👉 Engine fumes, primarily composed of carbon monoxide (CO), nitrogen oxides (NOx), hydrocarbons (HC), and particulate matter (PM), are byproducts of internal combustion processes. Carbon monoxide, a colorless and odorless gas, forms when fuel is incomplete burned, often due to rich fuel-air mixtures or faulty exhaust systems. Nitrogen oxides result from high-temperature reactions between nitrogen and oxygen in the air, contributing to smog and acid rain. Hydrocarbons, especially unburned or partially burned fuel, emit a range of compounds that can be toxic and harmful at high concentrations. Particulate matter, consisting of tiny solid or liquid particles, includes soot and other combustion byproducts, which can penetrate deep into the lungs and cause respiratory issues. These emissions not only pose health risks but also contribute to environmental degradation, making engine maintenance and emission control technologies crucial for reducing their impact.
