Re: If you're hungry for power or fuel efficiency, beware of a scam like this one:

That's the web site which says: "Some people want to know how we eliminate the frictions. Sorry we do not disclose our invention / technique to general public."

That's correct sir, many people want to know our secrets, even BMW, and Mercedes-Benz. Understand this, you do not get detailed design from Honda / Toyota neither about their hybrid vehicles. They tell you briefly about their battery system to confuse you, in reality you get the most out of better mechanism and better chemical reaction. If your intention is to save fuel then you will be fine OFS.

We will explain in person how thing works, for example if you want extra horse power, we would ask your permission to do a little modification to your air intake (not all tune-up will need this requirement), the little change won't be noticeable outside your vehicle. You can do your regular oil change, air filter change etc.. Our tune-up won't interfere with your routine maintenance.

Let me remind you, severe economic stress is coming ahead, do not let it force you to make a practical decision the last minute, do plan ahead. We lower our prices substantially comparing to the last 3-yrs. You would want people with experience in electrical system, in computer logic processing, in better mechanism, and in chemistry to take good care of your car. Good luck with your decision.

PS. Energy is not created in the tailpipe like some people think, it's in your combustion. More Energy = Better compression + Reduced loads.

I'm more concerned about your fictions than my frictions [sic].

Thanks but don't be. I bet these guys are smarter than you, their thinking still have some flaws, they argued for 5 years with no result and we already got it done and tested.

They well may be (smarter than I), but I see absolutely no evidence of it. If they're correct, then (by parity of reasoning), running on LPG should be much more /fuel/ /efficient/ than running on liquid fuel.

It isn't.

In company with yourself, if their engineering is as good as their grammar and their logic, they should be avoided like the plague.

Good point, well made. LPG is half the price of petrol here to try and get people to take it up but it's reported in car magazines to be only about 85% as efficient as petrol.

Correct if you run propane alone. You guys make too quick assumption, you haven't studied any chemical transitions have you? I see many people on the internet playing too much with equations, no support evidences.

Any way remember, you're not on full horse power as autosellers want you to believe.

And of course, BMW and Mercedes are unable to come up with $1300 to buy one of your devices and then reverse engineer it. I can see that that would be a stumbling block for them.

Another flaw in your logic processing.

No, they want to own it outright, this is what they said "Show us first, No NDA".

Would you give your life saving away to the rich men?

As you're such a good manufacturer, how come you use a public news server (yahoo) instead of having your own? I think you're a one man back street rip off merchant.

ing.

Why would an auto manufacturer have to have anyone show it to them? All they have to do is get hold of one car that's been modified and see what's been done to it.

Anyone who can convert solid matter into a mathmatical measurement is selling themselves short if they only make millions.

By reversing the process they could have billions.

And when you say no, they buy one, reverse engineer it and make their version public putting you out of business.

If they stopped at the first no, they didn't think it was that important.

85% as efficient in an engine built to run petrol and tweaked to run LPG.

If an engine is built to run LPG, higher compression, stronger ignition system, more ignition advance, different ignition curve and a high boost turbo, you not only get higher performance, you also get similar instead of inferior fuel consumption levels, and retain the clean burning characteristics of LPG.

There's something wrong with your ideas. LPG or Propane is a shorter chain molecule than petrol and therefore will have a lower flash point than petrol, requiring if anything lower compression and certainly not more advanced timing than petrol. Increasing boost pressure allows more fuel to be burnt giving more power, but at the expense of greater fuel usage. So you still end up with only 85% efficiency compared to petrol. Don't forget what happened when the EU tried to get diesel engines to run on any fuel from diesel to petrol, after getting over the injection pump wear issues, it was found that petrol was sticking to the cylinder walls instead of a clean burn and a 25mpg diesel engine would only give about 13mpg when used with petrol.

Thanks Carl for your advice. I don't think it's easy to understand someone else's design. For instance, fixing dragging brake problem, you tried it 6-7 times, the same problem returns. That's why we don't disclose our technique. We have to sell short a little bit while pending for a patent.

------ For only 4% of a hybrid cost, OFS can turn any vehicle into a hybrid-like vehicle. It's called Fuel-Efficiency Tune-up. It increases gas mileage and horse power without harming the vehicle like the N2O technique.

Clive,

Chemically you describe things correctly but you said there is no gain from mixing LPG with gasoline, that is just your theory, it isn't a reality. I gain 8-10mpg on top of my 50mpg. Remember Gasoline and Propane are present at the same time, you get a quick and long burning stroke. LPG burns first then its heat burns any unburnt Gasoline making each stroke a more complete burn.

When I shut off my LPG tank, I can see a drop in horse power and in fuel efficiency by about 10mpg. 1-gallon of LPG is good for 14gallons of Gasoline. Any way do google for propane tanks for trucks, I've found a manufacturer in US selling them quite expensive around $900 a tank to be used with the same technique. Also do a search on a patent site, someone already file a patent for this idea.

I don't think mixing LPG for diesel engine is a good idea but I could be wrong.

The only thing I don't like about selling LPG mixture with Gasoline to general public is, it's dangerous with the way people handling the tank. Customers can blew themselves up easily and blame their problem on someone else.

Rubbish, the amount of fuel introduced into the cylinders is a stoichiometric ratio for complete combustion, adding more hydrocarbons (that's what LPG is) will destroy this mixture and lead to unburned fuel pouring out of the exhaust, polluting the atmosphere and costing money to the person that try's.

Just because you've filed a patent, it doesn't stop it being rubbish.

You'd be right, considering that diesel engines are compression ignition engines the chances of pre-ignition with LPG in the air could seriously damage the whole drive chain.

As cars can be bought on the open market as LPG or petrol at the flick of a switch known as Duel Fuel cars, again you are talking rubbish, or would that be garbage in your broken English.

Seriously, look into proper LPG optimisation.

LPG has a lower calorific value so requires more fuel, but has a higher octane so can handle more advance and compression before pre-ignition.

Using sequential injection rather than a simple gas ring in the inlet and the correct ignition and compression (or artificially raised through forced induction) you can at least equal petrol efficiency.

It isn't rocket science, LPG is the ideal for for turbo boosting and because of the better resistance to knock, you don't need to over-richen the mixture to reduce the risk of knock. Petrol and diesel engines very often run massively rich under boost to cool the engine to keep the knock down.
