Deep Dive into the Cummins PT Fuel System
Unlike modern common-rail systems that rely heavily on sensitive electronics, the NTA855-C335 utilizes the classic Cummins PT (Pressure-Time) Fuel System.
Mechanical Reliability in Harsh Environments
In remote mining sites or offshore drilling platforms, electronic sensors can become points of failure. The PT fuel system is primarily mechanical, making it:
- Fuel Quality Resilient: More tolerant of varying diesel qualities found in international markets.
- Field Serviceable: Can be adjusted and maintained by experienced mechanics without specialized diagnostic software.
Maintenance Tips for the PT Pump and Injectors
To maximize the lifespan of your NTA855-C335, HekoPower recommends a strict 250-hour interval for fuel filter replacement. Ensure that the STC (Step Timing Control) is periodically checked to maintain optimal injection timing during cold starts and high-load operations.
Application Analysis: Where the NTA855-C335 Excels
Through years of supplying engines to the global market, HekoPower has identified the most common high-performance applications for this 335HP unit.
Earthmoving and Mining: The Bulldozer Specialist
The NTA855-C335 is the primary choice for 220-320HP class bulldozers (such as the Shantui SD22 series). Its ability to handle sudden load surges without stalling makes it superior to smaller displacement engines.
Stationary Power: Industrial Power Packs
Beyond mobile machinery, this engine is frequently configured as a Cummins Industrial Power Unit. We supply these for:
- Large-scale water pumps for irrigation.
- Air compressors for mining ventilation.
- Hydraulic power packs for specialized offshore equipment.
Performance Comparison: NTA855-C335 vs. NTA855-C360
A common question our technical team receives is whether to opt for the 335HP or the 360HP variant.
- NTA855-C335: Optimized for continuous duty and fuel economy. Best for applications where the engine runs at 70-80% load for extended periods.
- NTA855-C360: Provides that extra 25HP needed for high-climb mining trucks or extreme-depth drilling, but with a slightly higher fuel consumption curve.
