3. The top of the diesel Engine Piston often has a variety of pits, and its specific shape, position and size must be adapted to the formation and combustion requirements of the diesel engine mixture.
The production process of a piston usually involves several steps, including casting, machining, heat treatment, surface treatment and assembly. MITSUBISHI Piston set,Engine piston set for MITSUBISHI,Original piston Set,Original MITSUBISHI Engine piston 1D auto parts , https://www.1dauto.com
1. Casting: The first step in the piston production process is casting. This involves pouring molten metal, such as aluminum alloy or cast iron, into a mold to form the desired piston shape.
2. Machining: Once the piston is cast, it is machined to perfect its shape and size. This involves using cutting tools, such as lathes and milling machines, to remove excess material and create the final shape of the piston.
3. Heat treatment: After processing, the piston is usually heat treated to improve its mechanical properties. This involves subjecting the piston to high temperatures and then cooling it slowly to achieve the desired level of hardness and strength.
4. Surface treatment: The piston is then subjected to surface treatment, such as anodizing or coating, to prevent wear and corrosion. Anodizing involves forming a protective oxide layer on the surface of the piston, while coating involves coating a material, such as ceramic or polymer, on the surface of the piston.
5. Assembly: Finally, the piston is assembled into a complete engine assembly with other components, such as piston rings and connecting rods.
The installation process must properly assemble the piston and other components together to ensure the normal operation and performance of the engine.
July Dongbei billion optical power revenue list fell year-on-year
Dongbei Optoelectronics announced on July 7 that the consolidated revenue in July was 500 million yuan (NT$, the same below, equivalent to RMB 98.05 million), down 16.6% from the previous month and a significant decrease of 37.4% from the same period last year. Dong Bei Optoelectronics spokesperson Weng Congzhi said that the overall slowdown in July was mainly due to the international light fixtures clearing the light bulb inventory at a low price, affecting the market price order. In this regard, in addition to maintaining the current high-end performance models, Dongbei will also launch a low-cost design version of the bulb products to actively respond to market demand, it is estimated that after the third quarter, order demand should be seen monthly. Weng Congzhi pointed out that Philips, a large European and American manufacturer, vigorously promoted low-temperature bulbs of semi-circular LEDs. At present, the retail price of LED bulbs is about 3~4 yuan per piece, which has completely replaced the traditional energy-saving bulbs (CFL). Supply and demand and consumption will help. The global LED bulb penetration rate is only about 10-13% as of the first half of this year. Under the new lighting bulb architecture, it is estimated that the LED lighting penetration rate will double in the second half of the year, equivalent to one year of new creation. The demand for 10 to 1.2 billion bulbs. In addition, LED manufacturers Yiguang, Jingdian also announced the July revenue. Yiguang announced on the 7th that its revenue in July 2015 was 2.253 billion yuan (equivalent to RMB 442 million), down 7.21% from the previous month and down 13.75% from the same period last year. The accumulated revenue from January to July 2015 was 165.53. 100 million yuan (equivalent to about RMB 3.249 billion), an increase of 0.13% from the same period last year. On the 7th, Jingdian announced that its revenue in July 2015 was 2.11 billion yuan (equivalent to RMB 414 million), an increase of 10.07% from the previous month and a decrease of 24.23% from the same period of last year. The accumulated revenue for January-July 2015 was 155.26. 100 million yuan (equivalent to RMB 3.084 billion), a decrease of 9.48% compared with the same period last year
Piston is a reciprocating movement in the cylinder body of an automobile engine.
1. The basic structure of the piston can be divided into top, head and skirt. The top of the piston is the main part of the combustion chamber, and its shape is related to the selected combustion chamber form.
2. Gasoline engines mostly use flat-top pistons, which have the advantage of small heat absorption area.
