Title: Control device for internal combustion engine
Inventor: KADOWAKI HISASHI
IPC: G01M15/04
Filed: 1998-08-21
Abstract: PROBLEM TO BE SOLVED: To reduce knocking and to precisely protect an internal combustion engine by furnishing an abnormality detection means to detect abnormality of a valve timing adjusting device and by performing fail-safe of the internal combustion engine by a fail-safe means at the time when abnormality is detected. SOLUTION: A rotation phase difference against a crankshaft 11 of a camshaft 15 is adjusted by raising pressure of oil by a pump 46 in an oil tank 45, supplying oil to a valve timing control mechanism 50 through a spool valve 40 and adjusting oil quantity at that time. As this valve timing adjusting device 50 is controlled so as to make a relative rotational angle VT follow a target relative rotational angle VTT, it is possible to judge it as abnormality of the relative adjusting device 50 at the time when a state of VT deviated out of VTT by more than a specified value continues for more than specified time. Additionally, when it is judged as abnormality of this adjusting device 50, other abnormality detection is forbidden and knocking generation is previously prevented by fail-safe-controlling an internal combustion engine on an ECU 30.

Filed: 1998-08-21
Abstract: PROBLEM TO BE SOLVED: To detect occurrence of a jam even when a detecting means cannot detect a rear edge of paper, and to accurately detect that a jam has not occurred even when the time for paperless state is short. SOLUTION: When paper feeding starts, a time measuring means 11 starts to measure time, and at the same time, a judgment process means 11 retrieves from a memory means 12, a theoretical time T1 which is the theoretical time it takes for a rear edge of a first paper to pass through and to change from a paper present state to a paper absent state, and a theoretical time T2 which is the theoretical time it takes for a front edge of a second paper to pass. After the measured time of the time measuring means 11 passes the time T1, it is judged whether or not a paper absent state was detected by a detecting means 10. If a paper absent state is detected, it is judged normal.  If a paper present state is detected, there is a possibility that a jam has occurred, so time is measured furthermore and if the detecting means 10 continues to detect a paper present state till the measured time reaches the time T2, it is concluded that a jam has occurred.
