates on HEV models, by giving exclusive tax cuts on EV and PHEV models, which based on its total electric charge that the battery pack can hold. Since then, HEV cars were popular among environmentally conscious drivers.
Most people today fill up their car with different qualities of petrol, because that's what the average car takes. They don't usually consider an alternative for the petrol that they load into their cars. Although petrol is widely used, it is not the only source for a car to get its power from; diesel and electricity are alternatives to the general petrol used by most cars. Although different from each other, diesel and electricity are alternatives to the average gasoline received at a gas station. Diesel is a more concentrated type of fuel that is usually used by big automobiles because they require a lot of power in a little amount of time. Electricity is a method that uses the power of batteries to produce a low horsepower but, nevertheless fast automobile. Electric cars are generally created to be soundless and environment friendly. The purpose of this paper is to classify and educate the reader of the different types of fuel available for an automobile to use: petrol, diesel, and electricity. The general petrol, used by most people, is usually the only type of fuel accepted on the average car in the United States today.
There are two configurations for hybrid cars. The first configuration uses gasoline engine to run a generator. The generator supplies electricity to the motor, which drives the wheels, which allows the gasoline engine to run constantly while achieving optimum fuel efficiency. This thereby minimizes emissions owing to incomplete combustion. A hybrid car with parallel configurations uses both an engine and a motor to drive the wheels depending on driving conditions. "A hybrid car is an automotive equipped with two or more sources of motive energy" (http://www.howstuffworks.com/hybrid-car1.htm).
Today, people use their own personal vehicles to travel more than ever before. Personal transportation is no longer considered a luxury; it is now considered a necessity. The number of cars in the United States has been growing steadily since the 1970s. The number of miles traveled by cars has risen nearly 150 percent, yet the United States population has only grown roughly 40 percent during that time (hybridcars.com, Driving Trends). Although it may seem like we are advancing into the future, in reality, we are moving backwards from the effects these vehicles have on our bodies and the environment. The pollution produced by these vehicles has brought us to the day where we must find other modes of transportation that cause less harm to the world in which we live. Advances in technology have developed hybrid vehicles to try and slow down the amount of pollution. Driving a hybrid vehicle, instead of a conventional gas powered vehicle, can reduce the amount of pollution that affects our lives and the environment around us.
Today, Hybrid cars are popular. Hybrid car works on a combination between electric and fuels. The engine powered by oil and that of the engine support by an electric charge. Engine is used to move the car, only when electric motors are extremely slow and measured speed. For instances, When the car needs additional power, such as that of steep hill or climbing up, gasoline motor can be used to add an extra boost to the engine. To go on th...
During the past few years, there has been an increasing concern over our use of gasoline in cars. There are a few answers to this concern. One of the first and most viable answers is the electric car. These vehicles are made up of a few components that help them run just like a normal car. The components to a direct current (DC) electric vehicle are the batteries, the controller and potentiometer, the motor and a specialized
Vehicles in this day and time are nothing like what they used to be. Over half of the car manufacturers are now trying to build new cars and trucks to be as fuel efficient as they can be. Although hybrids conserve more gas than standard vehicles do, they use gas, also. Hybrids do not use as much gas as the ol...
