Internal combustion engine and method of controlling the same

摘要

The internal combustion engine includes a reformer for reforming a fuel air mixture of a predetermined fuel and air to produce a reformed fuel, a bypass pipe for supplying air to the reformer, an on-off valve provided in the bypass pipe, and an ECU. The ECU makes the on-off valve open to start a fuel reforming operation in the reformer when a pressure at a position downstream of the on-off valve is lower than a pressure at a position upstream of the on-off valve.
