Powerful Heavy Truck Heart – China’s Most Fuel-efficient Engine

The newly designed Sinotruk D12 series engine is currently the most representative heavy truck engine in China, with a power range of 340-460Ps. China National Heavy Duty Truck has developed a series of new technologies and achieved obvious differentiated results, making the D12 engine have good maneuverability. The large displacement and high power enable the vehicle to obtain power from low idle speed, and at the same time, its wide speed range enables the whole machine to obtain constant power value and maximum torque value. This characteristic determines the perfect fuel economy and drivability of the D12 engine. Exquisite manufacturing and assembly processes make the engine overhaul mileage more than 1 million kilometers. Effectively solve the problem of high after-sales failure of other similar models in China. In order to meet the needs of different customers, Sinotruk also customized D10 series engines (270PS-380PS) for HOWO-A7. The D10 series engine adopts the domestic first technology of independent innovation – supercharger mid-position. The application of this technology has brought substantial changes to the intake and exhaust system, with smooth intake and simple exhaust, making the vehicle’s “lung” function more prominent and fuel economy better. Both D10 and D12 engines meet China 3 emission standards, and have the technical potential of China 4 and China 5.
