LPG (Liquified Petroleum Gas) is a gas obtained as a by-product in the processing of crude oil in refineries. It is liquefied by pressing and cooling, which significantly reduces its volume. LPG is a mixture of hydrocarbon gases consisting of propane and butane, i. j. saturated hydrocarbons C3 and C4 and is used as a fuel in automobiles. Qualit of LPG is regulated in the STN EN 589 standard.
The properties of LPG are very similar to petrol, which is the main reason for its use in passenger vehicles. LPG is a fuel with very good combustion properties. In our climate conditions we use summer and winter mixtures depending on the time period in combination with average temperatures. The summer mixture consists of 40% propane and 60% butane, winter mixture consists of 60% propane and 40% butane.
LPG labeling
Under current European legislation, all Member States are required to label dispensers at petrol stations with a single symbol. This is linked to meeting environmental requirements for reducing CO2 emissions from fuels and promoting the use of alternative fuels, including LPG. From the point of view of the environment and the health of the population has LPG more favorable parameters. CO2 savings compared to traditional fuels is 20%, NOx savings compared to diesel engines is 74%. LPG significantly reduces the formation of solid emissions (soot, smoke, dust).
At petrol station is LPG labeled by a diamond symbol and the letters LPG.
