PwC: Global Carbon Budget For 2000-2050 Could Be Exhausted By 2034

Green Car Congress

Global accounting firm PricewaterhouseCoopers has analyzed carbon emissions from 2000 to 2008 and concluded that the world’s “carbon emissions budget”, or ability to emit carbon dioxide while still maintaining a “fair chance” of limiting average global temperatures to no more than 2 ÂșC (3.6 Click to enlarge.

SwRI develops D-EGR demonstrator highlighting fuel-efficient, cost-effective engine; 10% and above fuel economy improvements

Green Car Congress

D-EGR is an engine and control concept that combines fuel reforming to produce hydrogen with high levels of exhaust gas recirculation (EGR) to achieve very high levels of thermal efficiency. liter engine running as a full D-EGR engine from idle to full load, delivering more than 42% brake thermal efficiency with ultra-low exhaust emissions.

Chevrolet introduces second-generation Duramax 4-cylinder diesels; global engine

Green Car Congress

Better efficiency also means better reliability, economy as well as lower emission levels. The new Duramax engine uses an electric EGR valve for greater precision and a larger EGR cooler to further reduce recirculated exhaust gas temperature. The second generation engine offers better fuel economy, performance and lower emissions.

U Toronto study measures GDI emissions in urban near-road environment

Green Car Congress

One response by automakers to increasingly stringent fuel economy requirements is the use of GDI engines, which offer up to a 25% improvement in fuel economy compared to port fuel injection (PFI) engines. Hence, GDI PM mass loadings and chemical composition may vary depending on the measurement environment or exhaust conditioning.
