Comparison of Engine Basic Parameters
Displacement and Power
The 16V4000C01 series engines have a displacement of 64L, while the QSK 60 has a displacement of 60L. The larger displacement gives the 16V4000C01 series an advantage in power output, enabling it to provide more robust power for mining trucks and meet the operational requirements in complex mining conditions.Weight and Volume
In terms of weight, the 16V4000C01 engine weighs 7.1 tons when wet, and the QSK 60 Tier 1 weighs 8.6 tons. The 16V4000C01 is 15% lighter. In terms of dimensions, the 16V4000C01 is smaller than the QSK 60 in length, width, and height, with a 30% smaller volume. The lighter weight and smaller volume not only reduce the self – load of the mining truck but also enhance the vehicle’s maneuverability and flexibility to a certain extent.- Reduced tire wear / Increased load – carrying capacity
- Better fuel economy
- Low vibration; Low noise; Smoother engine operation

| Engine Wet Weight (tons) | 7.1 | 8.6 |
| Length (mm) | 2799 | 1371 |
| Width (mm) | 2929 | 1629 |
| Height (mm) | 1735 | 2316 |
Comparison of Fuel Economy
Fuel Consumption/Displacement
The 16V4000C01 series achieves more horsepower output with a larger displacement while consuming less fuel. For example, at a power of 2700bhp, the fuel consumption of the 16V4000C01 is 197g/kWh, while that of the QSK 60 is 206g/kWh.
Load Factor and Fuel Savings
When the load factor is 30%, the 2700 – horsepower 16V4000C01 engine saves 6.5 liters of fuel per hour compared to the QSK 60. If a fleet has 10 electric vehicles and operates 7000 hours a year, the annual fuel savings can be as high as 455,000 liters of diesel.
Comparison of Fuel Consumption under Different Loads
The following table allows us to more clearly see the differences in fuel consumption of the two engines under different loads:
| The load factor is 30% | |||||
|---|---|---|---|---|---|
| Load（%） | Time（%） | 16V4000 | QSK60 | ||
| BSFC | FC/hour | BSFC | FC/hour | ||
| (g/kWh) | (L) | (g/kWh) | (L) | ||
| 100 | 17 | 197* | 81,3 | 206* | 85 |
| 80 | 13 | 191 | 48,2 | 200 | 50,5 |
| 20 | 15 | 210 | 15,3 | 217 | 15,8 |
| 0 | 55 | ~260 | 5,5 | ~260 | 5,5 |
Note: *Data for EPA 1 certified version meeting EPA I emission standards. It can be clearly seen from the table data that the 16V4000C01 has a better fuel consumption performance than the QSK 60 under various load conditions.
Under a load factor of 30%, the overhaul intervals for the 2500hp engines 16V4000 and QSK60 are as follows:
- Theoretical overhaul interval: 16V4000 is 27,000-30,000 hours, while QSK60 is 20,000 hours.
- Actual overhaul interval: 16V4000 is 24,000-27,000 hours, while QSK60 is 15,000-20,000 hours.
The 16V4000C01 has an advantage in terms of low fuel consumption and also demonstrates a longer overhaul interval compared to the QSK60, making it a superior performer.
In terms of maintenance convenience, the comparison between the 16V 4000-2700hp and QSK 60-2700hp is as follows:
- Turbocharger: The 16V4000 uses a single-stage turbocharging system with 4 turbochargers, while the QSK60 uses a two-stage system with 8 turbochargers.
- Intercooler: The 16V4000 is equipped with 1 intercooler, whereas the QSK60 has 6 intercoolers.
- Overall layout design: The 16V4000 has a simple design, while the QSK60 is more complex.

Centrifugal Oil filters 500hrs maintenance
Centrifugal Oil filters processes approximately 10% of the oilflow provided by the engine pump before returning it directlyto the engine sump.
• As Contaminant particle enter the rotor they are subjected to a centrifugal force causing them to migrate radially outwards to the inner surface of the rotor wall where, over time they compact to form a dense cake.
• Service interval of the oil centrifuges: approximately 500h
• Oil-change interval remains as-is
Centrifugal Oil filters 500-1000hrs maintenance
• Instead of spin-on filters, optional automatic filters with two oil centrifuges as standard
• Self-cleaning, maintenance-free
• Service interval of the oil centrifuges: approximately 500-1,000h
• Oil-change interval remains as-is
Safety: lower risk of dirt penetrating to the clean oil side of the engine during the process of changing filters
