Whether you need engine parts, transmission components, or chassis parts, we have you covered.
China National Heavy Duty Truck Group (Sinotruk) produces diesel engines with displacements of 11 liters and 13 liters. The following is an introduction to these engines:
MC11 Series (11 - liter)69
- Basic Information: The MC11 series diesel engines are the domestic - made versions of MAN D2066 engines. The "MC" represents MAN - technology diesel engines, where "11" indicates the engine displacement is 11 liters. For example, the model MC11.44 - 60 means it is a 11 - liter engine with a power of 440 horsepower, meeting the national VI emission standard, and adopting the EGR technology route.
- Performance Characteristics: These engines have a power output of up to 430 horsepower1. They feature high torque output, with a torque value of over 2000 N·m. This enables trucks to have strong power when starting, accelerating, and climbing slopes, meeting the power requirements of heavy - duty trucks and buses. They adopt advanced fuel injection technology, with a precise injection control system that ensures the full combustion of fuel, improving fuel economy and reducing emissions. In terms of reliability, the engine uses high - quality materials and advanced manufacturing processes. The crankcase is made of vermicular graphite cast iron (GJV450), which has high strength, good hardness, and stability, ensuring that the engine can operate for more than 1.5 million kilometers without deformation.
MC13 Series (13 - liter)
- Basic Information: The MC13 series diesel engines are based on the MAN D2676 engine technology6. They have a displacement of 12.5 liters and are mainly used in long - haul trucks and tractor - trailers1.
- Performance Characteristics: The MC13 series engines have a very high power output, reaching up to 540 horsepower, and a maximum torque of 2500 - 2700 N·m12. This allows trucks to maintain high - speed driving on highways and have excellent passing performance. In terms of fuel consumption, through the optimization of the fuel injection system and the combustion chamber, the engine achieves good fuel economy, and its low - fuel - consumption curve is wider, which can effectively reduce the overall fuel consumption of the vehicle. In addition, the engine is equipped with an advanced exhaust gas treatment system, which can meet the strict national and European emission standards. In terms of structure, the engine adopts a modular design, which not only reduces the number of parts by 25%, thus greatly reducing the failure rate of parts, but also facilitates maintenance and repair7. The cylinder block and cylinder head are made of high - strength materials, and the internal parts of the engine are strengthened, such as the nitriding treatment of the crankshaft surface and the inlay treatment of the valve seat ring, which improve the durability of the engine8.
