I'm engineering student. I've got this project from my teacher.

The problem is I "never" use MATLAB before and I try to search some informations about Diesel Cycle for MATLAB many times on internet but I can't understand.

Please help me to solve this project, I really need some helps here.

Thank you very much.

PS. Sorry for my bad English

"Isentropic" means "with constant entropy".

As another hint, once the P-V curve is developed, trapz can be used to perfrom numerical integration.

在 MATLAB Online 中打开

Here's a start:

theta = (0:0.1:359.9)';
D = 15;
L = 12;
L_TDC = 1.5;
V_TDC = (pi/4)*D^2*L_TDC;
