The most significant compositional difference between the exhaust PM from combustion of the 2 fuels was the ratio of polar to non-polar species: 46% assigned polar for B0 vs 68% polar compounds for the B20 fuel. We are unaware of previous studies reporting this type of comparison of the exhaust PM.

Toyota introduces 2012 Prius Plug-in Hybrid

Green Car Congress

The 2012 Prius Plug-in Hybrid retains the Hybrid Synergy Drive of the standard Prius model and will seamlessly switch into hybrid operation at a pre-determined state of battery charge. With lower exhaust heat, heat efficiency was enhanced, and consequently, fuel efficiency was enhanced as well. Entune with plug-in hybrid applications.

It covers ten Northeastern and Mid-Atlantic states (Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Rhode Island, and Vermont). To be credible, as noted above, an offset should equate to an emission reduction from a direct emission source, such as a smokestack or exhaust pipe.
