Upgrading your gasoline powered vehicle
Upgrading your gasoline powered vehicle to use CNG involves installing a conversion kit. The kit consists of components that store and deliver natural gas to the engine. The kit can easily be removed and the vehicle returned to operation solely on gasoline.
To convert your vehicle to use CNG, it is fitted with a conversion kit which consists of:
• Components that store and deliver the CNG to the engine;
• A refueling port;
• A dashboard mounted gauge to indicate how much fuel is available; and
• A switch that allows the engine to operate on gasoline or CNG.
The conversion to a Natural Gas Vehicle (NGV) retains the use of gasoline, and the NGV is considered bi-fuel since you can change to either fuel with the flip of a switch even while driving.
Also, the kit can easily be removed and the car returned to its previous condition.
Is my vehicle’s performance affected?
CNG has a higher octane rating than even premium gasoline and produces smoother, quieter performance. The components in a modern conversion kit also minimize power loss.
How long does conversion take?
Depending on the complexity, upgrading your vehicle to a Natural Gas Vehicle (NGV) can take one to two days.
There are two types of NGVs:
• Dual fuel NGVs use Diesel and CNG simultaneously. They have standard diesel engines in which CNG is used to displace up to 85% of the diesel, depending on the operating conditions of the vehicle.
• Bi-fuel NGVs have standard gasoline engines which can use either CNG or gasoline. The driver can select which fuel to burn simply by flipping a switch on the dashboard.
Locally over 4,000 vehicles have been converted to NGVs to date.
Internationally there are over 22 million NGVs in operation and over 18,000 refuelling stations in 84 different countries.
How far will a fill take me?
CNG is sold by the Litre Gasoline Equivalent (LGE) which means that a litre of CNG will have the same energy and will take you as far as a litre of gasoline.
If your vehicle gets 10 kms from a litre of gasoline, it will also get 10 kms from a litre of CNG. So if your fill was 15 LGEs of CNG, you can expect to get 150 kms (10×15) before needing to refuel. A 70 litre cylinder contains about 17 LGEs of CNG.
The local CNG market currently consists of a network of eight refueling stations and about 3,000 vehicles running on CNG.
