US study of miners links heavy exposure to diesel exhaust to increased risk of lung cancer death; researchers suggest implications for urban areas with high exhaust concentrations

Green Car Congress

In a study of non-metal miners in the US, federal government scientists report that heavy exposure to diesel exhaust increased risk of death from lung cancer. For never-smokers, risk of lung cancer death increased with increasing diesel exhaust exposure. effect of diesel exhaust exposure on lung cancer mortality in.

International automotive researchers emphasize the importance of continued development of the internal combustion engine

Green Car Congress

Top of the list is engine efficiency, with a wide range of technical opportunities: Combustion system. This could be paired with combustion technologies with highly diluted combustion (stoichiometric with exhaust gas recirculation (EGR) as well as lean burn with excess-air ratios above 2). Engine lubrication.

More classic regression techniques are also claimed in machine learning but from a historical perspective are more heavily rooted in statistics. The mapping shown in the figure is intended to be representative, but not exhaustive. In some cases, the relationships could actually be thought of like a Venn diagram. —Lux Research.

Study Measures the Effect of Fischer-Tropsch Synthetic Jet Fuel on Emissions

Green Car Congress

The team used FT fuel derived from natural gas, and ran the different fuels and blend in a PW308 business jet class gas turbine engine over a range of engine power conditions to provide exhaust gas for analysis. The NO x reduction is greater than can be explained by experimental uncertainty and is therefore statistically significant.

Electric Ram 1500 Revolution BEV Concept pickup truck revealed at CES

Charged EVs

Ram says it can charge at 800 volts, claiming users could add 100 miles of range in 10 minutes (a carefully chosen statistic that assumes a largely depleted pack, optimum temperatures, and other ideal conditions). But Koval hinted at further powertrain options to come. Expressive styling, ‘white-knuckle’ performance.
