Technical Characteristics

Economic:

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

Adopt electric-controlled closed-loop system and 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,

Adopt four-valve technology, with high inlet and exhaust efficiency;

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

Optional tail-gas heating function s reduce heating costs.


Reliable:

Use inter Euro first-class brand products for the key spare parts such as piston, piston ring, crank, bearing bush and high strength bolt;

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;

At present, it is most powerful natural gas engine at home with maximum displacement and power.


Comfortable:

Adopt Holland LMS vibration test system to make vibration 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;

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

Adopt ladder frame to increase structure rigidity of the whole set and reduce vibration ;

Precise dynamic calibration and smooth shift;

Optional cruise function, reduce driving strength.


Safe:

Optional engine brake and exhaust brake, large braking power, 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, four-valve technology and realize 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 6DN 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 PTO device, to meet the need of special vehicle use;

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

Applicable Range

13.7~25 meters road, tourism and urban passenger bus;

Super heavy duty truck over 40 tons;
