NT855 engine product introduction
NT855 is a classic inline six-cylinder, four-stroke diesel engine, known for its large displacement, high reliability and ultra-long life. It was one of the main models of heavy machinery power in the mid-to-late 20th century. The engine is widely used in engineering machinery, heavy trucks, generator sets, ship power and other fields, and is still in service in some old equipment.
Core features
Super durability
Adopting cast iron cylinder block + forged steel crankshaft, the structure is strong and the design life is 20,000+ hours (industrial application).
Suitable for high load and harsh working conditions (such as mines and oil fields).
Low maintenance cost
PT fuel system has a simple structure, convenient maintenance and strong adaptability to oil products.
Maintenance cycle is 500 hours (industrial version), and filters and injectors are easy to replace.
Wide adaptability
Can match mechanical pump/electronic control system to meet different emission requirements (Tier 1 to Tier 3).
Flexible installation in horizontal or vertical positions, compatible with a variety of equipment such as construction machinery, power generation, and ships.
Classic power inheritance
The subsequent upgrade model is QSM11 (electronic common rail), but NT855 is still popular in the second-hand market because of its durability.
Main application areas
Industry Typical equipment Common models
Engineering machinery Loader (ZL50C), bulldozer (SD22) NT855-C/D
Mining truck HD465, 777 (old model) NT855-E/NTA855-P
Generator set 500-1000 kW backup power supply NT855-G
Ship power Inland tugboat, fishing boat NTA855-M
vehicle Armored engineering vehicle, heavy transport vehicle NTA855-P (high torque version)
Model classification and horsepower comparison
NT855 is divided into three series according to intake method and power:
(1) Naturally aspirated (N855)
Power: 180-290 HP
Application: low-load fixed equipment, such as agricultural machinery, old generators.
(2) Turbocharger (NT855)
Power: 250-400 HP
Representative models:
NT855-C (250 HP): loader
NT855-D (290 HP): bulldozer
NT855-G (350 HP): generator set
(3) Turbocharger + intercooler (NTA855)
Power: 350-450 HP
Representative models:
NTA855-M (400 HP): ship
NTA855-P (450 HP): mining truck, special vehicle
5. Technological evolution and alternative models
Early version (1960s-1990s): mechanical pump (PT system), Tier 1 emission.
Later upgrade (after 1990s): some models introduced electronic control to meet Tier 2/Tier 3.
Modern alternative: QSM11 (electronic common rail, displacement 10.8L, Tier 4 Final).
6. FAQ
Q1: Has the NT855 engine been discontinued?
→ Yes, the NT855 has been discontinued, but the second-hand market and stock equipment are still widely used, and spare parts are in sufficient supply.
Q2: What is the fuel consumption of the NT855?
→ Depending on the load:
Engineering machinery version: about 180-220 g/kWh
Generator optimized version: 160-190 g/kWh
Q3: Can the electronic fuel system be modified?
→ Yes, but the high-pressure pump, ECU and injector need to be replaced, which is costly. It is usually more economical to directly replace it with QSM11.
Summary
NT855 is an "industrial legend" in the field of diesel engines. With its simple and reliable, easy maintenance and long life, it has dominated the heavy-duty field. Although the technology has been gradually replaced by electronically controlled models, it can still be seen operating stably in harsh working conditions such as mines and ships.
