摘要： PROBLEM TO BE SOLVED: To determine the cause of combustion variation in an internal combustion engine recirculating reformed gas obtained by reforming the mixture of exhaust gas and fuel. SOLUTION: This internal combustion engine 1 comprises a reformer 20 generating the reformed gas including hydrogen by reforming the mixture of the exhaust gas and the fuel with a reforming catalyst and refluxing the reformed gas into a combustion chamber through an intake passage and a combustion pressure sensor 48 detecting combustion state in the combustion chamber. When the combustion pressure sensor 48 detects the combustion variation beyond an allowable value, the temperature of the reforming catalyst installed in the reformer 20 is raised to determine whether the combustion variation is caused by the lowering of the performance of the reforming catalyst or by the properties of the reforming fuel Fr supplied to the reforming catalyst.

摘要： PROBLEM TO BE SOLVED: To provide a technique to judge whether the given fuel is appropriate accurately, the fuel being supplied to an engine which performs self-firing combustion. SOLUTION: The engine can operate in two ways, one is the ignition operation in which ignition is made in the ignition part at a timing before the piston reaching the upper dead center and the other is the self-firing priority operation in which the ignition by the ignition part is not conducted or ignition is made by the ignition part at a timing delayed from the ignition operation. To judge whether the fuel is appropriate, first the engine is operated in the self-firing priority operation after the start of the engine. When a specified period has passed since the engine was started, judgement is passed that the fuel does not suit the self-firing if the rotating speed per unit time of a crank shaft does not reach the threshold. Thereby the combusting condition can be judged accurately to allow sensing the appropriateness of the fuel. COPYRIGHT: (C)2004,JPO&NCIPI
摘要翻译：要解决的问题：为了提供一种用于判断给定燃料是否适当准确的技术，燃料被供给到执行自燃燃烧的发动机。
解决方案：发动机可以以两种方式操作，一种是点火操作，其中在活塞到达上止点之前的定时点火点火部分，另一种是自燃优先操作，其中点火部件的点火不会在点火操作延迟的定时由点火部件进行点火。为了判断燃油是否合适，首先在发动机起动后，自发燃料优先操作中发动机运转。当发动机启动后经过规定的时间后，如果曲轴每单位时间的转速未达到阈值，则判断燃料不适合自燃。因此，可以准确地判断燃烧条件以允许感测燃料的适当性。版权所有（C）2004，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To easily detect the ignition timing of an internal combustion engine to be operated by compression self-ignition.
SOLUTION: In the internal combustion engine operated while switching a compression self-ignition operation for operating the engine by compression self-ignition of air-fuel mixture in a combustion chamber and a spark ignition operation for operating the engine by spark ignition of air-fuel mixture in the combustion chamber, current is carried to a primary coil also during the compression self-ignition operation. According to this, since a voltage is applied between the electrodes of an ignition plug by the induced electromotive force generated in a secondary coil, the ion current generated in the ignition can be detected. In such a method, the ignition can be detected also in the compression self-ignition by the extremely easy method of only driving the ignition coil similarly to the spark ignition. When the start timing of the current-carrying to the coil is changed according to the ignition timing, the ion current can be detected without being influenced by noise.
