An engine is a machine designed to convert one form of energy into mechanical energy. Engine Auto Parts is a very important part of car.
The engine is the power source of the automobile. Most of the Car Engine Parts is thermal power plant, referred to as thermal machine. A thermodynamic machine converts the heat generated by fuel combustion into mechanical energy by means of a state change in the working mass.
According to the different power sources, the automobile engine can be divided into diesel engine, gasoline engine, electric vehicle motor and hybrid power.
Common gasoline engines and diesel engines are reciprocating piston-type internal combustion engine, which converts the chemical energy of the fuel into the mechanical energy of piston movement and the external output power. The engine has the characteristics of high speed, small quality, low noise, easy starting and lower manufacturing cost, large compression ratio, high thermal efficiency, better economic performance and emission performance than gasoline engine.

Hangzhou, Zhejiang Province is famous for its water, its name because of water, its beauty because of water, and it is a city that gathers five rivers and waters for rivers, lakes, streams, and seas. Water records the history of Hangzhou and inherits Hangzhou culture.
“To cure water is to build beautiful Hangzhou. To cure the water environment, Hangzhou's paradise on earth's reputation will become even louder.†Xu Liyi, executive deputy mayor of Hangzhou, said that through water control, the people of the city can drink more at ease with cleanliness. The water no longer sees the black water, no longer smells the smelly water, no longer fears that the rain will not be able to return home or water in the home; but also through water control, it will force Hangzhou's industrial restructuring and upgrading, economic restructuring, and make the industry more Excellent development, ecological improvement, let green water Qingshan permanent Hangzhou.
It is reported that Hangzhou has formulated a three-year plan of action for "five waters co-govern," and strives to achieve some tangible benefits that the public can see and enjoy through three years of hard work. At present, the rectification work focused on the treatment of sewage is still proceeding in an orderly manner.
Moving the company and building an ecological environment Hangzhou has created the brand of “the strictest environmental supervisionâ€. In Dingqiao Town, Jianggan District, Hangzhou, there is a river that was artificially excavated called Da Nang Port. One of the large plant ecological belts in the center of the water is like a large lotus flower blooming in the middle of the river. It is very beautiful. Every evening, the crowds of people on both sides of the river have become a good place for Dingqiao residents to walk and catch a cold.
Just a few years ago, Da Nang Gang was a black river. Both sides of the land are occupied by factories. The industrial wastewater discharged from the printing and dyeing factories and the lube oil plants and the domestic sewage of nearby farms are all directly discharged.
Since 2008, Da Nang Port has started a governance plan. According to the length of the river and the party secretary of Dingqiao Town, Hu Qiuteng, 90% of the factories have now moved away from both sides of the river, and domestic sewage has also undergone the transformation of the interceptor and the emission of pollution sources has been controlled. Through the large-scale dredging and purification of aquatic plants, the current water quality has been greatly improved.
An old man walking along the river laughed and said, "In the past, this river was dirty and stinks. We must walk past our noses. Now you look, so beautiful, we don't go anywhere else. Here we are. It's enough to ride cool and play."
The practice of relocating and shutting down the enterprises in Dingqiao Town to make way for water control is only a small part of the work of Hangzhou to create the “most stringent environmental supervision†brand.
The problem is in the water and the roots are on the shore. In order to control the source of pollution, clean up the black and smelly river. Hangzhou has implemented the most stringent access to achieve “zero†approval of the over-the-line projects; implemented the most rigorous monitoring to achieve zero “zero†monitoring; implemented the strictest governance and achieved “zero†tolerance for environmental violations; implemented the most Strict law enforcement, to achieve industry "zero" rebound; implementation of the most stringent system, to achieve a "zero" blind zone of the regulatory system.
Under the background of the Five Waters Co-governance, this year, Hangzhou plans to eliminate 71 waste rivers, a total of 459.8 kilometers; as of the end of April has completed 58 nearly 385 kilometers, invested 15.11 million yuan. The city plans to renovate 193 black-smelly rivers, a total of 665 kilometers; as of the end of April has started 125, start-up ratio of 64.8%, has completed 194.4 kilometers, the completion rate of 29.2%.
The planning and project of the Hangzhou Flood Control Drainage Unit will soon be replaced with new ones. “Come to the city for the people's recognition to be sure to take the opportunity to further intensify efforts to speed up the work progress, so that the people will get real benefits.†This is Hangzhou. Mayor Zhang Hongming's instructions in a letter from the masses.
The residents who wrote this thank-you note came from the Shantoushan community in Hangzhou. Due to the special terrain and long construction period in the Shantou Mountain area, this area has been suffering from flooding for many years. In the future, a 50-cm-diameter drainage pipe will change the current situation of this year.
According to the relevant construction personnel, the transformation of the Brahmin Temple Road started first. The original 5-meter-wide road was dug open and a 50-cm-diameter drainage channel was put down to collect rainwater and domestic sewage. In addition, major roads such as Songcheng Road, Fenghuangshan Road, and Fengshan Road, which are most prone to water accumulation, have also been excavated one after another. The drainage pipes with a diameter of 50 cm are also buried. On the ground floor of Liwan Road, a new 1.5mx1.8m drainage ditches will be constructed to collect the accumulated water into Zhonghe. After the drains and drainage pipes are laid, seven or eight wells will be added to this area for temporary storage of water.
According to the recently announced "Hangzhou Urban Drainage (Rainwater) Flood Prevention Comprehensive Plan", by 2020, Hangzhou's flood control and drainage capacity will be increased to meet the standard of one-time torrential rain in 30-50 years.
“This plan refers to cities in developed countries such as Germany and the United Kingdom, and it is the one with the highest planning standard in years.†Feng Yijun, deputy chief engineer of the Hangzhou Planning and Design Institute, said that in the future, West Lake, Xixi Wetland, Xianlin Wetland, Dingshan Lake, Eight wetlands and lakes, including Jinsha Lake, Baima Lake, and Xianghu Lake, were used as storage facilities. At the same time, flood control measures such as Jianye District, elevation of the ground, inland river management, etc. were proposed, and 106 key drainage and river drainage channels were opened to open up Baishi Port. Three decapitated rivers, such as the Airport Port and Xinkai River.
At present, some facilities have already started construction with the "five waters co-governance" operation. After three years, the flood prevention and drainage system in Hangzhou will change its appearance.
The new pattern of multi-source water supply in Hangzhou will be introduced to the lake and the reservoir. Not long ago, the dumping incident of the Fuyang Hazardous Chemicals Transport Vehicle once again triggered the war of drinking water in Hangzhou. Drinking water security issues have become a major concern for people in Hangzhou.
Faced with questions from the masses, executive vice mayor Xu Liyi said in an exclusive interview with Ben Wang that the tap water in Hangzhou is in line with national standards and the general public can rest assured that they can drink it.
However, he also admits that the source of water for drinking water in Hangzhou is a single and open type. Open water sources have a large range of water catchment, and the safety risk of drinking water exists objectively. In addition, there is currently only a spare water source in the city of Liansha River in Hangzhou, and there is little room for emergency options.
In order to alleviate this contradiction, Hangzhou has been using its brains to think of ways to respond positively and has also done a lot of targeted work. For example, the implementation of the water source protection project will shut down and relocate the 22 polluting enterprises that have been found in the first and second grade drinking water source protection zones; implement the water production process upgrade project, and implement the Xiangfu Water Plant, Jiuxi Water Plant, and the Chishan Water Supply Project. The in-depth treatment and transformation of the factory; promote the construction of the Qiandao Lake water distribution project, and strive to allow Hangzhou citizens to drink thousands of island water at home for three years.
Xu Liyi said that despite the need to allocate water from the Qiandao Lake, it will never relax the water environment treatment of the mother river in the Qiantang River. On the contrary, the work will be further strengthened. At present, the Xilin Reservoir has completed the dam main body filling project, and it can have water storage conditions by the end of the year. By the time the completion of the second water source and the backup water source project, the new pattern of multi-source water supply in Hangzhou will also be formed, and Hangzhou's drinking water safety will also be able to receive more reliable and more effective protection.
Hangzhou “the strictest environmental supervision†new pattern of multi-source water supply will form
