What is subaru pzev

For many years now, all Subaru vehicles are built in manufacturing facilities that achieve zero landfill status. With Subaru PZEV vehicles, the remarkable reduction of smog-forming emissions is achieved through modifications in four key areas:.

A larger and finer mesh of catalyst-lined passageways within a Subaru PZEV catalytic converter greatly contributes to its ability to reduce emissions. Along the entire length of the mesh are precious metals catalysts whose role is to change the molecular structure of the offensive emissions that try to pass through. In fact, the contact area is almost twice that of a traditional catalytic converter, producing a much more effective conversion of pollutants. The fuel injectors on Subaru PZEV vehicles close tighter than conventional injectors to prevent evaporative emissions from fuel leakage into the intake manifold.

To prevent this, Subaru PZEVs are equipped with a charcoal canister in the air intake that absorbs these evaporative hydrocarbon emissions.

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.

To prevent this, Subaru PZEVs are equipped with a charcoal canister in the air intake that absorbs these evaporative hydrocarbon emissions.

The dual-filtration air-intake system has been updated in the PZEV to remove the gap in the dual-filtration air-intake system that can allow for emissions to escape when the engine is off. By adjusting the programming in the Engine Control Module they were able to delay ignition timing, which makes the exhaust gas warmer, which helps everything else warm up faster including the converter , which helps reduce emissions.
