Method of rapidly heating a mass to an operative temperature, in particular a vehicle engine during cold starting

摘要

A method of rapidly heating e.g. a vehicle engine to its operative temperature during cold starting periods. The vehicle engine is in heat exchange relationship with a section of a cooling fluid flow circuit which furthermore includes a sensible heat storage means. The heat carrier is fed into the heat storage means at the beginning of an inoperative period and is re-fed into said fluid flow circuit section in heat exchange relationship with the engine at the beginning of an operative period.
