Cylinder is the place where the fuel-air mixture is compressed and burned to convert chemical energy to heat and mechanical energy to make the bike go. Just like in any other internal combustion engine. The engine might have only one cylinder or many. More than four is rare, though.The cylinder is fired by a spark plug which creates a spark electrically from the battery .
It is the cylinder in an engine where the combustion takes place-..in vehicle the cylinder is just above the transmission. think of it as a syringe. the piston moves up and compresses the air fuel mixture and as a result combustion takes place. the piston is then pushed down. this up and down motion of the piston rotates the crankshaft which is connected to the transmission which transmits power to the wheels. there are various configurations of cylinders in an engine. in vehicle have single cylinder, parallel twin, v twin, L twin, inline 4, inline 3, inline 6, v4, flat twin. similarly in cars you get inline 3, inline4, inline6 , v6, v8, v10, w12. the number represents the no. of cylinders and the letter or prefix represents the configuration.

From the family security to the safe city, no family harmony and security can guarantee the harmony and peace of the society. With regard to the application of the security market, efforts will be made to develop civil security in order to truly realize the construction of a safe city. Different from other fields, the security market is centered on industrial users, and civil users only occupy 20% of the market. According to the unique “28 law†analysis, the civilian market is an important goal for future development.
Taking the construction of safe cities as an example, the development of a city's security level has been greatly limited, especially when technology encounters bottlenecks, it is difficult to create greater market value. However, the civilian market is different. Because individual, small shops, and private companies have different security awareness, the market has not yet reached popularity. The saturation period of the civil market is still unknown. As far as technological development is concerned, civil security currently only involves the "standard definition" phase, and "low-cost" high-definition surveillance has not yet been popularized. Intelligent analysis, wide dynamics, low illumination, and so on, for the civilian market, there are some "less than enough", so the technical level has yet to be improved.
The development of industrial applications from standard definition to high-definition surveillance The development of high-definition surveillance was not accomplished overnight. From the initial analog surveillance to digital surveillance, from standard definition monitoring to high-definition surveillance, its development has also been going on for several years; it is the industrial application that promotes high-definition surveillance. development of.
In the construction of safe cities, in order to solve the wiring problem, most surveillance cameras gradually converged to the network, and 3G became the carrier of wireless monitoring. When we ignore immature HD-SDI products, we can say that high-definition monitoring must be networked. In the financial and transportation sectors, strengthening HD surveillance is not only a development of technology, but also a market demand.
Data: From mass storage to cloud storage With the gradual recognition of monitoring equipment, video data has gradually increased, especially high-definition image data has been difficult to manage with conventional storage devices such as DVRs and other hard disk recorders, when massive data cannot be stored this time The emergence of "cloud" storage is undoubtedly the savior of HD surveillance mass storage. The emergence of cloud storage breaks through the performance and capacity bottlenecks of traditional storage methods. This technology can connect a large number of different types of storage devices in the network to form very powerful storage capabilities; the devices in cloud storage are completely transparent to users. Any place can be connected to cloud storage through the network when authorized. It is easy to operate and safe.
Widening the industrial chain stability The development of the large security market involves a lot of content. In addition to the monitoring system, its derivative technology has been fully recognized in various industries. During the Spring Festival, the buzzing two-dimensional code technology was also considered as one of the security measures. After numerous exposures, the Ministry of Railways eventually encrypted the train ticket “two-dimensional codeâ€. In IoT applications, sensors account for 40% of the total, while video surveillance is the most typical application of sensors; under the leadership of the monitoring market, the Internet of Things is also leveraging the development of the "12th Five-Year Plan" by 2015. The overall market size of China's Internet of Things will reach 750 billion yuan. The sensor market in the video surveillance system will also exceed 300 billion yuan. How can security and security in the security market face such a figure?
In summary, driven by the application of the industry, driven by the large security market, video surveillance has been well-developed. In the market, civilized security needs to be further improved. Safer cities and other special areas also need higher-end monitoring and technical support. In terms of technology, high-end monitoring has encountered bottlenecks in development. How to break through the bottleneck period requires various security companies to brainstorm. It is worth noting that the cost-effectiveness of technology and cost is the only magic weapon that has been approved by the market.
Industry-oriented application of security technology continues to introduce new
From the financial, transportation, campus, medical, and even safe cities, the application fields of security industry are constantly expanding. From government projects to civilian security, from railway transportation to medical and health, security is constantly paying attention to people's food, clothing and housing. Obviously, security seems to have come to us from another country "for a moment," and has developed rapidly in an unprecedented fashion. The laymen watched the excitement, knowing that "monitoring" can be either on the road or at home; insiders look at the door and understand that the industrial application has led to the continuous innovation of security technology to meet the diverse needs of different users.
