Multifuel

One common application of multifuel technology is in military settings, where the normally-used diesel or gas turbine fuel might not be available during combat operations for vehicles or heating units.

Multifuel engines and boilers have a long history, but the growing need to establish fuel sources other than petroleum for transportation, heating, and other uses has led to increased development of multifuel technology for non-military use as well, leading to many flexible-fuel vehicle designs in recent decades.

For instance, some heaters and boilers designed for home use can burn wood, pellets, and other fuel sources.

[6] Portable stoves are sometimes designed with multifuel functionality, in order to burn whatever fuel is found during an outing.

[7] Innovative industrial heaters or burners were the subject of multi-fuel research at a Shell plant in 2014.

Perhaps the most notorious example from a military perspective is the L60 engine used by the British Chieftain Main Battle Tank, which resulted in a very sluggish performance – in fact, the Mark I Chieftain (used only for training and similar activities) was so underpowered that some were incapable of mounting a tank transporter.
