Fully assembled, easy to use: Fire the , continue to flip the flywheel until the machine can run itself. No need to add .
This model can clearly show the movement of and piston, helping students to deeply understand the internal and external combustion engines. model for experimental teaching and researching.
Fine polished stainless steel body, solid wood base, fine , all metal hot cylinder & , - materials combine into a delicate & model. Nice choice as a gift.
