INTERNAL COMBUSTION ENGINE AND ITS CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide an internal combustion engine and its control method for sufficiently and positively supplying air to a reformer at the start of the engine. SOLUTION: The internal combustion engine 1 is provided with an air supply pipe L1 including a throttle valve 12; a by-pass pipe L2 branched from an air supply pipe intake passage upstream of the throttle valve 12; the reformer 20 connected to the by-pass pipe L2 and reforming a mixture of fuel and air to produce reformed fuel containing predetermined fuel components; and an ECU 30. In starting fuel reforming in the reformer 20, the ECU 30 sets the opening of the throttle valve 12 of the air supply pipe L1 to the minimum and then starts air supply to the reformer 20 through the by-pass pipe L2.
