Some Facts About Hybrid Cars In The Early Twenty-First Century

You would almost certainly be surprised to hear that hybrid cars have been with us since the very earliest days of automotive history, but you will not be astonished to be told that the technology has come on in leaps and bounds for the last ten years. In fact, the technology in hybrid cars has reached the level where fuel consumption in a hybrid can be half that of in a conventional internal combustion engine only car.

Half or even less than half under some circumstances like driving in town, especially in heavy traffic. In fact, while a hybrid is either cruising on electric or stopping and starting in thick traffic, there will be no consumption of petrol or diesel whatsoever, which means that you are driving ‘without cost’.
I put without cost in parentheses because a hybrid vehicle is still considerably dearer than a car with a traditional engine. However, even given the added price of a hybrid vehicle, you can save that excess cost over the average life time of the vehicle because of the saving on fuel. Obviously, the higher the cost of fuel, the sooner you will recover your extra initial outlay on the cost of the hybrid.

Perhaps you are thinking that hybrid vehicle manufacturers are profiteering on the backs of car drivers who would like to do their bit for the environment. Well, you would not be alone in thinking that, yet the cost of developing hybrid technology was and still is costly and someone has to account it.
That is you and me, the end-users. Well, that is standard, but in some countries, the government has stepped in to subsidize individuals who purchase a hybrid vehicle, because governments all over the world are under an oath to reduce their country’s carbon footprint.
That means that now is as good a time as any to buy a hybrid vehicle.
There are other reasons why a hybrid is costly though. The hybrid actually has two engines. A hybrid has a traditional engine run on traditional fuels, yet it also has an electric engine which runs off costly batteries. It is not that you have to replace the batteries as with a radio. The batteries are costly because they are very heavy duty rechargeable units.
The technology for recharging these batteries is also ground-breaking. The car uses traditional alternators to recharge them but it also uses braking power to recharge them too. Not just that but the car’s on board computer switches between the two motors automatically, depending on the quantity of power that is needed by the driver.
Keep an eye on the hybrid car market because prices are declining and together with subsidies, the time to buy a hybrid car might come sooner than you imagine.

Honda recalls 37,000 Civic Hybrid cars in US

Honda recalls 37,000 Civic Hybrid cars in US

In the latest defect recall to hit Japanese automakers, Honda said Thursday it will recall nearly 37,000 Civic Hybrids in the United States.Honda said a faulty converter in the hybrid control system could lead to the engine stalling and malfunction of the headlights.
No injuries or accidents have been reported in relation to the problem, which affects 2006 and 2007 models.
It comes two weeks after Honda said it was recalling nearly 700,000 vehicles worldwide due to defective parts that could stall the engine and cause problems restarting in certain models.
Honda has now recalled more than four million vehicles since February 2010 over a range of different issues, while Nissan has pulled around 3.5 million in the same period.
Toyota became mired in crisis when it recalled nearly nine million vehicles between late 2009 and February last year due to brake and accelerator defects linked to deadly accidents that tarnished its image of reliability.
As criticism mounted of its slow response and bureaucratic inflexibility, Toyota tightened its recall policy and has pulled around 16 million units since late 2009 over a range of issues.

'Air hybrid' cars would be cheaper than electric hybrids, claims researcher

Storing energy as compressed air rather than in batteries would reduce the cost of green hybrid cars, say researchers in Sweden

 

Electric cars and electric hybrid cars already make use of brake energy to power a generator that charges the batteries. However, according to Per Tunestål, a researcher in Combustion Engines at Lund University in Sweden, air hybrids, or pneumatic hybrids as they are also known, would be much cheaper to manufacture.
"The technology is fully realistic. I was recently contacted by a vehicle manufacturer in India which wanted to start making air hybrids," he says.
The technology is particularly attractive for jerky and slow driving, for example for buses in urban traffic.
"My simulations show that buses in cities could reduce their fuel consumption by 60%," says Sasa Trajkovic, a doctoral student in Combustion Engines at Lund University who recently defended a thesis on the subject.
Trajkovic also calculated that 48% of the brake energy, which is compressed and saved in a small air tank connected to the engine, could be reused later. This means that the degree of reuse for air hybrids could match that of today's electric hybrids. The engine does not require any expensive materials and is therefore cheap to manufacture. It also takes up much less space than an electric hybrid engine. The method works with petrol, natural gas and diesel.
The idea of air hybrids was initially hit upon by Ford in the 1990s, but the American car company quickly shelved the plans because it lacked the necessary technology to move forward with the project. Today, research on air hybrids is conducted at ETH in Switzerland, Orléans in France and Lund University in Sweden. One company that intends to invest in engines with air hybrid technology is the American Scuderi. However, their only results so far have been from simulations, not from experiments.
"This is the first time anyone has done experiments in an actual engine," says Trajkovic. "The research so far has only been theoretical. In addition, we have used data that means we get credible driving cycle results, for example data from the driving patterns of buses in New York."
The researchers in Lund hope that the next step will be to convert their research results from a single cylinder to a complete, multi-cylinder engine. They would thus be able to move the concept one step closer to a real vehicle.
