Request a Quote
Description
Developed in collaboration with renowned domestic and international combustion engine research institutes, including AVL from Austria and RICARDO from UK, Z series diesel engines are a result of our rich experience in diesel engine development, production, and quality management. They feature strong power and excellent performance, characterized by superior NVH (Noise, Vibration, and Harshness) performance, low thermal load, and good fuel efficiency. Since their launch, more than 300,000 units have been produced, making them the ideal choice for generator sets ranging from 10-81kW in various application fields.
