METHOD FOR ANALYZING OXIDATION IN AN INTERNAL COMBUSTION ENGINE

摘要

A process for analyzing incomplete fuel oxidation in an internal combustion engine is provided. The process includes simulating a cylinder with a cylinder wall and a piston within the cylinder for the internal combustion engine. Based on the simulation of the internal combustion engine operation, a pressure and a temperature are determined at a predetermined location within the cylinder for at least one piston crank angle. In addition, combustion of fuel at the predetermined location within the cylinder is simulated and a determination of combustion products is provided. In this manner, simulation of incomplete oxidants produced during operation of the internal combustion engine is afforded and can be used for the design of engine components such as cylinder walls, piston heads, piston rings, valves, spark plugs, and the like.

1. A process for analyzing incomplete fuel oxidation in an internal combustion engine, the process comprising:
providing a computer environment operable to execute algorithms, calculations and simulations; simulating operation of an internal combustion engine, the internal combustion engine having a cylinder with a cylinder wall and a piston within the cylinder; determining a pressure and a temperature at a predetermined location within the cylinder for at least one predetermined crank angle for the piston within the cylinder, the predetermined location being in front of a simulated flame-front in the cylinder proximate to the cylinder wall; modeling a fuel; simulating combustion of the fuel at the determined pressure, temperature and predetermined location within the cylinder; and determining combustion products of the simulated combusted fuel at the predetermined location, for the purpose of simulating incomplete oxidants produced during operation of the internal combustion engine.
