The engine is directly coupled to the dynamometer using an inertia matched drive shaft. All rotating parts are protected by fixed guards. The test bed incorporates a robust mounting frame to which both the engine and dynamometer are fitted. The drive shaft guard is interlocked with the Emergency Stop circuit to prevent the engine from use when the guard is removed or open. The frame is fitted with wheels to allow the test bed to be easily moved.

A comprehensive instrumentation package, data acquisition and computer control of facilities allows experimental analysis of engine performance parameters such as power, torque, speed and efficiency under various operating conditions, controlled and measured by a dynamometer and ancillary instrumentation. Multi-Cylinder Automotive Engine Test Bed has been developed to provide a facility for the practical demonstration of internal combustion engine technology. Display of all test parameters is via a remote PC screen, coolant & lubricant temperature is closed loop controlled to temperatures entered on the PC. Coded engine connections ensure correct connection of services & instrumentation when the engine is changed. A remote control console is provided to start/stop the engine with 10 turn potentiometers to control engine load & speed. Cussons offers two engine options that are sub-frame mounted to allow rapid engine changes.

The system comes complete withinstrumentation, including rpm measurement, torque (from which power can becalculated), airflow and exhaust temperature. This multi-purpose test rig is designed to accept a series of gasolineand diesel engines available separately. The utilises an eddy-current dynamometer to provide avariable load on the engine, enabling the characteristic power and torquecurves to be reproduced in the laboratory dependent upon which sensor optionsare ordered. This provides real-time monitoring of the varioussensors, with a wide range of data logging and graphical display options. Both the dynamometer and throttle can be controlled electronically, which makesinstallation into a closed test cell straightforward, and enables remoteoperation.
Other optional sensors can bepurchased to further enhance the teaching capabilities of the includingcylinder pressure sensors and fuel consumption.
The unit is designed to be linked to the users computeror touch screen, linked to supplied software with sophisticated control anddata acquisition.
The whole system is designed to be linked to a computerusing the software provided.

Internal pressure is applied to the cylinder by mean of a hydraulic hand pump. Pressure in the cylinder is indicated on a pressure gauge. A hand screw is attached to one end of the frame to operate a piston on one side of the cylinder. Thin Cylinder Experiment is used for studying the stresses in a thin wall cylinder. The strain gauges are fixed onto the cylinder at different angles. Each strain gauge is wired to form a full bridge with temperature compensation gauge and zero adjustment in a bridge box with strain gauge indicator. A thin wall aluminum alloy cylinder is mounted on a rigid steel frame. By applying the hand screw, only circumferential stress occurs on the cylinder or both circumferential and axial stresses occur.
Experiments:
Measurement of strains and stresses under internal pressures.
Comparison of theoretical stresses and strains with experimental values.
Determination of Youngâ„¢s modulus an Poissons ratio.
Demonstration:
Pressurebuild-up
Function inthe event of a failure of any brake circuit
Sliding thepressure rod piston
Differentialand tracking bore function
Closing thepressure chamber.
The student obtains further training in diesel timing, fuel-air mixture measurements and injector performance. Single Cylinder Diesel Program provides advanced experiences in operating a single cylinder diesel engine measuring torque and speed. Any malfunction of the engine and loss of power is measured by an electric dynamometer.
The program includes a Electric Dynamometer, coupled to a Diesel Engine on a baseboard together with Air and Fuel flow meter set-up and interconnection system running on biodiesel. The data aqcuistion system can also be added to the basic Single Cylinder Diesel Program to record data and compare results. Horsepower and Torque can be viewed on screen in a visual graph. Information like can be graphed, and compared on a computer, then saved or printed. Single Cylinder Diesel Program is a powerful training aid for any student learning diesel.
