Abstract

In the course of the present study we devised an indicator of the adaptability of automobiles to operation under winter conditions based on the engine cooling rate, and a procedure of its estimation. A three-level grading assessment of the adaptability of automobiles to operation under winter conditions based on the engine cooling rate is proposed. We established an exponential form of the mathematical model for a change in the engine cooling rate, which takes into consideration speed of the wind that blows over the engine, its mass and heat insulation, as well as arrangement density in the under-hood space.

Numerical values for the parameters of the mathematical model were determined.

Results of the research allow us to estimate the limits of operational conditions of the rational use of automobiles when cooling rate of an idle engine does not exceed the critical value, and, therefore, fuel consumption used by the engine to maintain a temperature mode under given operating conditions during a short stop is minimal.
