DEVELOPMENT OF A MECHANISM FOR DETERMINING THE DOWNTIME AT REFUELING COMPRESSED NATURAL GAS OF LPG CARS
Abstract
One of the problems that arise during the operation of gas-balloon vehicles running on compressed natural gas is downtime associated with refueling with motor fuel. Accounting for downtime data is a necessary task when solving the issue of vehicle routing in the transportation of goods and passengers. At motor transport enterprises, this factor is often not taken into account or is determined subjectively based on experience and intuition. This fact leads to an increase in unaccounted for costs and a decrease in the profits of enterprises from transportation activities. To solve this problem, the authors of these studies proposed a method for determining the time for filling an automobile gas cylinder with compressed natural gas (CNG), taking into account factors such as pressure in the gas cylinder before filling, ambient temperature and gas column performance. To implement the proposed methodology in the work of motor transport enterprises, an algorithm was developed for determining the downtime of a gas-balloon vehicle when refueling CNG. The methodology and algorithm presented in the article formed the basis of the software product developed by the authors for determining the time to fill an automobile gas cylinder with compressed natural gas, which allows automatic calculation in the conditions of a motor transport enterprise. The use of the proposed software product will increase the productivity of operators involved in the accounting of the operating time of vehicles. Purpose development of a mechanism for recording the downtime of vehicles during the transportation of an automobile gas cylinder with compressed natural gas. Methodology of the article: mathematical methods, as well as statistical methods of analysis. Results: A method for determining the time for filling an automobile gas cylinder with compressed natural gas has been developed, an algorithm for determining the downtime of a gas cylinder vehicle when refueling CNG has been developed, a software product has been developed for determining the time for filling an automobile gas cylinder with compressed natural gas Practical implications: it is advisable to apply the results obtained in the operational planning of the operation of vehicles at enterprises operating rolling stock using CNG as a motor fuel.
