China Yuchai - YC4G Series 170-220 HP Diesel Engine for vehicles

Features And Benefits

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