Features And Benefits
Full-Authority Electronic Controls ¨C Optimize engine performance and provide seamless integration with other components, advanced diagnostics, plus a complete set of programming options.
¡ñ Adopting CAD/UG 3D technology, critical component after CAE technical analysis, high reliability
¡ñ Adopting German FEV technology, further strengthened cylinder block , reduced vibration.
¡ñ Adopting forged steel crankshaft, dry type cylinder liner, German Mahler special piston, which improve the engine in reliability.
¡ñ Matching optimized Garrett turbocharger greatly increases the torque at lower speeds.
¡ñ Adopting high efficiency filter separating water from the fuel improves the injection system in reliability.
¡ñ Optimized piston-cylinder bore clearance ensures small quantity of compression blow-by and lower oil consumption.
¡ñ Optimized crankshaft torsional damper lowers the shafting torsional vibration and extends the service life of shafting.
¡ñOptional dual spindle balance mechanism to be used for balancing the secondary to-and-fro inertial moment further lowers vibration and noise level.
¡ñ Up to Euro-II or Euro-III standard of emission
¡ñ Human-oriented design, high interchangeability, excellent approachability, easier maintenance.
