Steam Power

Steam Engines using Variable stroke to save Fuel

 

When applied to steam engines The Dynamically Variable Stroke Technology (DVST) allows the stroke to be varied while the engine is running depending on load requirements.

While accelerating large steam quantities are required but when coasting steam usage can be reduced  saving energy.- Question— would steam trains become efficient enough to be used again?

Could Piston steam engines be used for generating electricity efficiently by only using steam when demand requires it but maintaining a constant speed ?

 

Examples of typical designs for this application are :

The ball bearing DVST converter—applied to single cylinder diesel engines.

The journal bearing DVST Converter- applied to multi-cylinder steam engines.

Advantages

Varying the stroke of a steam engine allows only the amount of steam required to propel the load while coasting saving a volume of steam when engine is not calling for power.
