Self Study Program 262 – Natural gas – an alternative fuel for motor vehicles Design and function PDF. Within the process of reducing harmful emissions caused by traffic in built-up cities and the rising costs of petrol and diesel fuel, more emphasis is being placed on natural gas as an alternative power source to drive motor vehicles.
Gas as a power source to drive vehicles is not a modern invention. It has a long history. Even the first internal combustion engine – the patent for which was applied for by Nikolaus Otto in 1876 – was developed in the Deutz AG gas engine factory.
Within the scope of further motor vehicle engine development, gas technology, as well as other drive concepts, was always a source upon which engineers could fall back on – mostly in times of emergency.
This lead to vehicles being equipped with storage tanks, in which town gas or a mixture of propane/butane was filled, or the gas was generated directly in gas generators from wood or anthracite while the vehicle was in motion.
In this day and age, Volkswagen offers the Golf BI FUEL as a series production vehicle with bivalent natural gas drive (vehicle can be driven with natural gas or petrol).
The Transporter ’91 > can be equipped with a retrofit option for bivalent natural gas powered operation.
Please note that there will be country-specific differences with regards to legal requirements. With this self-study programme we would like to introduce you to the special features of the bivalent natural gas drive system for Volkswagen vehicles (centred around the framework conditions in
