EPA says methane emissions from natural gas production have dropped 36% from 2007-2011

Green Car Congress

In its recently released Inventory of US Greenhouse Gas Emissions and Sinks: 1990 – 2011 ( earlier post ), the US Environmental Protection Agency (EPA) reported that methane (CH 4 ) emissions from the field production of natural gas have declined by 36% from 2007 to 2011 (from 83.1 Tg or million metric tons CO 2 equivalent.)

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.

VW introducing 1.8L EA888 Gen 3 engine in 2014 Jetta, Passat and Beetle; driving impressions

Green Car Congress

Key advances for Gen 3 are in weight reduction, friction reduction, and the internal exhaust cooling system. Volkswagen first launched the EA888 engine generation in spring 2007 (Gen 1). Like its predecessor, the engine has a cast-iron cylinder block and an aluminum-alloy cylinder head which now has the exhaust headers cast integrally.

US charges Audi manager with conspiracy to cheat US emissions tests; sacrificing NOx control for a sound system

Green Car Congress

According to CW1 and the documentation, Pamio and his co-conspirators realized they could not calibrate a diesel engine that would meet the stricter NO x emissions standards that would become effective in 2007 while staying within the design constraints imposed by other departments at the company.

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. EGR reduces NO x formation by introducing cooled exhaust gases into the combustion chamber. EGR reduces NO x formation by introducing cooled exhaust gases into the combustion chamber.

Ports of Los Angeles and Long Beach to test new seawater scrubber device to cut vessel emissions

Green Car Congress

It provides for silencing of the exhaust noise. features advanced emission control technology in which seawater is used to scrub, or filter, contaminants from a ship’s auxiliary engines and boiler before exiting the exhaust stack of a ship. provided more than $5 million in project funding since the program began in 2007.
