²    Technical Characteristics

---

l   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.

l   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.

l   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.

l   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.

l   Safe:

Optional engine brake and exhaust brake,large braking power, and it is safer for going downward along a slope with heavy load;

l   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 .

l   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.

l   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.




²  Applicable Range:

---

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

Super heavy duty truck over 40 tons;
