Considerations Before Making the Vehicle to be used with GNC

The various components of CNG equipment are:

1. Gearbox : He is responsible for reducing the pressure sends the tube and keep it constant while injecting the CNG engine, while the proportion of the dosing .. Good brands are Oyrsa , BRC, Tomasetto Achille ( Gear List ). Some have record low and medium , others just average. registration recommended having low to medium because it is easier to regulate. Ojo also got the record high gas hose before the mixer, in total are three settings (high, medium and low).

bypassing is heating up the heater hoses , having also other models with electric heating is not recommended. To maintain stability installation must be made longitudinally to the body of the car . Your installation must allow access to other systems in a normal car . Must be able to deliver the gas flow that the engine needs . The case of the Corsa is not problematic , if it is, for example, a 3.0 engine Falcon

2. Cylinders: They are storing CNG, are placed in the trunk or place of loading the vehicle. You have different brands , one of the most recognized is inflexible. Most people recommend you install the largest capacity that supports your trunk . Place a large tube involves possibly strengthening spirals and springs , put a smaller tube avoids this problem but you need to carry gas more often. In my particular case I had a tube in the Pointer 60 and I had to reinforce everything , plus the loss of place in the trunk. If I had to reinstall would install a smaller pipe trunk and let me not have to carry so much dead weight. Obviously this is for use in town, if mainly had to use the car on the road then opt for the large tube . That is user selectable .

3. Electronics: Undoubtedly THE CHIP NO . I will explain why:

In the case of most cars chip installation includes: Remove the ECU, opening the ECU, desolder the original chip , place a socket , place a chip bi-fuel ( with the program supposedly our naphtha + the addition of program GNC ). This involves some risk because the whole process is manual , or a bad weld or deny ECU goodbye forever. Another potential problem: Who knows if the program that put gasoline is the same as the one we had ? Raise the copy we have and what general or have a copy ? Other: Who knows what that is recorded in the program for CNG ? The normal is that in a carbureted car will give varying degrees of progress for others to walk well on CNG and then walk listening like pistons in gasoline . Who says you do not apply this concept to the curves of CNG in the chip? .

That's why I like emulators, and how one chooses to emulate and naphtha in the car is original. Obviously chip installers prefer to install them because they find it much easier to walk placing emulators.

Emulators are basically : Injector ( lie to the ECU saying they are on when in fact they are off), lambda probe ( lie to the ECU on the sequential reading of the probe to think that all is well ). usually also installed a variable speed , which is sometimes not necessary and sometimes if it depends on each case. Last if you put it later when you leave to facilitate installation in 0 º of advance and ready.

NO A LOS COMBOS happy or boxes , these are the three in a single box. If you break one you have to change all and I heard good results. In my case I had but in the Pointer chip is placed in an additional slot for which the ECU is not touched at all so if you wanted to take was original.

4. Cot: supports the tube is attached to the body. Fundamental it is approved , this means that you must have a stamp ENARGAS. Fundamental to let you remove the spare tire without any intrigue ( seats down and remove from the carrier, etc, etc). Fundamental issue of the anchors as befits the body but everything is beginning to crack . For the Corsa I think has to be lifted by the aid .

5. Miscellaneous: The water faucets one at the exit of the tube plus one in the engine compartment . If the filling or in the engine compartment . If you want to add a mouth load than under the line of the bumper because it is not possible , do not make a hole in the body because it is wrong. Try to install that extra mouth next to the petrol tank , the place is small but I think Molerpa have it there. Last if nobody wants to do this work because it is really difficult half , what I would do is install a second load opening in the trunk. Why? because I think that the hinges of the trunk are more ready to open and close more often than the hood.

6. Documentation: Invoice Form Assembly, Wafer stuck in windshield, Yellow Card in your name and roles in specifying the warranty periods. All this SI or SI, some things do not usually deliver .

7. Key switch: Most are named F1 ( I had that ) and Diel. In the case of a self-injection works with gasoline to CNG pass automatically. In all regulating the rpm to which you want to pass fuel . Some work with the pass others in acceleration and deceleration. I like to set the rpm at about 2000 rpm and deceleration. In this way I could walk out a touch to gasoline slowly until the engine warm up and then threw a long pass changes the 2000 rpm and when hooked the following change to the car was in GNC. In the present work are on acceleration and you have to make the change but stopped because the jerk paste when you accelerate. The optimum amount of LEDs is five to go , seeing that you have loaded and all you need to make a reservation. Some are automatically to gasoline when you run out of gas. Fundamental allow you emergency direct starting to CNG, but this is not always advisable to use it well . Put them in a place where you can see it easy and simple actions of the select button naphtha or LPG but almost never touches it.

8. Installation: Do things properly, soldering the wires and use heat-shrinkable , to be careful where pipes pass , etc, etc . This is like when you take the car to install an alarm, have to be lengthy .

9. Mixer: This issue is divisive ... In my case I never had the ProgID in my car so I go by comments.

The mixer 's function is inserted into the air through CNG comes from the gearbox, so the fall air mixed CNG engine. normal mixers have a peak which is the injected CNG (we call curtain pipe crushed) which added to the structure of the mixer itself cause a restriction in the flow of air admission. This will be a greater or lesser extent according to how well it is designed the piece.

If the pipe Prog disappears and the injection is bordering on the inner wall of the structure of the mixer so that the restriction goes away.

Differences in gait to CNG ? There may be many or none depending on how gourd is the mixer is not Prog.

Differences in walking to gas? Many , as restrictions are removed . In my case, the Pointer was the famous curtain pipe crushed. A CNG walked tolerably well , it lacked a bit of chop until it regulated Molerpa. There he became an airplane, but gasoline was a total slug . I always wanted to test it out but eventually I sold it so I could not test the theory.

Fundamentally, that do not cut any hoses to install , I have seen many cases of hoses $ $ cut with a knife to put a mixer and then to solve the problems of malfunction had to replace it.

More or less here you have an idea of what to evaluate. Recommend a place no one else will do, that is something half complicated. What if I can say is that much ask and escapes to tell you "hey dad the same thing " as this is a serious Cacho .
