Wärtsilä and partners developing emissions-free barge concept

Green Car Congress

The technology group Wärtsilä has joined a consortium of key partners to form Zero Emission Services B.V. The concept is supported by the Dutch Ministry of Infrastructure and Water Management. Within the Netherlands transport sector, inland navigation accounts for 5% of carbon dioxide emissions.

DNV and PSE develop concept for on-ship chemical CO2 capture; capable of reducing ship CO2 emissions by up to 65%

Green Car Congress

(PSE), a global provider of advanced process modeling technology, have developed a concept design for shipboard chemical CO 2 capture. The results from the Maritime CCS (carbon capture and storage) research and development project show that the concept is technically feasible and capable of reducing ship CO 2 emissions by up to 65%.

New split-cycle concept to control diesel HCCI combustion

Green Car Congress

A team from Universita degli Studi di Pisa (Italy) and Rolf Reitz at the University of Wisconsin-Madison are proposing a novel combustion concept—Homogenous Charge Progressive Combustion (HCPC)—based on a split-cycle principle to control HCCI combustion in diesel-fueled engines. Tamagna, D., Gentili, R. ICEF2007-1743 (2007).

Ricardo and Doosan DL06 diesel with TVCS achieves Tier 4f emissions without need for DPF

Green Car Congress

The new US Tier 4 Final (Tier 4f) version of the DL06 includes an ultra-low particulate combustion system featuring the Ricardo Twin Vortex Combustion System (TVCS) ( earlier post ); the engine achieves compliance with Tier 4 Final particulate emissions levels without requiring a DPF—thereby providing a cost-effective solution.

ArcelorMittal introduces new set of S-in motion solutions for BEVs

Green Car Congress

For example, the S-in motion Battery Pack concept includes design options with a tray, without a tray, and different material strategies are considered. And if we reduce the mass of materials, we directly reduce the emissions that are caused by the production of these materials. New emissions legislation targets full vehicle lifecycle.

SwRI D-EGR gasoline demo vehicle delivers diesel efficiency at lower cost; potential for LEV III/Tier 3 emissions

Green Car Congress

D-EGR is a SwRI-developed gasoline engine concept that uses in-cylinder fuel reforming to produce CO and H 2 (with Research Octane Numbers of 106 and 130, respectively) and high levels of recirculated gas (EGR) to achieve very high levels of thermal efficiency. D-EGR brake specific fuel consumption (BSFC) at 2000 rpm 2 bar BMEP dropped 14.3%
