Numerical investigation of the fuel consumption in acceleration process at uniform motion is made by using elaborated specified theoretical models and a program for computer simulation of the automobile, its aggregates and running processes. The results of the computer simulation are compared with experimental data of the fuel consumption in the same working conditions. The experiments are implemented at two regimes with different intensity of acceleration. The analysis of the obtained results shows that theoretical and experimental data have comparatively good coincidence. That is a reason to accept, that the model and algorithm of the program may be used for investigation of the economy indicators of mobile machines with a benzine engine. It is established theoretically and experimentally that for accelerating regimes with normal intensity, the fuel consumption increases by 1.5 to 2 times compared with those at uniform motion. |
