Gas saving device

[altec]

Ano daw nangyari pagkatapos niya kinabit sa expedition niya?

Years back, over dinner, we were talking about the expedition's fuel economy. Supposedly 2-3 km/liter lang strictly city driving, walang highway. Then one of my friend said that he gets at least 4 even 5 km/liter. What!! Sabi ng iba. Sagot niya, it all depends on the driving habits. Then tumayo siya, kasi kukuha ng pagkain sa buffet table. Sumagot naman ang asawa niya. Kaya naman 5 km/liter, maski tricycle, inoovertake daw sila! Yes, mga tsikoteers, yan ang sekreto para makatipid, di na kailangan ng mga modification. Pweh, kung ganun, naglakad na lang sana.

By the way, binenta na ng kaibigan ko ang expedition. Di rin tumagal sa kanya.

Naging matipid daw sa gas after lagyan. Personally, we would not put one on our Expy.

Driving style lang yan talaga. My dad gets 5-7 km/L on the city cycle with our 4.6 Expy. Basta dapat magaan lang ang paa. Wala namang karera, eh.

I agree with those who say that driving habits can drastically alter fuel consumption. With this in mind, a vacuum gauge that do not cost much is the best indicator for real time fuel consumption, albeit indirectly.

The vacuum gauge is connected to monitor vacuum pressure at the intake manifold. As any competent engine mechanic knows, vacuum drops when the throttle is opened and vacuum increases when the throttle is closed (as in during idle). Hence if one installs a vacuum gauge and drive in such a way as to keep the vacuum level at fairly higher value most of the time, then fuel consumption will be lowest.

Try it, and you will notice that vacuum can be maintained at higher values (lower fuel consumption) when you are easy on the gas pedal. Somebody once said that the most economical driving is to imagine that there is an egg between your foot and the pedal and drive without breaking the egg. This can be proven true with a vacuum gauge. With Manila traffic, there is no point being hard on the pedal. As you increase speed on the highway, one will notice that is becomes difficult to maintain higher vacuum, consistent with the fact that high speed requires more fuel.

So install a vacuum gauge, take care of that egg, and save fuel ! :D

aprub !!!

Our old Datsun 180B had a vacum gauge installed. So para dun pala yun. hehehe.

[ian_rex]

minsan talaga, walang logic ang tao e.

[FrankDrebin]

Well, sabi nga ng erpats ko kung mag-e-Expy ka dapat huwag kang mag-rereklamo sa consumo ng gasolina. In the first place alam mo ng malakas sa gas tapos nagtitipid ka.

[ian_rex]

well, expected na talaga sa expedition ang malakas sa gas. ang laki ng makina nun e. imagine, 3X ng size ng makina ng LXi ko? :D tapos matic pa.

[the_wildthing]

Maglalagay nga akong itlog sa gas pedal ko mamaya. Wala akong vacuum gauge e. Hehe.

And agree ako sa tatay ni FrankDrebin.

[OTEP]

Magastos lang naman yung Expy if you use its at full power. Around town, sobrang relaxed ng makina.

I drove Expeds before and even with a light foot, it still consumes nearly twice as much fuel as a 1.6-liter car. This big SUV is a born guzzler no matter what.

Going back to the topic, there's both positive and negative feedback on this KHAOS thingie. In other sites/forums I visited, some people said this device actually improved their cars' performance. So far, only one person has said KHAOS slowed down his car.

We are still in the midst of confusion here.

[blugsr98]

just to share my experience so far with KHAOS...
so far, their claim on the gas savings is really effective. i really do save around 25% on my consumption upon installation.
8-9km/l without khaos to 10.21-13.27km/l with khaos.
i think the offer they had on the 'money back guarantee' is something we could look into. they also guarantee extended lifespan of the engine.
in my case, don't realy know much on tech side of the engine so i just based my car performance on the fuel consumption. i do consider this as good investment.
again, it is still your choice to try and not to try the product. thanks!

We really need independent testing for this.

under what testing conditions are these numbers from? I could always claim my car does 10-12km/L under normal driving conditions (and it can)... and thats without khaos. My engine mod is a K&N cone filter.

i think the offer they had on the 'money back guarantee' is something we could look into.

...maybe you are the one who should look into it... read on and find out why.

they also guarantee extended lifespan of the engine.

Who and by what principle of their device's function does that "extends" the lifespan of the engine? Some jeepney driver/mechanic or what?

These are some interesting effects of a lean burn in a standard engine:

-High Temperature - this causes higher than normal operating temperatures. This can lead of your engine overheating. This WILL also result in your motor oil to degrade quicker than it normally would. This will lead to MORE oil changes ... not less.

-Pre-Ignition - This occurs when a point within the combustion chamber becomes so hot that it becomes a source of ignition and causes the fuel to ignite before the spark plug fires. This, in turn, may contribute to or cause a detonation problem. Instead of the fuel igniting at the right instant to give the crankshaft a smooth kick in the right direction, the fuel ignites prematurely (early) causing a momentarily backlash as the piston tries to turn the crank in the wrong direction. This can be very damaging because of the stresses it creates. It can also localize heat to such an extent that it can partially melt or burn a hole through the top of a piston!

-Detonation - (also called "spark knock") is an erratic form of combustion that can cause head gasket failure as well as other engine damage. Detonation occurs when excessive heat and pressure in the combustion chamber cause the air/fuel mixture to autoignite. This produces multiple flame fronts within the combustion chamber instead of a single flame kernel. When these multiple flames collide, they do so with explosive force that produces a sudden rise in cylinder pressure accompanied by a sharp metallic pinging or knocking noise. The hammer-like shock waves created by detonation subject the head gasket, piston, rings, spark plug and rod bearings to severe overloading.

in my case, don't realy know much on tech side of the engine so i just based my car performance on the fuel consumption.

maybe its time to get a third party expert opinion? You did say you are NOT knowledgable on the tech side of engines.

... i do consider this as good investment.
again, it is still your choice to try and not to try the product. thanks!

I hope you have considered that money back offer they are offering or that you are saving up on a replacement engine when the one you have now starts to show premature internal failure.

Sigh... as if that will ever happen... Give me just ONE day with an equipped car and a garage... we can settle this quickly.

Now I know why the Philippines is not prospering....it's because of the crabs lurking around.

You prosper I will pull you down...hehehhe

or is it because of all the racketeers, swindlers, cheats, con artists, and impostors out there?

robbing people of their hard earned money. think of those pyramid schemes that has duped thousands of people.

if it is too good to be true, then it is.

[blugsr98]

ghosthunter, so far here's what we got from the dealer. regarding lean-rich mixture...

"at minimal vacuum (2inHg) the mixture po is always correct at any state of your engine, be it idle or high speed or anywhere in between. that means its neither rich nor lean. lagi lang pong tama as shown during actual installation kasi the 2 inHg is maintained no matter how high/low the rev speed is.

Look at it the other way, (without the device) you have a high reading of 17-21 inHg at idle speed and varies from 17 - 35 inHg (35 inHg occurs at engine breaking at high speeds) depending on the state of your engine. Meaning at any instance of idle state, you have very, very, very rich mixture! "

i hope you or other experts here could enlighten me on this one. coz i really don't know if the 2inHg is really a good figure.
i just saw the actual demo when they measured the vacuum reading on my car before (17.5inHg) and after(2inHg) the installation.

thanks for the help...
