INTERNAL COMBUSTION ENGINE WITH LIQUID COOLING AND SUCH ENGINE OPERATING METHOD Russian patent published in 2017 - IPC F01P3/02 F01P3/20 F01P7/16 

FIELD: engines and pumps.

SUBSTANCE: invention relates to internal combustion engine (1) having, at least one cylinder block head (1a) and one cylinders block (1b), wherein at least, one cylinder block head (1a) is equipped with at least one integrated cooling jacket, which has first inlet hole (2a) at inlet side for supply of cooling agent, and first outlet hole (3a) at outlet side to drain coolant, cylinders block (1b) is equipped with at least one integrated cooling jacket, which has second inlet hole (2b) at inlet side for supply of cooling agent, and second outlet hole (3b) at outlet side to drain coolant, and to form cooling circuit outlet holes (3a, 3b) are made with possibility to be connected with inlet holes (2a, 2b) via recirculation line (5), in which heat exchanger (6) is installed, wherein at outlet side control device (7) is installed with two inputs (8a, 8b), first of which (8a) is connected to first outlet hole (3a), and second (8b) is connected to second outlet hole (3b), having first output (9a), made with possibility of connection to, at least, recirculation line (5), as well as having single gate (7A), in first working position opening first input (8a) and closing second input (8b), thus starting coolant circulation through cylinder block head (1a) and stopping circulation through cylinders block (1b), and in second working position opening both inlets (8a) and (8b), thus starting coolant circulation either through cylinders block head (1a) and through cylinders block (1b).

EFFECT: invention provides thermal control at warming-up stage and, if necessary, effect on warmed-up engine thermal control.
