ICCT: real-world NOx from Euro 6 diesel passenger cars more than 2x Euro VI diesel trucks

Green Car Congress

In Europe, the average amount of NO x present in exhaust emissions from modern diesel passenger cars under real-world conditions is more than double the levels from modern trucks and buses, according to a new briefing paper released by the independent research organization International Council on Clean Transportation (ICCT).

VTT study finds no significant difference in car fuel consumption between E10 and E5

Green Car Congress

A study conducted by VTT Technical Research Center of Finland indicates that there is practically no difference between commercial gasoline grades 95E10 and 98E5 sold in Finland as regards fuel consumption in normal driving. The results showed 4.7% for the E5-grade and 9.4% for the E10 grade.

Study finds that optimizing engine parameters for renewable diesel can reduce PM and NOx both by more than 25%

Green Car Congress

A team of researchers in Finland reports that by adjusting engine parameters for the use of hydrogenated vegetable oil (HVO) renewable diesel fuel across a range of loads (50%, 75%, and 100%), particulate matter and NO x emissions can both be reduced by more than 25% relative to the values from using HVO with standard engine conditions.
