Abstract: PURPOSE: To separate and remove foreign matters contained in oil effectively, by repeating upward and downward movement of oil in a plurality of stages, and carrying out several times settlement of a sufficient amount of oil more than the amount of oil required by an internal combustion engine.  
     CONSTITUTION: Lubricating oil or the like supplied from oil recirculating pipe 17 is introduced into settlement promoting chamber 3a after it is filtered by filtering means 20, and flows downward in chamber 3a. Then, it flows upward after passing around clearance 8 formed at the bottom of chamber 3a and overflows into the next settlement promoting chamber 3c. By thus repeating upward and downward movement in a plurality of stages, oil is at last drawn upward from settlement promoting chamber 3b by pump 18 and returned to chamber 3a via suction pipe 16. While oil is made to flow through chambers 3aW3c, heavy matters contained in oil are settled on bottom plates 7 having a steep inclination and dropped through clearances 10 into foreign-matter collecting chamber 11 at the bottom. Oil thus purified is returned to internal combustion engine via outlet pipe 21.

Abstract: PURPOSE:To prevent fuel consumption from getting worse by stopping a feed-back control by a low-load detecting signal of an engine during the time when a feed-back control of ignition timing is carried out on the basis of a crank angle for the maximum inner cylinder pressure. CONSTITUTION:A control circuit 10 detectes a crank angle for the maximum inner cylinder pressure by cylinder pressure sensors 1-4 and a crank angle sensor 7, and carries out the feed-back control of the ignition timing in such a manner that when the air intake rate from a air-flow meter 8 is larger than a predetermined value and if a defference between the detected crank angle for the maximum cylinder inner pressure and the predetermined target value is possitive, the basic ignition timing is advanced by a predetermined value it the difference is negative, it is retarded by a predetermined value. When the air intake rate is smaller than the predetermined value, the engine is judged in a low load condition, and if the corrective value to the basic ignition timing is positive, a predetermined value is subtracted from the corrective value, and if it is negative, a predetermined value is added so as to force the corrective value approach '0' so that the erroneous correction can be avoided by controlling the ignition timing at the value near the basic ignition timing, thus preventing fuel consumption from worsening.
