¤  Technical Characteristics


●  Fuel Efficient:

Higher injection pressure,higher atomization rate,and more sufficient in combustion;

Independent  R & D on design of combustion chamber,intake and exhaust passage, three holes position on cylinder cover, and other technology,diesel engine inlet and exhaust system as well as combustion system are in the leading position at home;

●  Reliable:

Cylinder body,cylinder cover,crankshaft,connecting rod and other key parts are made CAD / CAE calculation,analysis ,optimization, reliable and durable;

● Comfortable:

Adopt Holland LMS vibration test system to make vibration testing optimization on the whole set ,providing NVH support optimization for forming a complete  set ,with small  vibration and low noise;

Adopt helical gear transmission to improve transmission stability and reduce mechanical noise;

Optional cruise function ,reduce driving strength;

Precise dynamic calibration makes the whole vehicle smooth in shifting;

● Safe:

It is optional to install OBD fault detection for real-time fault alert.

● Optimization of whole set:

Adopt Austria AVL vehicle power transmission system simulation software to calculate,analyze & compare,test and evaluate for the whole vehicle matching ,and the whole vehicle has powerful matching and better economical efficiency;

● Personal Design:

Optional electric-controlled common rail,electronic unit pump or mechanical pump + EGR and other multi technigues, to achieve Euro Ⅲ emission standard;

Optional air conditioning,power steering,oil or gas brake;

Optional GPS system,with vehicle management ,real-time control,vehicle security ,remote diagnosis and other functions;

Optional remote throttle,speed limits,deputy shutdown,CAN instrument and other functions.

¤    Applicable Range:


6~7.2meters road,tourism and urban passenger bus;
