YUCHAI YC4V55Z-D20 Diesel Generator for Prime & Standby

YC4V55Z-D20 Generator | 20kW Yuchai Diesel Genset

If reliable backup power is what you need, the YC4V55Z-D20 diesel genset delivers exactly that. Built around a Yuchai 4-cylinder water-cooled engine, this 20kW generator set offers prime and standby power with clean voltage output for small industrial, agricultural, or commercial use.

Core Specs at a Glance:

• Engine Model: YC4V55Z-D20

• Configuration: In-line 4-cylinder, water-cooled, 4-stroke diesel

• Displacement: 2.156L | Bore x Stroke: 85mm x 95mm

• Prime Power: 20kW (25kVA) | Standby: 22kW (27.5kVA)

• Voltage: 230/400V, 3-phase 4-wire | Frequency: 50Hz

• Speed: 1500 RPM | Alternator: Brushless, self-excited, H-Class insulation

• Fuel Consumption @100% Load: ≤5.8 L/h

• Net Weight (open set): approx. 650 kg

Why This Genset Stands Out:
The 2.156L displacement and 1500 RPM synchronous speed give this diesel generator excellent fuel efficiency and low wear. Closed-loop water cooling ensures stable temperatures even during extended runs, while the brushless alternator delivers steady voltage safe for sensitive electronics. With H-Class insulation rated for high-heat environments, this generator set is built to endure. From shop backup to construction-site prime power, the YC4V55Z-D20 keeps your operations humming—reliably, quietly, and affordably.
