The animation is very vivid and enough info is conveyed through it to get good understanding of the 4 stroke principals. I think this would be a blessing for anyone wanting to learn about ìnternal combustion engines, or anyone trying to teach the theory. The fact that it's free, and has no adds is mind blowing. I look forward to seeing more. Great work guys!

This can be expanded by so much! I love the idea and the style of this. But the developers should really add more to know about. For example "what happens when engine overheats" "what's inside the engine motor" or just make more educatings about automobile parts like gearbox or the rotor and stator. They should really make a simulation for EVs as well!

This is a simple highly detailed exploration of the 4 stroke gasoline (petrol) engine. It is a very useful learning tool especially for the young, but it will not disappoint adults either. The app is nicely done. I didn't see any ads there definitely weren't any pop UPS. This app does what it says it does and I trust it.

This app is absolutely brilliant! It helped me to understand and visualize the operation of four strokes in a car's engine clearly. I want to have more of these moziak3D apps. It's more useful to me, and I wish I'd be in the course of my dream career.

This App is absolutely great. I run it on my Android Phone and it seems to work very well and really enlightened me with ideas on how the engines actually work. It was really amazing as I can actually see how the different coordinated parts functions by basically obeying the laws of Thermodynamics and General Newtonian Mechanics as a whole. Great Job Developers🙏💪😍

Nicely created and get to notified very clear regarding the every engine or body parts of a car..and most interesting part is we can easily fix all the problem issues..if there will be more options description in details then we can easily fix the minor problem issues instead going to garages then it suppose to be very nice..so all I can say is this 3d option is awesome..so thumps up ..and looking further with more description..thank u guys...

Good in terms of engineering and educational use. It opens mind to knowing vehicle operations and dynamics. I recommend this, after all, they might try for sport RR V-tech cars and other parts such as turbo and super chargers, spoiler, windbreaker and rear diffuser operations in vehicle technology.

Really nice app to show someone to better understand how engine works. I'm little disappointed that there isn't anything else except engine. It would be cool if there was also how gearbox and clutch works and brakes also.
