Product Description

The setup consists of single cylinder four stroke VCR (Variable Compression Ratio) Research engine connected to eddy current dynamometer. It is provided with necessary instruments for combustion pressure crank angle airflow fuel flow temperatures and load measurements. These signals are interfaced to computer through high speed data acquisition device. The set up has standalone panel box consisting of air box twin fuel tank manometer fuel measuring unit transmitters for air and fuel flow measurements process indicator and piezo powering unit. Rotameters are provided for cooling water and calorimeter water flow measurement.

In petrol mode engine works with programmable Open ECU Throttle position sensor (TPS) fuel pump ignition coil fuel spray nozzle trigger sensor etc. The setup enables study of VCR engine performance for both Diesel and Petrol mode and study of ECU programming. Engine performance study includes brake power indicated power frictional power BMEP IMEP brake thermal efficiency indicated thermal efficiency Mechanical efficiency volumetric efficiency specific fuel consumption Air fuel ratio heat balance and combustion analysis.

EngineSoft is Labview based software package developed by Apex Innovations Pvt. Ltd. for engine performance monitoring system. EngineSoft can serve most of the engine testing application needs including monitoring reporting data entry data logging. The software evaluates power efficiencies fuel consumption and heat release. 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 data in excel format can be used for further analysis.
