Agricultural multi cylinder diesel engine was newly developed by Changfa, which is specially used for tractor, harvester, sprayer and other machinery. It is reliable and durable, and cover power range from 25 to 120 horsepower, with complete configuration, easy installation, it is the ideal power for small and medium-sized agricultural machine.
Advantages:
It adopts domestic mature fuel system to realize accurate control of fuel injection quantity, full combustion and low emission. It belongs to the technical route recommended by the Ministry of environmental protection and can be priorly listed in the national environmental protection subsidy catalogue.
Through the finite element analysis, strength the design of engine body,cylinder cover and transmission gear to improve the reliability of key parts; the overload assessment is carried out on the output gear of front-end hydraulic pump to ensure the reliability, and the effective life of the whole machine is increased by 30%.
The non road electronic unit pump fuel system can be disassembled dependantly, easy to repair, it can reduce the maintenance costs for users, and meet the needs of agricultural customers.
The whole series adopts two-stage filtration system, coarse filtration and fine filtration. The filtration accuracy and efficiency are up to 99%. The adaptability of oil is equivalent to mechanical pump, superior to common rail system and suitable for agricultural machine.
Use value:
Long service life, full combustion, low emission, better economic type.
Meeting the requirements of non road national level III with upgrading potential of national level IV.
Good environmental adaptability, professional installation interface, it is the ideal power for agricultural power.
Mature design, easy maintenance, low cost.
