Guiding students through a major component of automotive power, this video summarizes the design and construction of engine bottom end or short block assemblies. It explains how bottom end parts are made and illustrates exactly what they do inside an engine, while comparing and contrasting various part designs. Configurations for the cylinder block, crankshaft, connecting rods, bearings, and pistons-including detailed explanations of part movement and functions-are explained with the help of crystal-clear narration and easy-to-understand graphics and animation. After viewing the video, automotive students will be better equipped to understand engine operation and to analyze part failure when servicing an engine. Correlates to all National CTE Organizational Standards (including the provisions of the Perkins Act).
