Diesel Engine Yuchai Bus Engine YC6M

Product:     Diesel Engine Yuchai Bus Engine YC6M   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 – 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 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   Main Technical Parameters
