A few days ago, the reporter learned from Quanchai Power Co., Ltd. that the company's “4B Energy-saving and Environment-friendly Diesel Engine Key Technology Research†was supported by the Provincial Science and Technology Agency's international cooperation project and will soon cooperate with foreign well-known diesel engine design companies to develop vehicles that meet the requirements of China V emission standards. Use diesel engine.
According to reports, the company has adopted the international 4S R&D platform and adopted electronically-controlled high pressure common rail, supercharged intercooling, exhaust gas recirculation, on-board diagnostic system (OBD) and post-processing (SCR) technology through international scientific and technological cooperation. The route has optimized the design of the air intake system, air distribution mechanism and cooling system, and reasonably matches the combustion chamber with the fuel injection system, thereby developing an energy-saving and environmentally-friendly vehicle diesel engine that satisfies the requirements of the National V emission standard.
Anhui Quanchai Group Co., Ltd. (hereinafter referred to as “Quanchaiâ€) was founded in 1949. It is a large-scale group enterprise integrating R&D, production, operation, foreign trade and investment. At present, the company has more than 3,000 employees. The company has wholly owned or controlled subsidiaries such as Quanchai Power, Tianli Power, Tianhe Machinery, Oubo Pipe, Jintian Machinery, and Fulian Real Estate. With an annual output of 500,000 series of multi-cylinder diesel engine, 50,000 tons of plastic pipe and 200,000 sets of automotive interior parts production and marketing capabilities.
A ballcock (also balltap or float valve) is a mechanism or machine for filling water tanks, such as those found in flush toilets, while avoiding overflow and (in the event of low water pressure) backflow. The modern ballcock was invented by José Antonio de Alzate y RamÃrez, a Mexican priest and scientist, who described the device in 1790 in the Gaceta de Literatura Méxicana.[1] It consists of a valve connected to a hollow sealed float by means of a lever, mounted near the top of the tank. The float is often ball-shaped, hence the name ballcock. The valve is connected to the incoming water supply, and is opened and closed by the lever which has the float mounted on the end. When the water level rises, the float rises with it; once it rises to a pre-set level, the mechanism forces the lever to close the valve and shut off the water flow. This is an example of negative feedback and of proportional control.
