4-cylinder inline engine

This is my design of the 4-cylinder inline engine (flat plane version) with timing belt. There is still some work to do but it works.

Need invincible mode and infinite ammo to work.
To start the engine push the "H" button.

Another version (light) of the same engine powered with shrapnel cannon.

Need invincible mode, infinite ammo and 'Better Torches Mod' to work.
To start the engine push the "i" button... ENJOY :)

P.S.: I plan to make similar test but first i wanted to make my engine perfect so i think it's high time to post my final version of it... it's ready to use ;)
