1. Increased stroke / bore ratio: 3:1
2. Reduced SFOC about 6 %.
3. Improved propeller efficiency about 2 %.
4. Simple liner construction, and low cost.
5. Thin walled liner and improved jacket cooling efficiency.
6. Simple cooling water sealing.
7. No temperature gradients across scavenge ports and exhaust valve.
8. Shorter piston skirt.
9. With uniflow scavenging, improved scavenge efficiency
