Products
1. Reliability
Passed the road adaptability test of about 2.6 million km (including high-temperature test, alpine-cold test and plateau test) and the reliability bench test of about 30,000 hours
Additional stiffening ribs arranged outside the engine block and a cambered structure of the skirt, ensuring higher strength of the engine block and meeting the requirements of high blasting pressure
Use of a crankshaft made of 42CrMo forged steel, ensuring high strength and toughness, and strong explosion pressure resistance; optimized internal oil passage, improving the lubrication effect and achieving reliable power output
2. Fuel economy
Application of a mature four-valve structure and Yuchai's patented combustion technology, achieving a minimum fuel consumption of 198 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%
3. Safety
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
4. Comfort
Use of a noise reduction gear chamber with internal stiffeners, a noise-reduction cast aluminum cylinder head cover, and a noise-reduction oil pan
Application of pilot injection control, intelligent idle speed control and other electronic control technologies, effectively reducing engine vibration and noise
