Introduction
YC6A series engine through long-term market trial, is a mature product with excellent performance and high reliability; the market quantity of it is more than one million. Such model YC6A245L-D21 is developed for the characteristics of generator unit, which is characterized by high cost performance, easy use and maintenance。
Product Features
1.The engine body is made of high strength alloy cast iron, making the entire engine highly reliable even after many years of service.
2.Stable operation: Electronic speed governing is adopted, ensuring small rotation speed fluctuation, stable operation, low steady speed droop and quick transient response.
3.Easy maintenance: The universal rate of the parts and the parts for the products in the 6A production batch is over 90%.
4.G3 performance requirements for generator set are met.

Notes:
1. Prime Power: which corresponds to the basic power (PRP) described in ISO 8528. Implement the maintenance according to the Yuchai's
requirement, maximum power of variable load continuous output unlimited time. The average output power shall not exceed 70% of the
prime power in every 24 hours of operation.
Standby Power: In correspondence with the emergency standby power (ESP) stated in ISO 8528. Implement the maintenance according to
the Yuchai's requirement, maximum power at a variable load in the event of a main power network failure up to a maximum of 200 hours
per year. The average output power shall not exceed 70% of the standby power in every 24 hours of operation.
2. The engine power data stated in the table is the measured performance under the condition stated in ISO 8528-1 and ISO 3046.
3. The power output of the generator unit is calculated according to the efficiency of the AC generator. Thus, it is for reference only.
4. The kVA and kW values are converted as per standard power factor 0.8.
