The Yuchai YC6B180L-D20 100kW/125kVA diesel generator set is a high-performance six-cylinder industrial power generation equipment tailored for medium and high-power continuous power supply scenarios. As a mainstream 125kVA Yuchai diesel generator widely used in industrial standby and engineering temporary power supply fields, this unit adopts the original YC6B180L-D20 six-cylinder turbocharged intercooled diesel engine. Compared with four-cylinder generator sets of the same power level, it delivers stronger torque output, more sufficient power reserve and more stable continuous operation performance, effectively solving the problems of weak surge resistance and easy power attenuation of conventional 100kW diesel generator sets under long-term high-load working conditions.
In terms of power supply stability, the unit supports 100kW long-term uninterrupted prime power operation and 110kW short-time emergency standby power output. With 116kW rated engine power reserve, it retains abundant power margin to cope with instantaneous startup impact of multiple high-power equipment and frequent load switching. Whether working stably at rated load for 24 hours or undertaking sudden overload emergency power supply, it always maintains standard 50Hz frequency and three-phase 380V balanced voltage output without obvious fluctuation or drift. Matched with industrial-grade brushless self-excited pure copper alternator and high-precision AVR automatic voltage regulator, the current output is ultra-stable. Equipped with H-grade high-temperature resistant insulation structure, the alternator can resist heat aging and insulation breakdown caused by long-duration high-load operation, providing safe and reliable power guarantee for industrial precision instruments and large mechanical equipment.
Low maintenance cost and excellent environmental adaptability are the core practical advantages of this Yuchai 100kW standby diesel generator set. The brushless self-excited excitation design completely cancels wearable carbon brush components, realizing long-term maintenance-free daily operation, greatly reducing on-site equipment inspection workload and later operational investment. The engine adopts wet-type cylinder sleeve structure and high-rigidity alloy iron body, which features small vibration, low noise and convenient partial disassembly and maintenance, avoiding overall engine dismantling and lowering maintenance difficulty. The IP23 professional dustproof and rainproof protection grade can effectively block outdoor dust, debris and splashing rainwater, adapting to open-air placement and harsh construction site environments, and is very suitable for unattended factory standby power and outdoor field off-grid power supply.
In terms of fuel economy and operational reliability, the YC6B180L-D20 engine adopts optimized turbocharged intercooled air intake technology and precision direct injection combustion system, making fuel combustion more sufficient and uniform. The full-load fuel consumption is stably controlled at 28.5L/H, with stable fuel-saving performance in variable-load working conditions, effectively controlling long-term power generation operating costs. The six-cylinder in-line water-cooled structure runs more smoothly than four-cylinder units, with lower mechanical vibration and wear, extending the whole machine service life. The closed circulating water cooling system ensures continuous and efficient heat dissipation, completely avoiding overheating shutdown faults in high-temperature summer environments. Meanwhile, the comprehensive intelligent safety protection system can automatically alarm and shut down in case of low oil pressure, high water temperature, overload, short circuit and overspeed, fully protecting the unit and eliminating potential operational safety hazards.
The whole machine adopts integrated compact base design with reasonable internal layout and small floor space, supporting fixed indoor installation and mobile trailer refitting. It can meet the dual needs of long-term fixed emergency standby power for large industrial plants and short-term mobile temporary power for municipal key projects. Complying with non-road T2 emission standards, the unit has low exhaust pollution and meets environmental assessment requirements of various industrial parks and urban construction zones. Backed by Yuchai’s mature industrial power technology and nationwide after-sales service network, this 125kVA diesel generator has low failure rate, stable operation and high cost performance, which is a cost-effective choice for medium and high-power power supply scenarios.
