WebIf the engine is idling then the mechanical efficiency is zero because the brake output is zero. The efficiency is maximum at a high power output. A typical value of maximum mechanical efficiency for a reciprocating engine is between 80% and 90%: it is very dependent on the rating (bmep) of the engine. In general, energy conversion efficiency is the ratio between the useful output of a device and the input, in energy terms. For thermal efficiency, the input, , to the device is heat, or the heat-content of a fuel that is consumed. The desired output is mechanical work, , or heat, , or possibly both. Because the input heat normally has a real financial cost, a memorable, generic definition of thermal efficiency is
