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 .

Auto Repair Shops

The Spanish fleet is one of the oldest in Europe: 35% of the 19 million passenger cars on our roads are over a decade old, and 10% over 20 years. Motorists spend an average of 433 per year on car maintenance, which have a workshop on average 2.4 times a year. And even though the vehicles are getting better, motorists spend 34% more visits to the workshop five years ago and come to them only a little less than before. Have increased work associated with vehicle air conditioning, electronics and compressors have decreased while more traditional tasks such as changing spark plugs, brake pads and exhaust pipes.

Another Spanish peculiarity is the atomization of the sector: nearly 52,000 shops operating various types (premium small) rather than in Germany and France combined. And it only takes the car to a garage official representative of your brand while it is under warranty: During its first year of life for almost 80% of cars seen only official repairers for its brand, but the proportion drops precipitously over time, staying in a bare 38% in the fourth year. Since 1986, the legislation requires repair and maintenance of vehicles to meet certain requirements, including the obligation to prepare a written estimate before repairs and to show the rates for labor.

CONSUMER Technical Eroski, posing as customers, recently visited 200 of these workshops in 13 cities (Madrid, Barcelona, Valencia, Sevilla, Malaga, Bilbao, A Coruña, Oviedo, Pamplona, Vitoria, San Sebastian, Murcia and Zaragoza), 78 of them were independent or traditional (not linked to any other label), 60 were official dealer workshops and the remaining 62 marks were fast mechanical or franchise.

Although the law requires them to do so, more than half of the 200 workshops studied exhibited no charges for labor and 35% refused to prepare a written estimate

It was found in all the information provided to the user (both verbally and displayed on posters or panels) and in compliance with the rule governing, among other things, exposure of plates and identification numbers, and information warranty repair and labor charges. 13 cars were used, all of medium or low range, one for each city, and asked in the workshops the price of a basic check (oil levels, windshield wipers and antifreeze, state and belt tension, condition of tires, pads and discs, dust and slacks, shock absorbers and exhaust line) unchanged liquids or replacement of parts or components, and also the cost of battery replacement. In all the workshops are asked for a written estimate.
However, the report's main conclusion is that often the information received by the customer in the workshops is insufficient and violates the rule to not have plate-mark on the outside (18% of the workshops), exhibit no charges for labor (55%) did not show the hours of the workshop (40%) and not reporting the existence of the book of complaints (62%), or the right to receive a written estimate (70%) or warranty of at least three months or 3,000 miles which have all repairs (64% of shops surveyed.)

Another observation: one in three shops refused to give a written estimate EROSKI CONSUMER technician (who introduced himself as another client), although they are by law obliged to do so and that they reiterated several times this requirement. Among the reasons adduced employees of the workshops were recorded more or less reasonable excuses ("is not in charge of preparing the budget," or "we have to do a deeper review of the vehicle), but others were just as unacceptable as do not usually written estimate, "" never asked us, "does not work the computer" or "I walk with a lot of work and I have time." But only 3% of the workshops that the workshops that made the written estimate charged for the preparation of that (the price was from 10 to 25 euros).
