engine operatively coupled to a wellsite apparatus for transmission of power from the wellsite diesel engine to the wellsite apparatus; and injecting at least one component of natural gas into the wellsite diesel engine, thereby combusting the natural gas component in the wellsite diesel engine....
a finding which reflected growing concerns in Germany over the environmental impact of large diesel SUVs with regards to their CO2 and nitrogen oxide (NOx) emissions. The total consumption of highly-motorized petrol vehicles rose as well (plus ...
independent carriersThe research aims at measuring the possible environmental and economic benefits generated by renewing the Brazilian autonomous truck fleet. The article focuses on two specific points: the reduction of CO2 emissions and also the diminution of diesel consumption. The Top Down model ...
While petrol usage declined by 10 million liters to a total of about one billion liters, this was surpassed considerably by a 20-million-liter increase in the use of diesel fuel, which totalled about 4 billion liters. The VCO said this will have a more noticeable impact on emissions total...
National estimates of diesel fuel consumption agreed with FEUS within half a percent. Fossil fuel GHG emissions on Canadian farms dropped by 22% from 1986 to 2001 and by 14% from 1991 to 2001. By far the greatest changes have occurred in the Prairies where the most noticeable shift toward ...
This paper reviews the influence of different factors that affect fuel consumption and CO2 emissions on the road and in the laboratory. Factors such as driving behaviour, vehicle configuration and traffic conditions are reconfirmed as highly influential. Neglected factors (e.g. side winds, rain, ...
of diesel engines and, in particular, the high efficiency of the combustion process and the diesel oxidation catalyst allows to compute the CO2 emissions from the fuel consumption estimation of the electronic control unit by applying the carbon balance method assuming negligible HC and CO emissions....

Euro 6 GDI engines < 1.4ℓ delivered ~ 17% CO2 reduction compared to Port Fuel Injection (PFI). Gasoline vehicles delivered an 86–96% reduction in NOx emissions compared to diesel cars. The average urban NOx emission from Euro 6 diesel vehicles 0.44 (sd. 0.44) g km− 1 was 11 ...
