YC6M Bus Series

Features for YC6M Series Bus Diesel Engine

4-Valve Per Cylinder Technology-centered injector, more even atomization and more complete combustion, improved airflow, higher efficiency of air intake and exhaust, lower fuel consumption and better for environmental protection.

Full-Authority Electronic Controls ¨C Optimize engine performance and provide seamless integration with other components, advanced diagnostics, plus a complete set of programming options.

High-performance Configuration:

  • 4-valve per cylinder technology, higher efficiency of air intake and exhaust
  • BOSCH high-pressure common rail technology, stronger capability
  • Honeywell GT turbo-charger, optimized performance at high speeds
  • Oil sump made of multilayer vibration-damping steel plate, lower noise
  • Equipped with German Mahle pistons, more reliable operation

Stronger Power-10L displacement and Max. torque reaching 1680N.m,Maximum power 390HP, optimized performance at high speeds, quick response for acceleration.

Lower emission-passed certification of both German TUV,meets Euro-II, Euro-III and Euro-IV standard of emission.

Lower Noise-Optimized piston profile and piston-to-cylinder clearance, lower the noise made by piston, adopting rear-positioned timing gear chamber and advanced point-line gear-meshing technology, lower the mechanical noise of the transmission system.
