Title:
ENGINE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2019173649
Kind Code:
A
Abstract:
To promote the evaporation of fuel before ignition more than before by taking heat damage measures of a fuel injection valve.SOLUTION: In an engine control device for at least controlling an intake valve, an exhaust valve and a fuel injection valve so as to perform internal EGR on the basis of a crank angle of an engine having the fuel injection valve for injecting fuel into an intake pipe, the valve-opening timing and the valve-closing timing of the intake valve are retarded compared with a reference operation state being a first operation state, and the valve-closing timing of the exhaust valve is advanced compared with the reference operation state, and in a period in which the intake valve is valve-closed and valve-opened after a piston starts to rise after the piston firstly passes a bottom dead point after a finish of an exhaust stroke, the fuel injection valve injects the fuel.SELECTED DRAWING: Figure 3
