Q:-Explore tutorial number 9 and write a detailed report (50 marks) Ans:- Tutorial 9 shows the case setup given below is GDI SI engine FRM  Model. It is Gas direct injection model inwhich fuel is injected into comsution chamber during compression Stroke to make Homogenous mixture. It is fast running model so…

Q:-List down different TC and locate examples from GT Power Ans:- Turbocharger is used to increase boost Pressure of air intering into Cylinder. It increase air density of inlet air and more air provided for combustion.It increase 15% of Power output of Engine There are three type of Turbocharger configuration as…

1.Compare SI vs CI and list down differences (assignment no 2-SI) Ans:- The operating principle of SI Engine and CI Engine is totally Different.   SI Engine  CI Engine (1) SI Engine is Spark Ignition Engine i.e there is spark Plug to Ignite mixture of Air and  Combustion Fuel Gasoline. CI Engine is Self…

Q.Run the case at 1800 rpm and list down important parameters (20 Marks) air flow rate BMEP BSFC In-cylinder pressure   Ans:- The case setup is single cylinder SI Engine as shown Below. This case is load from Tutorial -Engine Performance-1Cyl SI Engine.   The intial Inlet condition of air is as shown below Pressure…
