An anodised aluminium disc used as crank is mounted on ball bearings on a white plate. This disc has a pointer so that the input angle can be exactly read on the integrated angle measuring scale. The crank pin can be set at different radii on the disc. The experimental unit is used to generate and investigate pure harmonic reciprocating motion. The slider crank is attached to the crank pin on one side. The model is equipped with plastic feet and is placed on the laboratory table for the experiment. Two handles make the unit easier to carry. On the other side the pin is mounted in straight guide that is fitted with a ruler to allow the output stroke to be read off with precision.

The Set of Plate Weirs experimental set-up includes 4 different weir plates that can each be placed on a weir carrier and then fitted to the base of the channel. Tubular seals made of plastic inserted in slots on the side of the weir plates complete the experimental set-up. They are used for measuring the flow rate, whilst sharp edged aerated overflow can be investigated on the plate weir. The weir plates and weir carrier are made of PVC. The weir plates represent an aerated plate weir, a Thomson weir, a rectangular thin plate weir, and a Cipoletti weir. Apart from the aerated plate weir, all of the weirs mentioned are measuring weirs.

The engine consists of a large vertical cylinder with heater to generate hot gas. Twin cylinders above the hot gas cylinder generate power. The hot gas cylinder head can be cooled by water from a cooling system. The Stirling Cycle Hot Air Engine Twin Power unit is for demonstration of stirling cycle hot air engine principles. All cylinders are attached to a common shaft. Heater to the hot gas cylinder can be varied. The advantage of this design is the ability to bring the engine to operating condition in a short time. Instruments are provided for measurement of input power and output power.
Experiments:
Output and efficiency vs speed for a given input power.
Torque vs speed for a given input power.
ffect of hot gas cylinder head cooling on efficiency.
As all the parts of the injector are multiple laser-welded, it is not possible tocutaway these parts any further. The benefitof these injectors is that they switch extremely quickly and thus injectminimum quantities of fuel, which makes multiple injection (3) possible.
The followingcan be seen:
Electrical connections for voltage supply to the piezo-actor module
Cutaway injector housing and interior housing
Teflon ringfor sealing in the cylinder head
Fuel flow (high pressure)
O-ring toseal the leakage line
Nozzle module
Coupler module.
