Technical Overview of Cummins Genuine New NTA855-C280 Engine Motor for Bulldozer

The Cummins NTA855-C280 engine is a high - performance power unit designed specifically for bulldozers, delivering reliable and robust operation in demanding construction environments.

1. Engine Specifications

Engine Model: NTA855 - C280

Engine Type: In - line 6 - cylinder, 4 - stroke diesel engine

Displacement: 14 liters. The large displacement allows for significant air and fuel intake, contributing to high power output.

Bore * Stroke: 140 * 152 mm. This bore - stroke combination is optimized for efficient combustion and torque generation.

Aspiration: Turbocharged & after - cooled. The turbocharger compresses the incoming air, increasing its density and enabling more fuel to be burned, thus enhancing power. The after - cooler then cools the compressed air, further improving combustion efficiency.

Compression Ratio: 14.5:1. A relatively high compression ratio ensures effective ignition of the fuel - air mixture without the need for a spark plug, typical of diesel engines.

Fuel System: Direct injection PT (Pressure - Time) fuel system. The PT fuel system precisely meters the fuel based on pressure and time, providing accurate fuel delivery for optimal performance and fuel economy.

2. Performance Characteristics

Rated Power: 209 kW (280 hp) at 2100 rpm. This power rating enables the bulldozer to handle heavy - duty tasks such as moving large volumes of earth, pushing materials, and operating in rough terrains.

Max Torque: 1139 N.m at 1500 rpm. High torque at low engine speeds is crucial for bulldozers, as it provides the necessary pulling and pushing force required for operations like ripping through hard - packed soil or moving large boulders.

Fuel Consumption: Approximately 210 g/kW.h at rated power. The advanced fuel injection system and efficient combustion process contribute to a relatively good fuel consumption rate, helping to reduce operating costs over time.

3. Engine Design Features

Crankshaft and Connecting Rod: The engine features a robust and fully balanced crankshaft design. This balance ensures smooth rotation, reducing vibration and increasing the overall strength of the engine. The steel piston crown with an oil gallery and aluminum skirts provides better durability and low oil consumption. The oil gallery in the piston crown helps in cooling the piston, while the aluminum skirts reduce weight and friction.

Lubrication System: A dual spin - on filter is used to effectively separate impurities above 10um. The low - pressure (220 - 310 kPa) and steady - temperature (100 - 120 °C) lubrication system reduces the auxiliary power wasted by the lubricating oil pump, ensuring efficient engine operation.

Cooling System: A high - flux water pump and a special channel design provide effective cooling for the engine. The spin - in water filter keeps the coolant clean and maintains its normal acidity, preventing corrosion and ensuring long - term reliable cooling performance.

Exhaust System: Advanced Holset turbocharger and water - air after - cooler technology, along with a pulse exhaust manifold, reduce exhaust temperature. This not only improves the durability of the exhaust system but also contributes to excellent fuel consumption and emission performance.

4. Starting and Electrical System

Starting: The engine is equipped with a 24V electric start system, providing reliable and quick starting in various operating conditions.

Electrical System: The electrical system is designed to support the engine's operation, including powering the fuel injection system, ignition (in the case of glow plugs for cold - start assistance in diesel engines), and other electrical components.

5. Applications in Bulldozers

The Cummins NTA855 - C280 engine is widely used in bulldozers due to its high power - to - weight ratio, excellent torque characteristics, and reliability. It can power medium - to - large - sized bulldozers, enabling them to perform tasks such as land clearing, grading, and heavy - load pushing with ease. The engine's ability to operate under extreme conditions, including high - temperature and high - altitude environments, makes it a preferred choice for construction projects around the world.

In conclusion, the Cummins NTA855 - C280 engine is a well - engineered powerplant that offers high performance, reliability, and fuel efficiency for bulldozer applications. Its advanced design features and robust construction make it suitable for the most demanding construction operations.
