For further details of the official fuel consumption
figures and official specific CO2 emissions of new cars, please refer to the "Manual on fuel consumption
, CO2 emissions and power consumption of new cars", available free of charge at all sales outlets, from Deutsche Automobil Treuhand GmbH (DAT), Hellmuth-Hirth-Str.
The fuel consumption
is used to determine the car taxes, and it can therefore be of great importance for the car's total price.
Driving strategies are the answer to manage engine and transmission, aiming to reduce fuel consumption
, and therefore, obtain higher efficiency in diesel oil use (Howard et al., 2013).
Aside from daily trip tickers, monthly report of fuel consumption
was likewise not submitted to COA, thus, violating COA Circular 77-61.
Three engine/transmission variants are offered from launch: the BMW X2 sDrive20i petrol model with 141 kW / 192 hp (fuel consumption
combined: 5.9 - 5.5 l/100 km [47.9 - 51.4 mpg imp]; CO2 emissions combined: 134 - 126 g/km)2, plus the X2 xDrive20d diesel variant with 140 kW / 190 hp (fuel consumption
combined: 4.8 - 4.6 l/100 km [58.9 - 61.4 mpg imp]; CO2 emissions combined: 126 - 121 g/km)2 and X2 xDrive25d diesel with 170 kW / 231 hp (fuel consumption
combined: 5.3 - 5.1 l/100 km [53.3 - 55.4 mpg imp]; CO2 emissions combined: 139 - 133 g/km)2.
Numerical empirical studies show a positive relationship between vehicle emissions and fuel consumption
with delays at traffic signals [14, 15].
Due to the higher injected water mass, corresponding to an increase of the injection duration from ~12[degrees] CA to ~29[degrees] CA, earlier MFB50s and thus, together with the higher CR, lower minimal fuel consumption
(indicated specific fuel consumption
corrected to a heating value of 42.5 MJ/kg - [ISFC.sub.42.5 MJ/kg]) were measured with the higher CR.
The summary of the ANOVA of the results of engine speed, hourly and specific fuel consumption
at different travel speeds and load levels applied on the tractor, is shown in table 1.
The dependence of the increase in fuel consumption
in the transition process as compared with the established operation mode of diesel was set as a result of experimental studies.
Initially the fuel consumption
can be analyzed by calculating that how much fuel is being utilized for a particular field operation .
The protocol defines the means (necessary equipment) and methods (measurement and processing) that should be systematically applied to calculate the average real-life fuel consumption
of the average customer.
A Method to correct the deviation between the measurement and calculated fuel consumption
had been developed in studies  .
