This is an update of my original i4 engine i made a little while back.

instead of it cranking over with the motor directly it now has a dedicated starter motor, i also used the grid and layer settings to make it look better than the last one.

the same "firing" order from last time 1-3-2-4.

same controlls as well, s to unlock the engine and d to crank it over.

use the box labled speed control to control the engine speed.
