| Parameter | Cummins QSB6.7 | Komatsu SAA6D107E-1 |
|---|---|---|
| Power Output | 260–275 HP (higher for versatile applications) | 175–220 HP (optimized for low-RPM torque) |
| Technology | Modular Common Rail System (MCRS) for precise fuel injection and quieter operation | High-torque design at low RPMs, ideal for sudden load demands |
| Noise Levels | Lower noise due to advanced electronic management | Slightly louder under high-intensity workloads |
| Weight | Lighter frame (~520 kg) for easier integration | Heavier construction for enhanced durability |
| Fuel Efficiency | Superior efficiency in varied conditions | Optimized for consistent heavy loads |
QSB6.7: Excels in light to medium-heavy-duty scenarios such as construction trucks, agricultural machinery, and commercial transport. Its adaptability suits mobile equipment like excavators and loaders, especially in urban or noise-sensitive areas.
SAA6D107E-1: Tailored for extreme conditions in mining and large-scale earthmoving, including Komatsu excavators (e.g., PC200LC series). Its high torque at low RPM ensures reliability in digging and material handling.
QSB6.7: Typically priced between 28,000–28,000–43,000, reflecting advanced technology and broader compatibility.
SAA6D107E-1: Ranges from 10,500–10,500–11,500 per unit, emphasizing cost-effectiveness for specific heavy equipment.
While both engines deliver durability, the QSB6.7 prioritizes versatility and efficiency for diverse industrial roles, whereas the SAA6D107E-1 focuses on raw power in niche heavy-duty applications. Pricing differences mirror their design priorities—innovation vs. rugged specialization.
