Sinotruk Steyr engine is an engine brand under China National Heavy Duty Truck Group and has two major production bases in Hangzhou, Zhejiang and Zhangqiu, Shandong. SINOTRUK began to develop diesel engines in 1958. It is China earliest large-scale backbone enterprise specializing in the production of heavy-duty high-speed diesel engines and a national high-tech enterprise. In 1964, the company independently developed China first 6120 high-speed vehicle diesel engine, filling the gap in domestic heavy-duty diesel engine production.

For more horsepower and excellent fuel economy，SINOTRUK and German MAN cooperate to launch MAN series engines，and launched a series of trucks equipped with MAN engines：SITRAK.

SITRAK series heavy-duty trucks are localized products of joint-venture brand launched by SINOTRUK on the basis of the original MAN TG technology. With the B10 life of “1,500,000 km for engine and 1,000,000 km for transmission and axle”, SITRAK establishes a new standard for domestic premium heavy-duty trucks, and with the super-long warranty period of 2-year without mileage limitation, it sets up a new service benchmark for premium heavy-duty trucks

Four advantages

Economy：Super wide low fuel consumption and high torque range of MC11 (localized MAN D20) engine, high performance and high input torque of ZF transmission, high transmission efficiency and low gear ratio of MCY13 (MAN 13 t single reduction drive axle) drive axle, and low wind resistance of the cab allow the truck to maintain the tolerance of driving with low fuel consumption, and achieve the incomparable driving comfort.

Reliability：The original MAN TG technology, the same product design and production & assembly process, and the persistent enforcement of German standards from production conformity management, test validation to product release, as well as the application of important supporting parts from the original MAN supplier for the engine and the world top-class components for the chassis pull together to guarantee the high reliability of the complete vehicle.

Safety：The truck offers the active and passive safety of world top-class heavy-duty trucks. The cab meets the ECE R29 European truck cab strength standard; the steering column allows for deformation and energy absorption in a crash; front disk brake and rear drum brake as well as EVB are supplied as standard configuration, and ABS+ASR+EBL+TPM are optionally available; the powerful electronic management system (BCU+VCU) is equipped. These configurations assure the safety of occupants.

Comfort：High-performance gearshift operation and pneumatical steering wheel adjustment, large-span less-leaf spring, optimized full floating cab suspension, air seat with lumbar cushion, as well as wide framed berth allow Chinese users to enjoy the ride pleasure of the internationally most advanced heavy-duty truck.

Major assemblies

1. Cab. With MAN's TGA cab body, the cab is spacious, robust and streamlined, and up to ECE R29 European truck cab strength standard. Thanks to the state-of-the-art technology, this cab can compare with the car cab regarding ride comfort, and provide you the intelligent and safe drive & ride experience with the help of the intelligent information navigation system.

2. Engine. SINOTRUK exclusively introduces the world's most advanced MC11 (localized MAN D20) electronic control high-pressure common-rail engine. The vermicular graphite iron body has an ultra strong deformation resistance; the fuel injection system, a new generation Bosch product, has low specific fuel consumption of 186 kg/kw.h; the parts are highly integrated, and save the quantity of parts by 25 percent over similar engines in the world, reducing fault points greatly; the long B10 life of 1,500,000 km is up to the world most advanced standard for engines of heavy-duty trucks; the oil change interval of 60,000 km reduces vehicle cost substantially.

3. Transmission. ZF16S 16-speed transmission is adopted. Equipped with overgear, it features high first-gear speed ratio, light weight, good maneuverability, high efficiency, energy conservation and fuel saving and high economy, as well as a B10 life of 1,000,000 km.

4. Axle. MAN's MCY13 drive axle, a new-generation single reduction drive axle, is supplied with the SKF maintenance-free bearing unit as standard configuration. The brake shoe clearance is adjusted automatically and free of maintenance, and the lubrication system is equipped with an oil filter. With a B10 life of 1,000,000 km, the axle features high transmission efficiency, low noise and prominent oil conservation.

With products positioned to satisfy domestic customers' demands for substitutes for imported heavy-duty trucks and efforts made to comprehensively meet the rigorous requirements of domestic premium logistics for continuous and efficient operations through failure-free operations of top German quality. In the future, SITRAK is bound to bring a win-win mode of efficient and safe operations for domestic premium logistics customers.
