Today, Volkswagen Group (China) announced its full-year sales in 2017: In 2017, Volkswagen Group (China) and two joint ventures, SAIC Volkswagen and FAW-Volkswagen, delivered a record to customers in mainland China and Hong Kong. 4.18 million units (delivered 3.98 million units in the same period in 2016, an increase of 5.1% year-on-year), of which 189,000 imported models were delivered. With this result, the sales volume of Volkswagen Group (China) in 2017 exceeded the overall growth rate of the passenger vehicle market by about 4%. Prof. Dr. Jochem Heizmann, member of the management board of Volkswagen Group and president and CEO of Volkswagen Group (China), said: "In the Chinese market, we have gained the valuable trust of more than 4 million customers like never before. An important milestone is the Volkswagen Group's commitment to creating an exciting consumer experience for its customers and meeting their customers' needs."
“It is worth noting that a large part of the vehicles delivered by Volkswagen Group (China) in 2017 came from the traditional vehicle segment we covered. With the launch of the SUV offensive, and based on the strong market performance at the end of last year, We are full of confidence in the Group's market prospects in 2018.†Professor Heizman said, “We look forward to further promoting the Group's transformation under the guidance of 'Joining Together – 2025 Strategy'. We will continue to work on R&D and launch. Customer-oriented new technology, implementing electric vehicle strategy, continuous innovation and exploration, and actively exploring opportunities in the new mobile travel field. Through this series of measures, we aim to achieve the overall goal of the Group's development and provide the most suitable mobile travel for the Chinese market. Solutions to meet customer needs."
With its strong market performance, the Volkswagen brand continues to be the first choice for consumers in the Chinese passenger car market. In 2017, a total of approximately 3.18 million vehicles were delivered (2.99 million units delivered in the same period in 2016, a year-on-year increase of 5.9%), a record high. . December also became the best month in the history of the brand, with more than 342,100 cars being delivered to consumers. In addition, SUV sales continued to grow, with a delivery of 337,000 units, the Tiguan and Tiguan family models achieved an annual growth of 41.8%.
In 2017, the Audi brand's annual car delivery increased by 1.1% to 597,900 units. With this record-breaking sales record, the Audi brand continues to maintain its leading position in the luxury car segment of China. After November, the Chinese market once again became the single market with the highest growth rate of the Audi brand last month. The monthly sales volume increased by 34.3% year-on-year, reaching an unprecedented 69,200 units.
Skoda Auto gained the best market performance in the Chinese market last year, delivering a total of 325,000 vehicles to customers throughout the year (317,100 units delivered in the same period in 2016, up 2.5% year-on-year), of which 42,400 were delivered in December, the most in history. Good sales, up 41.8% compared to the same period in 2016. The Czech brand Skoda has set another new record in its largest single market.
In terms of high-end brands, Porsche delivered a total of 71,500 vehicles in 2017 (65,200 units delivered in the same period in 2016), a year-on-year increase of 9.6%.
A Solenoid Valve is an electromechanically operated valve. The valve is controlled by an electric current through a solenoid: in the case of a two-port valve the flow is switched on or off; in the case of a three-port valve, the outflow is switched between the two outlet ports. Multiple solenoid valves can be placed together on a manifold.
Solenoid valves are the most frequently used control elements in fluidics. Their tasks are to shut off, release, dose, distribute or mix fluids. They are found in many application areas. Solenoids offer fast and safe switching, high reliability, long service life, good medium compatibility of the materials used, low control power and compact design.
Besides the plunger-type actuator which is used most frequently, pivoted-armature actuators and rocker actuators are also used.
Solenoid valve designs have many variations and challenges.
Common components of a solenoid valve:
-
Solenoid subassembly
-
Retaining clip (a.k.a. coil clip)
-
Solenoid Valve Timer
-
Solenoid Coil (with magnetic return path)
-
Core tube (a.k.a. armature tube, plunger tube, solenoid valve tube, sleeve, guide assembly)
-
Plugnut (a.k.a. fixed core)
-
Shading coil (a.k.a. shading ring)
-
Core spring (a.k.a. counter spring)
-
Core (a.k.a. plunger, armature)
-
Core tube–bonnet seal
-
Bonnet (a.k.a. cover)
-
Bonnet–diaphram–body seal
-
Hanger spring
-
Backup washer
-
Diaphram
-
Disk
-
Valve body
-
Seat
-
air valve
-
water inlet valve
-
control valve
The core or plunger is the magnetic component that moves when the solenoid is energized. The core is coaxial with the solenoid. The core's movement will make or break the seals that control the movement of the fluid. When the coil is not energized, springs will hold the core in its normal position.
The plugnut is also coaxial.
The core tube contains and guides the core. It also retains the plugnut and may seal the fluid. To optimize the movement of the core, the core tube needs to be nonmagnetic. If the core tube were magnetic, then it would offer a shunt path for the field lines. In some designs, the core tube is an enclosed metal shell produced by deep drawing. Such a design simplifies the sealing problems because the fluid cannot escape from the enclosure, but the design also increases the magnetic path resistance because the magnetic path must traverse the thickness of the core tube twice: once near the plugnut and once near the core. In some other designs, the core tube is not closed but rather an open tube that slips over one end of the plugnut. To retain the plugnut, the tube might be crimped to the plugnut. An O-ring seal between the tube and the plugnut will prevent the fluid from escaping.
The solenoid coil consists of many turns of copper wire that surround the core tube and induce the movement of the core. The coil is often encapsulated in epoxy. The coil also has an iron frame that provides a low magnetic path resistance.
