Abstract

Presented are the results of experimental studies of the heat treatment system of a vehicle gasoline engine, which is heated to operating temperatures on gasoline, and subsequent operation on liquefied oil gas. The main element of the heat preparation system is a phase transition heat accumulator. The research task to be solved is to minimize the time of heat preparation of the vehicle gasoline engine and, therefore, to reduce gasoline consumption in warm-up modes. To ensure remote registration of vehicle parameters and control of heat preparation processes, an information system for monitoring and control of heat preparation processes of a vehicle engine with a heat accumulator was developed and used. During the research, a gasoline-powered vehicle was used with additionally installed gas equipment. The use of a phase transition heat accumulator in the heat preparation system of a vehicle gasoline engine (operating both on gasoline and on liquefied gas fuel) has confirmed a significant improvement in fuel economy. For this, the engine heat preparation should be carried out immediately before starting from an additional heat source to the coolant temperature in the cooling system up to 50° C. The research results have confirmed the capabilities of the system under study to significantly reduce the time of heat preparation and reduce the vehicle gasoline engine fuel consumption running on gasoline and liquefied gas fuel under operating conditions. The phase transition heat accumulator in the heat preparation system of a vehicle gasoline engine (operating both on gasoline and on liquefied gas fuel) reduces the time required to heat the coolant to 50° C and gas consumption to ensure the transition to gas fuel when using various modes (options) of heat preparation in operating conditions.
汽油、液化油供气系统车用发动机热制备工艺的改进
本文介绍了一种车用汽油机的热处理系统的实验研究结果,该系统在汽油上加热到工作温度,然后在液化石油气上运行。热制备系统的主要元件是相变蓄热器。要解决的研究任务是最大限度地减少车用汽油机的热准备时间,从而减少预热模式下的汽油消耗。为实现整车参数的远程登记和整车热备过程的远程控制,开发并应用了一种车载蓄热器发动机热备过程监控信息系统。在研究过程中,使用了一辆汽油动力汽车,并额外安装了燃气设备。将相变蓄热器应用于车用汽油机(汽油和液化气两种燃料)的热准备系统,大大提高了燃油经济性。为此,应在从附加热源启动前立即进行发动机热准备,使冷却系统中的冷却剂温度达到50℃。研究结果证实了所研究系统能够显著缩短热准备时间,并降低在运行条件下使用汽油和液化气燃料运行的车用汽油机油耗。一种车用汽油发动机(同时使用汽油和液化气燃料)的供热系统中的相变蓄热器,在运行条件下使用各种供热模式(选项)时,减少了将冷却剂加热到50℃所需的时间和确保向燃气燃料过渡所需的燃气消耗。
