Editing Tank (section)

=== Engine ===
The tank's power plant supplies [[kinetic energy]] to move the tank, and [[electric current|electric]] power via a [[Electrical generator#Vehicle-mounted generators|generator]] to components such as the [[gun turret|turret]] rotation motors and the tank's electronic systems.

The tank power plant evolved from predominantly petrol and adapted large-displacement aeronautical or automotive [[internal combustion engines|engines]] to [[diesel engine]]s. Japan was the first to begin transitioning to this engine type beginning with the [[Type 89B]] in 1934. The main advantage of diesel is their higher [[fuel efficiency|fuel economy]], which allows for greater operating ranges. Diesel engines can also run on a variety of fuels, such as aviation kerosene and even gasoline. Advanced [[multi-fuel]] [[Diesel engine#Quality and variety of fuels|diesel engines]] have been adopted.{{sfn|Ogorkiewicz|1991|p=247-249}} [[Gas turbine#Tanks|Gas turbines]] are powerful per unit weight but fuel-hungry; they have been used in a few tanks, including the Soviet [[T-80]] and American [[M1 Abrams]].
