Summary:

Model based calibration is extensively used by the automotive OEMs (Original Equipment manufacturers) because of its correlation accuracy with test data and freezing the operating parameters such as injection timings, EGR rates, fuel quantity et cetera The prediction of Brake specific Fuel consumption (BSFC), Exhaust and intake temperatures are very close to test data. The prediction of Brake specific NOx is directionally reliable with acceptable tolerance. The physics-based simulation aids in predicting the extrapolated performance considering use of same hardware configuration and this paper focuses on use of 1D Simulation using GT-POWER to accommodate the working of differential stroke piston engine modeling (D-Cycle) and predicting the performance in comparison to the existing conventional ICE (Internal Combustion Engine) for the similar configuration (id est, Same bore, intake manifold, exhaust manifold)This paper explains how 1D Performance simulation was performed using GT-POWER to maximize the combustion efficiency and power/torque demands using a D-Cycle mechanism (id est, all 4 strokes are completed in one revolution) exploiting deficits of a conventional 4-stroke engine, thereby optimizing power output, and reducing emissions, also better low-end torque in D-Cycle improves Tractor Drivability and field performance. Furthermore, appropriate cam geometries ensuing specific application of puddling, tillage et cetera are generated which can be accommodated without major architectural design changes. Exhaust, heat transfer, pumping, frictional losses and volumetric efficiency are analyzed
