Advantages of SINOTRUK MC07 Automotive Engine
SUPERIOR STRUCTURAL STRENGTH: Topology-optimized lightweight high-strength cylinder block can withstand peak cylinder pressure up to 24 MPa; 4mm wall thickness proprietary manufacturing technology enhances cooling of critical combustion components, reducing thermal load.
EXCELLENT FUEL ECONOMY: Advanced parametric stepped combustion chamber design combined with DOE-optimized combustion system and 1800 bar high-pressure common rail (Bosch) with large-flow injectors. Minimum BSFC as low as 180 g/kWh – among the best in its class.
HIGH POWER DENSITY: Based on MAN D08 technology transfer, rated power up to 254 kW (345 HP) with maximum torque 1400 N·m at 1200–1700 RPM, delivering outstanding low-speed torque and rapid throttle response for heavy-duty truck applications.
OUTSTANDING ENVIRONMENTAL ADAPTABILITY: ECU built-in high-altitude adaptive learning system ensures stable power output above 70% rated power at altitudes up to 4,850 m. Direct start capability at –25°C without auxiliary equipment; reliable cold start down to –43°C with auxiliary preheating. Full rated power output maintained at ambient temperatures up to 45°C.
MODULAR DESIGN FOR EASY MAINTENANCE: Highly integrated auxiliary modules including oil filter/cooler module, fuel filter/hand pump module, and active oil-driven oil-gas separator reduce sealing failure points and extend service intervals significantly.
INTELLIGENT ELECTRONIC CONTROL: New-generation Bosch MD1 platform ECU with proportional valve or pulse valve boost control, enabling precise fuel injection and significantly reducing emissions while optimizing combustion efficiency to meet China VI standards.
PROVEN MANUFACTURING QUALITY: Produced at SinoTruk’s world-class Hangzhou facility using German HELLER machining lines and KW/HWS casting equipment. Intelligent flexible assembly lines with MES full-traceability data management ensure consistent product quality.

FAQ
What emission standard does the SinoTruk MC07 comply with?
The MC07-61 series complies with China VI emission standards using Hi-SCR (High-efficiency Selective Catalytic Reduction) aftertreatment technology, meeting the latest Chinese heavy-duty vehicle emission regulations.
What is the difference between MC07 and MC07H?
The MC07H features a longer stroke (134 mm vs 125 mm) and larger displacement (7.36L vs 6.87L), delivering higher torque output (up to 1400 N·m for MC07H.35-61 vs 1212 N·m for MC07.29-61) for more demanding applications, while maintaining the same 2200 RPM rated speed platform.
Can the MC07 engine operate at high altitude?
Yes. The MC07 ECU features a built-in high-altitude adaptive learning system that ensures the engine can output over 70% of its rated power at altitudes up to 4,850 m. Standard models experience no power derating up to 2,000 m, and select models maintain full rated power up to 3,500 m.
What is the warranty policy?
Standard warranty covers 2 years or 100,000 km under normal operating conditions. Extended warranty packages are available. Please contact our sales team for details.
Are spare parts readily available?
