Autogas (engine gas, gas oil) or Liquified Petroleum Gas (LPG) consists mainly of propane (C3H8) and butane (C4H10). These gases, which are gaseous under normal atmospheric conditions, are obtained during the distillation of crude oil. The product obtained is then liquefied under pressure to be stored, transported and refueled.
In Belgium, for autogas, the distribution between propane and butane in the winter is 70/30 and in the summer 60/40.
Driving on LPG / Autogas
More information about LPG can also be found on the LPG platform of the federation Autogas.be. The attached video also provides more information about the benefits of driving on LPG.
Main properties of LPG
• a high octane number (according to RON method). Premium petrol has an octane rating of approximately 99, Euro-lead free 95 and LPG over 100. This higher octane rating means that LPG ignites more evenly. Unlike other fuels, no additives are required to ensure high quality.
• lead free
• odorless: a harmless odor is added (detection)
• not agressive
• low viscosity: burns without waste to H2O and CO2 and therefore does not contaminate pipes and / or engine parts
