Hybrid car Essay
The evolution of Electric Vehicle: The electric vehicle was started and generally divided into three parts: The early years (1890-1929) with their golden Age of dominance in the market from about 1895 to 1905: the middle years (1930-1989: and the current years (1990-present). In the early years, England and France were the first nation to experiment with the electric vehicles with the united state showing some interest in about 1895. Politics: The first steam road locomotive (automobile) began using public roadways, the automotive industry has been affected by laws And regulation. Today the transportation sector of the U.
S. economy is the major energy consumer. The automotive technology developer tends to look at the government as one of the many groups they need to deal with along with the utilities, the oil industry and the automotive industry. Of these various factor, only the government has the official role of shaping civic duties of citizenship. Government become involved for the public interest when citizen group wish to promote specific products for the public good interest or industries need assistance in research and development costs in research of products that have political potential.
Technology: The beginning of the new era of technology is comparable to the days when Gottlieb Daimler and Karl Benz were constructing the first vehicle power by internal combustion. The mechanism of an electric car is so simple that there are really two things upon which there can be any extensive improvement. Today, technological innovation is needed for the electric vehicle. The public must have a comparable product in the price and performance to move from their internal combustion engine (ICE).
The technology that i9s being created today points on to solutions that will allow automobile manufacturers to produce an environmental friendly electric vehicle that is better than the conventional technology currently used and at the competitive price. Hybrid Structure Gasoline-electric hybrid cars contain the following parts: • Gasoline engine – The hybrid car has a gasoline engine much like the one you will find on most cars. However, the engine on a hybrid is smaller and uses advanced technologies to reduce emissions and increase efficiency.
• Fuel tank – The fuel tank in a hybrid is the energy storage device for the gasoline engine. Gasoline has a much higher energy density than batteries do. For example, it takes about 1,000 pounds of batteries to store as much energy as 1 gallon (7 pounds) of gasoline. • Electric motor – The electric motor on a hybrid car is very sophisticated. Advanced electronics allow it to act as a motor as well as a generator. For example, when it needs to, it can draw energy from the batteries to accelerate the car. But acting as a generator, it can slow the car down and return energy to the batteries.
• Generator – The generator is similar to an electric motor, but it acts only to produce electrical power. It is used mostly on series hybrids (see below). • Batteries – The batteries in a hybrid car are the energy storage device for the electric motor. Unlike the gasoline in the fuel tank, which can only power the gasoline engine, the electric motor on a hybrid car can put energy into the batteries as well as draw energy from them. • Transmission – The transmission on a hybrid car performs the same basic function as the transmission on a conventional car.
Some hybrids, like the Honda Insight, have conventional transmissions. Others, like the Toyota Prius, have radically different ones, which we’ll talk about later. Hybrid cars also gain efficiency from: 1. Smaller and more efficient engines. 2. Regenerative braking – the electric motor that drives the hybrid can also slow the car. In this mode, the electric motor acts as a generator and charges the batteries while the car is slowing down. 3. Periodic engine shut off – when a hybrid car is stopped in traffic, the engine is temporarily shut off.
It restarts automatically when put back into gear. 4. Advanced aerodynamics – to reduce drag 5. Low-rolling resistance (LLR) tires – narrow, stiffer tires have less drag Lightweight materials – increase the efficiency of hybrid cars.
