Recently, Weichai officially released a new H-platform and a new H-platform WP9H/WP10H engine. With an engine life of 1.8 million km/30,000 hours, this engine sets the highest standards for high-speed, heavy-duty engine life. At the beginning of the design of the WP9H/WP10H product, the R&D team put reliability first, combined with the experience of Weichai's 35 years of heavy engine R&D, and determined the target value of overall machine development reliability and life, based on actual use. Accumulation of situation and reliability study data, target-level decomposition of each system and component, and reliability design prediction of each system and component through high-precision virtual prototype simulation technology to ensure the design of components and systems can be achieved The goal of overall reliability. In the development phase, relying on the state-level key laboratory of internal combustion engine reliability, which represents the highest level of reliability in China's internal combustion engine research and development, adopting the industry's most rigorous R&D process, the durability assessment index far exceeds that of the same industry: the product rig verification test cumulatively exceeds 45,000 hours, 300 units. The total road durability test exceeds 50 million kilometers. H platform "Longevity Black Technology" Advanced structural design 1. Gantry cylinder body, synchronized with the latest European concept The Weichai WP9H/WP10H diesel engine block design is synchronized with the latest concept in Europe. It adopts a gantry type cylinder block, a drum-shaped skirt, high strength, and can withstand up to 24MPa explosion pressure; adopts wet top positioning cylinder sleeve, high cooling, lower cylinder liner upper Temperature, improve the reliability of the whole machine. 2. Four-valve monoblock cylinder head TOP-DOWN cooling The four-valve monoblock cylinder head adopts the latest cooling concept, namely TOP-DOWN cooling. The cooling water flows through the cylinder head water jacket from top to bottom. Firstly, the heat load in the cylinder head is cooled to a higher position, which can effectively reduce the heat load. Exhaust valve nose bridge area, fuel injectors, valve seats and other components have been better protected by cooling. 3. Side-mounted camshaft, compression release brake With the side camshaft, the crankshaft gear and the camshaft gear have a short center distance, the transmission chain is short, and the wear is small. This avoids reliability problems such as high noise of the overhead camshaft and easy leakage between the cylinder block and the cylinder head. At the same time, the use of compression-released brakes achieves a high braking power design with a braking power of up to 26 kW/L, a 50% increase in efficiency over exhaust brakes, and no need for exhaust brake butterfly valves, resulting in a more reliable system. 4. Infinite life fatigue test verification of connecting rod Forged steel crankshaft, breaking connecting rod, high strength, passed the infinite life fatigue test verification. 5. Modular integrated design, oil change cycle of 100,000 kilometers The oil module integrates the cooler, filter, rotor filter, water filter and pressure limiting valve. The modular integrated design greatly reduces the frequency of engine failure and achieves excellent reliability. The oil rotor filter can effectively remove tiny impurities and soot in the oil, providing higher reliability for the reliability of the whole machine. Weichai WP9H/WP10H has a 100,000-kilometer long oil change cycle. The oil filter only changes the filter element without shell replacement, which greatly reduces maintenance costs. Full test verification: Bench test exceeds 45,000 hours, road test exceeds 50 million kilometers The Weichai WP9H/WP10H engine has been verified by a cumulative bench test in a national key laboratory exceeding 45,000 hours; 300 vehicle road tests have accumulated over 50 million kilometers in total. The WP9H/WP10H diesel engine has a long life of 30,000 hours and can achieve a long life of 1,250 days and a distance of 1.8 million kilometers, equivalent to 45 revolutions around the earth. The engine and the vehicle have been verified through severe environmental tests. There is no auxiliary measure - normal start at -20°C, with auxiliary air inlet heating system, normal start at -35°C; power is not lost in normal operating conditions at an altitude of 4700 metres, 1.5% slope is not reduced block. Weichai WISE Autonomous ECU: For reliability and escort, Weichai's autonomous ECU power self-adapting control strategy judges the current output of the diesel engine in real time and compares it with the design value to prevent engine over-power operation and ensure reliability. Weichai wisdom cloud platform: Big data supports high quality, smart cloud platform real-time monitoring of engine operating conditions, to achieve fault pre-judgment, remote diagnosis and other functions to allow users to rest assured; based on big data mining analysis, continuous improvement of engine product quality. H Platform "Powerful Black Technology" WP9H/WP10H engine power coverage 290PS-400PS, special purpose power up to 700PS, maximum torque of 1900Nm, up torque of 200Nm/L, special purpose torque of 2300Nm; low speed high torque, maximum torque speed extends to 1000r/min, can match the small speed Than the rear axle, reduce engine speed, energy efficient. The WP9H/WP10H's power, torque, power, and torque are significantly higher than those of the same displacement product. At the same time, the Weichai WSIE autonomous ECU is equipped with an emergency acceleration strategy (EACC) that can intelligently recognize the driver's need for rapid acceleration, the engine quickly increases the torque, the climb does not decrease, and the power is upgraded. H platform "economizing black technology" The WP9H/WP10H engine is equipped with a mature electronically-controlled high pressure common rail technology. It uses mature 4-valve technology, optimizes the combustion design, and has an industry-leading fuel injection system of 2000bar. The design of the new combustion chamber and the air duct matches the design of the oil and gas mixture. More fully, the combustion efficiency is higher and the minimum fuel consumption rate is 185g/kWh. The WISE autonomous ECU provides an intelligent optimization strategy for the work area to achieve adaptive variable-speed cruise control, self-adaptive road conditions, intelligent flushing, and real-time intelligent multi-power estimation of the load, making the vehicle more fuel efficient. H Platform "Low NVH Black Technology" The WP9H/WP10H engine adopts the latest design concept to positively control the NVH index, reduce noise and improve quality. Design of rear gear chamber and under camshaft; piston cooling control technology, multiple injection strategies to optimize combustion noise, noise control for transmission and accessories. Weichai WP9H/WP10H diesel engine noise is 1dBA~3dBA lower than that of the same displacement product. H Platform "Low Emission Black Technology" The WP9H/WP10H engine adopts an efficient SCR control technology independently developed by Weichai. The DOC-DPF-SCR post-processing system is equipped with a unique DPF regeneration strategy to meet Euro VI emissions, the same for the National V and Euro VI base machines, and the vehicle has a good adaptability to match. .
