1000KW Yuchai Diesel Generator Engine YC6C1660-D30 Technical Data

Jul. 27, 2019

Yuchai YC6C series engine is a self-developed product by Yuchai combining the advanced technology for large engines both at home and abroad. The configurations, such as four valves, turbocharged intercooled, electronic unit pump, are adopted for it; and it is optimized and verified through the advanced combustion development technology of Yuchai, and is characterized by energy-saving and environment-friendly, high reliability, strong loading capability and good maintainability.

Yuchai Generator YC6C1660-D30 Engine Characteristics

1. The technologies for four valves and turbocharged intercooled are adopted for ensuring sufficient air intake, full combustion and low fuel consumption.

2. Electronic unit pump technology is adopted for ensuring stable operation, good transient speed governing performance, and strong loading capability.

3. High-quality alloy cast iron cylinder block of reinforced grid structure with cambered surface, high-strength vermicular iron cylinder head, dual protection anti-impact cylinder gasket structure, and self-developed cooling technology for the bottom of the cylinder head are adopted, which ensure high reliability.

4. The Yuchai proprietary carbon-scraping self-cleaning technology is adopted for ensuring low lubricating oil consumption.

5. Electric pre-supply oil technology is adopted, which effectively protects kinematic pair and improves the service life of engine.

6. The structure of one head for one cylinder is adopted; maintenance window is set at the side of the engine body, which ensures easy maintenance.

7. Support dual energy start.
