Investigation on characteristics of exhaust and evaporative emissions from passenger cars fueled with gasoline/methanol blends

Evaluation on toxic reduction and fuel economy of a gasoline direct injection- (GDI-) powered passenger car fueled with methanol–gasoline blends with various substitution ratios

“…The majority of previous works had reported decreased CO emission with the introduction of gasohol, while HC and NOx emissions were maintained at a generally similar level when compared with gasoline baseline. Remarkable increases in NOx emissions of gasohol-fueled vehicles were reported by references [20,22]. This phenomenon may be attributed to the fact that both authors used methanol-gasoline blends with no additive as test fuel.…”

“…[21]. On apparatus and methodology for the analysis of carbonyl components and volatile organic compounds (VOCs), papers [20,22] have spent particular paragraphs to discuss in-depth. Here, Eq.…”

“…In this research, M15 was proved an effective way to reduce exhaust-borne particles from both PFI-and GDI-powered vehicle. Another work done by Dai et al devoted to pipe-out and evaporative emissions from cars burning gasohol [22]. An increment of 85% NOx and 63% evaporative THC was observed by conducting chassis-dyno tests and precise weighting in sealed chamber.…”

Emissions of exhaust gases and health of the person

“…The list of pollutants in exhaust gases depends on engine types, operating mode, technical condition, fuel quality [12,13], as well as service classification. Harmful substances in the operation of mobile vehicles enter the air with exhaust gases, fumes from fuel systems and during refueling.…”

Effects of engine misfire on regulated, unregulated emissions from a methanol-fueled vehicle and its ozone forming potential

“…The authors also replaced the catalyst originally installed on the test vehicle with a new one and measured tailpipe formaldehyde concentrations, which indicated a comparatively higher conversion efficiency of the new catalyst. [29] measured evaporative and tailpipe emissions from three passenger cars burning gasoline and M15. It was astonished that methanol content within the evaporative pollutants surged approximately 127 times when M15 substituted gasoline, tailpipe NOx emissions, carbonyls and VOCs also to various degrees increased compared to gasoline baseline.…”
