At a glance
The WP7H comes from an original Weichai diesel engine supplier and is built as an Inline unit, with 6.8 L displacement. Rated output spans 199–257 kW (270–350 Ps). Peak torque reaches 1300 N·m. It is supplied to meet Euro VI emission requirements. Typical duty is rear-engine bus service.
Product Overview
A completely new high-end platform with a strengthened engine structure, validated through comprehensive bench, “three-highs” (high temperature, extreme cold and high altitude) and complete-vehicle drum testing, so key components meet reliability requirements across operating conditions. The overhead camshaft, equal-journal-diameter crankshaft and high-precision gear design reduce idle noise to 77 dB(A) for a quieter, more comfortable ride.
Product Advantages
- Strong power. Maximum torque of 1,300 N·m across 1300-1700 r/min with low-speed torque above 1,100 N·m, giving brisk starts and excellent acceleration.
- Efficient and economical. High-efficiency turbocharging, ultra-high-pressure fuel injection and high-efficiency combustion cut fuel consumption by 1-2 L per 100 km against same-displacement products.
- Robust and durable. A high-strength structure that withstands higher peak firing pressure, with B10 life of up to 1,000,000 km for efficient reliability.
