Study finds engines emit exhaust nanoparticles even when not fueled during engine braking

Green Car Congress

Exhaust particle size distributions measured by ELPI (color map) and particle concentration measured by CPC (white line) during individual engine braking conditions (speed change from 32 km/h to 0 km/h). The exhaust sample was taken from the exhaust manifold. The exhaust sample was taken from the exhaust manifold.

NSF and DOE form Partnership on Advanced Combustion Engines; goal 25-40% better LDV fuel economy and 55% BTE in heavy-duty engines; $12M in awards for FY 2012-2014

Green Car Congress

The high-level performance goals of the Partnership are a 25-40% improvement in fuel economy in a light-duty vehicle (LDV) and achieving 55% brake thermal efficiency (BTE) in heavy-duty engine systems. bio-derived) fuels have the potential to dramatically increase fuel economy. The potential is significant.

Daimler Trucks NA SuperTruck achieves 115% freight efficiency improvement over 2009 baseline; 50.2% engine BTE

Green Car Congress

The Freightliner SuperTruck features a low-back-pressure, next-generation aftertreatment system that efficiently removes NO x from the exhaust stream. The aftertreatment system features additional insulation to retain maximum heat energy in the exhaust. This reduces friction, and increases efficiency and fuel economy.

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

Green Car Congress

These distilleries made 192-proof alcohol for human consumption, lantern fuel and transportation fuel. The distilleries were referred to as “stills” and the alcohol became known during the Prohibition period as “moonshine.” During the early 1900s, a distillery was a standard piece of farm equipment.

Promising Delphi 1st-gen Gasoline Direct Injection Compression Ignition engine meeting ultra fuel efficient program targets

Green Car Congress

In 2010, The US Department of Energy (DOE) selected Delphi, along with partners Hyundai America Technical Center, Inc (HATCI); Wisconsin Engine Research Consultants (WERC); and the University of Wisconsin-Madison (UW) for a $7.48-million million grant to develop and to demonstrate a new ultra fuel efficient vehicle (UFEV) vehicle concept.

SAE REX: PHEVs and REEVs could open door for advanced combustion regime engines

Green Car Congress

High efficiency engines with low-carbon fuels clearly is a major, major pathway. Berube went on to reference the importance of DOE’s major new Co-Optima initiative ( earlier post ), an effort to co-optimize new fuels and light-, medium- and heavy-duty engines which together could achieve very significant performance improvements.
