` NGV stands for 'Natural Gas For Vehicles'.

`

It is equivalent to natural gas supplied to powerstations, industries, commercial establishment

and households.

` NGV is an environmentally friendly fuel and has

been proven to be lighter than air.

` It is specially developed to provide economic

value to users without compromising on quality.

1. Natural gas is compressed and enters the vehicle through the natural gas fill

valve .

2. It flows into high-pressure cylinders located in or under the vehicle.

3. In a bi-fuel NGV, a fuel selector on the dash permits selection of natural gas or

gasoline.

4. When natural gas is needed by the engine, it leaves the cylinders and passes

through the master manual shut-off valve.

5. The gas goes through the high-pressure fuel line and enters the engine

compartment.

6. Gas enters the regulator, which reduces pressure from up to 3,600 psi to near

atmospheric pressure.

7. The natural gas solenoid valve allows natural gas to pass from the regulatorinto the gas mixer or natural gas fuel injectors.

8. In a bi-fuel NGV, natural gas mixed with air flows down through the gasoline

carburetor or fuel injection system and enters the engine's combustion

chambers.

9. In a bi-fuel NGV, when the driver selects gasoline, the conventional gasoline

system is activated and the natural gas system is automatically shut off.

The bar graph show that many of respondents are very impressed and tension

with the increasing fuel price,

while the others level of opinion such as Moderate and cool with Not affected

at all have a very low number of respondents.

This result proves that Malaysian needs another alternatives fuel source that is

much cheaper such as Natural Gas Vehicles (NGV).

Based on the survey, we can see that male have an instinct to change their engine system

from based on oil to alternative sources,

while the most of the female respondents are classified in the not sure yet,

meaning they are not ready to change to alternative sources,

such as Natural Gas Vehicles (NGV).

Based on the survey, we can see that most of the female respondents have known

about the Natural Gas Vehicles (NGV),

while most of the male respondents did not know about the Natural Gas Vehicles (NGV).

This is a shock result, as usually male have high interest about the car and their systems

including the fuel, however his bar graph show the opposite characteristic.

Based on the survey, we can see that most of the male respondents have decide to not

convert their engine based system into Natural Gas Vehicles (NGV),

while most of the female respondents still did not sure yet about the

Natural Gas Vehicles (NGV). This is an expected result, as the cost to convert the

engine system to Natural Gas Vehicles (NGV) is very high.
