[PDF] Combustion in the Chemistry Classroom The Ideal Ratio

STOICHIOMETRY OF COMBUSTION

combustion of fuel results from the equation of stoichiometry of oxygen/fuel reaction Stoichiometric air means the minimum air in stoichiometric mixture The stoichiometric air/fuel ratio (AFR) can be calculated from the reaction equation (g/g) For gas AFR is usually determined in m3/m 3

Combustion in the Chemistry Classroom The Ideal Ratio

internal combustion engine and emissions 3 Students will engineer and examine the accuracy of a device to measure airflow 4 Students will account for the various factors that must be explored and assessed when trying to identify and develop a feasible biofuel for internal combustion engines Connections to Chemistry

Chapter 2 Thermodynamics of Combustion

Thermodynamics of Combustion 2 1 Properties of Mixtures The thermal properties of a pure substance are described by quantities including internal energy, u, enthalpy, h, specific heat, c p, etc Combustion systems consist of many different gases, so the thermodynamic properties of a mixture result from a
