Article contains results of the theoretical analysis revealed by practice of ZIL trucks drawback. Stability of work of the engine is analyzed at acceleration with gear shift. The inequality describing a condition of engine steady work is deduced. In article the kinematic coordination of various models of ZIL trucks is considered and it is noticed that truck ZIL-5301BE has kinematic in coordination of engine and transmission. Ways of its overcoming are shown. The Law on higher education and after graduate professional education of Russian Federation as one of the tasks of higher institute provides the use of scientific researches in educational process. The authors offer the results to students of Moscow state industrial university in the lectures on special disciplines.
