WHAT IS NGV?

Natural gas is a highly combustible odorless and colorless hydrocarbon gas largely composed of methane. It is produced in pressurized deposits located deep in the earth's crust, commonly located just above oil deposits. Natural gas is created in roughly the same manner as oil, by geologic processes that act upon organic matter over millions of years. High combustibility coupled with low emissions makes natural gas a highly valued resource. More economical than electricity, natural gas is primarily used for heating homes, cooking and running appliances such as water heaters and clothes dryers.

A Natural Gas Vehicle (NGV) is a vehicle which runs on natural gas, a fuel which burns much more cleanly than gasoline. Because many countries are seeking alternatives to gasoline as a fuel source, the use of NGVs is growing around the world, as the cars are energy efficient and very clean burning. Consumers in some countries can purchase NGVs, and existing cars can also be converted to use natural gas. In addition, many companies offer fleet vehicles which run on natural gas, allowing cities to convert their cars, buses, and trucks to natural gas.

HOW NGV WORK?

Natural gas is compressed and enters the vehicle through the natural gas fill valve (receptacle).
It flows into high-pressure cylinders located in or under the vehicle.
In a bi-fuel NGV, a fuel selector on the dashboard permits selection of natural gas or gasoline to act as the fuel for the vehicle. A dedicated NGV operates solely on natural gas.
When natural gas is needed by the engine, it leaves the cylinders and passes through the master manual shut-off valve.
The gas goes through the high-pressure fuel line and enters the engine compartment.
Gas enters the regulator, which reduces pressure from up to 3,600 psi to near atmospheric pressure.
The natural gas solenoid valve allows natural gas to pass from the regulator into the gas mixer or natural gas fuel injectors. (Or, it shuts off the natural gas when the engine is not running or when, in the case of a bi-fuel vehicle, gasoline is selected).
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. In a dedicated NGV, natural gas is injected into the engine's combustion chamber via specially designed natural gas fuel injectors.
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.

WHY CONVERT NGV?

Green fuel - Commonly referred to as the green fuel because of its lead and sulphur free character, CNG reduces harmful emissions. Being non-corrosive, it enhances the longevity of spark plugs. Due to the absence of any lead or benzene content in CNG, the lead fouling of spark plugs, and lead or benzene pollution are eliminated, which result in cleaner environment.

Increased life of engine - Another practical advantage observed is the increased life of lubricating oils, as CNG does not contaminate and dilute the crankcase oil, which result in cleaner engine and engine life span.

Safety - CNG is less likely to auto-ignite on hot surfaces, since it has a high auto-ignition temperature (540 degrees entigrade) and a narrow range (5%-15%) of inflammability. It means that if CNG concentration in the air is below 5% or above 15%, it will not burn. This high ignition temperature and limited flammability range makes accidental ignition or combustion very unlikely.

Low operational cost - The operational cost of vehicles running on CNG, as compared to those running on other fuels, is significantly low. At the prevailing price of fuel, operational cost of CNG vehicles is about 75% lower than petrol and diesel in Malaysia.
