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.

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.

New Ford Escape launching with two new EcoBoost engines with standard Auto Start-Stop

Green Car Congress

The start-stop technology senses when the vehicle is sitting idle and shuts off the engine to conserve fuel, resulting in a 4 percent to 6 percent improvement in fuel economy in stop-and-go traffic. A six-speed automatic transmission is standard across the line, with new paddle-shift technology available for Escape SE and Titanium.

Union Pacific Railroad investing $20M to test emissions-reducing locomotive technology in California; moving toward Tier 4 compliance with combination of EGR, DOC and DPF

Green Car Congress

One locomotive in this series of 25 will be based in Roseville to test the combined use of exhaust gas recirculation (EGR), diesel oxidation catalyst (DOC), and diesel particulate filtering (DPF). The proposed standards would also yield sizeable reductions in emissions of HC, CO, and other air toxics.
