Development of Visual Test System of Heated Components’ Temperature Field for a Marine Two-stroke Engine

In order to display visually the heated components' temperature field in the combustion chamber for marine two-stroke engine and improve measurement efficiency, the structural characteristics of the piston, cylinder head, liner and exhaust valve were combined, the layout of measuring points was analyzed, and the temperature test methods with wire and wireless were selected. Three-dimensional (3D) models of the components were established. After dividing the mesh of each heated components, 3D temperature cloud map mapping principle was studied, the temperature signals acquired and communicated were lead to the model through spatial interpolation algorithm, and the visual display of the overall temperature field distribution of the components was realized. At the same time, the truncation planes of each component were created with various functions such as model hiding, splitting, perspective, and picking up sensor points, an intuitive and unique 3D visualization temperature field test system of the components was developed by using the 3D visualization cloud model display.
