Title:
CONTROL METHOD AND CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2021/001670
Kind Code:
A1
Abstract:
The present invention discloses a control method for an internal combustion engine in which exhaust gas after combustion is circulated inside a cylinder as EGR gas. The control method involves determining whether a fuel cut condition has been established for performing a fuel cut to temporarily stop the supply of fuel to the internal combustion engine, and when the fuel cut condition is established, closing an intake shutter valve installed on an upstream side in an intake passage from a connection point of an EGR passage, reducing the effective cross-sectional area of the intake passage compared to that before the establishment of the fuel cut condition, and furthermore, after the intake shutter valve is closed, continuing the combustion inside the cylinder during a delay in the transport of the EGR gas from the connection point of the EGR passage to an intake port of the internal combustion engine.
