YUCAHI YC6MK350L-D20 Silent Diesel Generator Set

The YC6MK350L-D20 is a factory-enclosed silent diesel generator set combining Yuchai engine durability with effective acoustic treatment. Its soundproof canopy uses multi-layer absorption panels and baffled airflow to reduce noise to ≤94dB(A) at 7m, while allowing easy access for maintenance.

Key specs (official):

• Prime/standby: 200kW/250kVA – 220kW/275kVA

• Engine: YC6MK350L-D20, 6-cyl, 10.34L, turbocharged & intercooled

• Fuel consumption (prime): ≤195 g/kWh

• Control: Electronic regulation, 24V electric start

• Noise (enclosed): ≤94dB @7m

• Dimensions (L×W×H): ~3000×1100×1750mm; weight ~2300kg

This soundproof genset is ideal for hotels, hospitals, residential towers, and rental fleets requiring quiet, weather-protected, three-phase 50Hz power at 1500rpm. Meets non-road T3 emission standards.

Advanced Turbocharging & Intercooling:
The turbocharged and air-to-air intercooled induction system ensures consistent power output even at elevated ambient temperatures and moderate altitudes. By cooling compressed intake air before it enters the combustion chambers, the intercooler increases air density, enabling more complete fuel combustion — which translates directly to higher power density and lower exhaust emissions.

Electronic Fuel Control:
The YC6MK350L-D20 engine employs an electronic governor and fuel regulation system, delivering:

• Precise speed control under varying loads

• Smoother transient response during motor starting (pumps, elevators, air conditioners)

• Reduced frequency and voltage fluctuations

• Lower total harmonic distortion (THD) for sensitive electronic loads

Cold Start Performance:
The engine is capable of reliable cold starting at temperatures down to -25°C without additional aids, making the soundproof Yuchai generator suitable for installations in temperate and cold climates alike.

Altitude Capability:
The unit operates without power derating up to 1,000 meters above sea level. For installations at 1,000–2,500 meters, a modest power derating applies (typically 3–4% per 500 meters above 1,000m), which the electronic control system manages automatically to prevent overloading.
