Abstract

TO ALLOW BLOW-BY GAS EXISTING BETWEEN A CYLINDER HEAD AND A CYLINDER HEAD COVER TO BE SUCKED INTO AN INTAKE PASSAGE COMMUNICATED TO A CYLINDER AND BURNED IN THE CYLINDER WITHOUT MIXING OIL MIST WITH THE BLOW-BY GAS SO THAT OIL WILL NOT BE USELESSLY CONSUMED. AN ENGINE 1 COMPRISES: A CYLINDER HEAD 7; A CYLINDER HEAD COVER 9 ATTACHED TO AN UPPER SIDE OF THE CYLINDER HEAD 7 TO FORM A CAM CHAMBER 8 IN CONJUNCTION WITH THE CYLINDER HEAD 7; A CAMSHAFT 14 DISPOSED IN THE CAM CHAMBER 8 AND SUPPORTED ON AN UPPER SIDE OF THE CYLINDER HEAD 7 FOR ROTATION R ABOUT AN AXIS 11 EXTENDING GENERALLY HORIZONTALLY; A PARTITION PLATE 40 ATTACHED TO A LOWER SIDE OF THE CYLINDER HEAD COVER 9 TO FORM A BREATHER CHAMBER 39 IN CONJUNCTION WITH THE CYLINDER HEAD COVER 9; A COMMUNICATION PASSAGE 41 FORMED THROUGH THE PARTITION PLATE 40 FOR COMMUNICATING THE SIDE OF THE CYLINDER HEAD 7 AND THE BREATHER CHAMBER 39 TO EACH OTHER; AND A GAS PASSAGE 42 FOR COMMUNICATING AN INTAKE PASSAGE 30 COMMUNICATED TO A CYLINDER 6 AND THE BREATHER CHAMBER 39 TO EACH OTHER. THE COMMUNICATION PASSAGE 41 HAS A LOWER OPENING 49 ON THE SIDE OF THE CYLINDER HEAD 7 WHICH OPENS IN A DIRECTION ALONG THE AXIS OF THE CAMSHAFT 14.
