Frequently Asked Questions
What is CNG?
Compressed Natural Gas (CNG) is a clean and efficient fuel derived from natural gas, primarily composed of methane. Natural gas is extracted from deep underground reservoirs and processed for use as an energy source (it is also commonly used as cooking gas).
When natural gas is compressed to a high pressure of approximately 200 bar (about 3000 psi) and stored in specially designed seamless steel cylinders, it is known as Compressed Natural Gas (CNG). This compression allows a large quantity of gas to be stored safely and used as an alternative automotive fuel.
Benefits of CNG Fuel
Safety
Lighter than Air
CNG is lighter than air and disperses quickly in case of leakage, preventing dangerous accumulation.
High Ignition Temperature
CNG has a higher ignition temperature than petrol, diesel, or LPG, reducing the risk of accidental or spontaneous combustion.
Safe Storage
CNG is stored at high pressure (200 bar) in specially designed cylinders, which prevent air entry and significantly reduce the risk of explosion.
Economy
Cost-Effective Fuel
CNG is more economical than petrol or diesel and offers better mileage, potentially reducing fuel expenses by up to 70–75%, depending on usage conditions.
Longer Engine Oil Life
Due to clean combustion, CNG does not contaminate engine oil, increasing oil life by up to three times.
Cleaner Spark Plugs
CNG does not produce carbon deposits or sediments, keeping spark plugs cleaner and extending their life up to three times.
Better Lubrication
Unlike petrol, CNG does not wash away lubricating oil from cylinder walls, ensuring better lubrication and longer engine life.
Reduced Emissions
CNG combustion produces significantly fewer harmful gases, no smoke, and is less corrosive than gasoline, thereby extending the life of the exhaust system and muffler.
High Octane Rating
CNG has a higher octane value than gasoline, enabling smoother engine operation, quieter performance, and improved startup.
Environmental Benefits
Clean Combustion
CNG contains no harmful additives and produces very low toxic emissions. Its homogeneous mixing with air ensures near-complete combustion, significantly reducing environmental pollution.
Eco-Friendly Fuel
CNG supports a cleaner and greener environment by lowering greenhouse gas emissions and contributing to sustainable energy use.
Maintenance Guidelines for CNG Vehicles
Proper maintenance ensures optimal performance and long engine life when using CNG.
Air Filter
Keep the air filter clean to ensure proper gas-air mixing, preventing higher fuel consumption and irregular engine operation.
Ignition System
Regularly inspect and maintain the ignition system. Replace worn or faulty components to ensure efficient performance on both petrol and CNG modes.
Cooling System
Maintain the radiator and water circulation system properly. Use coolant with anti-corrosive and anti-freezing properties to enhance engine life.
Starter & Battery
Ensure the starter motor and battery are in good condition for reliable vehicle operation.
Intake & Exhaust Valves
Maintain the correct valve clearance between the valves and camshaft for smooth engine performance.
Very Important Recommendations
- Always have CNG systems inspected and serviced at an authorized workshop. Replace damaged components only with genuine spare parts.
- After driving on CNG throughout the day, switch to petrol and drive 1–2 km before parking at night.
- In the morning, start the vehicle on petrol, drive 1–2 km, and then switch to CNG mode.
This practice helps maintain the fuel system and ensures long-term reliability of your vehicle.
