Rolls-Royce developing methanol-fueled mtu engines for shipping

Green Car Congress

The combustion of methanol in a pure methanol engine can be climate-neutral with significantly reduced nitrogen oxide emissions, thus eliminating the need for complex SCR exhaust gas aftertreatment. Unlike ammonia, methanol is not highly toxic and is environmentally safe.

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

Green Car Congress

Southwest Research Institute (SwRI) announced preliminary test results of its Dedicated-Exhaust Gas Recirculation (D-EGR) demonstration vehicle ( earlier post ) at the SAE 2014 World Congress in Detroit. The D-EGR demonstrator is a converted 2012 Buick Regal with a 2.0-liter Hydrogen-enriched exhaust is routed to the intake.

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 four campaigns over the year-long study, the team from the University of Toronto measured emissions 15 meters from the roadway, then converted the measurements to fuel-based emission factors (EFs). Hence, GDI PM mass loadings and chemical composition may vary depending on the measurement environment or exhaust conditioning.

2015 VW Jetta TDI: a more refined, powerful and efficient diesel within a nicely redesigned model line

Green Car Congress

The aluminum-alloy cross-flow cylinder head has a novel placement of intake and exhaust valves; the intake and exhaust ports for each cylinder are positioned one behind the other in the direction of flow. In other words, there is not a separate intake or exhaust camshaft. Top: Valve layout. We can now adjust about 50 ?
