The maximum theoretical efficiency of a heat engine | Physics Forums - Mechanical efficiency is mechanical advantage/velocity ratio and can be theoretically 100% in the absence of friction. Thermodynamic efficiency is a comparative term that compares the output achieved to the theoretical output of a perfect cyclic machine (Carnot cycle).

How Efficient are Engines: Thermodynamics and - "Internal combustion engines produce mechanical work (power) by burning fuel. During the combustion process the fuel is oxidized (burned). The strict definition of thermal efficiency, according to the Merriam-Webster Dictionary, is, "the ratio of the heat utilized by a heat engine to the total

Heat engine | Efficiencies of Power Plants - ^ Mechanical efficiency of heat engines, p. 1 (2007) by James R.
