California ARB approves ACC II rule; 100% of LDVs to be PHEVS, ZEV by 2035; LEV IV emissions requirements

Green Car Congress

The main objective of ACC II is to maximize criteria emission reductions from internal combustion engine vehicles (ICEVs), while accelerating the transition to deployment of ZEVs through both increased stringency of requirements and associated actions to support wide-scale ZEV adoption and use. grams per mile down to 0.01 grams per mile.

SAE High Octane Fuels Symposium: Is a new high-octane fuel a pragmatic pathway for higher engine efficiency in the US? (part 2)

Green Car Congress

As highlighted at the 2013 SAE International High Octane Fuels Symposium (HOF) last week, high octane fuels—combined with optimized engines—are viable enablers to higher efficiency operation. Gasoline or E10 BOB would be premium-grade fuel for total coverage of legacy fleet. Earlier post.). with ethanol content.

Perspective: US Needs to Transition to Hydrous Ethanol as the Primary Renewable Transportation Fuel

Green Car Congress

In 1975, General Ernesto Geisel, then-president of Brazil, ordered the country’s gasoline supply mixed with 10% ethanol. The level was raised to 25% over the next five years, which was intended to maintain a constant Brazilian gasoline supply for an ever-increasing demand. These were arguably the first flex-fuel vehicles.

Perspective: Europeans in the lead with range extenders for hybrid vehicles; 2nd vs. 3rd generation

Green Car Congress

By contrast, half the electric vehicle market value lies in larger road vehicles, notably cars, and here the legal restrictions are weaker or non-existent and range anxiety compels most people to buy hybrids if they go electric at all. These second generation engines retain piston-driven, internal combustion technology.

New Study Finds Flaw in Carbon Accounting for Bioenergy, Another Contends That Indirect Land Use Change Emissions for Biofuels Will Be Up To Twice Direct Land Use Change Emissions

Green Car Congress

Thirteen scientists and land use experts conclude in a new paper that an important but fixable error in legal accounting rules used to measure compliance with carbon limits for bioenergy could undermine efforts to reduce greenhouse gas emissions by encouraging deforestation. Their paper is published in the 23 Oct. Earlier post.).
