Internal combustion engine control device

An internal combustion engine control device to be applied to an internal combustion engine including a cylinder, an intake passage through which air introduced into the cylinder flows, an exhaust passage through which exhaust gas discharged from the cylinder flows, and an exhaust gas recirculation device configured to recirculate, into the intake passage, part of the exhaust gas flowing through the exhaust passage as exhaust gas recirculation gas, the internal combustion engine being configured such that gaseous fuel is supplied into the cylinder, wherein:

• the exhaust gas recirculation device includes an exhaust gas recirculation passage that is connected to the intake passage and through which the exhaust gas recirculation gas flows toward the intake passage, and a collection device configured to collect condensed water generated in the exhaust gas recirculation passage;
• and
• the internal combustion engine control device is configured to
• determine, when the exhaust gas recirculation gas is introduced into the intake passage via the exhaust gas recirculation passage, whether condensed water is generated in a joining portion of the intake passage to which the exhaust gas recirculation passage is connected,
• determine whether the internal combustion engine is in a high-load operation based on a rotational speed of an output shaft of the internal combustion engine and an output torque of the internal combustion engine, and
• reduce an amount of collection of the condensed water by the collection device when determination is made that the condensed water is generated in the joining portion of the intake passage and the internal combustion engine is in the high-load operation.
