Equation 4でのTorqueの求め方の出典を教えてください

The formula to calculate the torque produced by the engine in this specific example, is given in Equation 4, as indicated by the red box. This equation is most likely implemented in Simulink using the already-obsolete 'Fcn' block, as shown in the green box.
The 'Fcn' block allows the user to directly enter the formula and view it by resizing the block to accommodate the length of the expression. However, if your Simulink library does not display the 'Fcn' block, an alternative option would be the 'Interpreted MATLAB Function' block, although this block is scheduled to be removed in a future release.

@Sam Chakさんへ
返答ありがとうございます。
知りたいのは赤枠の数式がどうやって作られたかです。
私が持っているデータで空気質量や点火時期を入力しても、エンジンベンチで想定した値とはだいぶ違うものになりました。
そこで、この数式に興味を持ち、係数を変更すればより使えるものになるのではないかと考えました。
なので、この数式の論文がどれかを知りたいのです。

According to the reference "Model Engine Timing Using Triggered Subsystems," the combustion engine model is based on a 1991 conference paper titled "A Nonlinear Engine Model for Drivetrain System Development" by Crossley and Cook. You may find an explanation there about how the torque equation was derived.
Unfortunately, I do not have access to the conference paper. I have provided the link to the abstract for your reference. If possible, you may wish to request assistance from your academic colleagues or friends who may have access to the full paper.
