Products
Design of a high-strength gantry structure, ensuring a solid and reliable engine block
Reliability development in strict accordance with FEV's mechanical development programs
Stepped connecting rod design, ensuring a higher pressure bearing capacity at the connecting rod small end and improving the reliability
Use of a 2-hole piston with an internal cooling oil passage
Application of comprehensive simulation calculation (CAE analysis), ensuring the reliability of parts
Application of an advanced high pressure common rail (HPCR) fuel system and Yuchai's patented in-cylinder combustion technology, effectively improving the engine power and torque, and maximizing the load-carrying capacity of vehicles
Application of Yuchai's patented efficient combustion technology, achieving a minimum fuel consumption of 193 g/kwh
Road spectrum collection and fine calibration according to market segment and applications, ensuring fuel economy
Use of an intelligent fuel-saving switch: The position switch is adjusted according to the real-time load, allowing the vehicle to operate in the economical range all the time, thus reducing the fuel consumption by at least 10%
Torque at 900 rpm: 820 N.m; maximum torque: 950 N.m
23% higher than the low-speed torque of competitors and 6% higher than the maximum torque of competitors, ensuring faster starting, easier overtaking and more efficient operation
Maximum speed control — be able to protect the engine from any damage due to excessive mechanical stress or thermal load
Limp home — be able to reduce the power in case of a fault in the electronic control system, ensuring that the vehicle can be driven to the maintenance station nearby
Low oil pressure protection — real-time monitoring and automatic fault diagnosis, achieving higher driving safety
Thermal protection — automatic torque limiting and overheating protection
Use of a thickened gear chamber cover, putting to an end to deformation
Change of the U-bolt groove structure between the cylinder heads of cylinders 3 and 4 to a new pressing block, improving the reliability of cylinder gasket
Heat shield of exhaust pipe and heat shield of turbocharger
Optimized air compressor speed ratio, reducing vibration
Use of a three-section exhaust pipe and a double-grid connecting rod bearing bush, achieving an increase in explosion pressure resistance by 15% and stronger deformation resistance
