New Emissions Analytics study suggests pollution from tire wear now 1,850 times worse than exhaust emissions

Green Car Congress

In early 2020, UK-based independent testing firm Emissions Analytics published a study claiming that tire particulate wear emissions were 1,000 times worse than exhaust emissions ( earlier post ). As a result, distance-specific mass and number emissions can be derived, which can then be compared to equivalent tire metrics.

Motiv Engines introduces 2nd-generation split-cycle concept; MkII Clarke-Brayton heavy-duty engine being designed for LNG

Green Car Congress

The thermodynamics of the engine are virtually identical to the company’s previous CCI (Compact Compression Ignition) design, as described in a 2013 SAE paper, but are implemented in a much more conventional way. It expands all the way to ambient pressure before the exhaust stroke. All valves are actuated by overhead cams.

Volkswagen 2.0 TDI diesel for Euro 6d; SCR twin-dosing

Green Car Congress

With SCR twin dosing technology in the exhaust gas system, the diesel unit now undercuts the Euro 6d emission standard limits while also running quietly and smoothly, according to the company. The four-cylinder TDI engine with the internal designation EA 288 made its debut in 2012. As previously, the 2.0

Volkswagen continues to optimize its EA888 workhorse engine; fourth evolution in 2022 Golf GTI and R

Green Car Congress

In 2022, the fourth evolution of the EA888 pushes state-of-the-art turbocharged engine design further still; it is one of the most advanced Volkswagen engines ever built. Known internally and to Volkswagen enthusiasts as the “Evo4,” its two most difficult roles might be under the hood of the 2022 Golf GTI and R. 1 for the GTI.

EPFL team develops on-board system to capture CO2 from trucks; reducing emissions by 90%

Green Car Congress

The EPFL system captures CO 2 directly in the trucks’ exhaust system and liquefies it in a box on the vehicle’s roof. First, the vehicle’s flue gases in the exhaust pipe are cooled down and the water is separated from the gases. Researchers at EPFL have patented a new concept that could cut trucks’ CO 2 emissions by almost 90%.
