B190-33 Automotive Engine

DCEC 6BTA5.9-G3 engine is a 6-cylinders in line engine, which is a 5.9 liter four-strokes B series generator drive engine with 102mm bore and 120mm stroke. Equipped with BYC PB pump and GAC electronic governor fuel system, engine comes with turbocharger and Water-Air Intercooler. Standby power is 132 KW at engine 2000 RPM

Advantages of B 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.
