Method for analyzing oxidation in an internal combustion engine

A process for analyzing incomplete fuel oxidation in an internal combustion engine, the process comprising:

• providing a computer having an ECU, memory, a database and a software module, the computer operable to execute algorithms, calculations and simulations;
• simulating operation of an internal combustion engine using the computer, the internal combustion engine having a cylinder with a cylinder wall and a piston within the cylinder;
• determining pressures and temperatures within the cylinder for at least one predetermined crank angle;
• reading a temperature and a pressure from the determined pressures and temperatures for a predetermined location, the predetermined location being in front of a simulated flame-front in the cylinder proximate the cylinder wall;
• modeling a fuel;
• simulating combustion of the modeled fuel at the predetermined location within the cylinder;
• and
• determining combustion products of the simulated combusted fuel at the predetermined location, for the purpose of determining if incomplete oxidants produced form operation of the internal combustion engine.
