Definition of Vehicle Exhaust
Vehicle exhaust refers to the gases and particulate matter that are expelled from an internal combustion engine as a result of burning fuel. It is a byproduct of the combustion process in vehicles, including cars, trucks, motorcycles, and other motorized transport. Understanding the components and characteristics of vehicle exhaust is crucial for using the term accurately.
Components of Vehicle Exhaust
Vehicle exhaust is composed of various substances, some of which are harmful pollutants. The primary components include:
- Carbon Dioxide (CO2): A greenhouse gas that contributes to climate change.
- Water Vapor (H2O): A natural byproduct of combustion.
- Nitrogen (N2): The most abundant gas in the atmosphere, also present in exhaust.
- Carbon Monoxide (CO): A toxic gas that can cause health problems.
- Nitrogen Oxides (NOx): Pollutants that contribute to smog and acid rain.
- Particulate Matter (PM): Tiny particles that can cause respiratory issues.
- Hydrocarbons (HC): Unburned or partially burned fuel that can contribute to smog.
- Sulfur Dioxide (SO2): A pollutant that can cause respiratory problems and acid rain.
Classification and Function
Vehicle exhaust is classified as an emission, meaning it is a substance released into the environment. Its function is as a waste product of the combustion process in internal combustion engines. From an environmental perspective, it is often considered a pollutant due to its harmful effects on air quality and human health. From an engineering perspective, managing and reducing vehicle exhaust is a key goal in developing cleaner and more efficient vehicles.
Contexts of Use
The term “vehicle exhaust” is used in a variety of contexts, including:
- Environmental Science: Discussing the impact of vehicle emissions on air quality and climate change.

Based on Fuel Type
The composition of vehicle exhaust varies depending on the type of fuel used:
- Gasoline Exhaust: Emissions from vehicles using gasoline.
- Diesel Exhaust: Emissions from vehicles using diesel fuel, often containing more particulate matter.
- Electric Vehicle Exhaust: Technically, electric vehicles produce zero *tailpipe* emissions. However, the electricity used to power them may be generated from sources that produce emissions. This is often referred to as “well-to-wheel” emissions.
- Hybrid Vehicle Exhaust: Emissions from hybrid vehicles, which combine gasoline and electric power.
- Alternative Fuel Exhaust: Emissions from vehicles using alternative fuels such as ethanol, biodiesel, or natural gas.
Based on Pollutants
Vehicle exhaust can also be categorized by the specific pollutants it contains:
