The education stand is so designed,
that all functions can be seen from front view and back view, so the
teacher can instruct behind the stand without obstructing the view on the
front side. The cylinder head is build separated and is endued with
distance pieces. Therefore it is also during the operation warranted that
you can see the camshaft and the chain drive in operation. The rail pump
is like in the car, activated by the camshaft. The spark plugs and the
spark coils are located outside the cylinder head and are fully
functional. The first cylinder is been cut and shows very clearly the
direct injection and the tumble principle. The education stand has two
floor cupboards in which the electric control cabinet and the tank with
impounding basin are located. All components, which are necessary for the
real operation are original components and can be activated with rocker
switches. For every component one potentiometer is mounted, which is
activated in the opposite direction as the rocker switch and allows
optional adjustment. Types of control and redundancies become visible.
Furthermore the original OBD interface is lead through to have the
possibility to connect all standard testers. Real garage situations are
simulated by a failure switching box and create new situations for the
apprentice. The drive comes from a 400 V three-phase ac motor. A frequency
converter provides for the required ranges of speeds for the cylinder
head. All parts are labelled with name and the respective symbol. The
education stand is mobile through four brake able roles with a diameter of
125 mm. The panel comes with a mushroom-type palm-button, ignition switch,
ignition control lamp and OBD-interface. All frame parts are of high
strength, extruded aluminium sheath.
