this thread is for CNG users to share their experiences and for non CNG users to get a sense of the pros and cons of the system.
As a recent CNG user, i must say that i am very impressed with the CNG kit in my car. With a 2000 cc engine, it is $14 dollars to fill the cng tank, which gives me enough power to do general driving. When i need more power, i simply flick the switch, and the engine gives full power with the premium gas i use.
It is an excellent mix of power and economy.
They are adding more CNG stations, which should make the fill up process more convenient. On the East West corridor, there are CNG facilities in the new Beetham Gas Station, the Gas Station by Maritime Plaza, by the Kay Donna Gas Station and also at Automotive Components ltd in Arima. Before this experience i thought that CNG tank takes a long while to fill, however it is very quick to fill, just as quick or quicker than filling up a normal tank of gasoline. With one tank of CNG, i can get 100 miles.
It would be good to get a sense of how many CNG users are out there, though of course many of them would not be on this forum. I am planning on writing to PEake's Gas Station in Cocorite to lobby them to install a CNG facility for the users in the West.
I am unsure of how compatible CNG kits are with newer cars with higher compression engines, but in this belt tightening era, a CNG kit can be a good investment.
It is also said that CNG works better with manual cars.
Nice mix of power and economy
Easy switch between gasoline and CNG
Much cleaner gas, with a higher octane rating (130),
Loss of some trunk space
Approx 10% less power on CNG
Restriction of about 60% of airtake which is necessary for the CNG kit to work properly. This can have a slight impact on the normal gasoline performance.
Regarding safety of the CNG system:
"In todayâ€™s world there are constant advances in all aspects that concern security in case of automobile accidents; in gasoline vehicles the fuel is transported in thin sheet metal tanks that are very fragile when impacted and can explode. CNG is stored in steel cylinders with 6 to 8 mm thick walls; this literally makes it the most resistant component of the vehicle. The steel fuel pipes are also more resistant than the gasoline ones; even if there were to be an accidental breakage or leak, instead of the dangerous gasoline spill on the ground underneath the vehicle, the very light CNG will rise rapidly and dissipate into the air"
