The setup shall consists of single cylinder, four stroke, CRDI VCR engine connected to eddy current dynamometer and provided with necessary instruments for combustion pressure, crank-angle, airflow, fuel flow, temperatures and load measurements. All signals are interfaced to computer through high speed data acquisition device. The panel box will consist of air box, twin fuel tank, manometer, fuel measuring unit, transmitters for air and fuel flow measurements, process indicator and piezopowering unit, Rotameter for engine cooling water flow measurement. CRDI VCR engine shall work with programmable Open ECU for Diesel injection, fuel injector, and common rail with rail pressure sensor and pressure regulating valve, crank position sensor, fuel pump and wiring harness. The  setup would be enable the study of CRDI VCR engine performance with programmable ECU at different compression ratios and with different EGR.

Engine performance study shall include 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. Engine Performance Analysis software package Engine software will be provided for online performance evaluation.
