Gasoline, Steam Engine Hybrid?


If somebody tells you that adding a little bit of water to your engine can get you 40% better mileage, they're probably blowing a lot of hot air. If Bruce Crower, winner of the 2007 Popular Science Invention Award tells you it's possible, be prepared to be blown away.

In today's gasoline and buy generic viagra diesel engines, the four strokes of official canadian pharmacy the piston - intake of air, compression of the air/fuel mixture, combustion of fuel, and exhaust of the resulting fumes - generates temperatures above 1500°F. Crower's new engine design harnesses this otherwise wasted heat by injecting water onto the blazing hot piston. The water instantly vaporizes  and expands in volume 1,600 times to power the piston through another two strokes. The resulting steam is then recaptured and fed through a condenser to only for you viagra online order be used again.

Not only does this increase the www.marthawashingtoninn.com amount of power produced by the engine by about 40%, it cools the engine as it operates, completely eliminating the need for a cooling system. No radiator, no coolant, no water pump... it could shave as much as 1000 lbs off the weight of semi-truck engines.

Best of we recommend cheap cialis pills all, the technology could be used in any kind of internal combustion engine. Gasoline, hybrid, series hybrid, biodiesel, and it would always save huge amounts of fuel.

No word yet on when we might see this in passenger cars, but the designer's credentials and a working prototype mean it's not more than a few years off.

"No radiator, no coolant, no water pump
written by Space, May 29, 2007
Where does the water condensates if there is no radiator?
And how is it injected in the cheap generic cialis india engine if there is no pump?
And isn't water being a coolant here?

This seems to be a cooling system that recycles some of the energy rather than just dissipate it entirely as heat.

"Where does the water condensates if there is no radiator?" Not to viagra mail order india sound like a jackass, but in the condenser like it says in the article. A radiator would make the most sense, but I guess that they might use a compressor. How they would drive it I don't know. Most likely belt driven in place of the water pump. I think an electric one would draw too many amps. I wish there were more technical specs on the idea.

"And how is it injected in the engine if there is no pump?"
I think they mean no more water pump in the traditional sense. One that is belt driven to run the coolant system. But there would most likely be a pump for the water like there is a pump for the gas lines. Electric, not belt driven. If I had to guess I would assume that the water is injected similar to how fuel is injected. And that would lead me to assume that it's also fuel injected. No need for a carburetor when you are already injecting something. However, I can't tell if there is a carb or not in the linking article's pict.

"And isn't water being a coolant here?
This seems to be a cooling system that recycles some of the energy rather than just dissipate it entirely as heat. "
Essentially yes. Heat is energy, so why not try to harness it, even if it is a byproduct, and use as much as we can?

Also this isn't as radical as it might seem. Turbo Prob airplanes did this several decades ago. Although the water injection wasn't on it's own stroke, it was with the order cialis online no prescription air fuel mixture.

I am a mechanic and inventor, I can fully understand the mechanics and the alterations needed for the injection process to be in time with each stroke. I can see using an alcohol based, such as window cleaner, in the winter time and using a magnetic oil heater to order viagra now make the starts easier. I do think there may need to be alterations for the heating system for the interior of the automobile, such as an electric heating system. The alternators of www.fashionunited.info today pump out a great deal of amps, especially for diesel engines. They have to produce enough power to operate the glow plugs and the electronic fuel injectors.
I had another idea in mind, but I believe this one will be the wave of the future, and running on green fuels.

No problems about water freezing the system ,they had these problems many years ago, and were taken care of. With all the levitra side effects replies of what should be done and prices cheapest levitra not be done, I bet there could be a real working steam hybrid engine that may be similiar to the subject at hand.

written by wewantutopia, February 17, 2008
"six times engine = power 50% below 4T engine"

Why would you think that? A four stroke cycle has only 1 power stroke while this 6 stroke cycle has 2 power strokes. 1/4 or 2/6. I looks like the 6 stoke will create more power

I have been running a steam hybrid system in my 96 Dakota off and on for a year, when working the mileage increases from 22 to about 32 miles per gallon ( been having pump problems ) Cost is less than 500 dollars but should run a bit less once the bugs are out.

I doubt that this design will work very well. Water and alcohol injection was used in the 1960s in the Olds Jetfire V-8s. Frankly those cars did not hold up well.
However the US Navy has used a better idea with great success. They inject sea water right inside the overseas buy viagra exhaust manifolds on some engines. The expanding steam adds more boost to the turbochargers. The Navy gets the extra power without exposing the guts of the engine to water. Obviously lugging around a lot of water would not work well for cars.

corrosion?
written by Milander, October 25, 2008
I'm not an engineer but it does seem to me that using water would add significantly to corrosion damage of the pistons due to the rapid boiling/vaporisation and would also lead to a severe loss of it's cool viagra pfizer life expectancy for the pistons.

if you wrap a small coper pipe round your exhaust pipe and fed water into it very slowly at one end and exhaust the other into the inlet manifol of the engine you get a very big improvement in mpg.

Hot metal cooler water?
written by Apostrophe, November 01, 2008
I agree with Milander, here. This may sound like a good idea in theory, but consider what happens to the hot piston and cylinder when you introduce water with a significantly lower temperature.
You get stress fractures. (not to mention possible corrosion)
This is not good for an engine.
It's possible that the piston won't get too hot, with water being introduced after every fuel detonation phase.. but it still doesn't sound like a good idea, to me.

Concerns
written by Paul, November 02, 2008
I think there could be concerns for stress cracking since you would be subjecting the internals to temperature extremes, this could be simply combated with use of the proper metals/alloys (which should already be there) as well as appropriate atomization. Radiant heat from the cylinder walls will heat up a "fine mist of air" before cold water ever touches the we choice cialis purchase cylinders. Keep in mind that the water being injected is most likely the same temperature as the fuel that has already been injected into cylinder. The water would only extract ~5% more energy or heat than gas would as it changes from a liquid to a gas. As far as corrosion, I wouldn't think that would be much to worry about since water is a majority of the byproducts produced during combustion (in ideal conditions). Not saying I'm an expert, but I am an engineer with experience with the chemistry, thermodynamics, and metallurgy involved in the concept of a 6 stroke engine. I personally feel its a fantastic idea, I've always had a problem with the fact that so much energy is lost to heat in a gas/diesel engine, kudos for someone coming up with a fantastic idea and sticking with it, I hope it is technology we see in the near future, lord knows my wallet could use it :P

This idea is best alone IF one has a late model car. Most newer cars have an iron block and aluminum heads. The temperature tolerances are critical. I had an overheating incident that lasted no more than 20 seconds or so in a 2001 Pontiac that resulted in a blown engine! By comparison, I had a similar, but far longer incident in a new 1976 Cadillac that resulted in no residual damage. Given the tolerances of viagra profesional the newer engines, I'd be reluctant to risk a couple of grand.
A better idea is to capture the now wasted heat from the exhaust and perhaps drive a modified flywheel equipped with turbine fins and a closed loop water/coolant system. This would be particularly effective on diesels.

But this just won't work. Sure it'll make steam until the engine seazes. But it will be low pressure steam, otherwise the www.kletterwald-sayn.de backpressure would just stop the piston. You can do much work without the pressure.

Gas / Water Engine

This is not a new technology at all. It's just been rediscovered. Something almost identical to this technology was developed during W.W.II for air craft engines to give them extra power; and it worked.

Not feasible in the real world
written by Bodydropt, September 22, 2013
Like many before me have said, thermal stress and www.markwellgroup.com.au corrosion alone make this a bad idea. I'd also like to point out that the "1000lb reduction in weight" is ludicrous. The last truck I drove had a 3406 Cat in it and held approx 12gal of coolant or about 75lbs. Cast iron is just under 450lbs/cubic foot. So over 2 cubic feet of cast iron would have to be removed (12"x12"x24") PLUS whatever extra to offset the new water injection system. A complete 3406 motor with flywheel weighs less than 3,000 lbs. I guess since all this magical power is there you plan to remove 1/3 of the entire engine? Also let's not overlook having to design entirely new cam/rocker/head setups for these motors. (Take note here Mr. "my Dodge Dakota has this") A 6 stroke system requires the valves to open every 3rd revolution. This is easily remedied with different timing sprockets/chain. BUT this system needs a 3rd type of valve (intake/exhaust/steam) that doesn't exist in traditional 4 stroke engines thus needing new head/cam designs. This creates another problem: where/how to plumb the steam out of the heads and into the condenser. Lastly (because I'm tired of typing, not because I'm out of problems with this design) this condenser is going to have to be LARGE. And most likely look a LOT like the radiator/inter-cooler currently sitting in front of the best choice 5mg viagra a 3406.

To the OP: I'm not saying this isn't a cool idea; but I don't approve of you selling the public a dream you know NOTHING about. Post a link to the article you found on your FailBook page and get a real job. Feel free to contact me if you feel I've posted anything false.

That's not how it works...
written by NathanF, January 22, 2014
I love the www.americanfoods.com people who are commenting that we already have water injection...

Water injection in an internal combustion engine has absolutely nothing to do with this. Water injection in the traditional sense is the use of thin sprays of water into the combustion chamber to cool and prevent the early combustion of the fuel/air mixture in excessively high compression motors.

The idea expressed in this article is a novel one at the very basics, recycling the heat into steam to create an extra power stroke. But there's about a million little problems that would prevent this from working.

In addition to the stuff Bodydropt

#1 there's not enough heat energy left in the combustion chamber for sprayed water to expand enough to create a power stroke. In a normal steam engine high pressure steam is stored in a chamber outside of the cylinder and released into the chamber to push the piston.

#2 Water vapor would need to be COMPLETELY scavenged from the combustion chamber. While combustion can still occur with water in the chamber (See water injection prior) it still absorbs some of the energy released in combustion, making for a weaker power stroke.

In the end it's not feasible.

So instead of four stroke engine you have a 6 stroke engine with power being generated in the 3rd and 6th strokes. That is, instead of 1 power stroke in 4 strokes, you would now have 1 power stoke in 3 strokes. I think you maybe a way be able to achieve greater power density with fewer strokes per power stroke, while concurrently reducing waste heat to the radiators, using it instead to power the motor.

Cooler pistons and buy viagra us cylinder walls may eliminate the need to circulate water inside the engine, further reducing the www.worcestercountybar.org weight of the engine. This may be offset if one still needs to resort to fins for additional air cooling.

Energy used to heat water to steam is lost, thus it would be best to inject water at close to it's boiling temp.
