Green car technology

A technology that uses hydrogen to reduce emissions from petrol-burning cars could be on the market in three years. It’s taken decades for the message to get through, but at last we are turning to greener motoring. The demand for hybrid cars in the UK is at an all-time high and waiting lists for the proven technology are long. In Japan, drivers have been shaken so seriously by the oil shocks that they became the first in the developed world to experience declining car ownership. They are also poised to benefit from the biggest experiment with electric cars since the milk float.

This is all terribly green and worthy, but these solutions mean forking out for another car. Wouldn’t it be better to adapt our existing vehicles? And while giving up our gas-guzzlers is one thing, what should we do with the billions of old-tech cars already on the road? After all, simply to scrap them means building new cars. As Conor Faughnan of the AA points out: “Most of the pollution associated with cars actually relates to their construction.” (more…)

Transform car engine’s heat into power

Steam power may have an old-fashioned image, but British engineers think it can improve the efficiency of the internal combustion engine

Say “steam power” and you conjure up images of Stevenson’s rocket, Isambard Kingdom Brunel and the heyday of the Victorian railways – romantic, but hardly the stuff of a clean, cutting-edge technology.

But steam could be about to make a comeback thanks to a company that is trying to make the internal combustion engine more efficient.

Clean Power Technologies, in Newhaven on the English south coast, is developing steam hybrid engines that claw back some of the immense amount of energy wasted by the internal combustion engine. Ultimately they aim to develop a car engine that runs partly on steam power. (more…)

Killing engine increases gas-powered car efficiency

The Second Fuel Friendly Fundamental: Your car wastes the most fuel when it’s stopped with the engine running; your mileage drops to zero. (Or – How to increase gas mileage by shutting off your engine.)

[Safety Note: Discovering how to increase gas mileage by shutting off your engine should never involve creating hazardous driving conditions. The advice on shutting off your engine does NOT apply to stop lights or other traffic conditions on the road.]

With that understanding, here are some more super easy ways to save gas.

THE WARM UP

In most circumstances, it does little good to warm your car up before driving. You save fuel if you just start your engine and go. But if you don’t warm up a bit when outside temperatures are below freezing, you have a good chance of frosting up the inside of your windows and hurting your visibility. (more…)

Options for engine technology

Alternative engine technologies are generating a lot of excitement. They either deliver better fuel economy or give the owner the flexibility to burn alternative ethanol-based fuels instead of imported oil. Should you pay extra for a higher mileage power plant or stay with a more conventional gas engine? Either way, it’s a calculated risk.

With the gas engine you save money now and hope the price of gas doesn’t go too high. With the high mileage option, you spend more now thinking that the price of gas will stay high or get worse.

Of course, if you do pay the extra money for the high mileage option and the price of gas drops, you still stay ahead of gas prices more than with a conventional gas engine. And there are other reasons to pay for the higher mileage option. (more…)

Fuel consumption by brake utilization

Whether you’re an engine builder or engaged in testing them on an engine dynamometer, a clear and working understanding of brake-specific fuel consumption (BSFC) can be of value. The broader category includes parts designers and those interested in evaluating power level changes involving parts or modifications. In one way or another, any changes in power (positive or negative) can be linked to combustion efficiency. And, simply stated, BSFC is keyed to this as well. Despite previous discussions about the subject, we’ll expand on it a bit in this presentation.

Now, although “Enginology” is not intended to include an array of mathematical calculations in support of the information provided, it’s worth noting how to compute BSFC because that will help in understanding the importance of its numerical relationships. In the English system of units, the computation involves fuel flow in pounds per hour (pph) and “observed” horsepower (uncorrected for barometric pressure and inlet air temperature). Arithmetically, if we divide fuel flow by observed horsepower, the units of measure will be pounds/horsepower-hour. That’s the academic perspective. (more…)

Create seal for racing

In what the old timers called the “good old days,” blown head gaskets used to be a real pain in the…well, you pick the body part. Poor machining practices that left the decks of both the heads and the block wavy, subpar bolts that weren’t torqued accurately, and old-school head gaskets left a lot to be desired. And that’s why all those additional practices popped up to help increase the chances of getting a long-lasting head gasket seal.

Of course, if you’re racing a 1,000-plus-hp dragster with forced induction or nitrous, then things like spraying your gaskets with a copper sealant or O-ringing the block may still be necessary. But for modern circle track racing engines, all that should be required are the right gaskets, good machining of the block and heads, some quality head bolts and—probably most important—proper installation practices.

New technology of car engine amazed Auto industry

Despite shifting into higher gear within the consumer’s green conscience, hybrid vehicles are still tethered to the gas pump via a fuel-thirsty 100-year-old invention: the internal combustion engine.

However, researchers at Michigan State University have built a prototype gasoline engine that requires no transmission, crankshaft, pistons, valves, fuel compression, cooling systems or fluids. Their so-called Wave Disk Generator could greatly improve the efficiency of gas-electric hybrid automobiles and potentially decrease auto emissions up to 90 percent when compared with conventional combustion engines.

The engine has a rotor that’s equipped with wave-like channels that trap and mix oxygen and fuel as the rotor spins. These central inlets are blocked off, building pressure within the chamber, causing a shock wave that ignites the compressed air and fuel to transmit energy. (more…)

Sophisticated water-based energy

There is some old karma around water that needs to be attended to.

Water in its primal form is a mirror to human consciousness and can be whatever the dreamer perceives. It is the medium that Consciousness forms to make the realities we all live. Water is Life itself. Without water, Earth would resemble Mars.

I have been studying water for a long time, not only its possible natures within the human body but also possible applications of water to help heal our planetary situation. Knowing this central position of water to the Mandala of Life, all research was performed with understanding of the sacredness of this medium to All Life Everywhere.

Most of this research has completed itself by a resulting understanding or experience. But some of this research has not completed itself. (more…)
