Use your imagination for the rest of the setup.

sir pwede mangayo ug pics lang sa setup bisag dili sa imo para try lang kung pwede ba siya buhaton sa akong car karon. ask lang pud ko. unsa may source sa cold ug hot air? unsaon pagsulod ani nila didto sa makina? not so familiar with cars and engine, pero sa akong nahibaw-an kay isa ra man ka intake tube ang naa gud. or mao na ba kaha ni nga setup? -- ang air intake tube gibutang palayo sa makina nya naa lang siya murag gamay nga tube nga giconnect ug rubber hose didto sa breather sa makina. sa akong pagtuo kay ang hangin gikan sa makina agi sa breather kay ang hot air nya ang masuyop sa air filter kay ang cold air.

Combustion is a ratio of air and fuel,the ratio depends sa engine design(gas/engine). Air filter is your only defense against solid particles getting inside your engine but it lessens performance, thats the tradeoff, dirty air filter(clogged) is less air intake add it with fuel=unbalanced combustion/bonol, problem sa bonol,the more ta step sa accelerator,the more kas ug fuel,ideal air intake is not just air pressure but by density, cold air is more dense that why you use nitro for boost,problem with our cars design is its intake manifold is near the engine/ its hot and air is expanded.most diesel power plants we design has big fuel saving by just periodic air cleaning and preventive maint sched, less fuel rack opening but still has same exhaust temp and combustion pressure. Race cars use tuned design bell intake manifolds (murag saxophone) that utilizes the venturi design,example inyo water hose pag pislit tomoy kusog agas,other uses supercharger,its just like an air pump that utilizes the exhaust pressure to rotate the common shaft blower(separate chamber)to build pressure for intake even at low rpm, testing open inyo intake if see difference, i had made countless revision on my 1999 hilux intake and now it runs at 10-12 km per liter, try double venturi stage,mine is triple. Other cars uses exhaust manifold air heater for the intake, its a thermostatically controlled valve that allows exhuast heat to be applied to the mixture when the engine is cold only, it fully closes when the engine reaches its normal operating temperatures.either l-type/straight or v-type. Thats why sa double muffler ninyo, us ra aso gawas sa usa ka muffler kung bugnaw makina.

I plan to buy a cold air intake soon. Theoretically, it is much more fuel efficient. From thermodynamics, "Q=mC(Final Temp-Initial Temp)" is the equation for heat. Q being heat, m is mass, and C is specific heat. Heat is the "combustion force" that pushes the cylinders. If the initial temp is lower than what it normally should be, then final temp minus initial temp would be equal to a larger number than what it should be. This makes it a larger multiplier.

Example:
Lets make the m(mass)=1 and the C(specific heat)=1.

Normal intake (initial temp=50)
Q=mC(Final Temp-Initial Temp)
Q=1x1x(100-50)
Q=50

Cold Air intake (initial temp=40)
Q=mC(Final Temp-Initial Temp)
Q=1x1x(100-40)
Q=60

Since the second one has a larger heat value, it has a stronger "combustion force" with the same amount of mass(fuel air mixture). Surely you would waste more gas if u get tempted to really floor the throttle body though. hehehe

Ang combination sa hot air intake ug cold air intake ang nindot nga setup. Car manufacturers already knew about it several years ago. Panagsa lang ka kakita (swerte nalang gyud kung kakita ka) ug ing-ana nga setup on cars nga para sa country nato ibaligya. Adto panan-aw sa surplasan ug combination sa cold ug hot air setup.

Ang tuyo sa hot air, pang expand/bungkag sa fuel aron mas maayo ang vaporization. Ang tuyo sa cool air, mas daghan ug content ug nindot isagol sa bungkag nga fuel. Daghang pamaagi ang pag implement ani nga setup, the only limit is only your imagination.

We used to ha have a Ford Laser before and it has this hot air intake. This is actually designed for cars to run on areas with winter season. It has a "winter" and "summer" lever at the mouth of the flannel of the carb air intake filter case. The Japan spec engine is the same engine use here by Ford Laser. Newer EFI engine now doesnt have this since its already a computer controlled by its ECU and sensors. It gives enough fuel at a preset ratio.

Installing a after market air filters on EFI cars says it can "breath more air" or "it can suck more air", but put this in mind, The perfect ratio of Air and Fuel is constant at a certain RPM. In short "Fuel is directly proportional to Air". In other words, "MORE AIR needs MORE FUEL"! If you increase the air and NOT increasing the Fuel, it will result to LEAN BURN. So if the K&N can give more air then it needs more fuel to attain the Fuel to Air ratio. The engine can determine how much air goes in the combustion chamber thru its sensors and therefore adjust the amount of fuel to be injected to attain the preset Air-Fuel ratio.

Based on facts (on EFI engines), after market Air filters which gives you more air, will not save you fuel. but it will increase its power.

nice bai, i couldnt say it any better.. matud pa sa ako kauban sa manila, kung dli ka mag resing resing nanu mag taud man ka after market accessories, like high tension wire, CAI, change ug plugs, IHE. kibaw ba mo nga ang mga auto nga pang lumba daku ug kaun ug gasolina? kay the faster you go the more gas your car eats up.. so kung dli mo mulumba stay stock coz what you have under your hood is the next best thing in terms of saving fuel...

just my 2 cents..

[Kyukies]

it all depends on your driving habit..kalas kay mag cge man kag banat kay malingaw ka mas gaan xa dad.on..pero economiya rna kung mag normal driving lang jud ka..=)

sakto jud ka!
