technique; lifespan of engine can achieve 800000 kilometers.
Meticulous application and most oil-saving place of engine always meets common working condition of
complete vehicle
Strengthen and injecting pressure of unit pump structure is twice as high as mechanical pump; power
take-off is efficient and fuel economy is better
Modular design, less complete vehicle parts, CAN line timely control of engine status and higher reliabilityApply international advanced 7 –level design and manufacturing precision, inbuilt unit pump structure,
single row gear train, crankcase high-mounted forced ring-cooling technique and echelon pre-heating
Unit pump is put inside the crankcase so that crankcase strengthen is high, not easy to break, unit pump
is not easy to be damaged and high pressure oil pipe doesn’t break
Many severe environment such as high-temperature, cold, highland, high-humidity and dusty wind are
considered at the beginning of design and it can easily work under severe working condition.
Unique unit pump oil supply system and has few requirements for fuel quality so that it can guarantee
reliability while adapting different oil quality in different areas.
Low noise with 1decibel lower than same product and can achieve standard without any supplementary
methods.
Provide international standard service based on DEUTZ and Volvo global service platformApply one pump per cylinder structure so that unit pump can be changed independently when there is
failure. Low maintenance cost and damage of one unit pump will not affect working in short time.
All maintaining points are on one side leading to short –time maintenance and low maintenance cost
