High-Emitting vehicles pilot:
There are many different ways to reduce air pollution from passenger vehicles. In order to efficiently address emissions, Environmental Initiative and partner garages identified three types of equipment repairs: catalytic converters, Evaporative Emission Control (EVAP) systems, and oxygen sensors.
Catalytic converters are devices that convert harmful gases and pollutants normally found in exhaust gas into harmless compounds by triggering chemical reactions that break down carbon monoxide and the precursors to smog. They can be installed ahead of the existing muffler or as a unit combined with a muffler.
evaporative emission control (evap) systems
A functioning Evaporative Emission Control (EVAP) system prevents fuel vapors from exiting the fuel tank and other fuel system components, blocking harmful volatile organic compounds, or VOC’s from entering the air. The major components of an EVAP system include the fuel tank, gas cap, EVAP canister, and liquid-vapor separator.
Oxygen sensors are devices that measure the oxygen to fuel ratio, controlling how much fuel is injected into the engine. Oxygen sensors are mounted inside the exhaust system. From there, they track how much oxygen is in the exhaust being emitted. Repairing the oxygen sensors can improve fuel efficiency, minimize exhaust emissions, and extend the life of the catalytic converter.
