What is CNG & How Does It Work?
CNG (Compressed Natural Gas) is an eco-friendly fuel which is stored in a cylinder at high pressure (200 bar).
The gas is taken out from the cylinder and goes to the engine through the fuel line, where the engine runs after ignition. This makes it clear that this is a high pressure gas and it is very important to follow its safety norms.
Why Do CNG Cars Blast in Summer?
- Extreme Heat
In summer, the temperature reaches 45-50°C, which increases the pressure inside the fuel tank and increases the chances of the tank bursting.
If the pressure release valve or cylinder testing is not done properly, the risk of blast increases.
- Faulty or Aftermarket CNG Kits
Use CNG kits approved by our RTO, using non-RTO approved kits is the biggest reason for blast.
Sometimes local fitting shops do not follow safety rules like loose wiring, poor quality pipes, weak joints. This is also a reason for blast.
- Neglected Cylinder Testing
According to RTO rules, it is mandatory to get cylinder hydro tested every three years. Without testing the cylinder becomes weak, which may blast in summer.
4. Gas Leakage & Poor Maintenance
If there is a leakage or faulty shut-off valve in the CNG line, the gas accumulates, which can explode with a small spark.
5. Illegal Modifications
Sometimes people make wrong modifications like parcel tray on cylinder, placement of AC condenser in the heat area – all are illegal and dangerous modifications. Some people get an extra tank fitted which is outside the company design.
Real Cases in India (2024–2025 Highlights)
| Location | Car Type | Blast Reason | Outcome |
| Delhi | Wagon R (CNG) | Cylinder pressure valve fail | 1 injured |
| Kanpur | Local CNG Kit Alto | Gas leakage spark | Car total loss |
| Pune | Taxi (CNG) | No cylinder testing for 5 years | Fatal |
