DETERMINATION OF EXTENT OF FEED OF EXHAUST GASES RECYCLED (EGR) TO ICE CYLINDER INLET AND ICE FOR CLAIMED PROCESS IMPLEMENTATION Russian patent published in 2016 - IPC F02D41/00 F02M25/07 

FIELD: engines and pumps.

SUBSTANCE: invention can be used in internal combustion engine control systems. It discloses the determination of extent of EGR feed to ICE cylinder (10) at time t. Here, said exhaust gases are forced into return channel (14) communicating the ICE exhaust line (200) and its intake line (100). Said EGR feed extent equals the ratio between the EGR flow rate and total flow rate in intake line at analyzed point and analyzed time moment at said intake line. Claimed process comprises the steps that follow. a) Defined is the time moment t_intro antecedent to time moment 7 when gas forced to cylinder inlet at time moment t is fed into intake line. b) Defined is the extent of EGR feed extent at return pipeline outlet into intake line (100) at time t_intro. c) Defined is the extent of EGR feed at time t depending on that at return line outlet into intake line at time t_intro defined at step b). Invention discloses also the ICE including electronic control unit (30) programmed to implement the above described process.

EFFECT: higher accuracy of EGR feed extent at every time moment.
