NIGM26 series gas engine is the newest high-power gas engine designed by AVL company, the power range is 3000-4000kw.By adopting advanced parts production technology in global, NIGM26 series gas engine can ensure the quality of each engine parts.
1. Adopting multi-point injection, pre-combustion and main combustion double chamber rarefied combustion technology.
2. Adopting the world’s most advanced VTG booster (control type pressurization technology) and exhaust bypass type, can meet different load, different operating point supercharge match.
3. High power gas machine air-fuel ratio, speed and load control technology, makes the engine high efficient and low emission.
4. Adopting new engine control system, realized the engine knock detection, fire detection and other running status detection.
5. Adopting the mature technologies and products of international famous suppliers, to equip with safety protection technology such as engine oil mist detection.
6. Using the self-cleaning oil filter with metal filter element, can realize the automatic cleaning, without replacement filter.
