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
- Fuel injection system adopting BOSCH electronic control high pressure common rail
or DELPHI EUP, better working 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
Lower Fuel Consumption - Equipped with DELPHI EUP or BOSCH electronic control
high-pressure common rail fuel injection system, ensured quality of fuel atomization;
equipped with HONEYWELL GT series turbocharger featured by wider high efficiency-band
and quicker response; equipped with piston rings designed, reduced the oil consumption.
Stronger Power - 8.4L displacement and bigger torque reserve, max. torque
reaching 1280N.m, max. power reaching 330 horse powers, better capability for starting
to move and acceleration performance.
Lower Emission - passed certification of German TUV Company, meets Euro-II,
Euro-III and Euro-IV standards for emission.
Lower Noise - 4-valve per cylinder technology, lower noise, Optimized piston
profile and piston-to-cylinder clearance, lower the noise made by piston, noise
shields for key locations such as cylinder head cover, gear chamber, cylinder block
etc., equipped with the suspended & noise-reducing oil sump made of multilayer
vibration damping steel plate.
