CNG Safety

Information CNG = Compressed Natural Gas 

The combustion point of CNG in air at 20°C is between 4 volume % and 15 volume %. Density is 0.72 proportion to air. This means that the CNG which flows into the air rises rapidly and dissipates. There is the risk of explosion if CNG leaks out into unventilated spaces. Compressed Natural Gas (CNG) is stored in the car as a gas.

The integral system safety consists of: 

• A thermal fuse in the tanks which opens at 103°C 
• All fuel tank units are positioned outside the passenger compartment - either in the engine compartment or under the car. This is classified as an external installation
• A solenoid valve which immediately closes off all gas supply if the engine stops
• Manual shut-offs
• The gasoline system is available as a reserve if the gas (CNG or LPG) fuel system does not function or runs out of gas.
