2. Product Core Features

The Yuchai YC4A205-D32 120kW 60Hz diesel generator set is a mainstream medium-power power generation equipment tailored for global 60Hz power frequency markets. Equipped with Yuchai’s mature YC4A series turbocharged intercooled engine and high-performance brushless self-excited alternator, this 150kVA diesel generator set balances strong power output, reliable operation and economical fuel consumption, and has always been a cost-effective choice for industrial and commercial power supply projects.

In terms of power performance, the unit adopts Bosch high-pressure common rail fuel injection technology with injection pressure up to 1600 bar, which achieves precise multi-point fuel injection and full fuel combustion under different load conditions. The matched low-inertia turbocharger ensures sufficient air intake, effectively improving power response and load carrying capacity. The 120kW continuous prime power and 132kW emergency standby power reserve fully meet the demands of long-term full-load operation and sudden power surge scenarios. It supports stable operation under 50%-80% conventional load for a long time, with fast transient speed regulation and no obvious voltage or frequency fluctuation during load switching, reaching industrial G3 power supply quality standard.

In terms of structural reliability and durability, the YC4A205-D32 diesel engine adopts high-strength alloy cast iron cylinder block and integrated cylinder head water outlet structure, which reduces sealing joints and effectively avoids common oil and water leakage faults of traditional generator sets. Equipped with Yuchai’s self-developed piston ring and valve oil seal sealing technology, the lubricating oil consumption is greatly reduced, and the daily maintenance cycle is longer than similar products. The whole machine adopts optimized vibration reduction and noise reduction structure, with low operation vibration and low noise, which can adapt to long-term unattended operation. Meanwhile, the unit can achieve reliable cold start at -20℃ and maintain rated power output without derating at an altitude below 2500 meters, with excellent environmental adaptability.

In terms of power generation safety and later maintenance, the supporting brushless self-excited alternator completely abandons the easily worn carbon brush and slip ring structure of brushed generators, greatly reducing equipment failure rate and daily maintenance costs. The whole winding adopts H-grade high-temperature resistant insulating materials, which can resist high-temperature aging and ensure stable power generation in high-temperature working environments. IP23 professional protection grade can effectively block external dust, floating debris and splash rainwater, protecting internal electrical components from damage. The built-in intelligent protection system supports low oil pressure alarm, high temperature protection, overload protection and over-speed protection, which can automatically shut down for fault protection and effectively extend the service life of the 150kVA diesel generator set.

In terms of operating economy, the optimized combustion system makes the full-load fuel consumption of the unit only 37.2L/H. Compared with other 120kW diesel generator sets of the same power level, it has obvious fuel-saving advantages. The long overhaul cycle of 12000 hours reduces the frequency of parts replacement and equipment maintenance, effectively lowering the overall operation cost for users and improving the economic benefit of long-term power supply.
