Thank god they didn't say you'll be able to start off in 5th gear directly!!

I was wondering, whom are they trying to cheat? Will an average educated car owner fall for this? I don't think so.

I think the ad say every thing as "UPTO". So they are theoretically correct.

Upto 100% implies <= 100%.

So the ad is correct even if there is increase of 0% in power/efficiency.

What this device is supposed to do is what is known technically as hot air induction.

What it is supposed to do:

Quote:
Function
The hot air intake functions by drawing in air from near the engine, which has been heated due to internal combustion. This warm air causes the fuel mixture in the car to drop, thereby lessening how much fuel is used and increasing mileage.
Types
Hot air intakes can be purchased in kits or built in a do-it-yourself fashion. Kits are generally more effective at increasing gas mileage, but DIY construction saves money on the initial investment.
Identification
To identify a hot air intake, look for a rubber or metal hose coming out of the engine, passing through an air filter, with an opening somewhere near the engine block or radiator.
Size
Warm air intakes add some bulk to the engine in terms of space, since extra hoses have to be installed, but they only weigh a few pounds so they have no weight-related adverse effects on the engine. However they can still provide an excellent boost to gas mileage.
Warning
Before installing a hot air intake, you should check with the manufacturer of your vehicle to ensure that the vehicle will not be adversely affected, as some cars have specialized engines that should not be modified in an attempt to increase gas mileage.

From The Effects of the Hot Air Intake on Gas Mileage | eHow.com
Why it is supposed to work, and how to build it at home:

Quote:
How to build your own Warm Air Intake (WAI) - GasSavers.org - Helping You Save at the Pump Hypermiling and Fuel Efficiency Forum

From the same link:

Cold air intakes will produce more power, and will save gas if the engine operates only at Wide Open Throttle.

However, under 90% of driving, Warm Air Intakes are more efficient because the engine is throttled and under less than full load. WAI does two things:

1) Fuel evaporates more quickly, increasing combustion speed. Fast burn engines improves the amount of pressure generated and expansion work available for a given amount of fuel.

2) With oxygen sensors, engines run at stoichiometric air/fuel ratios. For any given amount of fuel, a corresponding mass of oxygen is admitted. WAI lowers the density of air, meaning that a higher volume of air must be let into the engine for a given fuel input. So with WAI, the throttle must be opened further for a given output, and this lowers the "pumping" work of pulling air past the throttle.

WAI is better than CAI for fuel efficiency...
Heck, this stuff is even supposed to be patented...
Hot-air intake system of an internal combustion engine - Patent 4365607

Why not to do it...
Quote:
The main disadvantage to all of these is the fact that they are drawing in hot air from inside the engine compartment. Intake air temperature is very important whenever performance is a concern. It is a general rule of thumb that a engine will loose one horsepower for every additional ten degrees that the intake air temperature is increased. The engine compartment of an automobile is a very hot place, with heat radiating off of the engine block and head, the exhaust pipe, and air passing through the radiator which is full of 180 degree water. it is no surprise that under hood temperatures can easily reach over 220 degrees. Even on hot summer days when it is 100 degrees, the potential intake air temperature with these hot air intake systems is 120 degrees over the temperature of the outside air. It is very easy to see that any performance gain from reducing restrictions of air flow is quickly lost from increased intake air temperature.

Performance will be worst when attempting to accelerate from a standing start, as engine compartment temperatures will be highest when the car is not moving, lowering only marginally with the air being blown through the radiator as the car is moving, because, remember, the radiator is full of 180 degree water and the job of the radiator is to transfer heat from that water to the air passing through the radiator.
....
Many people will vigorously defend hot air intake systems, claiming that they can feel a great deal of power improvement, but much of their claims can be attributed to the placebic affect of a louder intake sound. "It sounds louder, it must be making more power" is the theory, but actual testing tells a very different story, that these are the least effective way to improve engine performance.

From ISUPAGE; Performance Intake System Basics
So was this not done before? Sure it was. There has been a company around in Kolkata since at least the last 20 years - this one: SMG-HAI. Promises all the things that DorfKatel's Oxyplus does.

My take on this: I keep away.

Didn't you see the catchline? Dealers who want to market the products of this company have to deposit 15 lakhs with the company!!

This company does not even care about cheating the customers. It's out to cheat the dealers who are stupid enough to invest in this scheme/scam.

What a SCAM! What really angers me is that, in such a large market that's obsessed with fuel efficiency, they will find lots of gullible customers paying for the oxyplus rubbish.

Dorf Katel say they are publicly listed in Canada. That's just hogwash! And their web domain was only registered like 6 months back.

Not only do they cheat the end customer, but also entrepreneurs of their investment. Adding name to the thread title so that (hopefully) potential customers googling will find this thread.

Just called the number given on their website to pull out more info on the product and benefits. This dude picked up the phone and instead of providing details, went on to offer his dealership schemes like invest 4lac blah! Blah!. I cut him short and made it clear that i was an end user and i called to ask about the product and i wanted just that. He started saying this is a "Unique" system which our R&D Unit in Germany has developed, you will save fuel of atleast 30-90% and your engine will remain as good as new. After that i asked his about the pricing. He quoted Rs. 1200-2000 for 2 Wheelers, 8K - 14K for Cars and 26-30K+ for heavy vehicles. He said it is a bolt on kit which will be clamped to the exhaust and offered me a free Kit if i paid the dealership amount and promised to refund if was not satisfied with the product provided i return ir back to them. The details were quiet shaddy and i see a lot of people (read-noobs) falling for it. The same way they do in case of 2 wheelers with the red thingy on the spark plug connectors.

There are so many of these so-called fuel saving devices out there, it ain't funny any more.

Did anyone watch the Mythbusters episode (Discovery channel) on these fuel saving devices? Couple of them actually increased fuel consumption!!!

My take on all these devices? They are snake oil, I am intelligent and non-gullible, so I stay away.

Good entertainment value though.

@sarvodaya: thanks a lot for the info. Was in a terrible mood but reading the company's claims definitely lightened it

Was thinking the same thing. Hell, i'm getting an FE of 10, maybe i won't need any fuel at all if i strap this gizmo on!

On a more serious note, I won't be surprized if the company actually swindles a lot of new businesses out of some hard cash. There'll be many people yet who will know its a sham, but make it more believable & sell it off to unsuspecting buyers.

There really should be a central monitoring body to take care of such unscrupulous companies, does anyone know if & where this can be reported?

The SMG-HAI site:
Quote:

Highlighted the key points in bold. Now, doesn't this excerpt sound more thought-out & genuine?

What a joke! By looking at copied BMW symbol and spelling mistakes, this looks like another chinese company for me!

This is for more ROTFL. They refund the money as well

He meant, if you pay up the dealership money (5 lakhs), they give you a unit free - and then if you didn't like the product, you may return it for a refund of it's price (maybe even 26-30k).

@SS: Its a refund of the dealership money only. The unit will be given free for a trial and if not satisfied, on returning the product the money will be refunded (dealership fee). Hope that clears everything
