Week 2 : Basic Calibration of Single cylinder SI-Engine

Aim:

1.To Run the case at 1800 rpm and list down important parameters

• air flow rate
• BMEP
• BSFC
• In-cylinder pressure

2. Increase the power output at 3600 rpm by 10%.

Case Setup:

1.1800 RPM

The SI engine model is imported from the examples and the rpm pf engine is set to 1800.

Result for 1800 rpm:
