Premium components ensuring durability, precision fit, and reliable performance across all models.
Dayun engine parts encompass a comprehensive range of components including cylinder blocks, cylinder heads, crankshafts, camshafts, piston rings, connecting rods, turbochargers, fuel injectors, oil pumps, water pumps, and gasket kits. Designed for Dayun’s heavy-duty trucks and commercial vehicles, these parts are precision-engineered to deliver reliable performance across diverse operating conditions. Every component is manufactured to strict quality standards, ensuring seamless compatibility with Dayun diesel and natural gas engines across N-series and V9 platforms.
Dayun trucks are predominantly powered by two world-class engine brands: Weichai Power and Cummins. Weichai serves as the primary engine supplier across Dayun’s extensive product lineup, while Cummins provides high-performance options for premium and heavy-duty applications. This strategic partnership ensures Dayun trucks deliver reliable power, excellent fuel efficiency, and superior performance across diverse operating conditions.
Weichai engines are the backbone of Dayun’s truck series. The WP10.5H series, available in 430hp and 460hp variants, powers the popular N8V models. The WP13 series delivers up to 550hp and 2550N·m of torque, equipped on flagship V9 and heavy-haul tractors. For natural gas applications, the WP13NG series offers 400-480hp options on N8V LNG trucks. Weichai engines also feature standard “Youshun” cylinder braking for enhanced safety.
Cummins engines equip Dayun’s premium models with advanced technology. The X12 series (440-470hp) powers N8V and N9 series tractors, while the X13 series delivers 510-560hp on V9 flagship models. The ISGe5 series (400-460hp) is featured on N8E and N8V variants. With low-end torque as early as 1000rpm, Cummins engines provide exceptional grade-climbing capability and fuel economy for long-haul operations.
