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.

ABS grants Alfa Laval the marine industry’s first approval in principle (AIP) for firing boilers with methanol

Green Car Congress

Alfa Laval offers a range of oil-fired and oil and exhaust gas-fired boilers for ships. Top-fired and available in two different design pressures, the Aalborg OL is a vertical, two-drum cylindrical boiler. One of these is the use of an Alfa Laval Aalborg Micro economizer in conjunction with the OS-TCi.

Optimized heavy-duty CI engine fueled with DME delivers diesel performance, significantly reduces engine-out emissions

Green Car Congress

With the most recent design, an increase of the efficiency level of around 1–2 percent-points can be expected. The common rail pump was externally lubricated by engine oil so that it can handle the low fuel lubricity. Above around 6–7 bar bmep, the engine’s efficiency is above 40% and the maximum efficiency is slightly above 45%.
