Why choose SINOTRUK?
High strength/ high rigidity/ long life block: vermicular cast iron body, similar strength cast steel, similar heat dissipation potential gray iron, strong anti-thermal deformation, high cost, can be adopted in few high end engines in the world due to its core technology.
1). Good economy: high-explosive pressure and optimized injection and combustion system, ensuring its low specific oil consumption at a wide range of sppds, Minimum specific oil consumption is 186/kwh.
2). Low nose: noise reaches the international level.
3). High-integration: volume of spare parts reduced 25% compared with the similar products in the world, highly reducing the failure points.
4). Long life of B10: reach the most advanced world level of heavy duty truck, 1.5 million km.
5). Long oil change interval: for Euro IV oil, the first oil change mileage( oil change interval) for the road vehicles since left factory shall be up to 100.000 km, for the oil selling bu Petrochina and Sinopec. it shall be up to 60.000 km, greatly reducing the cost.
HW series heavy yupe transmission is a new generation well-crafted product developed by SINOTRUK specially for the heavy duty truck, SINOTRUK own the independent intellectual property rights for it, with its unique structure home and aboard, its primary transmission adopts twin cuntershaft structure and auxiliary transmission adopts planetary deceleration structure, which make its bearing capacity stronger and its structure more reliable. The integrated small housing design allows legible gear and flexible gear shift.
Presently, this type of transmission is applied to be engine for the heavy duty truck which power range is 336--420 ps, it is the first choice for the domestic heavy duty truck.
