Each cylinder has a cylinder head, four valve inlet and exhaust system, reliable work, convenient dis-assembly.
According to different occasions and requirements of the use, can choose electric pump or common rail pump. The built-in type oil cooler, safe and reliable.
Using the rear end of gear system (flywheel end) to reduce noise and improve the reliability. The water outlet pipe and the engine block are integral body, using double type thermostat.
Frame main bearing structure, the whole body rigidity is high, it is advantageous to improve the reliability and service life of the whole machine.
Double circulating cooling system, in which the cooler is arranged on the top of the flywheel housing, the structure is more compact.
Crankshaft belt pulley, water pump and generator by the multi wedge belt drive, the structure is simple.
