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.

Empa and partners exploring DME as fuel with new heavy-duty test engine

Green Car Congress

In cooperation with a major European supplier, a new oil-lubricated common-rail pump had therefore been developed. An electrically driven compressor for precise exhaust gas recirculation is also used. Then we modify the timing and pressure of the injection, among other things, and look at exhaust emission values and fuel consumption.

FPT International introduces 8.7-liter CNG engine in China

Green Car Congress

To comply with Euro VI the Cursor 9 CNG does not need Exhaust Gas Recirculation (EGR) or Selective Catalytic Reduction (SCR), but relies on a simple three-way catalyst. Compared to the Cursor 9 diesel, the new engine has a Ni-Resist cast-iron exhaust manifold and water cooled wastegate turbocharger, increasing reliability.

liter diesel, prominently showing the closely attached exhaust aftertreatment system. For example, depending on the emission requirements, 3 different types of exhaust gas recirculation (EGR ) can be used: cooled high-pressure EGR without low-pressure EGR; cooled low-pressure EGR without high-pressure EGR; or. Oil and vacuum pump.

This means that the turbocharger and the exhaust manifold are now positioned at the rear, on the side of the firewall when viewed from behind. Furthermore, the new arrangement allows much improved air ducting with shorter distances and fewer diversions - both on the intake and exhaust side. Turbocharger.

ICCT life-cycle analysis finds no climate benefit in using LNG as marine fuel

Green Car Congress

The results of a new analysis by the International Council on Clean Transportation (ICCT) show that, when combined with a trend toward higher methane leakage and combustion slip, there is no climate benefit from using liquefied natural gas (LNG) as a marine fuel—regardless of the engine technology. First, it contains very little sulfur.
