ARB researchers evaluate in-use heavy-duty NOx aftertreatment systems, find elevated levels during certain lower-temperature operations

Green Car Congress

One of the trucks was equipped with exhaust gas recirculation (EGR); three were equipped with EGR and a selective catalytic reduction (SCR) device. EGRs were primarily introduced for on-road heavy-duty diesel engines over a decade ago to meet the tighter MY 2004 NO x standard (2 g/bhp-hr). deionized water); poor DEF quality; and.

BMW Outlines Intelligent Heat Management Applications for Reducing Fuel Consumption and CO2; New Thermoelectric Generator Unit Integrated with EGR

Green Car Congress

The remaining two-thirds are lost as waste heat going into the environment through the car’s exhaust emissions and through the radiator. Making some of that waste heat energy available through intelligent heat management offers significant potential for reducing fuel consumption and CO 2 emissions, BMW said.

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

Green Car Congress

Under the Proalcool Program, sugar companies were ordered to increase production and the state-run oil company, Petrobras, was required to make álcool (ethanol) available at its fuel stations. The first such vehicles were introduced by Volkswagen in 2003, and by 2004, they accounted for more than 17% of the Brazilian auto market.

Unfavourable mixtures of liquid fuels, water and air lead to degradation by local hot spots in the sensitive catalysts and to formation of unwanted by-products in the reformer. This allows SAFCell stacks to run more easily on commercially available gas fuels (e.g., The reformer converts hydrocarbons into hydrogen, CO 2 and heat.

Ford Unveils Next-Generation Global Focus at NAIAS; Features New 2.0L DI Engine with Powershift Dual-Clutch Transmission for NA Market

Green Car Congress

US small car sales—combined B- and C-segments—grew from about 14% of the market in 2004 to more than 21% now. Ti-VCT applies variable cam timing to both the intake and exhaust camshafts of its DOHC design, using electronic solenoid valves to direct high-pressure oil to control vanes in each of the camshaft sprocket housings.

Toyota Previews Generation III 2010 Prius Hybrid

Green Car Congress

With the replacement of the engine’s belt-driven water pump, all engine coolant pumps are now electrically operated, reducing mechanical losses and providing engine coolant flow rate control independent of engine RPM at all times. An exhaust gas recirculation (EGR) system has also been added. The 2010 Prius features a new 1.8-liter

Ricardo investigating potential for its split-cycle engine in large engine market

Green Car Congress

Key changes to implement the integrated cycle are isothermal compression and heat addition from the exhaust gas to the charge air after the end of compression. To transfer exhaust gas heat at the end of compression requires the use of a “split cycle” in which the standard four-stroke sequence is split into two separate elements.
