In motor vehicles, the principles of technologically sustainable development and conceptual methods for evaluation, analysis and synthesis of high-tech and resource-saving motor vehicle processes reproduction (HTRSMVPR) taking into account their environmental safety. In the future, such methods are necessary for the innovative formation of a technologically intensive and resource-efficient micro-economy on motor vehicles.
The purpose of the work is to comprehensively improve the transport energy efficiency and environmental safety of buses for urban passenger transportation in accordance with the concept of operational and technological energy conservation and resources on passenger vehicles.
Scientific novelty of the obtained results.
• for the first time, the patterns of interrelationships of indicators of running kinematics, energy consumption and fuel consumption of adaptive-discrete movement of buses on the route (between stops) with technically regulated (according to Euro standards) indicators of emissions of harmful substances were established;
• a model of comparative analysis and operational selection of city buses and electric buses based on the criterion of transport return of their mechanical and technological procedures on the city route was formed;
• a new method of analyzing the energy intensity and fuel intensity of a multiphase transport operation is offered, which in contrast to the existing methods of analyzing the cost-effectiveness of transportation, which are based on the scheme of virtual passenger transportation, makes it possible to comprehensively solve the organizational and technological problems of improving transport processes;
• the interdependence of transport energy efficiency and conventional toxicity of urban passenger transportation and the influence of structural and technical, operational and road factors on the emissions of harmful substances of buses and electric buses during their operation in a multiphase transport operation while the implementation of urban passenger transportation were revealed.
The practical significance of the obtained results lies in the development of a number of methods for comprehensive improvement of transport energy efficiency and environmental safety of urban passenger transportation:
– a method of operational improvement of the effectiveness of technological influences of machine procedures for electric buses, taking into account operational and road factors;
– a method of comprehensive analysis of transport energy efficiency and conventional toxicity of buses on city routes.
