On November 18, workers produced assembled car engines on modern production lines.
Mercedes-Benz all domestic models will soon carry "Chinese heart." On November 18, the new engine plant of Beijing Benz was officially put into operation, with an initial production capacity of 300,000 units, which will increase to 500,000 units in 2015. The start-up of the new engine plant means that Beijing Benz has achieved improvement from simple vehicle production to mastering the manufacturing technology of core components. The plant is also Mercedes-Benz's only overseas engine plant.
The engine factory which rises on a wasteland near the South Sixth Ring Road has a total area of ​​300,000 square meters. The product covers 1.6 liters, 2.0 liters, 3.0 liters, 3.5 liters and other displacements. It will match the Beijing Mercedes-Benz C-Class sedan and the long wheelbase E-class. Cars, GLK-class off-road vehicles and Fujian Mercedes-Benz commercial vehicles and other Mercedes-Benz domestic models.
At present, the Beijing Mercedes-Benz engine assembly line can simultaneously assemble different types of engines. The M276 assembly line can produce twin-turbo engines and hybrid engines simultaneously, while the M274 assembly line can produce both M270 and M274 engines. "The engine is automatically put on and off the line, all important processes are fully automated assembly, to minimize the labor intensity of workers." Field technicians, each assembly trolley and tray are equipped with identification chip, automated robot arm can be "smart" to induction The accurate model and technical parameters of the engine arrived at the station to perform differentiated precision operations.
At the end of the assembly line, in addition to having a helium leak test station to check for fine leaks that are invisible to the naked eye on the high-pressure rail, all engines that are assembled will also undergo cold and hot tests, respectively.
"The former is the engine is not ignited, the motor traction under the test, the latter is the ignition test engine operating quality and emissions." Beijing Benz relevant responsible person revealed that in the initial phase of capacity ramp-up production, engine thermal testing will be implemented 100%, Instead of the regular proportional sampling. In addition, the use of advanced technologies such as twin turbochargers, in-cylinder direct-injection stratified combustion, variable intake lift, tunable oil pumps, intelligent start-stop, etc., enables domestic Mercedes-Benz engines to achieve high power and low fuel consumption. Low emission uniformity.
The Beijing Benz engine plant, which is fully operational, is a veritable green factory. Although the machining process of the cylinder head, cylinder block, and crankshaft is inseparable from the lubrication and cooling of the emulsion, a little odor is not heard in the workshop. Originally, when the factory was laid the foundation, the first construction was the closed emulsion liquid supply system. The viscous emulsion containing metal chips could be used for recycling, and the discharge of waste liquid was reduced by 50%. Even the exhaust gas generated by the engine heat test is all recycled through a dedicated pipeline.
"This not only shows that Daimler's emphasis on the Chinese market has changed substantially, but also marks the transfer of Daimler's core technology to China." Senior Executive Vice President of Beijing Mercedes-Benz Cai Suiping revealed that in meeting the needs of domestic models Next, the core components of the Beijing Benz engine plant will also be exported overseas. In the next step, with the completion of the R&D center, the development of Beijing Benz’s own brands and new energy vehicles will accelerate.
The function of the Hydraulic Filter is to filter out various impurities in the hydraulic system. The main sources are mechanical impurities that remain in the hydraulic system after cleaning, such as rust, cast sand, welding slag, iron filings, paint and cotton yarn, etc., external impurities entering the hydraulic system, such as through the oil filler entrance and dust entering at the scraper seal; impurities generated during the working process, such as debris formed by the hydraulic action of the seal, metal powder generated by relative wear and movement, colloid, asphaltene, carbon residue, etc. due to oxidative deterioration of the oil.
