    摘要： Provided is an internal combustion engine emission control technology that includes: split passages (20, 30) that divide exhaust gas discharged from an internal combustion engine (1) into a plurality of streams; particulate filters (A, B) that are provided individually in the split passages (20, 30), and that remove a component present in the exhaust gas at a high removal rate if a temperature of the exhaust gas that inflows via the split passages (20, 30) satisfies a predetermined temperature condition; and exhaust choke valves (24, 34) that change proportions of amounts of flow of the exhaust gas into the split passages (20, 30) so that the predetermined temperature condition is satisfied in at least one split passage (20, 30) of the split passages. Therefore, it becomes possible to perform emission control over a broadened range of changing temperatures of the exhaust gas. Furthermore, even in a situation where the emission removal rate normally drops, emission control can be performed while avoiding reduction in the emission removal rate as much as possible.

    摘要翻译： 本发明提供一种内燃机排放控制技术没有包括：分流通道（20,30）确实划分从内燃机排出的废气（1）进入的流的多元性; 微粒过滤器（A，B）并分别在分割通道（20，30）提供，并以高的除去率，如果废气的温度确实经由分流通路流入并删除组件存在于废气中（ 20，30）SATIS外资企业预定的温度条件; 和排气节流阀（24，34）确实改变的废气的流量的量的比例到分裂通道（20，30）做了规定的温度条件是在该至少一个分裂通路（20，30）成立 分裂通道。 因此，变得能够在废气的温度变化的范围扩大执行发射控制。 进一步，即使在发射去除速率通常降低的情况下，发光控制可以同时尽可能避免在发射去除率减少执行。
