摘要： PROBLEM TO BE SOLVED: To provide an internal combustion engine with a secondary air supply device capable of smoothly supplying secondary air and carrying out sufficient secondary combustion without being strongly influenced by exhaust pressure while adopting a structure closing a part of exhaust branch pipes of a plurality of systems. SOLUTION: A secondary air supply port 4 is provided in a downstream side of a first exhaust valve 51a, and secondary air is supplied with closing only the first exhaust valve 51a until temperature of the internal combustion engine reaches a designated temperature in warm up operation. Supplied secondary air merges with exhaust gas passing the open second exhaust valve 51b. Since the first exhaust valve 51a in an upstream of the secondary air supply port 4 is closed, secondary air can be smoothly supplied without being influenced by exhaust gas pressure.

摘要： PROBLEM TO BE SOLVED: To suitably determine fuel property by improving the way of performing active air-fuel control.
SOLUTION: A fuel property determining device actively changes and controls an air-fuel ratio to a lean side or a rich side whenever output Vrr of a post-catalyst air-fuel sensor turns around to the lean side or the rich side and estimates a sulfur concentration of fuel based on at least one of a fluctuation range F and turn-around periods TR, TL of the post-catalyst air-fuel sensor output at that time. A lean turn-around threshold which decides turn-around timing of the post-catalyst air-fuel sensor output from the rich side to the lean side is set at a value VR on a more rich side than the output corresponding to a stoichimetric air-fuel ratio. The fluctuation range F and the turn-around periods TR, TL become varying according to the fuel sulfur concentration so that the fuel sulfur concentration can be suitably estimated based on the fluctuation range F and the turn-around periods TR, TL.

摘要： PROBLEM TO BE SOLVED: To detect deterioration of a catalyst, while differentiating between permanent deterioration and temporal deterioration caused by poisoning. SOLUTION: A catalyst deterioration detection device for an internal combustion engine comprises: a means measuring an oxygen storage capacity of a catalyst; a means for detecting or estimating a catalyst temperature Tc; and a means for detecting the poisoning of the catalyst from a relation between change in catalyst temperature and change in oxygen storage capacity corresponding to the change in catalyst temperature. The change in catalyst temperature (Tb-Ta) and the change in oxygen storage capacity (OSCb-OSCa) corresponding to the change in catalyst temperature has a constant relation, the change in oxygen storage capacity corresponding to the change in catalyst temperature is changed according to presence/absence of the poisoning of the catalyst (a continuous line indicates that the catalyst is not poisoned, and a broken line indicates that the catalyst is poisoned). By utilizing the relation, presence/absence of the poisoning of the catalyst is suitably detected, and the deterioration of the catalyst is detected while the temporal deterioration caused by poisoning of the catalyst and the permanent deterioration is differentiated.

摘要： PROBLEM TO BE SOLVED: To prevent the execution of deterioration detection in a state that a rich component adheres to a catalyst and a sensor in a certain period after starting an internal combustion engine. SOLUTION: When the deterioration detection of a catalyst is executed within a predetermined period (S102: YES) after starting an internal combustion engine, the deterioration detection is executed (S104) by using, as a condition, the presence of a predetermined operation state (for instance, fuel cut F/C) where an exhaust air-fuel ratio on the upstream side of the catalyst is set remarkably lean (S103: YES) before its execution. After a remarkably lean gas is supplied to the sensor before executing the deterioration detection to cause a rich component adhering to the sensor to disappear, the deterioration detection can be executed.
