4BT3.9-C90 Pump Engine

DCEC 4BT3.9-C90 pump drive engine is a 4-cylinders in line, 3.9 liter four-strokes engine with 102mm bore and 120mm stroke. Equipped with mechanical pump and RSV governor, engine comes with turbocharger. The prime power at 2900RPM of DCEC 4BT3.9-C90 pump drive engine is 66kW.

As part of EMAC, PumpMac provides abundant premium pump-driven power pack options, WPT PTO, Advance gearbox and pump head, as well as customized water pump set. We also have a set of NFPA20 standard engine power pack accessories including air intake shut-off valve, DC contactor, engine control panel, jacket water heater etc. We provide full life cycle services for all customers, from design to power system supply, from installation to commissioning, from after-sales service training to spare parts supply, from trouble shooting to overhaul technical support.

Advantages of 4BT3.9-C90 Pump Engine

1. Advanced design and sophisticated manufacturing, adapt to various harsh working conditions, high strength, strong ability to work under heavy loads.
2. CMS adopts advanced design and precise manufacturing technology, which reduces fuel consumption by 20% compared with similar domestic products.
3. Manufacturing process: The cylinder block and cylinder head adopt integrated design, which eliminates the occurrence of engine water leakage and oil leakage.
4. Good reliability The integrated design of cylinder block and cylinder head prevents water and oil leakage of the engine. There are 40% fewer parts than the same type of engine, and the failure rate is greatly reduced.
5. The three-stage fuel filter ensures a balanced level of particle dispersion, protects the main components of the fuel system, and maximizes the life of the engine.
6. The cylinder bore adopts a platform mesh honing design. The perfect geometric structure effectively prevents oil leakage, and the use of advanced technology such as new piston ring components and gasket crimping and molding reduces oil loss.
7.Forged steel camshafts and crankshafts, high-strength cylinders, cast on multiple cylinders, high rigidity, high pressure resistance, good reliability, and long service life.
