摘要： A controller for an internal combustion engine is configured to operate the engine at a desired output power and at a desired air/fuel ratio provided in the cylinder, the desired air/fuel ratio depending on an amount of air, the primary fuel, and the secondary fuel provided to the cylinder selectively; gradually increase a power output of the engine during a transient event from an initial power output, to an intermediate power output, and then to a final power output; during the transient event, simultaneously with the power output increase, increase the amount of the primary fuel and the secondary fuel to produce a rich air/fuel ratio in the cylinder.
