“…In recent years, the environment and climate change, energy security and other issues have become increasingly prominent, energy-saving emission reduction work has become one of the important work of the government [1,2,3,4]. As one of the main sources of energy consumption and pollutant emissions, the traditional automobile needs to develop the technology to reduce energy consumption and emissions [5].…”

Abstract. Objective: To study the technology of auxiliary motor starting and stopping of the direct injection gasoline engine, and analyze the effect of the idle start stop system and oil saving energy. Method: the fuel saving effect analysis of the fuel saving effect of the system is analyzed by the multiple model. Process: we in the downtown and suburban stop system to open and close the NEDC fuel consumption record results, typical conditions stop system NEDC drive cycle fuel saving effect curve analysis, and instantaneous fuel consumption curve comprehensive comparative analysis. Conclusion: through data analysis, we can know that the average vehicle parking time is more than 9S, the system can reduce the fuel consumption of vehicles; for these two models, starting fuel consumption is high.

“…If bounds overlap, more branches have to be 168 traversed to process a query, which reduces an index's efficiency. In Oracle Spatial, the implementation 169 of the R-tree index stores the tree structure into a table and selects a node using internal SQL statements 170 while each node is visited (Kothuri, 2002). For that reason, query processing using an R-tree index in 171…”

“…Database access methods support data sets that exceed in-core capacity. Many temporal access methods (TAM) and spatial access methods (SAM) are available and are now implemented in temporal [4] and spatial databases [5]. A large number of spatial-temporal access methods (STAM), which tightly integrate time and space, have been developed [6] and many domain specific STAMs have been developed in computer graphics and imaging, robotics, CAD and GIS [7][8] [9].…”
