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.

Improved liquid hydrogen-powered Corolla and GR86 (carbon-neutral fuel) to participate in Super Taikyu at Autopolis

Green Car Congress

Lubricating oil is usually used in pumps to reduce stress through less friction in the pump; however, lubricating oil cannot be used in liquid hydrogen pumps as it contaminates the hydrogen. In addition, pump stress has been reduced by optimizing fuel pressure, leading to a weight reduction for the pump drive motor battery.
