Title:
METHOD FOR CONTROLLING INTERNAL COMBUSTION ENGINE AND DEVICE FOR CONTROLLING INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2020/183211
Kind Code:
A1
Abstract:
An internal combustion engine (1) has a fuel injection valve (11) that directly injects fuel into a combustion room (2). In the fuel injection valve (11), a fuel attachment amount at a nozzle tip becomes a maximum value when a temperature (Tinj) of the nozzle tip is a prescribed temperature (A). In the internal combustion engine (1), the temperature (Tinj) of the nozzle tip of the fuel injection valve (11) is controlled so as to avoid a temperature range in which the fuel attachment amount becomes the maximum value during startup. As a result, the fuel is not easily attached to the nozzle tip of the fuel injection valve (11) in the internal combustion engine (1). Therefore, the internal combustion engine (1) can suppress an increase in exhaust fine particles in exhaust resulting from the fuel attached to the nozzle tip of the fuel injection valve (11).
