摘要： A cylinder head assembly for an internal combustion engine is provided. In one example implementation, the cylinder head assembly includes a cylinder head, a bypass passage formed within the cylinder head and defining a catalyst cavity, and a bypass catalytic converter disposed within the catalyst cavity, where the bypass catalytic converter is configured to provide emissions reduction during cold start, long idle, and/or low main catalytic converter temperature conditions.
