The 120KW diesel generator set uses the high-quality diesel engine YC6B180L-D20 produced by Yuchai as its power.

The main features of the Yuchai generator YC6B series:
1. Products developed by digesting and absorbing the consulting results of Germany's FEV; 2. The integral forged steel crankshaft, high-quality alloy cast iron cylinder head, and the body blank are all imported parts, with small size, light weight, low vibration, low noise, high reliability, and overhaul period greater than 12,000 hours; 3. The use of P-type high-pressure oil pump and P-type nozzle makes the combustion more complete, and the fuel consumption index is far better than that of domestic products with the same power;
4. The use of Yuchai's proprietary piston ring sealing technology and valve oil seal technology reduces the lubricating oil consumption by more than 20% compared with domestic products with the same power;
5. Ideal supporting power for 50~120KW generator sets.
