lämpökoneistosta

Lämpökoneisto is a Finnish term that translates to "heat engine" in English. A heat engine is any device that converts thermal energy into mechanical energy. This mechanical energy can then be used to do work, such as powering a vehicle or generating electricity. The fundamental principle behind a heat engine is the transfer of heat from a hotter reservoir to a colder reservoir, and the extraction of work during this process.

The operation of a heat engine typically involves a working fluid, such as steam or a gas, that undergoes a cycle of changes. This cycle usually involves heating the fluid, allowing it to expand and do work, cooling the fluid, and then returning it to its original state. Common examples of heat engines include internal combustion engines found in cars and external combustion engines like steam engines. Thermodynamic laws, particularly the second law of thermodynamics, govern the efficiency of heat engines, setting limits on how much heat can be converted into work. No heat engine can be 100% efficient; some heat will always be lost to the colder reservoir. The efficiency of a heat engine is a crucial factor in its design and application, influencing fuel consumption and environmental impact.
