Hybrids Today and Tommorow

0 comments
Hybrid vehicles have gone through many changes over the years. Ever since the Toyota Prius came out, bigger and more equipped hybrids were released. The Ford Escape hybrid came out in 2004, which jumpstarted the production of luxury hybrid cars. Apart from Toyota, Honda and Ford other automobile companies such as Mazda, Nissan and recently Lexus and Chevrolet have manufactured their own hybrid creations.

Early hybrid vehicles were limited to manual transmissions and air-conditioning. The best thing that they could do at the time of Toyota Prius was add a multiple CD changer. Nowadays customers have more options with Sports Utility Vehicles and luxury car hybrids. Apart from comfort settings and additional accessories, more formidable propulsion management systems are used.

Hybridization in the present and what lies ahead.

Last year luxury sedans and Sport Utility Vehicles were released. These environment friendly cars were also fitted with all the trappings and perks of a luxury vehicle. Apart from having the latest technology from their manufacturers, such as the Hybrid Synergy System from Toyota, they are also decked out with touch navigational systems, surround sound with DVD and VCD supporting stereo systems, ventilation seats, and multiple CD changers on the dashboard.

Hybrid vehicles released last year have V6 engines such as the Lexus GS 450 and V8 such as the Chevrolet Tahoe. Gear-ratio steering, continuous variable transmission, variable suspension, and regenerative breaking are standard among luxury car hybrids.

Hybrids that will be released in 2008 feature the Cadillac Escalade. It is a two mode hybrid with 6 liter V8 engine with two motors. The Saturn Green Line Vue will also be in the line up that promises to 45% improvement in fuel efficiency. Ford will launch its first hybrid sedan with Mercury Milan Hybrid. Mercedes will also release the hybrid version of their S-class sedan. Porsche also plans to launch its four door coupe called the Panamera, using the same technology as the Cayenne SUV.

If your head is getting dizzy with all the prices of the luxury cars Hyundai will release a hybrid available at around $10,000. This will be the first full hybrid under $20,000. Honda will release a smaller and more affordable hybrid to compete with Toyota who dominates the market.

No matter which hybrid vehicle you will choose, expect more hybrids to come. In time as gas prices soar and the demand for higher emissions regulations are implemented, hybrids will eventually dominate the market.

Mankind has made a huge impact on the environment. Although science and technology are continually progressing, it is also the cause of the planet's deterioration. Natural resources are being depleted to sustain the demand of a growing population. Although we have been gifted with logic and reasoning we are also prone to excess and carelessness that will inevitably bring about our demise. Although eradicated species and holes in the ozone layer can't be restored, scientists are finding ways to help the environment and maintain whatever it has left.

One of the main contributors of pollution is cars. Transportation is a necessity so this problem is not easy to solve. Scientists and automotive companies have come up with a solution for environmental conscious customers. Hybrid vehicles were created to answer environmental issues and provide alternatives for customers.

What is a hybrid?

A hybrid vehicle is a type of automobile that depends on different power sources other than fuel (ex. diesel, petrol). These vehicles are either powered by internal combustion engines, electric motors, or a fuel cell and a rechargeable energy storage system. These types of power sources can be applied to different type of vehicles for public and private transportation.

Automotive companies today are continually developing this technology to be able to cater environmental friendly cars and deliver quality brand vehicles at the same time. They are turning to popular type of vehicles such as SUV's to expand the appeal of hybrid technology.

Hybrid vehicles were designed to reduce emissions and save fuel. With the continuing rise of gas prices and global warming campaigns, more people are searching for alternatives to decrease dependence on fuel. This technology will also contribute to the general health of the public because car emissions pose a threat to one's health.

These vehicles are able to achieve this purpose in four ways. It shuts down the diesel engine during stops or idle periods. It has a battery storage that enables it to store and reuse the energy that it has recaptured. It's able to recapture energy that is usually wasted while breaking. It relies on two power sources, the diesel engine and the electric motors to reduce fuel consumption during peak power usage.

This type of vehicle is very convenient for traffic ridden areas. It also reduces noise emissions when the vehicle is operating at low speeds. Hybrid vehicles are practical and convenient cars for everyday living in the city.

History of Modern Transportation

People may be surprised to know that the idea of electric and hybrid vehicles have been present even before the gasoline engine was invented. A lot of people with their brilliant ideas revolutionized modern transportation as it is today. With the rise of health-threatening pollutants, new age electric and hybrid vehicles are truly becoming a reality.

When Electric Cars Ruled the World

Robert Anderson from Scotland created the first electric carriage during the 1830s. Professor Stratingh of Groningen from Holland designed a simple electric car. Christopher Becker was Stratingh's assistant who built the model in 1835. In 1842, Thomas Davenport from the United States and Robert Davidson from Scotland built more advanced electric vehicles with the use of non-rechargeable electric cells. Gaston Plante from France improved the storage battery and created a better model in 1865. Sixteen years later, Camille Faure continued to improve the storage battery.

During the late 1800s, several European nations like Great Britain and France began the spread of electric vehicles while constantly innovating for better design and performance. Electric cars did not need gear changes. The United States followed with the creation of electric tricycles. At the turn of the century, electric cars were selling better compared to their gasoline engine counterparts due to less vibration, noise and pollutants. In 1916, Woods invented the first hybrid consisting of an electric motor and combustion engine.

The cost of electric vehicles was somewhat expensive so only the people belonging in the upper class were able to afford them. Prices would reach $2,000 to $3,000 depending on the interior and materials used. Production peak for electric vehicles were from 1910 to 1912. During the 1920s, road systems were significantly improved so people needed vehicles that traveled farther than electric cars.

The price of gasoline also decreased making it more affordable for everyone. Charles Kettering invented the electric starter for gasoline cars taking away the tedious hand crank. Henry Ford and his idea of mass production at lower costs continued to reduce the popularity of electric cars. Gasoline cars at this point were only about one-third the price of an electric vehicle.

Decline and Regrowth

From 1935 to 1960, electric vehicles were slowly fading from the scene. However, people began looking for alternative fueled vehicles in order to solve problems on pollution and the growing price of gasoline. More practical models of electric vehicles were proposed.

A number of actions were also imposed in the United States and across the globe to exert effort in improving electric vehicles. Some great works were the U.S. 1990 Clean Air Act Amendment as well as the U.S. 1992 Energy Policy Act. Other states required vehicles to have zero emission. Some of the largest automobile manufacturers as well as the U.S. Department of Energy collaborated to start making hybrids. Mileage, speed and performance were greatly enhanced in these newer models.

Recent electric and hybrid models are able to generate energy through special energy-converting systems. Hybrid models had special dual engines running on both gasoline and electricity which helped conserve a lot of fuel aside from being environmentally friendly. Sedans, SUVs and trucks were quickly built using the newly discovered technology. The method of running on electricity had various approaches but the main idea of being conservative and green was present in all models.

Hybrids: The Pollution Solution

Gasoline engines were proven to be reliable and powerful. However, the constant burning of gasoline released a variety of harmful gases like carbon dioxide, carbon monoxide, hydrocarbons and nitrogen oxide. These are also known as greenhouse gases which trap heat in the atmosphere instead of allowing it to go out into space. The result would be global warming wherein surface air temperatures and sub-surface temperatures in the ocean would rise.

Although there are also natural causes to global warming, vehicle emission significantly multiplies the rate spurring the creation of alternative fuel sources. Electric and hybrid vehicles have shown to be very promising in reducing the greenhouse effect. Pollution will be minimized greatly if more and more people will start relying on these newer models which do not emit any harmful gas at all. These vehicles are also very economical since there is no longer a need for crude oil which constantly is growing in price.

Different Types of Vehicles

Do you know how many types of vehicles there are in all? Since the creation of the first crude automobile, several models and types have been created to suit the needs of people. These were developed in order to provide a safe, efficient and economical means of transportation. Some are built for luxury, others for practicality and some for environmental purposes.

Cruder Forms

Vehicles were first made thousands of years ago. The earliest forms of vehicles were actually living things like horses, elephants and camels. With the invention of the wheel around 3000 B.C., chariots, carts and horse-drawn carriages came into existence. The wheel has certainly paved the way for modern transportation as it is still very much present today.

Cycles were created around the 19th century which comes in many forms. Bicycles are one of the most common types of vehicles available today. There are also tricycles, quadricycles and unicycles. These vehicles mainly use a chain that goes around the wheels for propulsion. Cycling is a very important action in order to keep the transportation balanced. Later on, motorcycles were invented which incorporated a motor engine instead of manual pedals.

Origin of Alternate Fuel Sources

Electric vehicles or EVs were invented in the 1830's which uses one or more electric motors. The rotary or linear motors propel the vehicle through the wheels. Linear motors are used by tracked vehicles such as trains and MRTs. There are several sources of energy used to move the vehicle like an on-board RESS or rechargeable energy storage system, batteries, on-board super capacitors and direct connection to energy-generating plants. Fuel cells and nuclear energy have also shown to be very viable in propelling vehicles.

Steam engines are another alternate fuel source which uses an external combustion engine or ECE. ECEs are less efficient compared to ICEs but proper configurations can be made for the fuel burner in order to emit very low amounts of carbon monoxide, nitrogen oxide and other harmful gases making it environmentally friendly in the process. Steam cars do have a problem when starting from cold leading to the development of flash boilers.

The Automobile

Automobiles are the most common type of vehicle. The majority of automobiles today are powered by gasoline or diesel engines. Automobiles use an internal combustion engine or ICE which can be highly polluting due to the constant burning of harmful gases. This type of vehicle has shown to be very powerful, convenient and aesthetic as well making it the most popular of all time.

Gasoline engine vehicles are lighter and able to work at optimum rotational speeds. The invention of the electric starter has boosted its popularity beating steam and electric cars in the process. Carburetor and fuel injection are some of the most useful discoveries in enhancing automobile performance.

There are various innovations in the engine allowing exhaust gases to be less harmful. Others combine efforts to minimize the greenhouse effect by reducing emissions to zero. Gasoline engines are capable of running with different ethanol concentrations. Some may run on 15%, 85% or even 100% ethanol. Fuel burn efficiency of gasoline engine vehicles are around 27%.

Diesel engine vehicles are more cost-effective compared to gasoline engine ones because of their 50% fuel burn efficiency. However, power and performance is also compromised due to less concentration of fuel. Diesel also releases exhaust gases into the atmosphere from soot particles. 100% biodiesel has been developed to improve the downside of these vehicles.

Other Transports

A train is a series of vehicles moving along a guided track or rail. A separate locomotive provides power to propel the entire train. Diesel or electricity is the usual energy source of trains while older versions were dominantly powered by steam engines. There are special kinds of trains with special tracks like rubber-tired underground, high-speed and monorails. Some trains can have more than one locomotive or coach.

A road train has a prime mover pulling one or more trailers. Trucks are the simpler version of this. Since the weight and maneuverability are a challenge, these vehicles often require several wheels for more control. Speed should also be watched meticulously to make travel as safe as possible. Diesel engines usually power big heavy trucks and road trains for fuel efficiency and power.

Other unique types of vehicles are amphibious vehicles and snowmobiles. Amphibians can run on both land and water making them very versatile. There are amphibious bicycles, cars, trucks and ATVs developed for passenger and official use.

The advantages provided by amphibians made them very useful for military operations. Snowmobiles are propelled by a built-in track made of Kevlar composite or rubber in order to effectively move through snow. These are also powered by a motor engine that consumes gas for fuel. Tanks use the same mechanism as snowmobiles by running on steel tracks.
