Analysis of practical calculation methods of external speed characteristics of engine

This article describes developing an external speed of the engine characteristics for teaching the subject of "vehicle construction" at technical higher education institutions. And it is explained easily for bachelor or independent learners in the field of automobiles. By using this method (given above). Projecting the external speed of the engine, solving the construction problems, and teaching based on the subject is able to get a good result. Modern designs of cars have high reliability with the ability to automatically adapt to specific operating conditions. The analysis of the level of use of the constructive potential of heavy vehicles in operation shows that there is a significant reserve for their improvement. The external speed characteristic is used to obtain complete information about the engine parameters. The external speed characteristic is a graph of the dependence of engine power and torque on the frequency of crankshaft revolution or angular speed.
