INTERNAL COMBUSTION ENGINE CONTROL DEVICE

摘要

The disclosed internal combustion engine control device is mounted on a vehicle and is provided with an exhaust passage, a reforming catalyst, and a NOx purification catalyst. The exhaust passage communicates with the engine. The reforming catalyst, provided in the exhaust passage upstream from the NOx purification catalyst, reforms CH4 and generates a reducing agent. The NOx purification catalyst purifies NOx by means of the reducing agent generated by the reforming catalyst.
