Product Description

The setup consists of single cylinder four stroke CRDI VCR (Variable Compression Ratio) 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 stand alone 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 engine cooling water and calorimeter water flow measurement.

CRDI VCR engine works with programmable Open ECU for Diesel injection fuel injector common rail with rail pressure sensor and pressure regulating valve crank position sensor fuel pump and wiring harness. The setup enables study of CRDI VCR engine performance with programmable ECU at different compression ratios and with different EGR. 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.
