1.HOWO HEAVY DUTY TRUCK TECHNOLOGY PROMOTION
Adopting the most nowadays internatinally advanced engine and transmission assembly technique route, i.e. high torque common trail engine of broad speed belt+manual and automatic transmission (SMART SHIFT) + small speed ratio driving bridge. This brings chinese trucks into epochal automatic shift stage and makes the fuel consumption 3-5% lower than that of manual shift
1>. Oil Saving---two kinds of technology route (electric control common rail and EGR), engine characteristic performance curve
improvement, entire car optimizing assembly, AMT automatic transmission case, empty / full load switch, the latest streamline driving cab reducing wind resistance effectively, standard tractor reducing self weight by 200--500kg, and etc.
2>.Safety---disc brake, tubeless tire, exhaust valve brake technique application, rear axle brake shoe widening, and etc.
3>. Driving comfort---AMT automatic transmission case, quatre suspension driving cab, disc brake solving brake sway in case of over load, and etc
4>. Reliability---all the assembly has passed extremely harsh condition experiments and the verification of over 2 years in bad use conditon.
5>. Low application cost---large use quantity, complete service and accessory networks and low price.
