Self Study Program 427 – The BiFuel LPG Drive

VAG SSP 427. For the first time, Volkswagen is offering the  Golf 2009 with the 1.6l 75kW MPI engine and LPG drive straight from the factory. LPG is also known as liquid gas or autogas. LPG stands for “Liquefied Petroleum Gas”. All components that are required for gas  operation are fitted on the production line at Volkswagen.

LPG has been in use for decades and is currently the most popular alternative fuel across the world. It is made from a mixture of propane, butane and additives. It burns cleanly and is thus among the latest of energy fuels. In many cities, more and more vehicles are being run on LPG due to rising environmental awareness.

Compared with other fuels, LPG produces considerably fewer exhaust emissions. The same applies to carbon dioxide emissions (CO2), which are associated with climate change. On the whole, the exhaust emissions caused by LPG vehicles are among the lowest that can currently be achieved with combustion engines. LPG fuel is virtually sulphur-free and its combustion produces almost no  soot. Hazardous  substances like carbon monoxide (CO), hydrocarbons (HC), nitrogen oxide (NOX) and other health- and environment-harming exhaust gas components are considerably less.
