CNG
Compressed Natural Gas (CNG) is a fuel obtained by compressing a natural gas to less than its 1 per cent volume at standard atmospheric pressure volume or 3600PSIA. It is use as an alternative automotive fuel with compressed natural conversion kit or compressed natural gas engine.
PHYSICAL PROPERTIES OF COMPRESSED NATURAL GAS
1. It is colourless and odourless.
2. It is clean and has a clean burning.
3. It has low carbon monoxide emission.
4. It has no particulate matter emission.
5. For safety reasons odorant mercaptan is added so that a leak can be detected.
DIFFERENCE BETWEEN CNG AND LNG
Compressed natural gas is a compressed natural gas stored in cylinders at high pressure while LNG is a liquid form of natural gas at a low temperature …show more content…
Ram (2005) stated the advantages of compressed natural gas over other fuels as follows:
1. CNG is a lightweight gas with a high ignition temperature and at normal temperature and pressure rapidly disperse into atmosphere.
2. CNG has high octane number of 130, therefore, it don’t need additives or anti-knock agents.
3. CNG has the lowest pollutants emission as compare to other fuels.
4. PMS has a problem of cold starting due to the fact that it has to vaporize before starting while CNG has better cold starting characteristics.
5. CNG engines have longer life span than other engines.
6. Using CNG gives longer time interval for engine oil replacement as compare to other engines.
DIS ADVANTAGE OF CNG
The major disadvantages of compressed natural gas are:
1. Loss of space due to storage cylinders and they add …show more content…
(a) Dedicated Natural Gas Engines: These are engines designed to work only on compressed natural gas and gives less emission as it has a high octane number (Muhammad and others, 2015).
(b) Bio-fuel Retrofitted Gasoline Engines: These vehicles engine can run either on compressed natural gas or gasoline. The driver normally selects the fuel he wants to use. Most of the gasoline engines can be converted to use compressed natural gas (Chris, 2014).
(c) Dual-fuel Vehicle Engines: These are engines vehicles that can either use diesel or compressed natural gas (Chris, 2014).
