Thank you for your post, There are good post! Developed the Common Rail fuel system for heavy duty vehicles and turned it into practical use on their ECD-U2 common-rail system.Modern common rail systems, whilst working on the same principle sensor are governed by an engine control unit (ECU). The design was acquired by the German Common Rail Shim & Gasket kit companyRobert Bosch GmbH for completion of development and refinement for mass-production Common Rail Nozzle . In...

Sadi Carnot Against the Second Law of Thermodynamics

Carnot's (false) postulate: Heat is an indestructible substance (caloric) that cannot be converted into work by the heat engine.

Consequence (prototype of the second law of thermodynamics) : As the heat engine produces work, A COLD BODY IS NECESSARY.

That is, since the heat is not...
