Gasket for internal combustion engine

A gasket for an internal combustion engine comprising a plurality of annular plates that are stacked, the gasket being disposed between connection members of parts forming an exhaust gas passage of the engine to form the passage inside of annular plates, wherein

• each of the plurality of annular plates includes:
• a through-hole forming the exhaust gas passage with the gasket assembled between the connection members;
• an inner circumferential portion forming the through-hole;
• a plurality of bolt holes surrounding the through-hole;
• an outer circumferential portion having the plurality of bolt holes therein;
• and
• an intermediate portion disposed between the inner and outer circumferential portions,
• the plurality of annular plates include:
• a grommet plate disposed in a center in a stacking direction of the plurality of annular plates, and having a fold-back portion in the inner circumferential portion;
• and
• first and second seal plates stacked on portions of both sides of the grommet plate in a thickness direction of the grommet plate, and each having a bead in the intermediate portion,
• the inner circumferential portion of the first seal plate is wrapped or held by the fold-back portion of the grommet plate,
• the internal combustion engine gasket further comprises a spacer member formed between the grommet plate and the first or second seal plate in the outer circumferential portions of the plurality of the annular plates so as to include all of the plurality of bolt holes and to extend along the entire circumference of the outer circumferential portion,
• a thickness of the spacer member in the stacking direction of the plurality of annular plates is smaller than or equal to that of the grommet plate,
• the number of the plates adjacent to the exhaust gas passage is equalized with that of the plates adjacent to the bolt holes,
• the fold-back portion of the grommet plate is formed by folding back the grommet plate toward an upstream side of an exhaust gas flow in the exhaust gas passage,
• the internal combustion engine is a diesel engine, and
• the parts are an exhaust manifold and a turbocharger, and the gasket is provided between the connection member of the exhaust manifold and the connection member of the turbocharger.
