With higher petrol price skrg ni...ada la terlintas kat hati ni to look for solution or alternative...one of them is installing NGV cam gambar kat atas tu ikhsan http://ngv.net.my/...however, of course many issues la kan..cost benefit analysis..tapi kat blog ni http://myngv.blogspot.com ada some explanation on the issues...as follows
Misconception #1: How Safe Is Natural Gas?
* Natural gas is very safe and it is lighter than air.
* In the event of an accident, natural gas simply dissipates into the air instead of forming a dangerous flammable pool on the ground.
* Natural gas is less explosive and safer than petrol because it's ignition temperature is higher (630°C) compared to petrol (450°C).
Misconception #2: How Durable and Strong Is CNG Cylinder?
* CNG cylinder can last up to 20 years.
* It is stronger and hardier than petrol tanks.
* They are built to withstand extremely high pressure and are tested at 4,500 psi or 30 bar (less hazardous in case of a collision).
Misconception #3: It's Very Bulky & Heavy/Takes Up Too Much Trunk Space
* The CNG cylinder takes up to 1/3 of the trunk space only.
* On average, a 70 liter Fiber-Composite (Type 2) cylinder weights 53kg only.
Misconception #4: Power Loss
* There is only minimal power loss of between 5 – 10% on the power of your car.
Misconception #5: Inconvenient/Limited NGV stations
* There are currently more than 70 Petronas NGV refilling stations in the whole of Malaysia.
* Petronas has committed to have a network of at least 200 NGV refilling stations by end of 2008.
Misconception #6: Long Queues
* It takes an average of 90 seconds for each car to be refilled with Natural Gas.
* Taxis usually queue up to refill their cars in the morning, afternoon or evenings when they change or start shifts. At other times, there are not many cars queuing up at the NGV refilling stations.
Types of CNG-NGV Cylinders
Basically, there are 4 types of CNG-NGV cylinders.
In Malaysia, Type 1 cylinders are commonly used. Recently, a few NGV installers started installing Type 2 cylinders for their customers.
What are the differences between the cylinders?
Type 1 Cylinder
* All metal (aluminium or steel)
* It is heavy but cheap
Type 2 Cylinder
* Metal liner reinforced by composite wrap (glass or carbon fiber) around the middle (hoop wrapped)
* Less heavy but more costly
Type 3 Cylinder
* Metal liner reinforced by composite wrap around entire tank (full wrapped)
* Light weight but expensive
Type 4 Cylinder
* Plastic gas-tight liner reinforced by composite wrap around entire tank (full wrapped)
* Light weight but very expensive
finally, nak install tak nak, nak tak nak, poning den
