Study Notes
Gasoline Composition and Combustion
- The primary component of gasoline is hydrocarbons, primarily consisting of alkanes, cycloalkanes, and aromatic hydrocarbons.
- During combustion, nitrogen combines with oxygen to form nitrogen oxides (NOx), which are undesirable byproducts contributing to air pollution.
Air/Fuel Ratio
- The ideal air/fuel ratio for optimal emissions, fuel economy, and engine performance is approximately 14.7:1 (stoichiometric), meaning 14.7 parts air to 1 part fuel.
Byproducts of Hydrocarbon Combustion
- The two primary byproducts of hydrocarbon combustion in fuel are carbon dioxide (CO2) and water vapor (H2O).
- Additionally, unburned hydrocarbons and carbon monoxide (CO) can also be produced if combustion is incomplete.
Emissions Control Knowledge
- A thorough understanding of the emissions control system is essential for diagnosing and repairing it, which includes knowledge of fundamental engine operation, combustion processes, and emission regulations.
