  2. Theory and Construction of a Rational Heat Motor - Wikipedia

    en.wikipedia.org/wiki/Theory_and_Construction_of...

    Diesel's idea of a rational heat motor was designing a cycle that would allow maximum heat utilisation, [9] based on the Carnot cycle. [1] To overcome the low efficiency of steam and combustion engines of the time, Diesel wanted to build an entirely new type of internal combustion engine. [10]

  3. Applications of the Stirling engine - Wikipedia

    It is often claimed that the Stirling engine has too low a power/weight ratio, too high a cost, and too long a starting time for automotive applications. They also have complex and expensive heat exchangers. A Stirling cooler must reject twice as much heat as an Otto engine or diesel engine radiator. The heater must be made of stainless steel ...

    en.wikipedia.org/wiki/Stirling_engine

    Designing Stirling engine heat exchangers is a balance between high heat transfer with low viscous pumping losses, and low dead space (unswept internal volume). Engines that operate at high powers and pressures require that heat exchangers on the hot side be made of alloys that retain considerable strength at high temperatures and that don't ...

    The blue solid line shows the heat flowing out of the cooler heat exchanger. The heat from the cooler and the work from the compression piston have the same cycle energy. This is consistent with the zero-net heat transfer of the regenerator (solid green line). As would be expected, the heater and the expansion space both have positive energy flow.

A hot air engine [1] (historically called an air engine or caloric engine [2]) is any heat engine that uses the expansion and contraction of air under the influence of a temperature change to convert thermal energy into mechanical work.

  9. Engine tuning - Wikipedia

    en.wikipedia.org/wiki/Engine_tuning

    Vintage engine testing equipment that can test ignition timing, ignition dwell, manifold vacuum and exhaust emissions. Engine tuning is the adjustment or modification of the internal combustion engine or Engine Control Unit (ECU) to yield optimal performance and increase the engine's power output, economy, or durability.
