EU investing >€3M in research into ultra-efficient aero engines; ULTIMATE project

Green Car Congress

Europe’s Strategic Research and Innovation Agenda (SRIA 2050) outlines a 75% reduction in aviation CO 2 emissions to year 2050 relative to a year 2000 reference. The EU is targeting a 75% reduction in carbon dioxide emissions per passenger kilometer between the years 2000 and 2050. Core exhaust loss. Bypass flow loss.

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

Green Car Congress

In comparison, average PN EFs from a PFI vehicle exhibited less spatial variability, with mean PN EFs 15 m from the roadway 17% lower than those measured 3 m from the roadway. Hence, GDI PM mass loadings and chemical composition may vary depending on the measurement environment or exhaust conditioning. —Zimmerman et al.

Mercedes-Benz powering ahead with €3B strategic engine initiative; increasing electrification, 48V; diesel and gasoline; cylinder deactivation

Green Car Congress

The new six-cylinder in-line engine comes with an intelligent form of turbocharging: assisted by the ISG at start-off, the electric auxiliary compressor (eZV) guarantees immediate high torque when driving off and accelerating, bridging the time before the large exhaust turbocharger cuts in.

Audi banking on Gen 2 3.0L TDI diesel for US sales; calls for a “fair shot” for diesel

Green Car Congress

During his presentation at the TDI Efficiency Rally, UMTRI researcher Bruce Belzowski first presented a summary of his analysis of the total cost of ownership of diesels with a comparison to that of their gas vehicle counterparts. Changes in the exhaust manifolds and turbo from Gen 1 to Gen 2. Earlier post.). lbs (4 kg). Q5 hybrid **.

Study suggests high-mileage light-duty fleets contribute higher emissions and emissions share than expected

Green Car Congress

The researchers used the West LA data as a baseline for comparison with the high-mileage fleet measurements. They used remote vehicle exhaust sensors to collect emissions measurements, and recorded a video image of the license plate of each vehicle. of the registered vehicles (2000/325000). In their study, Bishop et al.

ORNL Research Project Seeks to Boost Combustion Engine Efficiency To 50-60% By Reducing Combustion Irreversibility; RAPTR

Green Car Congress

Regenerative Air Preheating (RAP) uses a counterflow heat exchange between exhaust and inlet air via solid media (e.g., Thermo-chemical recuperation uses recovered exhaust heat to drives endothermic reforming reactions. as in Stirling engines) to minimize the temperature gradient.

GISS study finds applying stricter non-CO2 vehicle emission standards worldwide would yield climate benefits in addition to major health and agricultural benefits

Green Car Congress

Impacts of worldwide vehicle emissions in 2030 compared with 2000. Shindell and colleagues used a comprehensive computer model and climate simulator—one of the first capable of accounting for the role of aerosols—that shows vehicle exhaust exacts an enormous toll in all countries and especially in the developing world.
