Maryland commits to ban on gas vehicle sales

Teslarati

Maryland aligned with the California Air Resource Board (CARB) vehicle standards in 2011 and is one of seventeen states in the U.S. Car exhaust is the largest source of greenhouse gas in the State of Maryland. .” Maryland laws already exist that require the State to match California’s vehicle emissions programs.

Small-displacement two-stroke H2 engine could address performance and emissions cost-effectively for recreational market; potential for Asian motor vehicle fleet

Green Car Congress

Oh presented a paper on the work, which was the result of two years of research activity in conjunction with Bombardier Recreational Projects, at the ASME 2012 Internal Combustion Engine Division Fall Technical Conference. For one, the [California Air Resources Board] CARB-established limit of HC+NO x emissions in the 7.4

Progress on ATLAS: Cummins’ Tier 2 Bin 2 light duty diesel project

Green Car Congress

Michael Ruth, Principal Investigator for the project at Cummins, provided an update on progress at the recent 2011 DEER conference. The engine will leverage low-pressure EGR to reduce pumping work, and feature a fabricated exhaust manifold (rather than using cast iron). The DOC/DPF aftertreatment is assembled onto engine.

Use of Supercritical Diesel Fuel for Improved Efficiency and Reduced Emissions

Green Car Congress

Heat required to bring the fuel to SC states is recovered from the exhaust gas of the engine. George Anitescu from Syracuse presented the work in a poster at the DEER 2009 conference in Dearbon, Michigan. To attenuate that risk, the researchers use a diluent such as CO 2 , H 2 O or exhaust gas. At SC conditions, however (T?450

Study suggests that decarbonizing US transport sector by converting waste CO2 to fuels would require economical air-capture of CO2

Green Car Congress

Kreutz presented the paper at the 10 th International Conference on Greenhouse Gas Control Technologies ( GHGT-10 ) earlier this fall in The Netherlands. Direct capture of CO 2 from air, or from an exhaust stream vented to the atmosphere, represents negative emissions. Kreutz used what he called a bifurcated climate regime—i.e.,

Pinnacle’s opposed-piston scooter engine can meet NOx target with lean operation and ignition delay; little fuel economy hit

Green Car Congress

Separate from the combustion stability and NO x testing, Pinnacle ran a 400-hour durability test on its engine and essentially found no change over time in power, torque, oil consumption or mechanical components (e.g., When the entire vehicle costs around $700, that’s a significant difference. valve and seal), Cleeves said.

University of Wisconsin Researchers Investigating Dual-Fuel (Gasoline and Diesel) Partially Premixed Combustion for High-Efficiency, Ultra-Low Emission Combustion; 53% Thermal Efficiency

Green Car Congress

Kalghatgi and his group explored both the use of low-cetane fuels and exhaust gas recirculation (SAE 2007-01-0006). million barrels of oil per day in transportation. Other researchers have looked at high EGR rates (Akihama et al. SAE 2001-01-0655), and optimizing fuel reactivity (Bessonette et al., SAE 2007-01-0191). Rolf Reitz.
