Technical Characteristics

Fuel Efficient:

The running cost in terms of same mileage is greatly in comparison tp diesel engine;

Adopt electric-controlled closed-loop system and special natural gas mixer to improve charging efficiency, with precise control of burning process to realize stable operation of lean bum and gas consumption is lower;

The main parts are universal for 6DL diesel engine, spark plug and ignition coil have long service life and maintenance cost is low;

Optional tail-gas heating functions reduce heating costs.


Reliable:

Adopt inter Euro first-class brand products for motion friction pair, fuel system, ignition coil, spark plug and other key parts;

Adopt the inter Euro mainstream electric-controlled natural gas system, with mature technology.


Powerful:

Adopt supercharged inter cooling technology, with large power and large torque at low speed.


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;

Low explosion pressure, soft running and low noise;

Precise dynamic calibration makes the whole vehicle smooth in shifting;

Optional cruise function, reduce driving strength.


Safe:

Optional exhaust braking device and it is safer for going downward along a slope with heavy load;


Environment-friendly:

Natural gas fuel properties fulfill low carbon and smoke-free emission;

Adopt electric-controlled closed-loop system + exhaust after treatment technology to achieve  low HC, NO x emission.


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;

The appearance layout is similar to 6DF diesel engine, with good inheritance, adopting after treatment device with silencers.  Gas system components have good integration, with convenient matching with whole vehicle.


Personal Design:

Optional two kinds of states of CNG and LNG.

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

Applicable Range

8.9~11 meters road,tourism and urban passenger bus;
