Products
（1）600kW~1000kW prime genset, for continuous and stable power supply.
（2）660kW~1100kW standby genset, for reliable and fast standby power supply.
One head for one cylinder, with a maintenance window on the side of the engine body, which is convenient for maintenance. Support dual-energy startup.
Electric pre-fueling technology is adopted to effectively protect the kinematic pair and prolong the service life of the engine.
The high-quality alloy cast iron cylinder block with an arc-reinforcing rib grid structure, high-strength vermicular cast iron cylinder head, double-safety anti-impact cylinder gasket structure, and original cooling technology at the bottom of the cylinder head are applied, with high reliability.
The electronically-control fuel injection system is adopted, with stable operation, good transient speed regulation, and strong loading capacity.
Four-valve and turbocharged & intercooled technologies, ensuring sufficient air intake, sufficient combustion, and low fuel consumption. Yuchai's patented carbon scraping and self-cleaning technology ensures low lubricating oil consumption.
