Abstract

See full text

An engine control device that can suppress thermal degradation of a particulate filter is provided. The device executes a fuel injection control module that restricts the supply of fuel by an injector if a fuel cutting condition is satisfied, an accumulation estimation module that estimates the accumulated amount of soot trapped in a GPF, and a regeneration control module that performs regeneration control for regenerating the GPF by burning soot if the accumulated soot amount exceeds a predetermined setting amount. A fuel cut prohibition line is set in advance and defines a prohibition temperature at which fuel cutting control is to be prohibited in accordance with the accumulated soot amount. The device further executes a prohibition control module that prohibits performance of fuel cutting control by the fuel injection control module if the temperature of the GPF is higher than the prohibition temperature.
