The analysis of fuel efficiency makes it possible to make a reasonable choice of the rolling stock of a motor transport company and its rational use when performing transport work.
The temperature regime of the units and the associated change in the fuel efficiency of cars depends both on the design parameters and on the conditions in which the cars are operated, and primarily on the ambient temperature.
A change in ambient temperature by 10 ° C leads to the fact that the total resistance to movement changes by about 8-10%, fuel consumption by 6-7%. If the ambient temperature decreases by 30 ° C, fuel consumption may increase by 25%. When the exhaust gas temperature increases by 10 ° C, the engine power decreases by 1.8-2.2% (more for diesels).
Keywords
