Key Optimizations
- Dual VVT Upgrade: Intake & exhaust variable valve timing improves low-end torque and high-end power; fuel consumption reduced by 5%–8%
- China VI Emission Upgrade: Optimized combustion + upgraded catalyst meets China VI-b, drastically lowering NOx and PM emissions
- Timing Chain Replacement: Replaced timing belt with chain for 150,000+ km service life, maintenance-free and higher reliability
- Combustion System Refinement: Redesigned combustion chamber, injectors, and intake ports; thermal efficiency increased to >36%
- NVH Optimization: Reinforced crankshaft, piston, and block; vibration and noise reduced by 3–5 dB
- Lightweight & Durability: Aluminum head + optimized structure cuts 8kg; key components strengthened for 300,000+ km overhaul interval
Technical Features
Wide Torque Band: Delivers 145 N·m from 4200–4400 rpm for strong start, climb, and heavy-load performance
Fuel Efficiency: Combined fuel consumption 7.2–7.6 L/100km; compatible with 92# gasoline
Low Maintenance: Chain timing, long-life spark plugs, and high-part commonality
Strong Adaptability: Performs reliably in urban-rural heavy-duty, frequent start-stop, high-temperature, and high-humidity conditions
