Single Cylinder IC Engine in CATIA V5

I tried this model and done it in the CATIA V5. I used Bottom - up method of Assembly designing. I used parts like bolts, piston, piston pin, crank shaft, connecting rods, engine cover, oil pan, nuts etc and made this model separately in part design and assembled in Assembly workbench. I try to make more models like this and make a path to my professional design career.
