Piston / BA/BS3
This piston is built from high-strength aluminum alloy, offering excellent heat dissipation, durability, and resistance to thermal expansion. Its engineered crown shape optimizes air–fuel mixing and combustion efficiency, while the precision-machined skirt minimizes friction and ensures smooth movement inside the cylinder. Designed for BS3 engines, it maintains stable performance under heavy load and extended operating cycles.
By ensuring accurate compression and smooth reciprocating action, this piston contributes to improved fuel efficiency, reduced emissions, and enhanced engine longevity. Its robust construction supports consistent power output, reduced vibration, and reliable performance in demanding commercial vehicle applications.
Key Features
- High-strength aluminum alloy piston for BS3 engines
