Limited exhaust components for different types of vehicles

Factors affecting vehicle emissions:

• Engine size and technology: Larger engines generally produce more emissions than smaller engines, but this can vary depending on the specific engine technology. For example, a modern, fuel-efficient 4-cylinder engine may produce fewer emissions than a larger, older V6 engine.

• Transmission type: Automatic transmissions typically produce slightly more emissions than manual transmissions, as they require more energy to operate.

• Driving conditions: Emissions can vary significantly depending on driving conditions, such as stop-and-go traffic, highway driving, and weather conditions.

• Emission control systems: Different emission control systems can have a significant impact on emissions levels. Some common emission control systems include catalytic converters, particulate filters, and exhaust gas recirculation (EGR).

• Fuel type: The type of fuel used can also affect emissions. For example, gasoline-powered vehicles typically produce more greenhouse gas emissions than diesel-powered vehicles, while diesel-powered vehicles typically produce more nitrogen oxide (NOx) emissions.
