Abstract
A wastegate sealing jig (13) includes a base (14) which is fixable to an exhaust portion (11) of a turbocharger (1), the base (14) including a wastegate valve (6), and a turbine hole (12) which discharges exhaust gas in a turbine chamber (4b), a protrusion (15) which is provided in the base (14) so as to extend toward the exhaust portion (11), a valve member (16) which is attached to a distal end of the protrusion (15). The wastegate (5) is closed by the valve member (16) by inserting the valve member (16) between the wastegate (5) and the wastegate valve (6) of the turbocharger (1) in a state in which the wastegate valve (6) is opened.
Claims8
A wastegate sealing jig, comprising:
- a base which is fixable to an exhaust portion of a turbocharger, the turbocharger including the exhaust portion which forms an exhaust opening, the base including a wastegate, a wastegate valve capable of closing the wastegate by covering an open end on an exhaust side of the wastegate, an opening and closing rotation shaft which opens and closes the wastegate valve, and a turbine hole which discharges exhaust gas from a turbine chamber in which a turbine wheel is housed;
- a protrusion which is provided in the base so as to extend toward the exhaust portion in a region excluding the wastegate;
- and
- a valve member which is attached to a distal end of the protrusion,
- wherein the wastegate is closed by the valve member by inserting the valve member between the wastegate and the wastegate valve of the turbocharger in a state in which the wastegate valve is opened.
