An ECU is applied to a hybrid vehicle that is equipped with an internal combustion engine and a second motor-generator, which are configured to output a driving force for running. The hybrid vehicle is configured to run with the internal combustion engine in intermittent operation. Also, the ECU is configured to calculate an amount of dilution water that is mixed into oil in the internal combustion engine to dilute the oil. The ECU is configured to operate the internal combustion engine when the amount of the dilution water becomes larger than a first threshold.

Control apparatus and control method for hybrid vehicle

A waterproof connecting structure for a pipe for connecting an intake passage of an internal combustion engine and an external gas detector to convey gas into the intake passage. The structure includes a connecting space to which the pipe is connected and a partition wall formed between the intake passage and the connecting space. The connecting space has a larger diameter than the pipe. The partition wall includes an elongate hole for placing the interior of the intake passage and the connecting space in fluid communication. This configuration prevents intrusion of droplets drifting in through intake air and allows a high degree of freedom for location of the pipe.
