Why get pzev

Vehicle emissions are worst in cold start conditions. Subaru addresses this problem by altering the programming in the Engine Control Module to delay ignition timing, making the exhaust gasses hotter, which helps the catalytic converter heat up sooner, reducing emissions.

Carbon Air Intake Traps: After turning off the engine, fuel vapors can stay in the combustion chamber and leak out, causing emissions. PZEVs have carbon air intake filters in the engine to prevent these vapors. This filtering system has a charcoal canister designed to absorb these emissions efficiently.

Carbon Canister Scrubbers: Fuel vapors can also leak out and evaporate from the fuel cap, especially when outside temperature changes occur. PZEVs have carbon canister scrubbers installed in the fuel line that runs from the fuel line to the gas tank to prevent these emissions. These catalytic converters are designed to get vehicles to speed quickly while eliminating nitric oxide and nitrogen dioxide.

Close-coupled catalytic converters are lined with precious metals like platinum, palladium, and rhodium. When nitric oxide and nitrogen dioxide pass through, the catalytic converters change them into less harmful gases.

Programming changes in the ECM delays ignition timing, which makes exhaust warmer. As a result, the converter and other fuel system parts warm up more quickly, which can lower emissions. What's the benefit of getting a car with a PZEV badge? Cars that have a PZEV badge can help decrease your carbon footprint significantly.
