产品概述
Developed based on the WP4.6N diesel engine, with a maximum power of 200 Ps, it meets the power requirements of natural gas city buses.
产品优势
High reliability: High-strength materials and refined fit clearances improve the safety factor and ensure product reliability.
High fuel economy: Optimized selection, improved efficiency, and reduced resistance further enhance economy; high-precision air-fuel ratio and micro-knock control technologies reduce engine gas consumption by 5–7 g/kW·h.
High comfort: Added secondary balancer, reducing vibration velocity intensity from 43.1 mm/s to 27.0 mm/s, with autonomous control to prevent common issues such as misfires and knocking.
