Week-11 : Discretization of 3D intake manifold using GEM-3D

1.For the already Build electric vehicle model in the tutorial section of the GT suite change the below given parameters as such, Increase the Vehicle mass by 50%. Increase the Drag coefficient by 5%. Compare the results for the traction motor power without changing the drive cycle.   SOLUTION: The SERIES-PARALLEL…

1. Tutorial- single cyl DI add case 2 with discretization length 0.1 mm for intake runner and compare with default case 1 Parameters-Torque, BSFC, max cylinder pressure simulation time ENGINE LAYOUT OR MODEL:   CASE SETUP: PRESSURE VS CRANK ANGLE PLOT: MASS FLOW RATE VS CRANK ANGLE PLOT: PERFORMANCE PARAMETERS:…

1.TUTORIAL 9: MODEL: 4 CYLINDER GDI ENGINE. 4 STROKE, TURBOCHARGED ENGINE FRM CONVERSION: To reduce the time period by converting from the detailed model to the fast-running model. FRM CONVERTER : Total 8 steps are shown in the tutorial which reduces the high fidelity model which consumes more time to less time by taking…

1. Different types of Turbochargers: Single turbo-charger Twin turbo-charger(sequential) Twin scroll turbocharger Variable Geometry turbocharger(VGT) Variable twin-scroll turbo-charger Electric turbocharger Wastegate turbocharger Examples of turbochargers in GT POWER: The snaps of the different examples…

1. The SI v/s CI Engine parameters are compared and the respective differences are being listed accordingly: The input specifications vary and therefore the output is also different for each setup. The 3600 RPM was set for both engines and the bore diameter was different as 100 mm and 86 mm for CI and SI engine respectively.…

1. Run the case at 1800 RPM and the following parameters are noted as below:       RESULTS : PLOTS AND TABLES: output values: air flow rate = 24.6 kg/h BMEP = IMEP - FMEP = 10.61-1.13 = 9.48 bar BSFC = 239.2 g/kW-h In-cylinder pressure = 48.89 bar     2. Run the case at 3600 RPM and noted down…

1. The GT-SUITE has the following modules/ applications as listed below: Engine Performance and Acoustics: The NVH characteristics and its acoustics are analyzed and studied to damp the noise and vibration due to the engine and its effect on the performance. Exhaust Aftertreatment: It is used to reduce harmful gases…
