4BTA3.9-C110
Cummins
Reliable and Robust Power for Demanding Applications
The Cummins 4BTA3.9-C110 is a high-performance, heavy-duty diesel engine designed for durability and efficiency in the most challenging work environments. This four-cylinder, 3.9-liter powerplant delivers a dependable 82 kW (110 HP) of prime power. Built on Cummins' proven B-Series platform and manufactured by Dongfeng Cummins (DCEC), it combines advanced engineering with robust construction to offer a superior balance of power, fuel economy, and low total cost of ownership for a wide range of industrial, construction, and vehicular equipment.
The 4BTA3.9-C110 is engineered to be a versatile power source for medium-duty equipment across multiple sectors:
Construction Machinery: An ideal prime mover for excavators, wheel loaders, compactors, and mobile drilling rigs.
Commercial Vehicles: Powers medium-duty trucks, dump trucks, and specialized municipal vehicles like street sweepers and sprinklers.
Power Generation: Serves as a reliable engine for diesel generator sets, providing prime or standby electrical power.
Agricultural & Industrial Equipment: Used in agricultural machinery, industrial pumps, and various stationary power units.
Integrated Design for Maximum Reliability: The cylinder block and head employ an integrated design, which eliminates gaskets at critical joints. This innovative approach uses approximately 40% fewer parts than comparable engines, dramatically reducing potential failure points, preventing water and oil leaks, and enhancing overall durability.
Advanced Combustion & Fuel Efficiency: Equipped with a high-precision mechanical fuel injection system (Weifu PW pump) and an RSV governor for stable speed control. The engine utilizes advanced combustion technology, resulting in excellent fuel economy, lower operating costs, and strong power output.
Durable Engine Architecture for Long Life: Key components such as the camshaft and crankshaft are made from forged steel, and the cylinder block is designed for high strength and rigidity. The cylinder bore features a platform mesh honing design, which creates an optimal oil-retaining surface. This design, combined with advanced piston ring components, significantly reduces oil consumption and extends engine service life.
Turbocharged and Intercooled Performance: The engine is equipped with a turbocharger and a water-to-air intercooler (charge air cooler). This system forces more, denser air into the cylinders, resulting in increased power density, improved combustion efficiency, and lower emissions.
