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.

The continuing sluggish macroeconomic situation has a direct impact on the speed at which electronic products are consumed and renewed. It also leads to lower expectations for the company's future market, and it has reduced electronic product inventories.
Since the international financial crisis in 2008, the global economic development has been shrouded in the shadow of the crisis. Although the domestic and foreign semiconductor market rebounded strongly in 2010, it was only a flash in the pan. In 2011, affected by the economic downturn, the global semiconductor industry was US$299.5 billion, and sales increased by only 0.4% from 2010. Although people have strong expectations for market expectations for 2012, the global semiconductor market continues to be sluggish in terms of performance in the first half of the year, and the industry has generally maintained a conservative attitude toward market growth throughout the year. In the first half of 2012, the global semiconductor industry was US$142.85 billion, a year-on-year decrease of 5.1%, and the market expectations for the third and fourth quarters were generally low. Although WSTS estimated at the beginning of June that global semiconductor market sales will exceed US$300 billion in 2012, the market will achieve a growth of 0.4%, which is in line with the market growth rate in 2011. However, from the current market performance, the global market still maintains a negative growth trend. And there is a downward trend from month to month. It can be seen that the global semiconductor market is likely to experience negative growth in 2012, becoming the second negative growth since the 2009 financial crisis.
In 2012, the global macroeconomic situation was still cloudy. The European sovereign debt crisis has not been resolved for a long time; the effect of the QE3 economic stimulus in the United States is not obvious; the overall growth in the Asia-Pacific region has slowed down. The continuing sluggish macroeconomic situation has a direct impact on the speed at which electronic products are consumed and renewed. It also leads to lower expectations for the company's future market, and it has reduced electronic product inventories. In the first half of 2012, the overall consumption capacity of global electronic products has been greatly reduced, and the global semiconductor market has thus lacked the direct impetus for growth. In addition, although the Ultrabook market has seen significant growth this year, the overall trend toward the weakening of integrated circuits by traditional PCs has not changed. Although portable smart mobile devices represented by smart phones and tablets have shown strong growth momentum in recent years, it is still difficult to replace PCs as the main growth driver for the sustained and stable semiconductor market in the short term.
