Hello Physics Forums! After almost a year of haggling and research, I think I have successfully made a engine simulation spreadsheet! I have simulated the Nissan KA24DE Engine with two different cam profiles:
As far as I'm concerned, there is still a lot of work to be done. But I am very happy with the results so far. On the downside, The cylinder pressure function needs to be tweaked a bit, but I just wanted to share my findings so far with the physics forum!
