"3D Engine Auto +" provides information, visualization and working animation on engine 3d and other car mechanisms in 3d. A 3D interactive model helps to visualize the car engine and other mechanisms like "Suspension", "Steering", "Transmission","Differential" from all sides. Models can be rotated, enlarged and panned.

1. Enable/disable 3D parts to see the parts which exactly you want to view.
2. Information of each 3D engine parts and other mechanism. The Information is categorized under the following:
a) Introduction of the part
b) Construction of the part
c) Working of the part
d) Material and Dimensions of the part
e) Types of part
f) Other Applications of the part
g) Extra Information related to the part

8. Working Animation of each 3D Model.
9. Rotation and Scale Sensitivity of the 3d model can be controlled.

Usage and Navigation:
1. Rotate the scene by dragging your fingers over the model.
2. Zoom the model in and out by pinching with your fingers.
3. Select the focus mode, and focus on a particular part in a mechanism.
4. Toggle check/uncheck the part to enable/disable them.
5. Reset the camera to get the initial view of the model.

Note: Currently, the app is in English language only

This is a must have app for engineering students and high school students who are interested in learning about how car moves and how the mechanism works.

Paid version still displays ads.

Paid for ad-free, but ads are still displayed. The ads continue to pop up, so not worth upgrading. When I touch the settings button the app immediately crashes.
