Natural gas can be used to fuel almost any kind of vehicle - motorcycles and three wheelers, cars, vans & pickups, lift trucks, buses, trucks. 

Equipment for NGV vehicles

The six main component parts fitted to the vehicle are:
a) The filler connection which incorporates a non return valve.
b) The NGV storage cylinder together with a cylinder valve which incorporates a fusible plug.
c) A first stage regulator to reduce the pressure from 20MPa to approximately 0.7MPa.
d) A vacuum operated NGV fuel lock-off valve which prevents the flow of NGV fuel when the engine stops.
e) A second stage regulator which further reduces the pressure.
f) An air/gas mixer that measures air flow and meters the flow of gas into the engine.

NGV fuel cylinders
The NGV fuel cylinder is a tested pressure vessel which is designed and constructed in accordance with strict Malaysian Standards. During manufacture it is subjected to controlled heat treatment. Therefore it is imperative that no welding, soldering, brazing or heating of the cylinder takes place after the manufacture of the vessel.
All cylinders must be securely and permanently affixed and must be capable of being filled in that position.
Some NGV fuel cylinders are constructed using fibreglass reinforced plastic (FRP) wrapped around the outside of the steel cylinder. This type of construction allows for a lighter NGV cylinder but it is important that the FRP layer is not damaged as this provides part of the cylinder’s strength.
All-steel cylinders and FRP reinforced steel cylinders must be inspected periodically. All-steel cylinders may continue to be used for as long as these inspections show that the cylinder remains sound, however FRP wrapped steel cylinders must be replaced after 15 years of use.

In the case of a converted vehicle, a CNG storage cylinder is usually installed in the trunk of the car. Apart from the loss of trunk space, the driver will notice little difference in the performance of the vehicle (though they will usually notice lower fuel costs). An OEM (production line) vehicle often has the CNG storage cylinder installed under a seat or elsewhere wihin the chassis to minimize or eliminate the loss of luggage space.

The availability of vehicles or conversion equipment varies greatly from country to country depending on local conditions. Here are some of the samples of car which have their equipments installed at our workshop.
