2. Mechanical efficiency - Wikipedia

   en.wikipedia.org/wiki/Mechanical_efficiency

   In mechanical engineering, mechanical efficiency is a dimensionless ratio that measures the efficiency of a mechanism or machine in transforming the power input to the device to power output. A machine is a mechanical linkage in which force is applied at one point, and the force does work moving a load at another point.

3. Ideal machine - Wikipedia

   en.wikipedia.org/wiki/Ideal_machine

   The mechanical efficiency of a simple machine is calculated by dividing the actual power output by the ideal power output. This is usually expressed as a percentage. Power loss in a real system can occur in many ways, such as through friction, deformation, wear, heat losses, incomplete chemical conversion, magnetic and electrical losses.

5. Two- and four-stroke engines - Wikipedia

   en.wikipedia.org/wiki/Two-_and_four-stroke_engines

   The four-stroke engine is more efficient when running at full throttle, while the opposite is the case for the two-stroke engine. When a small car under heavy load runs at half speed, the engine automatically switches to the two-cycle mode, which is then more efficient. The research on this showed a 27% reduction in fuel consumption. [8] [9]

   Mechanical efficiency, where one form of mechanical energy (e.g. potential energy of water) is converted to mechanical energy ; Thermal efficiency or Fuel efficiency, useful heat and/or work output per input energy such as the fuel consumed; 'Total efficiency', e.g., for cogeneration, useful electric power and heat output per fuel energy ...

9. Talk:Mechanical efficiency - Wikipedia

   en.wikipedia.org/wiki/Talk:Mechanical_efficiency

   I would like to make some revisions to this article to make it more precise and link it to other articles on machines and efficiency. Prof McCarthy ( talk ) 23:57, 26 July 2011 (UTC) [ reply ] I tried to edit this article in a way that kept the spirit of the original material and corrected some errors, but it rapidly became redundant and awkward.
