INTERNAL COMBUSTION ENGINE MODELING
Over the course of the quarter, the project for my internal combustion engines class was to code a 0-dimensional, crank-angle-resolved simulation of a single piston in a spark-ignition engine. We used a plug-in called Cantera to solve the thermodynamics and chemical kinetics.
Features
The code was able to simulate the following:
- Variable air/fuel ratio
- Mass flow rate through valves
- Variable valve lift (VVL)
- Variable valve timing (VVT)
- Gradual combustion using the Wiebe function and chemical kinetics
- Intake/exhaust manifold back-flow
- Steady-state convergence between cycles
- Exhaust gas concentrations
Results
The results were outputted in the form of plots
