INDICATORS FOR ASSESSING THE EFFICIENCY OF FUEL USE IN ROAD TRANSPORT

Аннотация

This article discusses the evaluation of fuel efficiency indicators in road transport. At the same time, the main criterion for evaluating the efficiency of the use of automotive fuel is the specific fuel consumption in grams per unit of transport work. The energy intensity is calculated by dividing the total amount of energy consumed by the fuel by the transport work performed at the same time. KEYWORDS: Efficiency of use, energy intensity of transportation, specific fuel consumption, the method of conditional natural meters, the efficiency of a new design, a simplified meter. INTRODUCTION economic efficiency of road transport. The analysis of fuel efficiency makes it possible to Fuel efficiency indicators characterize the make a reasonable choice of the rolling stock consumer qualities of the car. The cost of fuel of a motor transport company and its rational is up to 20-30% of all transportation costs, so use when performing transport work. The fuel efficiency has a significant impact on the main measure of the fuel efficiency of a car in “INDICATORS FOR ASSESSING THE EFFICIENCY OF FUEL USE IN ROAD TRANSPORT” P age 13 | 6 most countries is fuel consumption in liters If necessary, the energy intensity is expressed per 100 km of distance traveled – travel fuel in electrical units of measurement using consumption. transferable equivalents: For road transport, the indicators for 1 kcal = 1/860 kw/hour = 4186,8 joule assessing the efficiency of fuel use include: The determination of the energy intensity of the energy intensity of transportation, linear transportation is essential when assessing the fuel consumption rates per 100 km of vehicle fuel efficiency of cars and buses of a new mileage and specific fuel consumption per design, especially if a new type of engine is unit of transport work. used. However, when analyzing the work of In the practice of car operation, a simplified motor transport enterprises to determine the fuel efficiency meter has become widespread, efficiency of the use of motor fuel, the which is the fuel consumption rate per unit of indicator of the energy intensity of the distance traveled by the car. These transportation is not applied. standards are necessary for accounting and This is explained by a number of reasons: control of fuel consumption at motor transport enterprises. - the unit of measurement of energy intensity in kilocalories is not comparable with the
