Description |
| 1 |
Toothed timing chain drive: |
7‑piece toothed timing‑chain drive, ensures stable valve‑train operation and low engine noise. |
| 2 |
Cylinder head |
One‑piece redesigned cylinder‑head with concise appearance. |
| 3 |
Hot‑assembled crankcase: |
Hot‑assembled crankcase with locking‑pin structure, reduces crankshaft axial‑play noise. |
| 4 |
Optimized thermal‑management structure: |
New cylinder‑head oil‑circuit layout, improves cooling air‑duct and reduces internal noise. |
| 5 |
Roller rocker arms: |
Reduce friction between camshaft and rocker; camshaft journal adopts ball bearing to cut power loss. |
| 6 |
Light‑weight piston & piston back‑cooling design: |
Reduce piston wear; prevent piston crown burn‑through and piston‑ring seizure. |
| 7 |
Dual DLC+PVD high‑performance piston‑rings: |
Superior wear‑resistance, long service‑life, resist oil‑burning. |
| 8 |
High‑torque starter motor: |
Braking torque up to 2.2 N·m for easy starting. |
| 9 |
Reinforced crankshaft bearing & shortened connecting rod: |
Reinforce bearing strength; reduce reciprocating inertial force and solve engine knocking. |
| 10 |
Optimized camshaft profile: |
Improve power and torque for better acceleration performance. |
| 11 |
High-Temperature Resistant Valve Material |
High‑temp 751‑grade exhaust valve for enhanced high‑temperature mechanical performance. |
| 12 |
Enlarged shift‑drum: |
Gentle groove curve for smoother gear‑shift action. |
| 13 |
Reinforced main & counter shaft: |
Strengthen gears for higher transmission reliability. |
| 14 |
Crankshaft offset technology: |
Reduce piston side‑thrust, improve combustion efficiency and fuel economy. |
