CNG Cylinder Testing: in india CNG (Compressed Natural Gas) cars have become increasingly popular due to their excellent mileage and low running costs. However, compared to petrol or diesel cars, vehicles equipped with CNG kits require extra vigilance and regular maintenance. A little carelessness can not only damage your car but can also cause a serious accident like fire. Know the 5 big mistakes that CNG car owners should avoid.
1. Installing non-standardized CNG kit
Many people, in order to save money, install local or unauthorized CNG kits in their petrol cars.
- Danger: Substandard parts, loose wiring and incorrect installation may cause fire due to gas leakage, short circuit and friction.
- Right way: Always buy a company-fitted CNG car or get a standard and approved kit from a government-authorized workshop.
2. Ignoring wiring and gas leakage
Old wiring, cracks in rubber pipes or minor damage to a downed gas line are often overlooked.
- Danger: CNG gas is lighter than air and expands rapidly. Even a small spark can cause a fire if gas accumulates in the cabin or bonnet.
- Correct method: As soon as you smell CNG, stop the car in an open space, switch off the engine and get it checked by an expert immediately. It is necessary to check leakage and wiring every 6 months.
3. Postponement of servicing and fitness certificate
Many vehicle owners postpone regular service of CNG kit and cylinder testing.
- Danger: Valve seals, regulators, and pipelines weaken over time. Without testing, an old cylinder may burst under high pressure.
- Right way: Get fitness certificate done after servicing every 10-15 thousand kilometers and hydro test of cylinder every 3 years.
4. Overloading and filling more gas than necessary
Sometimes people fill CNG at higher pressure than the capacity or load the car more than necessary.
- Danger: Pressure more than 200 bar puts excess pressure on the cylinder. Overloading can damage the gas line below and cause leakage.
- Correct method: Fill gas at standard pressure only and do not load the car more than the prescribed capacity.

5. Parking for long periods in hot sun
A common mistake in summer is to park the car in direct sunlight with the windows closed.
- Danger: Excessive heat increases pressure inside the cylinder. A bad or old cylinder can increase the risk in this situation.
- Right way: Park the car in shady or underground parking and keep the windows slightly open for long periods.
The safety of CNG cars completely depends on regular maintenance and vigilance. Do not take any unusual smells, sounds or changes lightly, as this small precaution can save a big accident.
