METHOD OF AND SYSTEM FOR WARMING INTERNAL COMBUSTION ENGINE AND HEATING SALOON OF VEHICLE Russian patent published in 2007 - IPC F02N17/04 

FIELD: transport engineering.

SUBSTANCE: proposed method of warming engine and heating saloon of vehicle provides accelerated and safe removal of heat by liquid heat carrier from elements of heating unit heated to temperature Т₁ under conditions Т_в<Т₁<Т_д where Т_g is boiling temperature of liquid heat carrier, Т_g is temperature of gases at outlet of exhaust manifold of internal combustion engine. Proposed engine warming and saloon heating system contains heating unit with heat accumulator charged by exhaust has heat. Heating unit is built into exhaust gas outlet channel and into heat carrier (TOSOL) circulation circuit. Overall dimensions and mass of heating unit are reduced owing to use of special heat insulation. Main functional operating conditions of system are pre-starting warming of cold engine and vehicle saloon, and when engine is operating, charging of heat accumulator and heating of vehicle saloon. Invention provides use of heat of exhaust gases for improving heating of saloons of vehicles of all types powered by liquid-cooled internal combustion engine and heaters built into engine cooling system.

EFFECT: improved warming up of engine and heating of saloon.
