2021 Sitrak 6x4

This Euro‑5 electronic common‑rail diesel engine is widely fitted on heavy‑duty dump trucks for construction, quarry and mining operations. It adopts electronically controlled high‑pressure common‑rail fuel injection together with SCR urea exhaust after‑treatment system to meet Euro‑5 emission standards. Compared with traditional mechanical‑pump engines, it delivers improved fuel atomisation, better fuel economy and lower exhaust emissions. ## Key Specifications (Example: Weichai WP8.340E51) - Engine Model: WP8.340E51 - Configuration: Inline 6‑cylinder, turbocharged & inter‑cooled - Displacement: 7.8 L - Rated Power: 250 kW (340 HP) - Maximum Torque: 1400 N·m @ 1200‑1700 rpm - Fuel System: Electronically controlled high‑pressure common‑rail injection - Emission Standard: Euro‑5 (SCR urea after‑treatment required) ## Core Advantages ✅ **Strong low‑end torque**: Peak torque available at low‑mid rpm, ideal for heavy‑load start‑up, climbing and rough‑site haulage for muck, sand, gravel and ore. ✅ **Better fuel efficiency**: ECU precisely controls injection timing and fuel quantity for complete combustion, reducing overall fuel consumption. ✅ **Mature & widely supported unit**: Large global installation base, spare parts are easily accessible in most overseas markets. ✅ **Reliable power output**: Proven industrial powertrain built for continuous heavy‑duty cycles on construction and mine sites.
