Abstract

The article considers the features of the method of research of fuel economy and environmental performance of vehicles with engines converted to run on gas fuel, which are equipped with a thermal training system based on a thermal accumulator phase transition, which is based on the implementation of system interaction of three interconnected components: information, analytical and energy. The schematic diagram of the system of thermal preparation and the information system of estimation of ways of maintenance of thermal preparation of vehicles in the conditions of operation by means of system of thermal preparation on the basis of an onboard complex (Intelligent transportation system) are presented. The peculiarity of the proposed system is that the subsystems create a common information field of the vehicle monitoring system with the heat treatment system, but operate separately from each other, based on the characteristics of the tasks they perform. Improved is the method for determining and calculating fuel consumption and emissions in exhaust gases of vehicles with engines converted to run on gas fuel, equipped with a thermal accumulator phase transition in the processes of pre-start and post-start heat treatment based on the selected model of the engine "Neutralizer". To ensure thermal preparation of vehicles with engines converted to run on gas fuel, equipped with a thermal training system based on a thermal accumulator of the phase transition, a cycle of thermal preparation in operating conditions has been developed. The influence of the thermal preparation system with the heat accumulator of the phase transition of a vehicle with an engine converted to run on gas fuel on the fuel efficiency indicators and environmental indicators in the pre-start and post-start-up processes is established.
燃气车辆发动机燃料消耗和有害物质排放测定的特点
本文分析了燃气发动机汽车燃油经济性和环境性能研究方法的特点,该方法采用基于蓄热器相变的热训练系统,实现信息、分析和能量三部分的系统交互。给出了基于车载综合体(智能交通系统)的热准备系统的原理图和运行工况下基于热准备系统的车辆热准备维护方法估计信息系统。该系统的特点是各子系统与热处理系统共同构成车辆监控系统的信息域,但根据各自任务的特点各自独立运行。改进了基于所选发动机“中和器”型号,在启动前和启动后热处理过程中配备蓄热器相变的燃气发动机汽车的油耗和废气排放量的测定和计算方法。为了保证燃气发动机车辆的热准备工作,在发动机上安装了基于相变热蓄能器的热训练系统,开发了一种运行工况热准备循环。建立了发动机转气车辆相变蓄热器热制备系统对启动前和启动后过程中燃油效率指标和环境指标的影响。
