Description and Specification for Lab Tenders
Computerized Variable Compression Ratio Diesel Engine Test Rig.
The setup consists of single cylinder, four stroke diesel engine
connected to dynamometer for loading. It is provided with necessary
equipment and instruments for combustion pressure, and crank-angle
measurements. These signals are interfaced to computer for
P- & P-V diagrams. The set-up also consists of air
intake, fuel measuring unit, temperature measuring unit and exhaust gas
calorimeter with temperature measurement system. An arrangement is
provided for changing the compression ratio of the engine by increasing
the clearance volume of the engine. The setup enables study of engine
performance for brake power, indicated power, frictional power, BMEP,
IMEP, brake thermal efficiency, indicated thermal efficiency, Mechanical
efficiency, volumetric efficiency, specific fuel consumption, A/F ratio
and heat balance. The educational software and data logging package has
been developed for this unit. It is compatible to interfacing unit. It
provides a comprehensive educational software environment within which
the investigations can be performed. Interfacing the set up with
computer using software can do the real time data acquisition. Data can
be transferred in Excel Files for further calculations, plotting graphs,
printing etc. Sample readings can be tabulated according to requirement
of experiment under study and results obtained can be compared.
