Does non exhaust emission from electric vehicles more than conventional internal combustion engine vehicles?
5 answers
Non-exhaust emissions from electric vehicles (EVs) are a concern as they emit particulate matter (PM) similar to conventional internal combustion engine vehicles. Research indicates that EVs emit PM from brake wear, tire wear, road surface wear, and road dust resuspension, contributing to non-exhaust emissions like traditional vehicles. Additionally, studies highlight a positive correlation between vehicle weight and non-exhaust PM emissions, with heavier vehicles emitting more PM. While EVs aim to reduce tailpipe CO2 emissions, their initial manufacturing pollution can lead to increased lifetime CO2 emissions compared to internal combustion engine vehicles. Hybrid electric vehicles (HEVs) are positioned between EVs and ICEVs in terms of CO2 emissions, with HEVs optimized through dynamic programming showing potential for lower lifetime emissions without compromising performance.
How do various methods for enhancing power output differ in terms of safety considerations?
5 answers
Various methods for enhancing power output differ in terms of safety considerations. For instance, a power safety system involving MOSFETs and a body controller is designed to prevent reverse current flow. On the other hand, a steam reheat process in a thermal power cycle aims to increase power output without atmospheric emissions by utilizing oxyfuel combustion and carbon dioxide capture. Additionally, the use of a thyristor with a controller can enhance power output by manipulating current flow between the anode, gate, and cathode, ultimately providing an enhanced voltage to the cathode. In contrast, the load raising process in gas turbines involves replacing air-cooled components with steam-cooled components to withstand high temperatures, ensuring operational safety. Each method addresses power enhancement while considering specific safety aspects relevant to its application.
