Vehicle gas

The vehicle gas used in Scania gas vehicles is biogas, natural gas, or a mixture
of these.
Vehicle gas is primarily made up of methane and has a methane content of 75-
97%. Methane is a highly flammable gas that has explosive limits at 5-16%
mixture in air. The gas self-ignites at a temperature of 595°C.
Vehicle gas is essentially colourless and odourless. Pressurised vehicle gas,
CNG, is often mixed with odorants to enable leakages to be detected. Liquid
vehicle gas, LNG, has no added odour, but major leakages are visible as a mist
as the water in the air condenses when it is cooled down by the throttle.
Methane is lighter than air and therefore rises in the event of leakage. This
should be taken into account when leakages occur, for example indoors or in a
tunnel. The gas can cause suffocation in confined spaces. Liquid and cold
methane gas is heavier than air and can run into low points in the event of
leakage. Therefore, ensure good ventilation.
Plate
Gas vehicles are marked at several points with a diamond-shaped symbol with
the text CNG or LNG.
Pressurised vehicle gas, CNG
CNG stands for Compressed Natural Gas. The gas tank packages consist of a
number of gas tanks which are positioned together. A truck with a full tank can
hold up to 150 kg of fuel.
The pressure in the gas tank and the fuel system can exceed 230 bar when
refuelling.
