INTERNAL COMBUSTION ENGINE WITH LIQUID COOLING AND ITS OPERATING METHOD Russian patent published in 2017 - IPC F01P3/02 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, cylinder 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, on inlet side there is coolant supply pump (17). Invention aims at providing an internal combustion engine (1) with optimized cooling system control. Said task is solved by fact that in proposed internal combustion engine a control device (7) is installed at inlet side filled with cooling agent and having two outlets (8a, 8b), from which first outlet (8a) is connected to first inlet hole (2a), and second outlet (8b) is connected to second inlet hole (2b), wherein control device (7) contains single gate (7A), which in first working position opens first outlet (8a) and closes second outlet (8b), thus starting coolant circulation through cylinders block head (1a) and stopping circulation of coolant through cylinders block (1b), and in second working position opens both first (8a) and second (8b) outlets, thus starting coolant circulation through either cylinders block head (1a), and through cylinders block (1b).

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