Computerized Variable Compression Ratio Diesel Engine Test Rig

Model No. AMEL008

Description

DESCRIPTION:-  

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.
