Yuchai United Power Co., Ltd. is a joint venture between Jirui United Heavy Industry, Guangxi Yuchai and Shenzhen Jiusi Investment. It was established in August 2009 in Wuhu, Anhui. Jirui Union Heavy Industry and Guangxi Yuchai respectively accounted for 45% of the shares, and Jiusi Investment accounted for 10% of the shares. The company is located in Linjiang Development Zone, Wuhu City, Anhui Province. In November 2009, Yuchai United Power's main production base was under construction. The registered capital of the company is 500 million yuan. The project is planned in one time and is constructed in three phases. In the first phase, the company will invest 800 million yuan and plan to produce 60,000 engines per year, including the engine block, cylinder head and trial production line. The construction area will be 70,000 tons. It will be completed by the end of 2010. With a total investment of over 1.5 billion yuan, it is expected to eventually produce a production capacity of 200,000 heavy-duty vehicle engines annually.

YC6K product series and features
On December 18, 2010, the joint truck teamed up with United Power to hold a grand brand release and product launch ceremony. As a joint force of the joint truck core strategic alliance, it also announced its own power brand, which also indicated that the YC6K12 engine was officially launched.
The YC6K product series has three types of emissions: 10.5L, 12L and 13L. The emissions can meet the requirements of the country 3 to country 5 and even Euro 6; the power can cover 300 to 560 horsepower, and the diesel (or LNG/CNG/methanol) can be used. Single fuel and dual fuel engines. The average fault interval mileage is 100,000 km; for the B10 life, the K10 series can reach 1 million Km or more, and the K12 series can reach 1.6 million km or more.
YC6K series engines of Yuchai United Power Co., Ltd. are independently developed based on the Mercedes-Benz DD13/15 engine, integrating the latest technological achievements in the world and possessing more than 30 technological invention patents. The first use of reliability growth technology in the engine industry has broken through the reliability weaknesses of Chinese manufacturing; the introduction of precision combustion and electronic control technology, reverse cross-flow cooling technology of the engine, high-strength materials, and innovative use of high-efficiency engine cylinder braking technology have greatly improved. The engine life, with the latest technology in Europe in 2012 the level of production of the engine.
Low fuel consumption
All the technical performance indicators actually achieved by 6K are leading the same domestic engines, and the key fuel consumption and specific weight indicators are among the world's advanced levels. For example, the minimum fuel consumption and rated point fuel consumption are 5% to 8% lower than the world advanced level; the main structural parts are made of high-strength vermicular cast iron, and the weight of the engine is reduced by 15% compared with the conventional engine.
2. High efficiency reverse cooling technology
The cooling liquid flows from the cylinder head into the cylinder to cool, but the liquid flow rate is high, and the cooling efficiency is higher, so that the temperature of the injector installation area is reduced by about 15oC compared to the conventional diesel engine, so that the engine can withstand the explosion pressure of up to 220 bar, and the engine reliability can be realized.
3. Overhead camshaft technology (SOHC)
China's first top-mounted camshaft four-valve medium-duty diesel engine that meets Euro 3/Euro 4/Euro 5/Euro 6. The air distribution mechanism has high rigidity and noise is lower than that of conventional diesel engines.
4. Integrated integral cylinder head
The cylinder head is integrated with the intake pipe, the engine structure is more compact, and the failure of the intake pipe and its related parts can be fundamentally improved.
5. High pressure explosion technology
Wet cylinder head, upper end support, uniform cylinder head bolt arrangement, auxiliary advanced high-speed water cooling technology, small cylinder hole deformation, engine brake oil consumption rate BSFC index, engine oil consumption, B10 life and reliability, etc. Significantly improved; overhaul after high performance recovery. The gantry type cylinder block, the main bearing cover with side pressure fit, and the bottom reinforcing plate, the engine rigidity is significantly improved, and the deformation is smaller, so that the main bearing block of the cylinder block can withstand explosive forces of up to 220 bar, while obtaining the best NVH characteristics. The residual stress of the casting of vermicular cast iron (Rut400) cylinder block cover castings ensures that the residual stress is less than 50 MPa.
Rear cast aluminum gear chamber
Rear gear chamber, crankshaft vibration, low noise, powerful. At the same time meet the installation of common rail and single pump systems. Lightweight, high-strength cast aluminum flywheel housings are used to make the engine lighter and consume less fuel.
7. Completely centered PTO shaft
High-efficiency POT output as an optional configuration, output torque up to 100Nm, to meet the needs of cement trucks and other construction vehicles.
8. In-cylinder brake technology
The use of high-efficiency exhaust brakes produced by the United States JACOBS company, braking power up to 25kW / L, higher brake reliability.
9. Oil cooling system integration, low maintenance costs
The oil cooler integrates the machine filter, water pump and thermostat, and has a compact and powerful structure. The smart water inlet and outlet arrangement makes the oil cooler more efficient in cooling and lower in resistance to water flow. The corresponding maintenance costs are low.
10. Front-end wheel train enhancement technology
The front-end wheel train layout is optimized by Gates, a professional wheel train supplier in Germany, to ensure that the engine train wheels work more reliably. B10 has a lifetime of up to 1 million km.
Advanced and reliable production line and factory inspection
Yuchai United Power's production line is based on green manufacturing and zero defect, and combines cutting-edge technology with sustainable development. All major key equipments adopt international famous brands, which have high manufacturing precision and low energy consumption. Comprehensive application of on-line inspection technology, error prevention technology, safety and environmental protection technologies, and information technology, highly integrated advanced manufacturing and inspection equipment with intelligent quality control systems, ensuring that each process has the same characteristics and accuracy of each product and ensures high engine speed. quality. Including: the world's top-level foundry centers provide rough, imported processing equipment, 9 robot assembly lines, cold test + thermal test benches, 100% of important processes online closed-loop detection system, intelligent on-site manufacturing quality implementation System and so on.
Yuchai United Power has a complete and unique test equipment, with deep cold and heat shock test bench (-25°C～120°C), tilt test bench (45o front and back, left and right), dual power output test bench, plateau mobile rack, high temperature warehouse Test bench, vehicle thermal balance test bench, etc. The factory engine meets 40,000-hour rig evaluation, 1.5 million km of road test and so on.
The combined power delivery test determines the quality of qualified or not technical quality data is 58 parameters, and only 6 parameters at home and abroad, the load condition of the joint power delivery test is completely the same as the state of the vehicle, such as steering system, cooling system, Braking system, transient acceleration response, mechanical efficiency, consistent spectrum analysis.
United Power began with the concept design in 2007 and realized the simultaneous development of parts and components of internationally renowned brands. Such as starters, motors, high-pressure injection systems and German Bosch cooperation; piston components and the German Mahler, the United States Federal-Mogul cooperation; cylinder brakes and the United States can Bo cooperation; cylinder pad and Japan Ishikawa, high pressure pipeline and Japan Sakai, The pump was developed in cooperation with Constek UK, air pump and WABCO, steering pump and ZF, belts and gates.
According to reports, in 2011 Yuchai United Power Co., Ltd. expects to produce 12,000 engines. By 2015, it will strive to achieve an engine output of 120,000 units.
