Piston pumps are used when high pressures are to be generated. The flow rate of piston pumps is independent of the head and is determined only by speed. Its good suction performance is outstanding. Piston pumps belong to the group of positive displacement pumps. They transport the medium by a reciprocating motion of a piston in the pump working space, called stroke. The stroke creates a suction respectively vacuum effect used to deliver the water. The pulsating pressure curve of the pump can be damped with the aid of the air vessel. Flow rate and head are adjusted via needle valve and overflow valve. The experimental unit is fitted with sensors for pressure and flow rate. The cycle that takes place (intake and discharge of water) can be shown clearly in the p-V diagram. The position of the piston rod is measured by an angle sensor. This allows the determination of the cylinder volume. One pressure sensor measures the pressure at the outlet of the pump, another one measures the pressure in the inside of the cylinder.

Diesel engines work by compressing only the air. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel that is injected into the combustion chamber ignites spontaneously. The diesel engine (also known as a compression-ignition or CI engine), named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel which isinjected into the combustion chamber is caused by the elevated temperature ofthe air in the cylinder due to mechanical compression (adiabatic compression).

The board affords the problems associated to the use of the transistors in the three basic configurations: CE (Common Emitter), CC (Common Collector) and CB (Common Base). The board allows a first approach to the theoretical practical study of the static and dynamic operation of the BJT (Base emitter Junction Transistor), used as a voltage amplifier. Firstly, the bias and the working point stabilization problems are considered. Then, the typical features of the three configurations are analyzed: input resistance, output resistance, voltage gain and current gain. The board is supplied complete with a set of stackable, plug in cables of suitable lengths and colours and with a training manual. In the second section of the board typical applications are studied, such as the bootstrap effect bias and the Darlington connection.
