- Our international 4 cylinder diesel engines have multiple advantages, including strong power, fuel economy, high reliability and eco-friendly emissions.
- Our diesel engines cover a wide power range. For example, some series of these engines have a power range of 441-784kW. They can meet the power needs of different users and different equipment, and are suitable for various application scenarios, from light vehicles to heavy construction machinery.
- Our four cylinder diesel engine pump set also have low maintenance costs and good part commonality. Yuchai diesel engines are highly serialized, so their parts are highly interchangeable. With a one-cylinder-one-head structure, they are easy to maintain, resulting in low overall maintenance costs and helping users save on maintenance expenses.
Question1:what is continuous power of diesel engine?
Answer 1:Continuous power(COP): Diesel engine can run anytime and continuous operation at constant load of maximum power. ISO standard power at constant load of maximum power. ISO standard power.
Question2:what is prime power of yuchai diesel engine ?
Prime Power(PRP): Diesel engine can run anytime and continuous operation under variable load maximum power. It can overload of 10% ISO standard power.
Question3:what is standby power?
Answer3:Standby Power(ESP): Diesel engine can running up to 200h by the maximum power of variable power per year. the ISO standard power be oil defined.
