DCEC QSB3.9-C130-31 Industrial engine is a 4-cylinders in line, 3.9 liter four-strokes engine with 102mm bore and 120mm stroke. Equipped with Electrically Control High-pressure Common Rail, engine comes with turbocharger and Air- Air Intercooler.
Advanced design and sophisticated manufacturing, adapt to a variety of harsh working conditions, high strength, strong ability to work under heavy loads.
Cylinder block and cylinder head adopt integrated design, which eliminates the occurrence of engine water leakage and oil leakage. Parts are about 40% less than other similar engines, and the failure rate is greatly reduced.
Using forged steel camshaft and crankshaft, high-strength cylinder block design, multiple parts are cast on the cylinder block, with high rigidity, high pressure resistance, good reliability and longer service life.
The cylinder bore adopts a platform mesh honing design, and the perfect geometric structure effectively prevents oil leakage, and adopts advanced technology such as new piston ring components and gasket crimping molding to reduce oil loss.
Adopt Holset supercharger with integral wastegate valve, low speed response and strong power.
