Structures of Hybrid Vehicles

Structures of Hybrid Vehicles

Global warming has become a major issue in the past year. Although environmental issues are recognized, they are not given that much attention on a wider scale. Now, more and more people are becoming aware of how much mankind has affected the planet. The need for solutions is recognized more than ever to address environmental issues. Due to this hybrid cars are becoming increasingly popular to consumers.

The shift from conventional cars is not just because of environmental concerns but also due to soaring gas prices. Hybrid vehicles bridge the gap between using an SUV and caring for the environment. There have been lots of improvements in the hybrid technology as the millennium came and it will be just a matter of time before it dominates the fuel dependent dominated automobile industry. More »

Dodge Charger

Dodge Charger

In October 2007, a new B-Body Charger based on the 1970 models was shown in a Mopar magazine. The Dodge Charger is an American automobile manufactured by Chrysler, under the Dodge brand name. There have been several different Dodge vehicles, on three different platforms, bearing the Charger nameplate.

The name was also carried by a 1999 concept car that differed substantially from the Charger eventually placed into production for the 2006 model year. The Dodge Charger, is a rear-wheel drive full-size automobile. The Charger name is a historic one, borne by many other Dodge Charger models in the past.

Introduced in February 2005 for the 2006 model year, this new Charger shares the LX platform of the Chrysler 300 and the now discontinued Dodge Magnum, which borrows component parts from the Mercedes E-Class platform in fact, the interior of the Charger is almost identical to that of the Magnum.

It replaced the Dodge Intrepid as Dodge’s full-size sedan. This Charger is a four-door sedan, disappointing many fans of the previous two-door Chargers. The first Dodge Charger was the 1964 show car, based on the Polara and fitted with a 426 Wedge engine. (Allpar.com) The first Dodge Charger available for sale was in 1966.In 1999, Dodge came out with a new Charger R/T concept car.

The concept Charger R/T, while sharing the long nose and rearward cab of the original, was a lot shorter. It was 187 inches (4,700 mm) in overall length compared to 203 inches (5,200 mm) for the 1966 Charger. In Canada, the base model Charger has a 2.7 L V6, which produces 190 hp (142 kW) and 190 lb·ft (258 N·m) of torque. This engine produces 340 hp (254 kW) and 390 lb·ft (529 N·m) of torque.

The 6.1 L Hemi produces 425 hp (317 kW) and 420 lb·ft (569 N·m) of torque.All models including the SRT-8 and the SuperBee come standard with ESP or Electronic Stability Programing. ESP specifically redirects power from the rear tires during any increased tire spin either on dry or wet surface’s causing the vehicle to regain traction before a spinout can occur.

The Insurance Institute for Highway Safety gives the Charger an overall Good score in frontal crash tests. In side impacts Charger models equipped with optional side airbags are given a Marginal score overall, and models without side airbags are given the lowest overall Poor score

Both the SXT and R/T models are also available as AWD (All Wheel Drive) starting in 2007. The All-Wheel Drive system is derived from the Mercedes-Benz 4MATIC technology. From 2007-2008, the AWD system is engaged all the time, routing approximately 60% of the power to the rear wheels and 40% of the power to the front wheels. The 2009 Charger AWD utilized the Torque-on-Demand system manufactured by Borg Warner which disconnects the front axles until extra traction is needed.

Electric Propulsion Systems

Electric Propulsion Systems

Hybrids are planning to use electric propulsion systems which prove to be very efficient and also environmentally friendly. There may be various approaches and methods in order to accomplish movement using electric power but the main idea is still the same. These systems are already working and will further help develop alternate fuel.

What is Electric Propulsion?

Electric propulsion is the acceleration of gases in order to produce propulsive thrust through electric and magnetic body forces, electric body forces or electric heating. The electric propulsion system is usually incorporated in rocket science wherein it manages energy enough to produce a powerful thrust. An electric propulsion system is an alternative to nuclear propulsion system. The total thrust is less powerful compared to a nuclear rocket but still enough to produce effects.

According to a number of studies, any engine used as a primary source of such powerful propulsion must produce exhaust velocities of around 10 to 20 km/s. There are also storable chemical systems used in rockets with an exhaust velocity of around 5 km/s but overall is less efficient.

Propulsion systems that do not require energy through chemical reactions are still needed. There are electric propulsion thrusters able to produce exhaust velocities of around 10 to 20 km/s which increases payload and reduces propellant mass. The consequences however, are less powerful thrusters consuming larger quantities of power.

The 3 Categories of Electric Propulsion

Electro thermal propulsion is when the propellant is electrically heated then isentropically expanded through a C/D or convergent/divergent nozzle. The system works as electrical energy heats propellants that produce gases as a result. The gases are sent through the C/D nozzle creating thrust. Catalyzed hydrazine or another neutral gas is used in thrusters like arc jets and resistojets.

Arc jets can also be used to heat the propellants via an electrical arc discharge. The arc in the arc jet is a beam of electrons produced from the cathode tip then gathers at the anode. Since an arc jet has a cathode and an anode, a constrictor is also present which is a narrow pathway between the two charges.

Electrostatic thrusters are also called ion thrusters. These use an ionized propellant accelerated through electric fields applied directly like gridded ion thrusters and Hall thrusters. The technique of propulsion is also known as ion propulsion technique since ions are mainly used in the process. Electrostatic energy is used to produce propulsion.

A Brief Guide to Hybrid Vehicles

A Brief Guide to Hybrid Vehicles

Hybrid vehicles were the stuff of dreams centuries ago. Nobody ever thought that creating a vehicle independent from fuel was possible. Fortunately with the continuing development of hybrid technology, more efficient and practical vehicles have been created. In the recent years the campaign for global warming has brought the attention of the public. Hybrid cars are now becoming steadily popular available in different types from compact sedans to SUVs.

Environmental issues are not the only reason that has made the public favor hybrid cars. Rising gas prices is also one of the major reasons why people prefer hybrid cars than conventional ones. Its also practical in suburban environments where you don’t really need horsepower but gas mileage.

Hybrid vehicles

There are  different types of hybrid vehicles. They can vary from the simplest wheelbarrows to ships. No matter what form they are, these vehicles help in reducing greenhouse and noise emissions. Although these vehicles are expensive due to their unique structures, developments will continue to provide more alternatives to the public. These cars may not compare to conventional ones with a 200 horsepower but why would you need that if you only need 20 in the streets?

The simplest hybrid would be the single wheeled vehicles. These are wheelbarrows famously depicted with sails. This can be seen in Chinese sailing carriages.

The next is two wheeled vehicles. These are usually cycle type vehicles. The best example would be the Moped and electric bicycles. They are powered by an electric motor or an internal combustion engine in combination with the rider’s muscles. This concept was also used in the 1800’s by motorcycles. The electric bicycle can either be a parallel or a series hybrid.

Hybrid vehicles are not just limited to private cars. There are also hybrid power trains used by heavy vehicles. There are diesel or turbo electric buses, railway locomotives, heavy duty vehicles, hydraulic machinery and ships.

In ships a diesel engine drives the electric generator or hydraulic pump which in turn powers one or more hydraulic or electric motors. Sails and engines were early forms of hybrids which may be used again due to rising fuel costs.

More developments are continually being made in hybrid structures and systems for efficiency. Today buying a hybrid car is expensive but it will be beneficial in the long run. It does not just save fuel costs but also removes pollution that can harm the health of the people and take whatever it is left of the environment.

Midsize Hybrid Cars on the Market

Midsize Hybrid Cars on the Market

There are 4 competing midsize hybrid electric vehicles on the market: Honda Accord Hybrid, Toyota Camry, Lexus GS 450h, and the Nissan Altima Hybrid.

Honda Accord Hybrid. Even before the release of the Hybrid, the Honda Accord was the second best selling car in the country. But the Accord Hybrid did not live up to the title “best-seller”. After soaring success in 2005, car sales plummeted when its rival the Toyota Camry Hybrid hit the market. In 2007, the hybrid version of the Accord was discontinued.

However, buying an Accord Hybrid will give you a good 30mpg/37mpg fuel rating. Accord is run by a powerful 3.0 L engine that produces 240-hp and 232 lb.-ft at 5000 RPM of torque. The electric motor is 16-hp with 100 lb.-ft at 840 rpm of torque. The sticker price of the Honda Accord Hybrid is approx. $30,000. You cannot buy a brand new Accord Hybrid from Honda but that’s not the only place where you can buy a car, right?

Toyota Camry Hybrid. Camry is known for its comfort, safety, and dependability. And surely, these characteristics are carried out with the Toyota Camry Hybrid. Powered by 2.4-liter four-cylinder gasoline engine and 105-kW electric motor and 244-volt battery pack, the Camry can deliver a total of 192 horsepower. It promises to run 33mpg in the city and 34mpg on the highway. The Camry’s sticker price is at approx. $25,200. (The second generation Toyota Prius is classified as a midsize car.)

Lexus GS 450h. If you think that a hybrid should have a small engine, then, the Lexus GS 450h will change the way to think. This hybrid has 24-valve, 3.5-liter gasoline engine that produces 297-hp. That’s just the half of it. The electric motor-generator produces 197 hp giving the driver of this car the power and sheer adrenaline rush. But don’t be fooled, the Lexus GS 450h may perform like a sports car but it definitely has the luxury features you want in a midsize car. And why not? At the price of $55,000, you surely have to set high expectations.

Nissan Altima Hybrid. If you don’t like the Toyota Camry and can’t afford a Lexus GS 450h, then you can go for the Nissan Altima Hybrid. It is powered by a large 2.5-liter engine that produces 198 horsepower and 162 lb.-ft at 2800 RPM of torque. The Altima is only available in selected states including Vermont, Rhode Island, New York, New Jersey, Massachusetts, Maine, Connecticut, and California. Fuel economy is impressive considering the size of the engine. It is rated at 35mpg/33mpg and priced at approx. $25,100.
