摘要

PPROBLEM TO BE SOLVED: To shorten time required for oxidizing and removing particulates collected by a filter and more successfully oxidize and remove the particulates, in exhaust emission control of a compression ignition internal combustion engine. PSOLUTION: The compression ignition internal combustion engine is provided with an intake throttle valve, an exhaust throttle valve and the filter in which a catalyst having an oxidation function is carried and which collects particulates in exhaust gas. In the compression ignition internal combustion engine, the temperature of the filter is increased by: controlling injection timing of main injection injm and post-injection inja to a timing delay state when openings of the intake throttle valve and the exhaust throttle valve are set to be a throttle side opening (opening 10%) and an opening at the time of first temperature rise (10%), respectively; and then shifting the opening of the intake throttle valve from the throttle side opening (opening 10%) to an open side opening (opening 100%) and shifting the opening of the exhaust throttle valve to an opening at the time of second temperature rise (50%) more widely opened compared to the opening at the time of first temperature rise (10%).

要解决的问题：在压缩点火内燃机的废气排放控制中，为了缩短氧化和去除过滤器收集的颗粒所需的时间，并更成功地氧化和去除颗粒。

解决方案：压燃式内燃机具有进气节气门，排气节气门和过滤器，在所述过滤器中携带具有氧化功能的催化剂并收集废气中的颗粒。在压燃式内燃机中，通过将进气节气门和排气节气门的开度设定为开度，将主喷射喷射和后喷射喷射的喷射正时控制为正时延迟状态，来提高过滤器的温度。节气门侧开度（开度10％）和第一次温度上升时的开度（10％）;然后在第二次升温时将进气节气门的开度从节气门侧的开度（开度为10％）转移到开路的侧开度（开度为100％），然后将排气节气门的开度转变为开度相较于第一次温度上升时的开度（10％），开度更宽（50％）。
