There are several different ways of visually accessing the combustion chamber in an internal combustion engine. Optical access is provided through a 20-30mm length fused silica liner and a sapphire window in the piston crown. An extended piston allows a 45° mirror to be located between the upper and lower piston crowns allowing illumination or viewing into the cylinder from below. A maximum engine speed of 1000 rpm can be achieved through the use of light weight materials for the piston components and the use of primary and secondary balance shafts in the crankcase. The piston is manufactured from aluminum while the piston crown is made from titanium, chosen due to the similarity in thermal expansivity between titaniumand sapphire.

This test rig is used to great advantage when introducing students to the vapour compression refrigeration cycle. The test rig is portable trolley mounted, hosed on a MS frame tube with wooden platform & front panel, finished by lamination to give elegant finish.  Following are some of the test that can be carried out using this Rig. To study the vapour compression refrigeration cycle To calculate Co-efficient of performance (COP) actual and theoretical. To study the actual refrigeration effect against varying load  (optional At Extra Cost) Determination of cycle efficiency

This test rig is used to find the performance and combustion parameters of Variable Compression Ratio Petrol Engine. The compression ratio of the engine is variable from 2.5:1 to 10:1.A unique provision is been made to vary the spark timing of the engine.  Wide range of combustion studies can be conducted with the help of this setup. Engine  Combustion and performance parameters like Actual volume of Air, Volumetric Efficiency, Specific fuel consumption (SFC), Brake Thermal Efficiency, Brake power, Heat Balance chart, mechanical efficiency, Frictional Power , indicated Power, PV and P-θ diagrams, Mass Fraction Burnt Angle, Estimated End of Combustion Angle (EEOC), Gross IMEP, Maximum Heat Release Rate, Maximum Heat Release rate crank angle, Maximum pressure rise rate, Maximum pressure rise rate crank angle, Maximum pressure, Maximum pressure crank angle, Start of Combustion, Total heat release, Ignition delay, ignition duration can be studied.

To study the COP in various Valve opening position. Precise positioning for optimal control of liquid injection. EEV are designed for HFC/HCFC conditions including R22, providing 45.5 bar (659.9 psig) working pressure. Design providing bi-flow operation as well as solenoid tight shut-off function in both flows Directions at MOPD 33 bar (478.6 psig). EEV are available with straight as well as angle ODF solder connections. EEV is equipped with AST-g MKII actuator with M12 connector for cable connection. Cable and connector assemblies as accessories. For manual operation and service of ETS valves an AST-g service driver is available.

This equipment shows how a flat plate solar energy collector works. It allows students to measure and find the efficiency and heat losses of a flat plate solar energy collector. The Flat Plate Solar Energy Collector is similar to those used for heating swimming pools and domestic hot water.

This apparatus enables the student to study the characteristics of composite structures and its heat transfer ability across the composite walls by altering the combination of slabs. The apparatus consists of three slabs of different materials of same thickness. The slabs are brought together in contact. The three slabs are brass, M.S and asbestos. One surface of the slab is electrically heated and the other end is cooled, .the temperatures of the slabs are measured using thermocouples and are indicated by temperature indicator. The power Input to the heater is measured by Voltmeter and Ammeter.
