NIGM-165S Series Dual Fuel Engine have been widely used in Chinese oil field and the CNOOC platform.

NIGM-165S Series Dual Fuel Engine is originally of 396 series military engine of the Germany MTU company,and it develops on the basis of GTI Dual Fuel System of America Altronic Co. The global fuel alternative rate in theory is from 50% to 70%,and our products could reach to 65.4%-69% for different kinds of fuel.Our exhaust smoke reduces more than 70%. Single engine could save 324,6048RMB fuel cost,and it is the more environmentally friendly,energy-saving, low cost original power engine.Besides, it fully realizes 0 second switch for high speed engine smooth running when instant gas cut off.

Our products have been widely used in Chinese oil field and the CNOOC platform.
