                 Output

                 In this  IC Engine  Valve  Model activity, when  the  battery  is powered,  the

                 mechanical components simulate the opening and closing of the valves in an
                 engine. This shows how valves work in a real engine to regulate the flow of fuel
                 and air for combustion.


                 Concepts

                 1.  Engine  Mechanics:  You  will  explore  the  basic  functioning  of  an  internal
                    combustion engine. The activity shows how engine valves open and close in

                    a controlled manner, helping regulate the fuel and air mix, which is critical
                    for engine operation.

                 2.  Controlled  Motion:  The  activity  demonstrates  how  mechanical  systems
                    are used to control precise movements, such as the opening and closing
