Title: Ignition timing controller for internal combustion engine
Inventor: SUZUKI NORIO
IPC: F02P5/152
Filed: 1996-08-29
Abstract: PROBLEM TO BE SOLVED: To enable an ignition timing to be controlled properly by means of a simple and low cost constitution by setting an observer for observing the inside state of an engine on the basis of a model for describing behavior of the exhaust system of the engine and by providing an air/fuel ratio estimating means per cylinder for estimating the air/fuel ratio of each cylinder on the basis of the output of an air/fuel ratio detecting means. SOLUTION: Firstly, a basic fuel quantity matching the sucked air quantity is computed in ECU 5 during operation of an engine 1. In addition, a target air/fuel ratio factor is determined in compliance with the engine number of revolution, and air sucking line inside absolute pressure, etc., and also the target air/fuel ratio factor is corrected depending upon the output of an O2 sensor 18. Furthermore, on the basis of an air/fuel ratio at an exhaust manifold part detected by an LAF sensor 17, an air/fuel ratio of each cylinder is estimated and also a corrective factor per cylinder is calculated by PID control so that the air/fuel ratio of each cylinder may coincide with the air/fuel ratio at manifold part.  And in compliance with a deviation of a detected air/fuel ratio from the target air/fuel ratio, PID corrective factor is calculated by PID control, and a fuel injection quantity per cylinder is calculated by taking each corrective factor into account.

Filed: 1989-09-22
Abstract: PURPOSE:To automate cleaning action and achieve a low cost by inter-locking a diaphragm in a cleaning chamber with reciprocation of a plunger to actuate it for sending cleaning liquid automatically. CONSTITUTION:A plunger 24 reciprocates by rotation of a cam 32a to change the volume of a pump chamber 16 and send liquid from a check valve 18 toward a check valve 20. A diaphragm 38 is moved according to the reciprocation of a shaft 28a to change the volume of a cleaning chamber 34a. When the shaft 28a moves right to increase the volume of the cleaning chamber 34a, cleaning liquid is sucked. When the shaft 28a moves left to decrease the volume of the cleaning chamber 34a, cleaning liquid is discharged. Cleaning action is thus automated, and a low cost can be realized.
