What is “bridge structure”?
Enhancement of rigidity
- Bridge shaped ribs are designed at both sides near the piston pin connection to improve rigidity.
- Utilizes A2618 material for superior high-temperature resistance and increased strength.
Weight reduction
- Optimized profile to shorten skirt height for less weight.
- Narrowing the skirt width on the anti-thrust side.
- Shortening the piston pin to reduce the weight of the pin boss and pin.
- Thinner wall and lighter weight by using high-strength materials.
Lower friction
- Two-layer fluoropolymer and molybdenum coating for friction reduction.
In consideration of effective sliding at high RPM, fluoroplastic coating is used for the inner layer and molybdenum coating for the outer layer.
