Hi Friends,
After going thru several write up’s in "Mouth Shut" I have finally installed CNG kit in my SX4 model 2007 considering the regular price hike of petrol.
The kit is Landi Renzo with advancer and Lambda with a 14 KG cylinder. Cost is around 25K with RC registration in Gurgaon.
I am writing this after driving almost 500 Km in CNG. The average was around 10Km/Lt(around Rs 65) now it is 15 Km/Kg(Rs 30/Kg) The pickup is not that bad atleast I can compromise when it comes to savings, driving in too congested area can become irritating as RPM suddenly falls when the engine is idle.(Less then 500 RMP) I don’t have any idea why so. You will also feel heavy while driving.
Engine performs good without AC. If the RPM is falling then switch off the AC and when its stable again switch it on, that’s what I do and it really works.
Earlier my weekend consumption was around Rs 500 not it’s less then Rs 150. Only thing where I need to compromise is in power.
Considering traffic in Delhi we hardly get chance to drive more then 60/70 Km/hour so that does not impacts daily office commuting until and unless you are in Chandigarh or Jaipur highway. Then we always have the option in driving in Petrol.
Only the limitation is tank capacity, I can fill about 10Kg if the pressure is too good so I need to refuel it again after around 150 Km’s.
You just need to make sure that your air filter is not chocked other wise you will have starting problems as well as pls try to drive atleast 2-3 Km’s in Petrol daily which will keep all sensors/nozzels clean and working.
Happy and safe driving!
Would like to add on one more thing that if you see that your RPM is falling which is a very common problem with SX4 as it has electronic throttle body then don’t panic just adjust the RPM knob on your CNG kit "clockwise" very slowly you will see that RPM is increasing. This is a weekly excercise which I did and my car is giving excellent performance. Now I am really happy!:)
I took my car for routine service to Pasco motors last week and got the throttle body cleaned, they charged me Rs 800 extra and now the RPM is totally stable and no more stalling issue. I cant even find any difference between petrol and CNG.
So what I have learnt is that whenever you install CNG pls change your air filter as well as get your throttle body cleaned if it is electronic to get proper performance.:)
November 15th 2011- I recently had been to Jaipur and with full tank of CNG my car ran 170 Km with AC, I am really impressed! 170 Km drive with CNG of Rs 330/- slight less then Rs 2/Km!
