PETROL TO CNG/LPG SAFETY SWITCH
CUM LEVEL INDICATOR FOR AUTOMOBILES
These
switches are used in cars having CNG/LPG kits where a
person can change over to petrol in case gas is over,
using the switch. Unlike other switches available in the
local market this switch can automatically monitor for
safety factors and if required can trip the system.
How it oprates:
This switch has 3 position ie.
1.Petrol - 2.Off
- 3.CNG/LPG
1. At petrol it can be oprated
on petrol.
2. Can't oprate no fuel going
to the Carburetor
3. It oprates on LPG/CNG.
If the car is on LPG/CNG while the ignition if the car
is on it will give gas for 3-4 seconds (adjustable) and
after that only if the car engine is on it will supply
fuel else it will trip the flow of fuel to avoid leakages
and wastage of fuel. But as soon as the car engine starts
it automatically resets its tripped supply. It can also
have monitoring of gas left in the cylinder.
