YC4EG

Model Characteristics (Product Advantages)

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
