Diesel engine

6-cylinderdirect fuel injectionfor the construction industry

High reliability, excellent economical efficiency, low vibration & noise and good adaptability 　　Weichai Power is the general application engine manufacturer with world's advanced level, and is also the largest domestic power supplier for construction machinery. According to different requirements of different vehicles from the vehicle manufacturers and improve the product performance further, the engines adopt new high-level profile of Stage II. The power range is from 125Ps to 400Ps and is the ideal power for 3t - 9t loaders. 　　1.Fuel-efficient technology 　　(1)Low speed matching technology 　　1)Low-speed diesel engine optimization - rated speed reduction and ultra-high torque output 　　2)Torque converter optimization – bring out the best performance of the low-speed diesel 　　3)Gearbox adjustment - vehicle running speed improvement 　　4)Hydraulic system adjustment - loading efficiency improvement 　　Advantages of low speed： 　　1)Mechanical loss reduction and mechanical efficiency improvement 　　2)Mechanical wear reduction and engine life extension 　　3)Speed reduction and great engine noise reduction 　　4)Reasonable power system matching and fuel consumption reduction 　　(2)Landking II generation - Electromagnetic fan 　　When the test ambient temperature is about 23℃, loaders using an electromagnetic fan has slight production efficiency increase compared to loaders without an electromagnetic fan. And the fuel consumption is also slightly lower, saving the fuel by 4.03% on average and by 4.69% for the highest. If the ambient temperature is further reduced, the fuel efficiency will be even higher.
