This model of a six-cylinder diesel engine is designed to be partially representative and partially diagrammatic. Certain elements, like electrical and oil pathways, are highly simplified, while at the same time representational elements (bolt holes, for example) have been retained to provide a satisfyingly complex, but not visually overwhelming, appearance. The model is shaded with stylized chrome and metal shaders, and has a fine cel shading outline, hearkening to airbrushed automotive illustration.
