Driving Conditions and Non-Exhaust Emissions
1. Speed
- Higher Speeds: Generally, higher speeds tend to increase non-exhaust emissions due to increased tire and brake wear.
- Lower Speeds: Slower speeds, such as in city driving, might reduce non-exhaust emissions because of less intense brake use.
2. Weight of the Vehicle
Electric vehicles are typically heavier than internal combustion engine vehicles (ICEVs), which can increase tire and brake wear under certain conditions. However, research suggests that despite their weight, EVs often produce less non-exhaust emissions than ICEVs in overall comparisons.
3. Aggressive Driving
- High Acceleration: Aggressive driving styles that involve frequent high acceleration can increase non-exhaust emissions due to increased brake and tire wear.
4. Road Conditions
- Rough Roads: Driving on rough surfaces can increase tire wear, potentially leading to higher non-exhaust emissions.
- Smooth Roads: Conversely, driving on smooth roads might reduce tire wear.
5. Brake Use
- Frequent Braking: Frequent braking, common in city driving, increases non-exhaust emissions from brake wear.
- Regenerative Braking: Many EVs use regenerative braking, which can reduce brake wear compared to traditional braking used in ICEVs.
Research Findings
- Recent research by the Virginia Tech Transportation Institute has shown that electric vehicles generally produce fewer non-exhaust emissions compared to gasoline-powered vehicles under certain conditions.
- The study highlights the importance of vehicle weight and speed in calculating non-exhaust emissions, indicating that while EVs are heavier, they can still offer environmental advantages in terms of reduced emissions.
Overall, while electric vehicles do produce non-exhaust emissions, they tend to generate fewer of these emissions than ICEVs across various driving conditions.
