“…The next stage of this research included an integral assessment of quality and competitiveness indicators. This assessment was conducted based on the mathematical approach and model described in [22][23][24][27][28]. The best alternative (passenger car) must meet the minimum value of the integral quality criterion.…”

This article presents theoretical studies of methods for assessing car quality indicators in the operation stage. Important criteria for determining the quality indicators of cars during the operation phase are the following: functional stability, ecology, comfort, technical solutions, and traffic safety. The problem of converting a multicriteria quality assessment to a single criterion is proposed to be solved by the method of determining a quality index. The methodology for the practical and actual implementation of this research is based on the evaluation of the quality index established on the average vehicle speed then the basic methodological principles are formulated. The quality index of a car is significantly dependent on the operating conditions. This article presents the correction coefficients for the quality index of base, hybrid, and electric vehicles, depending on the operating conditions. The studies and the proposed car quality index provide timely information on the characteristics of operating conditions, creating the necessary conditions and opportunities for automakers to improve the design of cars, promote the image of car brands, and increase sales.

Технологиялық машиналардың жұмысшы жылдамдықтарын технологияға немесе операторлық факторға қатысты белгіленген арналарда реттейді. Жылдамдықты сатылап немесе сатыламай реттеу әдістері қолданылады. Технологиялық машиналардың жұмысшы жылдамдықтарын үлкен арнада вариаторды және жылдамдықтар қорабын қолданып, ал кіші арнада вариаторды және редукторды қолданып реттеу әдістері құрылған. Жылдамдықтың өзгеру арнасын вариатордың реттеу арнасымен салыстырып, жылдамдықтың кіші немесе үлкен арнада өзгеретіні анықталады. Ені үлкен арнайы сына белдікті вариатордың кемшіліктерін ескеріп, оның орнына стандартты жетектік сына белдікті вариатор құру ұсынылған және оны құрудың негізгі мәселелері анықталған.

Problem. The tendency to reduce the working volume of internal combustion engines, which has emerged in recent years in the global automotive industry, is due to the need to improve the environmental situation and energy efficiency of road transport. Goal. The aim of the study is to increase the energy efficiency of vehicles by rationally reducing the maximum effective engine capacity. Methodology. The work uses the method of partial accelerations, implemented in a mobile registration and measurement complex, which allowed the authors to obtain an improved formula for calculating the force of aerodynamic resistance. Experimental studies of car aerodynamics were also carried out. Results. The article presents the results of the authors' research, which made it possible to prove the possibility of reducing the power of the internal combustion engine while maintaining the specified maximum speed and the specified level of indicators of the dynamic properties of cars. Originality. The relationship between the degree of use of the maximum engine power and the relative change in the effective specific fuel consumption of a carburetor gasoline engine with direct injection of gasoline and diesel is determined. Practical value. Calculations performed on the example of the ZAZ-1103 "Slavuta" car showed that a rational reduction in effective power allows for a 9.5% reduction in fuel consumption, and for an engine with direct injection of gasoline and diesel engines, this leads to an increase in fuel consumption by 6.7 % and 20.3%, respectively.
