Method for Determining the Environmental Performance of a Vehicle During its Design

Abstract

The article addresses a critical issue in modern automotive engineering — determining the environmental indicators of a vehicle during its design phase. Given the increasing number of vehicles in use worldwide, their impact on the environment is becoming increasingly significant. The authors note that the number of cars has exceeded 1.5 billion and continues to grow. This highlights the need to develop effective methods for assessing the environmental safety of vehicles even before they reach the market.

The aim of the study is to develop a reliable method for calculating the environmental indicators of a vehicle during its design. Since there is no physical vehicle available for testing at the design stage, the determination of environmental indicators can only be achieved through calculation methods. The article proposes a method that allows for the calculation of harmful emissions per unit of distance traveled by the vehicle. This method not only helps to predict the level of pollution but also takes into account the impact of the vehicle's structural parameters, such as engine displacement, transmission gear ratios, wheel radius, and more.

The proposed method enables the determination of acceptable levels of harmful component concentrations based on established standards, without the need for full-scale vehicle testing, significantly simplifying the assessment process.

The conclusions emphasize that the developed method not only allows for assessing the vehicle's compliance with environmental requirements but also contributes to improving its environmental performance during the development phase. This approach enables automotive engineers to make more environmentally sound decisions and ensure compliance with modern environmental protection standards.
