ISZ520-41 Automotive Engine

BFCEC ISF3.8s3154 automotive engine is a 4-cylinders in line, 3.76 liter four-strokes engine with 102mm bore and 115mm stroke. Equipped with Electrically Control High-pressure Common Rail, engine comes with Turbocharged and Air- Air intercooler. The prime power at 2600RPM of BFCEC  ISF3.8s3154 automotive engine is 115kW.

As part of EMAC, DuraMac provides complete powertrain that integrated with BFCEC engine, Fast-Eaton clutch, FAST-CAT transmission, Dongfeng-DANA axle and Komman air suspension, while the electrification of automobile is the certain future, Duramac also get involved with EV powertrain system. 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 ISF3.8 Automotive Engine

1. The cylinder bore adopts a platform mesh honing design, the perfect geometric structure effectively prevents oil leakage, and adopts advanced technologies such as new piston ring components and gasket crimping molding to reduce oil loss.
2. The cylinder block and cylinder head adopt integrated design, which eliminates the occurrence of engine water leakage and oil leakage. The parts are about 40% less than other similar engines, and the failure rate is greatly reduced.
3. Forged steel camshaft and crankshaft, high-strength cylinder block design, multiple parts cast on the cylinder block, high rigidity, high pressure resistance, good reliability, and longer service life.
