6.3 Fuel Recommendation

Natural Gas: Pipeline natural gas with a heating value of 36MJ/m³ (or above.)
，
CH
4
＞
80%.

Gas quality requirements (measure within 1 meter of engine gas inlet)
：
Into the engine intake pressure is (3~5) kPa (after the pressure regulator), customers can
choose their own regulator.
Pressure change rate ≤1kPa/min;
H
2
S≤20mg/Nm³;
Im
purity particle size≤5μm;
Impurity content≤30mg/Nm³;
Ammonia≤20mg/m³;
Tar content≤50mg/m³;
Moisture content≤20mg/Nm³.

If the fuel is not used as specified, there will be some loss of engine power, and emissions
may not meet the non-road
Ⅲ
stage regulations. Higher heating value cannot improve
the power of the engine
，
but the lower heating value will lead to loss of the engines power.
If the gas with the heating value is under 20.5MJ/m³ and the content of CH
4
is under 60%
will cause the engine cannot work.
