YC6J Bus Series

Features For YC6J Series Bus Diesel Engine

Bosch E-control High Pressure Common Rail high injection pressure (1600 bar) for improved performance and fuel efficiency at every rpm.

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

Applying the computer software for performance analog calculation & combustion analysis so as to improve combustion conditions and make performance reach designed requirements completely.

Applying the finite element software for strict analysis of stressed deformation, as a result, major constructive design of the cylinder block, crankshaft, connecting rod and piston is made, characteristics of relevant parts & components are greatly improved, deformation is reduced to the minimum for meeting the requirement for stronger power and lower emission.

Adopting the platform checker technique for the cylinder liner synchronized with the international level.

Piston with internal oil cooling passages lowers the piston temperature and greatly improves itself in the working strength and reliability.

Adopting flexible design technique for the piston ring.

Adopting the upgraded HX40W turbocharger of Holset company featured by higher efficiency and longer service life.

Meeting the Euro-II, Euro-III and Euro-IV standard of emission.
