  IMPROVING THE COOLING SYSTEM OF THE DAMAS VEHICLE The Damas vehicle, widely used in Uzbekistan for both commercial and personal purposes, relies on a traditional liquid cooling system. While functional, the current mechanical fan system consumes engine power unnecessarily and leads to inefficiencies in fuel consumption, especially in varying climate conditions. This study proposes a redesign of the cooling system through the implementation of an electric fan controlled by a thermostat, synchronized with engine temperature. The new system aims to reduce fuel consumption, increase engine efficiency, and improve environmental performance. The research involved analysis of the existing system, prototyping, real-world testing, and economic evaluation. The results demonstrate that the redesigned system significantly improves thermal management and fuel efficiency.

  THE IMPORTANCE OF THE SPOILER IN AUTOMOTIVE AERODYNAMICS Aerodynamic efficiency is essential in modern vehicle design, contributing significantly to fuel economy, stability, and high-speed performance. Spoilers are one of the most widely used aerodynamic components, primarily aimed at reducing lift and managing airflow over the vehicle. This study investigates the aerodynamic role of spoilers on passenger cars by analyzing their effect on drag coefficient, lift force, and stability. Using wind tunnel testing and computational simulations, the paper compares vehicles with and without spoilers under various conditions. The results reveal that properly designed spoilers can reduce aerodynamic lift by over 25% and improve overall vehicle control at high speeds. The research also highlights the interrelationship between spoiler geometry, airflow behavior, and vehicle dynamics.

  A COMPARATIVE STUDY OF ASSOCIATIVE EXPERIENCE AND THEMATIC GROUPING PRINCIPLES IN LEARNER’S EXPLANATORY DICTIONARIES (IN THE CASE OF ENGLISH AND UZBEK LANGUAGES) This article presents a comparative analysis of the principles of associative experience and thematic grouping—two key approaches in the structure of modern learner’s explanatory dictionaries—using examples from English and Uzbek. The study examines the role of these principles from linguistic and psycholinguistic perspectives, focusing on how they address the cognitive needs of language learners, reflect the mental organization of lexical items, and contribute to the effectiveness of vocabulary acquisition. The research analyzes the structure and methodological approaches of major learner’s dictionaries such as the Oxford Wordpower Dictionary (English) and the Izohli Lug‘at (Uzbek), evaluating their user-friendliness, ability to form semantic fields, and functionality in language instruction. Furthermore, the article explores how lexical items in these dictionaries are presented in terms of semantic, associative, and thematic relationships, and assesses the impact of these approaches on the development of learners’ vocabulary.

  PROSPECTS FOR THE USE OF POLYMER MATERIALS IN CAR REPAIR It is difficult to imagine the designs of modern vehicles without polymer materials. The use of these materials, along with streamlining the designs of technical means, reducing their mass, and increasing operational reliability, opens a wide way to reducing production costs and labor costs. The widespread use of polymer materials is due to their ability to directly replace precious metals and wood materials, often surpassing them.
