A two-zone model is simulated with MATLAB, and you can find Volume, Area, Velocity, Burn Fraction, Unburned/Burned Area/Mass/Temperature/Volume, Pressure, and Work here.

In Sec.1 some initial values such as Compression Ratio, density, etc are configured.

In Sec.2 Volume and Area are calculated.

Fig.1 –Each Cylinder Volume

Fig.2 – The Cylinder Area

In Sec.3 The velocity is calculated.

Fig.3 – The Velocity

In Sec.4 The burn Fraction is calculated.

Fig.4 – The Burn Fraction

In Sec.5 The main calculation is done.

Fig.5 – The Unburned/Burned Area

Fig.6 – The Unburned/Burned Mass

Fig.7 – The Unburned/Burned Temperature

Fig.8 – The Unburned/Burned Volume

Fig.9 – The Motoring Pressure

Fig.10 – The Pressure

Fig.11 – The Work

In Sec.6 & 7 figures are configured.
