What problem is this .

Hi guys

was driving smoothly yesterday that i felt that my jimny 1998 has lost power. I put it in "P" or "Park" mode and again started to drive yet the same condition. i was feeling that it might have been put in 3rd or 4th gear but when i put it in reverse gear, it moved with same power it usually has.
Drove it to the mechanic but didn't tell him about my opinion . he checked it and said that a "NET/Partition in chamber area which allows the gear oil to move around has gotten dirty. He took that "Net: out , cleaned it with Nasa rustonil solvent , which is used to clean the guns and refitted it . The jeep is surprisingly ok .
i am amazed to see all this ' . but i am skeptical that this solution may be tentative arrangement
have any of you experienced this ever'


These are the pictures of the engine my jimny 1998 model , japan assembled automatic jeep is running .
i shall be grateful if you tell me if it is G13bb or G16b

Hello, I see in the pictures you got installed CNG. This installation usually causes inconvenience and fault codes. check electronic added for CNG.

you have an eye of an eagle . i have installed CNG . yes, i have installed som electronic added for CNG as it is also visible in the pic but it seems it is not working properly.
shall be grateful if you plz suggest some electronic add for CNG

Hello Zain, Thanks, but not eagle eye. Here, in Argentina 2 millions of the cars run on CNG

:huh: CNG is the old acquaintance :huh:

Please reformulates the question "shall be grateful if you plz suggest some electronic add for CNG" I do not understand its scope, sorry.

Gustavo

i wanted to say that can you recommend or suggest any electronic device . i want to install that device so my car can run swiftly .

and does this problem happens with jimny running in your country on CNG also

Hello Zain

Now if I understand

There are two systems on the market to convert a vehicle to CNG: One for depression and other for pressure

In this system for depression, the CNG flow control to engine, is regulated by a fixed strangulation placed in the pipe connecting the pressure regulator and the mixer (the mixer is placed before throttle butterfly)
The fixed regulation is ONLY FOR CARBURETTOR ENGINES (not for injection engines)

Correct (carburettor)


INCORRECT - fixed regulation in a injection engines




In the injection engines the correct flow of CNG is controlled by variable valve controlled by a stepper motor in the main tube. (This system is called “closed loop”, since the position of the stepper motor that regulates the correct amount of CNG is provided by an electronic controller based on the lambda sensor reading)





OPTIMAL (for jimny) : The systems of the “positive pressure” (most moderns and efficient) is identical a fuel injection, four injectors of CNG provides a correct amount of gas in the cylinders.

These CNG injectors are driven by an original ECU of vehicle. A signal conditioner in necessary to adapt the electrical signal from the fuel injectors to CNG injectors.



if you need more information about CNG, let me know
