Emissions Analytics finds pollution from tire wear can be 1,000x worse than exhaust emissions

Green Car Congress

Pollution from tire wear can be 1,000 times worse than a car’s exhaust emissions, Emissions Analytics has found. Emissions Analytics is an independent global testing and data specialist for the scientific measurement of real-world emissions and fuel efficiency for passenger and commercial vehicles and non-road mobile machinery.

Exhaust and aftertreatment on the Achates ULNOx heavy-duty opposed-piston diesel

Green Car Congress

However, during development, the project team was able to exceed the program expectation for engine-out NO x and exhaust temperature control in the catalyst warm-up mode and concluded that the tailpipe NO x targets can be met without the close coupled light-off SCR. The OP engine operates at nearly ideal temperature range.

Bosch increases commercial vehicle diesel injection pressure to 2,500 bar

Green Car Congress

As it outlined in 2010, Bosch has increased the maximum injection pressure of its CRSN3-25 injection system for medium- and heavy-duty commercial vehicles to 2,500 bar. This increases flexibility in terms of engine design, promotes lower exhaust and fuel consumption levels, and results in even quieter operation.

Study links deterioration of concrete and asphalt to trace quantities of organic matter; diesel exhaust, windshield washer fluids

Green Car Congress

During their experiments, the scientists happened to notice that a strange odor developed when commercial cement was mixed with water. The current method is based on the width of surface cracks in concrete and a simple chemical test; however, it only gives an incomplete picture of the level of damage.

Study shows biodiesel blends in buses reduce PM, other harmful exhaust elements, EC and CO

Green Car Congress

In sum, they recommended that governments consider using blends of biodiesel in urban and commercial vehicles to enhance air quality. Positive matrix factorization (PMF) determined that four sources—oil (including fuel and engine oil), lubricant, engine parts, and ambient conditions—contributed heavily to the generation of PM in the exhaust.
