CONTROLLING METHOD AND CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE Russian patent published in 2018 - IPC F02D23/00 F02D15/02 F02D41/04 

FIELD: motors and pumps.

SUBSTANCE: invention relates to a control for an internal combustion engine having a mechanism with a variable compression ratio. During the transient acceleration period, during this period the required load is increased, injection pressure rises before the mechanical compression ratio is reduced and the internal combustion engine passes to a high load state. At this time, there is the possibility that the formation of detonation and excessive increase in internal pressure in the cylinders. This probability is a task that must be addressed. Internal combustion engine includes: a mechanism with a variable compression ratio that allows modification of the degree of mechanical compression; turbocharger (2), that pumps in intake air using exhaust gas energy; and exhaust bypass valve (7), that regulates the discharge pressure as a control mechanism for discharge pressure. Degree of mechanical compression is determined by control shaft sensor (34), and the discharge pressure is limited based on this degree of mechanical compression.

EFFECT: control method and a control device for an internal combustion engine are proposed.
