2. Product Features

The Yuchai YCDV254FHZ-40 24kW/30kVA diesel generator set is a newly upgraded small and medium-power power generation device based on Yuchai V25 mature engine platform. As a hot-selling 30kVA diesel generator for civilian and industrial dual-use, this unit balances stable power output, low fuel consumption and low failure rate, and solves many pain points of traditional small generator sets such as unstable voltage, high fuel consumption and difficult maintenance in actual use.

In terms of power stability, the unit supports 50Hz fixed-frequency stable operation, with 24kW continuous prime power and 26.4kW standby power reserve. It can bear long-term full-load operation and instantaneous equipment startup surge load without voltage drop or frequency drift. Matched with brushless self-excited alternator and high-precision AVR automatic voltage regulation system, the three-phase output voltage is balanced, which can effectively protect precision electrical instruments, monitoring equipment and office electrical appliances from damage caused by current fluctuation. The H-class insulation material greatly improves the high-temperature resistance of the alternator, avoiding insulation aging and short-circuit faults caused by long-term high-load operation.

Energy-saving and high efficiency is the core advantage of this Yuchai diesel generator set. Adopting electronic high-pressure common rail fuel injection technology and optimized direct injection combustion chamber structure, the full-load fuel consumption is stably controlled at 8.1L/H. Compared with peer 30kVA diesel generator products, it has lower comprehensive operating cost, which is very suitable for frequent startup and long-term standby power scenarios. The 4-cylinder in-line water-cooled engine structure runs smoothly with small vibration, effectively reducing mechanical loss and extending the overall service life of the unit.

The unit has excellent environmental adaptability and safety performance. The IP23 protection grade can effectively resist external dust and splashing rainwater, adapting to outdoor open-air placement and harsh indoor working conditions. Equipped with a complete intelligent protection system, it can automatically alarm and shut down in case of low oil pressure, high water temperature, overload and short circuit, which fundamentally avoids equipment burnout and operation safety accidents. Different from brushed generators, the brushless self-excited design has no vulnerable carbon brush parts, realizing maintenance-free operation for a long time, greatly reducing later maintenance time and cost for users.

In terms of installation and use, the whole machine adopts an integrated compact structure with reasonable layout and small floor space. The reserved forklift holes and flexible mounting structure support fixed installation and mobile trailer transformation, meeting the dual needs of fixed standby power and mobile temporary power supply. With reliable Yuchai original engine power, simple operation and strong universality, this 24kW standby diesel generator has high cost performance and is one of the most practical small industrial power generation equipment in the current market.
