Why external combustion engine is not used?
Why external combustion engine is not used? An external combustion engine is unique from other EHEs because it requires a fuel to undergo combustion to create the heat that is used for work. External combustion engines are no longer used in transportation, as mobile designs are not efficient enough, but they continue to be used […]
