Mixed-combustion electronic control device

Abstract

This mixed-combustion electronic control device includes a first controller (11) that controls combustion of a first fuel and a second controller (12) that controls mixed combustion of the first fuel and a second fuel. The second controller (12) stores, for each engine operating condition, observation values (for example, the extreme value of the rotation speed of the crankshaft and the extreme value timing) corresponding to the combustion timing of the first fuel (S504). The second controller (12) learns the observation values corresponding to the combustion timing of the first fuel suitable for each operating condition (S503). The second controller (12) determines whether to perform mixed combustion from the current operating conditions and learning situation (S505). In a case where it is determined that mixed combustion is to be performed, the second controller (12) controls the mixed combustion by using the learned observation values (S506).
