They are basically two type NGV systems currently being used in Malaysia. For common cars a Mixer System NGV are being installed and most imported are being fitter EFI Fuel Injection System.
Here we listed the basic of both NGV systems.
CNG –NGV Conversion On Carburetor
Type Engine for petrol vehicles. This type of conversion is commonly known as conventional CNG / NGV Conversion. Mixer system is compensate 5% to 15% power of the car, semi automatic means it need to press a button to change between modes from NG to petrol or vice versa when the NG is used up or otherwise.( bi-fuel system )

Mercedes A-Class F-Cell looks like any other Mercedes A-Class yet this really is a car for the next generation. The F-Cell is hydrogen powered meaning no harmful gasses are emitted when driving the vehicle.
The technology that drives this car consists of an electric motor, batteries and two hydrogen tanks. Mercedes have done away with the petrol engine and fuel tank.
Built as if it’s a proper production model this A-Class contains 10 years of development in Hydrogen technology at Mercedes. Mercedes hopes to have hydrogen-powered cars on general sale by 2015. Hydrogen technology still has some way to go with 60mph coming in at over 15 seconds as the electric motor producing only 87bhp.

Obviously on day to day basis NGV converted cars are becoming a normality in our roads. Before you start dumping RM 4000 ++ for any NGV system, lets have a closer look at the real benefits and drawbacks of NGV as a vehicle fuel.
Notes :
Compressed Natural Gas (CNG) is a substitute for gasoline (petrol), diesel, or propane fuel. It is considered to be a more environmentally “clean” alternative to those fuels and it is much safer than other motor fuels in the event of a fuel spill: natural gas is lighter than air, so it disperses quickly when leaked or spilled.
It is made by compressing natural gas (which is mainly composed of methane (CH4)),to less than 1% of its volume at standard atmospheric pressure. It is stored and distributed in hard containers, at a normal pressure of 200–220 bar (20–22 MPa), usually in cylindrical or spherical shapes .
Natural gas vehicle or NGV is a alternative fuel vehicle that uses compressed natural gas (CNG) or, less commonly, liquefied natural gas (LNG)) as a clean alternative to other automobile fuels.
Liquefied petroleum gas (also called LPG, LP Gas, or autogas) is a mixture of hydrocarbon gases used as a fuel in heating appliances and vehicles, and increasingly replacing chlorofluorocarbons as an aerosol propellant and a refrigerant to reduce damage to the ozone layer.
1. What is NGV
NGV or methane is the lightest hydrocarbon. It is often extracted from underground but not always associated with oil and coal deposits. Methane is a by-product of decomposing organic matter including the rotting of dead plants, garbage dumps as well livestock manure.

The government is likely to invest more on NGV stations since there is a sudden surge of interest from the public. Excerpt from BERNAMA:
Petronas had been directed by the government to have 200 stations ready for natural gas vehicles (NGVs) in a bid to encourage gas use in vehicles, the Dewan Rakyat was told Tuesday.
Minister of Domestic Trade and Consumer Affairs, Datuk Shahrir Abdul Samad, said currently there were 73 such stations operating and two more would be ready this month.
“Twenty-five NGV stations will be ready by the end of this year while 100 more will be ready in 2009,” Shahrir said .
Dr Che Rosli wanted to know the status of NGVs which used compressed natural gas (CNG) and liquefied natural gas (LNG) as their energy source and whether there was sufficient infrastructure to encourage consumers to switch from petroleum to CNG and LNG.
Shahrir said the gases were being used as an alternative in private vehicles and commercial and public transportation vehicles in the country, adding that the gases were also exported.
The infrastructure to be developed would support about 10,700 NGVs, he said.
Shahrir said many in the industrial sector used CNG as an energy source and it was piped directly to factories and independent power producers.
With 200 stations plan by 2009, CS think it is still cannot overcome the overall public needs of an alternative and yet cheap enough fuel stations through out Malaysia.
Malaysian motorists are seriously considering the option of converting to the NGV (Natural Gas Vehicle) system to save on fuel cost.
An NGV uses compressed natural gas (CNG) or, less commonly, liquefied natural gas (LNG) as a clean alternative to other automobile fuels.
In Malaysia, natural gas, which currently costs 63.5sen per litre, is widely used by taxi operators to cut down on running costs.
When Steven Sum, 47, converted his Pajero to the NGV system a few months ago, he noticed a slight reduction in the vehicle’s power. But that’s not been much of a bother considering the savings he is making in terms of fuel purchases.He has managed to cut down fuel costs by almost 80%. At current fuel prices, Sum says, the cost to run his vehicle is 50sen/per km whereas with natural gas it is only 9 sen/per km. It cost him RM8,800 to convert the engine, he says.“It warrants spending (conversion costs) but it is worth it in the long term. The investment can be recouped in a year,” says Sum who is now thinking of converting his wife’s car as well.
Thong says the technology is viable for petrol cars. For a normal passenger car, the cost of conversion can vary from RM3,500 to RM5,000 depending on make and the type of system installed, he says.“All petrol cars can be fitted with the system although you would need the right components for particular models,” he adds.
Thong claims that using NGV reduces fuel expenses by almost 75%, with certain cars able to get almost 90% on savings. He adds that natural gas is also better for engines and the environment because it burns cleaner compared to petrol or diesel.

Know your Car : NGV ( Natural Gas Vehicle)
Cylinder: Methane stored at high pressure up to 3,000psi
High Pressure Pipe: Sends methane from cylinder to regulator
Pressure regulator: Pumps cylinder gas to engine via intake manifold
Low Pressure Hose: Sends low pressure gas from regulator to mixer
Mixer: Mixes air and gas before they go into the combustion chamber
Anti-contaminant Electronic System (AES): The controller that processes data from various parts and regulates stepper motor actions
Stepper Motor: Controls how much gas enters the engine
