What is SinoTruk?

SinoTruk is the primary brand and foreign trade arm of China National Heavy Duty Truck Group (CNHTC). It is best known as China's first heavy-duty truck manufacturer, having produced the country's first heavy-duty truck, the Huanghe JN150, in 1960. Today, it is one of the world's largest heavy-duty truck manufacturers and has been the number one exporter of heavy trucks in China for over 18 consecutive years.

What is CNHTC?

CNHTC (China National Heavy Duty Truck Group Co., Ltd.) is the state-owned parent corporation that owns SinoTruk. It is an overarching enterprise group that oversees the manufacturing, development, and sales of heavy-duty trucks and related components through its various subsidiaries, including SinoTruk International.

What is the relationship between CNHTC and SinoTruk?

SinoTruk International is a wholly owned subsidiary of CNHTC. In simple terms, CNHTC is the parent company, and SinoTruk is its official international brand and export window. While CNHTC is a large industrial group, SinoTruk is the brand name under which its trucks (like HOWO and SITRAK) are sold globally.

What are the major products of SinoTruk?

SinoTruk offers a comprehensive range of commercial vehicles, including:

Heavy-Duty Trucks: Tractor heads, dump trucks, and cargo trucks for various applications like construction, logistics, and mining.
Key Brands: This includes the popular and high-value HOWO series, and the premium SITRAK series, which was developed in partnership with MAN to meet European quality standards.
New Energy Vehicles: SinoTruk is a leader in new energy, developing Battery Electric Vehicles (BEV), Hybrid Electric Vehicles (HEV), Fuel Cell Vehicles (FCV), and Hydrogen Internal Combustion Engines (HICE).
Special Purpose Vehicles: They also manufacture specialized vehicles like concrete mixers, oil tankers, and sprinklers through subsidiaries like the Jinan Special Automobile Co., Ltd.

What is SinoTruk Engine?

"SinoTruk Engine" refers to the range of engines developed and manufactured by SinoTruk for its vehicles. These include well-known series like the D10 and T10 (natural gas), and the more advanced MC series (like the MC11 and MC07H), which incorporate technology from international partnerships. These engines are designed for various emission standards (from Euro III to China VI) and applications.

What are the respective relationships between Sinotruk and MAN, and between Sinotruk and Steyr?

SinoTruk has a long history of technology transfer and partnership with leading European manufacturers:

SinoTruk and Steyr:

In the 1980s, SinoTruk successfully introduced the Steyr heavy-duty truck project from Austria. This partnership was foundational, and SinoTruk still builds upon the technology absorbed from Steyr, as seen in its D10 engine series, which evolved from the original Steyr design.

SinoTruk and MAN:

SinoTruk later formed a strategic cooperative agreement with German MAN. This partnership involved a comprehensive technology transfer of MAN's cab, chassis, axle, and engine technology. This collaboration led to the creation of the premium SITRAK brand and the high-performance MC-series engines, which are derived from MAN technology.

How is the quality of the SinoTruk engine?

The quality of SinoTruk engines is considered high and has been validated through international collaboration and rigorous testing.

Advanced Technology: Engines like the MC series are derived from German MAN technology and built using German production standards.
High Durability: The engines boast impressive lifespans. For example, the MC11 engine has a B10 life of 1.5 million kilometers, and the newer MC07H engine has a B10 life of 1 million kilometers.
Rigorous Testing: All engines undergo extensive bench testing and real-world trials in extreme high-temperature, cold, and high-altitude conditions to ensure reliability.

How is the fuel efficiency of the SinoTruk engine?

SinoTruk engines are engineered for excellent fuel economy.

Optimized Combustion: Engines like the D10 series have been optimized to significantly reduce fuel consumption in frequent working areas.
Low Specific Consumption: The MC11 engine features a very wide area of low fuel consumption, with a minimum specific fuel consumption as low as 186 g/kWh.
High Thermal Efficiency: The latest MC07H engine achieves a thermal efficiency of 47%, which allows it to save 5% more fuel compared to other brands under normal operating conditions.

Where can I buy the Steyr engine and the MAN engine produced in China?

While the original Steyr and MAN engines are no longer produced by their European namesakes in China, their technology lives on in SinoTruk's modern engine lineup.

For engines derived from Steyr technology, you would purchase the modern iterations, such as the D10 series engines, directly from SinoTruk or its authorized distributors.
For engines derived from MAN technology, you would purchase the MC series engines (like the MC11, MC07H) found in SinoTruk vehicles, particularly the SITRAK brand.

How to Purchase:

Official Distributors: Contact SinoTruk International or its network of over 300 global distributors to buy complete vehicles equipped with these engines.
Service Parts: Original spare parts for these engines can be purchased through SinoTruk's extensive global network of 700+ service and parts outlets.
Important Note: Be cautious of third-party sellers. For guaranteed authenticity and warranty, it is always best to purchase through SinoTruk's official channels.
