I'm sorry, mistaken and explained wrong in my previous post about coolant being used in vaporizer

What is a Vaporizer ?? Is it a separate cooling unit for the GAS kit ??
Vaporizer uses the engine coolant to vaporize the LPG in liquid state to gas. Also it reduces the pressure.

I too was thinking that if the engine gets hot due to use of gas kit the thermostat will keep the radiator on for more time till engine cools.
Using gas kit will not affect the engine temperature (there will be effects, but negligible)

Mechanics say that with the thermostat the engine will get over heated.
What should we do ??? Install the thermostat again or not .
Fit the thermostat back and observe the engine temperature.

Hi for Cng fitment quality is more important than brand,any kit can be fitted to any vehicle.
If you want your RC endorsed with CNG fitment then you will have to check as which make of car is approved with which brand of CNG. For CNG there is no need for water connection except when temp is below O degrees for lpg yes water connection is must as LPG is very cold.Even on LPG there is no need to remove thermostat valve. In any fitment LPG or CNG try to start your vehicle on petrol till it reaches its normal temp (temp needle at half ) before switching it to gas,this practice will keep your injectors & manifold clean & running,when fitted with Gas always keep your petrol tank with 1/4th fuel to avoid damage to fuel pump which later on can result in running your car n rich petrol mode.It is also advisable to cut fuel pump wire & planting a relay in circuit to fully disconnect fuel pump while driving on GAS

CNG/LPG experiences with kits & accessories

Hi
Nowadays maximum people are running their vehicles on LPG / CNG
I would like to gather all experiences good or bad with GAS fitment.
I personally feel there are lots of mechanics fitting kits in cars but their ability to diagnose a problem or adding any new accessory to the conversion is very limited.
Please share

Clarification about AUTO LPG related

Hi,

I have the following two clarifications.

  • Is it possible to fit LPG kit in nano?
  • I have Spark LPG now. Assume in near future CNG is made available in chennai shall i convert the kit to use CNG instead of Auto LPG.
Thanks

for power there are two ways either increase gas flow or change it to sequential ( 0% loss) might cost you around 20k in exchange of current kit
