2. Product Features

The Yuchai YC4D60-D25 32kW/40kVA diesel generator set is a mature medium-power power generation equipment built on Yuchai classic 4D series engine platform. As a hot-selling 40kVA diesel generator in the market, this unit is independently equipped with Yuchai original YC4D60-D25 diesel engine, featuring sufficient power reserve, stable operation and low failure rate. It effectively makes up for the shortcomings of unstable power output and poor durability of ordinary medium-power generator sets, and is widely recognized in civil, engineering and industrial standby power fields.

In terms of power stability, the unit supports 32kW long-term continuous prime power output and 35.2kW emergency standby power supply. The reasonable power margin allows the equipment to run stably under full-load conditions for a long time, and can cope with the instantaneous starting surge of mechanical equipment and electrical loads without voltage drop or frequency drift. Matched with high-quality brushless self-excited alternator and high-precision AVR automatic voltage regulation system, the 50Hz fixed-frequency three-phase voltage output is balanced and stable, with almost no current fluctuation. Equipped with H-grade high-temperature resistant insulation materials, it can effectively avoid insulation aging and short-circuit faults caused by long-term high-load operation, providing reliable protection for precision electrical equipment.

Low maintenance cost and strong environmental adaptability are the core advantages of this 32kW standby diesel generator set. Different from traditional brushed generators that require regular carbon brush replacement, the brushless self-excited design eliminates vulnerable wearing parts, realizing long-term maintenance-free operation and greatly reducing daily maintenance workload and later operating costs for users. The IP23 professional protection grade can effectively block external dust, debris and splashing rainwater, adapting to outdoor open-air placement and harsh construction site working environments. The closed circulating water cooling system ensures continuous and efficient heat dissipation, and the unit will not overheat and shut down even in high-temperature summer working conditions.

In terms of fuel economy and operational reliability, the YC4D60-D25 engine adopts optimized direct injection combustion technology and electronic fuel governor, with full-load fuel consumption stably controlled at 10.5L/H. The combustion is sufficient and the fuel consumption curve is flat, which can maintain good energy-saving performance in long-term variable-load operation. The four-cylinder in-line water-cooled structure runs smoothly with low vibration and low noise, bringing a more friendly on-site operation environment. Meanwhile, the unit is equipped with a complete intelligent protection system, which can automatically alarm and shut down in case of low oil pressure, high water temperature, overload and short circuit, fundamentally avoiding equipment burnout and operation safety accidents.

Compact structure and high cost performance make this Yuchai 40kVA diesel generator highly practical. The whole machine adopts an integrated base design with reasonable layout and small floor space, supporting fixed installation for long-term standby power supply and mobile trailer refitting for temporary power use. With Yuchai’s mature manufacturing technology and strict factory testing, the unit has stable quality, strong universality and complete after-sales service network, which is the preferred medium-power power generation equipment for small and medium-sized users.
