The contribution of diesel, gasoline and compressed natural gas(CNG) to total CO, CO_2 and NO X emissions were 7:84:9, 50:48:2 and 58:41:1respectively. The present work indicated that the age and the maintenance of vehicle both are important factors in emission assessment therefore, ...

Firstly, this paper investigates the real-world time trend of CO2 emissions from passenger cars in Europe in the period from 1995 to 2015, which we refer to as the European “diesel boom”. For the first time, we use real-world emission factors based on Tietge et al. (2017) to calcula...
The average chemical formula for common diesel fuel is C12H23, ranging approximately from C10H20 to C15H28.Petrol (Gasoline): 2 C8H18 + 25 O2 --> 16 CO2 + 18 H2O + energy2 mol C8H18(114 g/mol) --> 16 mol CO2(44 g/mol) => 2*114=228g --> 16*44=704g => 1000/228*...
measures. The retirement of yellow-label and old vehicles contributed 0.06 Gt to CO2reduction. More than 26 million yellow-label and old vehicles (i.e., gasoline vehicles that do not meet the China III emission standards and diesel vehicles that do not meet the China IV emission standards) ...
The analysis reveals a reduction in road transport CO2 emissions and diesel consumption as a result of an uptake of more efficient truck technologies. In particular, LNG trucks are favored because of the lower emission factor of natural gas relative to that of diesel. Implementing progressively ...
It is exempted from VOC classification and can be used as raw material for producing valuable chemicals, including aromatic polycarbonate, and qualifies as an octane booster component in gasoline and diesel. It is a safer and nontoxic substitute of well-established methylating-carbonylating...
Real-world emissions and fuel consumption of diesel buses and trucks in Macao: From on-road measurement to policy implications A total of 13 diesel buses and 12 diesel trucks in Macao were tested using portable emission measurement systems (PEMS) including a SEMTECH-DS for gaseous ... Xiaomeng...
(CEF_{j}\)is carbon emission factor for the energy ofj, and the\(COF\)is the carbon oxidation coefficient. In addition, considering that when carbon is oxidized to CO2, the molecular weight changes from 12 to 44. Therefore, the corresponding conversion is performed when calculating CO2...
