Technical Teaching Equipment
The Crank Mechanism "MBI", enables the students to simulate the operation of a classical piston mechanism easily. It represents the piston
mechanism of an automobile perfectly; cylinder and crankshaft of a vehicle.
The Crank Mechanism is used in the automobile industry, shipbuilding industry, etc.
The Crank Mechanism "MBI" is a unit designed to observe, study and record the motion of a crank and the forces involved in a simple
engine mechanism.
The piston is linearly displaced through a cylinder with the aid of a guide.
Bearings are coupled to the connecting rod so that friction is kept to a minimum.
There is a protractor attached to the crank, which can be rotated on the beam balance arm and locked in any predetermined angular
The piston displacement can be measured with a linear scale attached to the piston guide. The piston can be fitted with removable weights
to change the piston mass.
The crank effort can be determined by attaching weights to the beam balance arm.

Bench-top unit with adjustable legs.
Anodized aluminum structure and panels in painted steel.
The MBI unit mainly consists of:
Piston and guide with graduated scale: piston stroke: 70 mm.
Connecting rod made of stainless steel.
Shaft of the system and counterweight made of stainless steel.
Measuring disc.
Beam balance arm.
Set of weights to add to the piston:
Mass of 1 kg, 1 unit.
Mass of 0.5 kg, 2 units.
In order to carry out some of the practices with MBI unit, a “B” type Set of weights is required. (See “Required Accessories” section).
Manuals: This unit is supplied with the following manuals: Required Services, Assembly and Installation, Starting-up, Safety, Maintenance
and Practices manual.
6.- Comparison of the piston displacement value theoretically and
1.- Determination of the crank effort.
2.- Balancing of the crankshaft.
Experimental relationship between turning moment and
crankshaft angle.
3.- Measurement of the piston displacement.
4.-Experimental relationship between piston displacement and
crank angle.
8.- Theoretical relationship between turning moment and crankshaft
5.- Theoretical relationship between piston displacement and crank

MBI/ICAI. Interactive Computer Aided Instruction Software System:
Whit no physical connection between unit and computer (PC), this
complete software package consists of an Instructor Software
(EDIBON Classroom Manager -ECM) totally integrated with
the Student Software (EDIBON Student Labsoft -ESL). Both are
interconnected so that the teacher knows at any moment what is the
theoretical and practical knowledge of the students.
Instructor Software
-ECM. EDIBON Classroom Manager (Instructor Software).
ECM is the application that allows the Instructor to register students, manage and assign tasks for workgroups, create own content to carry out Practical
Exercises, choose one of the evaluation methods to check the Student knowledge and monitor the progression related to the planned tasks for individual
students, workgroups, units, etc... so the teacher can know in real time the level of understanding of any student in the classroom.
Innovative features:
User Data Base Management.
Administration and assignment of Workgroups, Tasks and
Training sessions.
Creation and Integration of Practical Exercises and Multimedia
Custom Design of Evaluation Methods.
Creation and assignment of Formulas & Equations.

ESL is the application addressed to the Students that helps them to understand theoretical concepts by means of practical exercises and to prove their
knowledge and progression by performing tests and calculations in addition to Multimedia Resources. Default planned tasks and an Open workgroup
are provided by EDIBON to allow the students start working from the first session. Reports and statistics are available to know their progression at any
time, as well as explanations for every exercise to reinforce the theoretically acquired technical knowledge.
Innovative features:
Student Log-In & Self-Registration.
Existing Tasks checking & Monitoring.
Default contents & scheduled tasks available to be used from
the first session.
