Timing cover for engine
A timing cover for an engine includes a plurality of dome-shaped embossed portions formed at positions of the timing cover that are most susceptible to vibration, based on an analysis of vibration modes of the timing cover.
1. A timing cover for an engine, comprising:
a connecting portion configured for connection to a cylinder block;
a shielding portion configured and dimensioned to cover a timing belt or a timing chain;
a first embossed portion at a central position of the shielding portion;
a second embossed portion at a position of the shielding portion located slantingly below the first embossed portion; and
a third embossed portion at a position of the shielding portion located above the first embossed portion.
2. The timing cover as set forth in claim 1 , wherein a first surface of each of the embossed portions is concave and a second surface of each of the embossed portions protrudes outwardly.
3. The timing cover as set forth in claim 1 , wherein the first embossed portion has a radius of about 35 mm and a height of about 4 mm.
4. The timing cover as set forth in claim 1 , wherein the second embossed portion has a radius of about 30 mm and a height of about 3 mm.
5. The timing cover as set forth in claim 1 , wherein the third embossed portion has a radius of about 30 mm and a height of about 5 mm.
6. The timing cover as set forth in claim 1 , further comprising a cover portion formed integrally with the shielding portion that covers a continuous variable valve timing device.
7. The timing cover as set forth in claim 1 , further comprising a support bracket formed integrally with the shielding portion that mounts an engine mount thereon.
8. The timing cover as set forth in claim 1 , wherein each of the embossed portions comprises a dome shape.
9. A timing cover for an engine, comprising:
a connecting portion configured for connection to a cylinder block;
a shielding portion configured and dimensioned to cover a timing belt or a timing chain; and
a plurality of embossed portions formed on the shielding portion;
wherein at least two of the embossed portions have different radii.
10. A timing cover for an engine, comprising:
a connecting portion configured for connection to a cylinder block;
a shielding portion configured and dimensioned to cover a timing belt or a timing chain; and
a plurality of embossed portions formed on the shielding portion;
wherein at least two of the embossed portions have different heights.
