China study connects ozone pollution to cardiovascular health

Green Car Congress

Exposure to ozone, long associated with impaired lung function, is also connected to health changes that can cause cardiovascular disease such as heart attack, high blood pressure and stroke, according to a new study of Chinese adults. The findings associated ozone exposure with markers of platelet activation and increased blood pressure.

times the route-averaged emissions factor in grams/km without significant dependence on bus type or climate. These sensors are necessary for proper exhaust aftertreatment operation—NO x input and output measurements direct the system’s urea injection for the catalytic reduction process.

Monash study on solar-driven electrolysis for green hydrogen production cautions on life-cycle emissions and EROI

Green Car Congress

An important consideration of solar-electrolysis in the context of climate mitigation is the enormity of upscaling required—both at the global scale with respect to the investment, land area, materials, and embodied energy; and at the project scale with respect to the potential localised impacts of gigawatt scale plants.

IPG to demo Flameless Ceramic Turbine for clean, off-grid power in EV charging

Green Car Congress

But, in many high-use areas and remote locations, upgrading grid connections to meet future charging demand is not practical or commercially viable. IPG‘s flameless combustor uses the turbine exhaust and high heat transfer effectiveness through the IPG regenerator unit. —IPG CEO Toby Gill.

Environment Canada/MECA team assesses black carbon emissions in GDI engine exhaust; evaluation of prototype gasoline particulate filter

Green Car Congress

In addition, the inhomogeneity of the fuel mixture under stratified operation in GDI engines during the compression stroke tends to contribute to higher particulate emissions compared to the exhaust emissions from traditional PFI engines.

Second-generation Audi A7 Sportback features standard 48V MHEV system with gasoline or diesel engines

Green Car Congress

The new three-liter V6 exhaust end lies inside the 90° vee; the short gas paths and the twin scroll charger, which prevents unwanted interactions between the gas columns, guarantee spontaneous throttle response. This is due in part to the new tube guide in the dual-branch exhaust system that largely eliminates hum frequencies.
