EP 04 COMP ENGINE TEST SETUP THREE CYLINDER FOUR STROKE, PETROL

(COMPUTERIZED) DESCRIPTION

 

The setup consists of three cylinder, four stroke, Petrol (MPFI) engine connected to eddy current / Hydraulic type dynamometer for loading. It is provided with necessary instruments for combustion pressure and crank‐angle measurements. These signals are interfaced to computer through engine indicator for Pθ−PV diagrams.

Provision is also made for interfacing airflow, fuel flow, exhaust temperature and load measurement. The set up has stand‐alone panel box consisting of air box, fuel tank, manometer, fuel measuring unit, transmitters for air and fuel flow measurements, process indicator and engine indicator. Rotameters are provided for cooling water and calorimeter water flow measurement.

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. Labview based Engine Performance Analysis software package “Vishleshan” is provided for on line performance evaluation.

SOFTWARE

“Vishleshan” is a Labview based powerful engine analysis software developed by Mass International for engine performance monitoring system. “Vishleshan” can fulfill most of the engine testing application needs including monitoring, reporting, data entry, data logging. The software evaluates power, efficiencies, fuel consumption and heat release. It is configurable as per engine set up. Various graphs are obtained at different operating condition. While on line testing of the engine in RUN mode  Necessary      signals    are    scanned,   stored     and presented in graph. Stored data file is accessed to view the data graphical and tabular formats. The results and graphs can be printed. The data in excel format can be used for further analysis.
