摘要： PROBLEM TO BE SOLVED: To improve the catalyst early warming-up effect while improving the exhaust emission during the period of low catalyst temperature in an initial stage when the catalyst early warming-up control is started.
SOLUTION: Irregular injection dither control is performed during the catalyst early warming-up control after an engine is started. In this irregular injection dither control, the lean injection to inject fuel so that the air-fuel ratio is not stoichiometric but rich for each fuel injection of each cylinder (every 180°CA for a four-cylinder engine) and the rich injection to inject fuel so that the air-fuel ratio is not stoichiometric but rich are switched by the pattern so that the rich injection is not continuous to the same cylinder (the dither period = 540°CA, 900°CA, 1,080°CA, etc.). Rich gas exhausted from the cylinder of rich injection is not deviated in the same area in the catalyst, but flows in different areas for each injection. By efficiently mixing rich gas with lean gas in the catalyst, the oxidation reaction of the rich element in the catalyst is promoted.

摘要翻译：待解决的问题：在开始催化剂早期预热控制的初始阶段，为了提高催化剂早期预热效果，同时改善在低催化剂温度期间的排气排放。
解决方案：发动机启动后的催化剂早期预热控制期间执行不规则喷射抖动控制。在这种不规则喷射抖动控制中，注入燃料的稀薄喷射使得空燃比对于每个气缸的每次燃料喷射（对于四缸发动机每180°CA）而言不是化学计量的而且是丰富的，燃料，使得空燃比不是化学计量的，但通过模式切换浓，使得富喷射不与同一气缸连续（抖动时间= 540℃，CA 900°CA，1080°CA等）。从富注射筒中排出的富气不会在催化剂的相同区域偏离，而是在不同的区域进行注射。通过在催化剂中有效地将富含气体与稀薄气体混合，可促进富含元素在催化剂中的氧化反应。版权所有（C）2005，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To effectively reduce the discharge of hydrocarbon from an internal combustion engine. SOLUTION: In the engine, a secondary air is supplied from a secondary air supply pump 33 to an exhaust tube 21 through an exhaust side air passage 32. Also, an intake side air passage 35 is connected so as to be branched from the exhaust side air passage 32, and the tip of the intake side air passage 35 is connected to an intake manifold 16. An HC adsorbing material 31 is installed in an air cleaner 12 on the upstream-most side of the intake tube. An ECU 50 fills air to the intake manifold 16 by driving the secondary air supply pump 33 when the engine is stopped. Thus, the hydocarbon suspending near the intake port is forced out toward the upstream side of the intake tube 11, and adsorbed onto the HC adsorbing material 31. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To effectively reduce the discharge of hydrocarbon from an internal combustion engine.
SOLUTION: A canister 33 is connected to the intake manifold 16 of the engine 10 through purge piping 34. The canister 33 temporarily stores a fuel evaporative emission generated in a fuel tank 31, and when a purge control valve 35 is opened during the operation of the engine, the adsorbed fuel in the canister 33 is discharged. A leak check module 40 is connected to the canister 33, and the suction of air is performed by a suction pump 43 when a fuel evaporative emission flow passage is checked for leakage. An ECU 50 drives the suction pump 43 during the stoppage of the engine to suck the hydrocarbon suspending near the intake port through a purge tube 34. Thus, the hydrocarbon suspending near the intake port is adsorbed onto the canister 33.
