"3D Engine Auto +" is a detailed application offering information, visualizations, and working animations of car engine 3D models and various car mechanisms. It presents interactive 3D models allowing users to explore car engines, suspensions, steering systems, transmissions, and differentials from all angles. Users can manipulate the models by rotating, zooming, and panning.

This app features the ability to enable or disable specific 3D parts for focused viewing and detailed information on each part, including construction, working principles, materials, dimensions, types, and applications, along with working animations for each 3D model. It also provides control over the rotation and scale sensitivity of the models, making it an essential tool for engineering and high school students interested in understanding car mechanics.
