At present, China vigorously promotes the use of the pipeline robots, for the maintenance of the oil and gas pipelines by the unique characteristics of the robots. In this paper, the author carries out the detailed analysis on the current situation of the development of the pipeline robots in the oil and gas storage and transportation industry, and compares the different applications of the pipeline robots at home and abroad. Starting from the principles of the operation of the robots, the author analyzes the characteristics of the different types of the robots, and combined with the existing conditions of the oil and gas storage and transportation in our country, the author tries to find the most favorable way of the working of the pipeline robots, to continuously improve the development of the oil and gas storage and transportation industry using the robot technologies.展开更多

Also large oil reliant suppliers of such goods as plastics, heating oil and construction material would be at a loss for the necessary raw materials. Petroleum reliant power plants would be out of production and the transportation industry would have no gasoline for its vehicle. Apart from this, there is a big need for the protection of the environment. Therefore, it is important to replace the petroleum with non fossil fuels or ones that can be made to last a lot longer, such as the renewable fuels that can be used in the engines and are friendly to the environment too. This paper examines the use of diesel-soy oil mixtures and diesel-olive seed oil mixtures in a four-stroke diesel engine. For those mixtures the gas emissions of carbon monoxide （CO）, hydrocarbons （HC） and nitrogen monoxide （NO） are being measured and the fuel consumption is also examined.展开更多
