Week 2 : Basic Calibration of Single cylinder SI-Engine
Aim : In this assignment we need to setup the case for the single cylinder SI engine running this at 1800 rpm and finding the below calues from the report.
- air flow rate
- BMEP
- BSFC
- In-cylinder pressure
In the case setup the speed is set to 1800 rpm,
the solution is ran using the default configurations and the report obtained from GT post
|
Air flow rate |
24.6 kg/hr |
|
BMEP |
9.5 bar |
|
BSFC |
239.2 g/KW-h |
|
In-cylinder pressure |
48.89 bar |
for increasing the BP by 10% we increase the bore of the cylinder from 86mm to 89 mm
and compare it eith the default bore and speed
by using creating the parameter for bore , in case set up as follows
and next we run this solution and compare the table data in the results
and the BP value is increased by 10%
from initial BP of 16.7 KW to 18 KW
