The XK Yuchai series diesel generator sets are built with genuine Yuchai diesel engines (manufactured by Guangxi Yuchai Machinery Co., Ltd., one of China's leading diesel engine manufacturers), matched with premium brushless synchronous alternators and intelligent control systems. Renowned for high reliability, low fuel consumption and easy maintenance, this series is widely used for emergency standby and prime power supply in commercial buildings, construction sites, manufacturing facilities and telecommunication stations.
Key Product Highlights
Genuine Yuchai Engine: Adopts original Yuchai inline diesel engines with mature technology and 60+ years of manufacturing heritage, delivering stable performance and long service life.
Wide Power Range: Covers 30kW-1000kW (37.5kVA-1250kVA) standby power, available in 50Hz (1500rpm) and 60Hz (1800rpm) to meet global market requirements.
Excellent Fuel Economy: Optimized high-pressure direct injection combustion system achieves fuel consumption as low as 200g/kW*h at full load, greatly reducing long-term operating costs.
Strong Environmental Adaptability: Works reliably in high temperature, high altitude and dusty environments, with good cold start performance for harsh climate regions.
Flexible Customization: Open frame, silent canopy, containerized and trailer-mounted types available; alternator, controller and auxiliary systems can be configured on demand.
Product Overview
The XK Yuchai series genset integrates a Yuchai diesel engine, a brushless synchronous alternator, an automatic control panel and a heavy-duty common base frame on a single integrated skid. Every unit undergoes strict no-load test, full-load test and step-load test before delivery to ensure stable voltage and frequency output under all working conditions.
This product line is optimized for both standby and prime power scenarios. With a closed-cycle cooling system, efficient lubrication system and dual-stage air filtration, it supports long-hour continuous operation, making it an ideal cost-effective power solution for global engineering projects and commercial facilities.
Core Technical Advantages
High-Reliability Engine Structure: High-strength alloy cast iron cylinder block and forged crankshaft provide excellent rigidity and impact resistance, with an overhaul interval of up to 15,000+ running hours under proper maintenance.
Efficient & Clean Combustion: High-pressure fuel injection pump matched with precision injectors ensures full fuel atomization and complete combustion, achieving both low fuel consumption and compliant exhaust emissions.
Reliable Cold Start Performance: Equipped with an electric preheating system and high-torque starter motor, the unit can start smoothly at ambient temperatures as low as -15℃ without extra auxiliary heating.
Easy Maintenance & Global Parts Support: Modular layout, centralized service points and universally interchangeable wearing parts simplify on-site maintenance. Yuchai's mature global spare parts network ensures low-cost, fast after-sales support worldwide.
