Abstract
An engine device having a flywheel housing (7) in which a flywheel that is rotated integrally with a crankshaft (5) is accommodated on one side portion (303) of a cylinder block (6), in which the cylinder block (6) is integrally formed with housing bracket portions (304) each protruding in a direction away from the crankshaft (5) from each of opposite side portions (301) of the cylinder block (6) extending along a crankshaft axial direction (300), the housing bracket portions (304) protruding from end portions of the opposite side portions (301) close to the one side portion (303) A space surrounded by the one side portion (303), the housing bracket portions (304), and the flywheel housing (7) constitutes a gear case (330) for accommodating therein a gear train.
Claims5
An engine device comprising a flywheel housing in which a flywheel that is rotated integrally with a crankshaft is accommodated on one side portion of a cylinder block,
- wherein the cylinder block is integrally formed with housing bracket portions each protruding in a direction away from the crankshaft from each of opposite side portions of the cylinder block extending along a crankshaft axial direction, the housing bracket portions protruding from end portions of the opposite side portions close to the one side portion, and a space surrounded by the one side portion, the housing bracket portions, and the flywheel housing constitutes a gear case for accommodating therein a gear train, and
- wherein the gear train includes:
- a crank gear fixed to the crankshaft:
- an idling gear meshed with the crank gear, a cam Rear fixed to a camshaft and meshed with the idling gear, and a pump gear fixed to a pump shaft of a fuel feed pump and meshed with the idling gear, and wherein the flywheel housing has an attaching part for a crank rotation angle detector configured to detect a rotation angle of the crankshaft and an attaching part for a rotation shaft rotation angle detector configured to detect a rotation angle of the cam gear or the pump gear.
