Investigation of the Effects of Using Low Sulfur and Rural Diesel as Diesel Fuel in Tractors on Engine/emissions

Abstract

Energy is one of the main factors that ensure the formation of production, development, and economic conditions between countries. Although fossil fuels pose some problems in terms of the environment and human health, they still have great use in meeting the energy demand in the world. Although there are many studies on alternative fuels in today's conditions, diesel engines are more preferred by the countries in heavy-duty vehicles (construction machines, tractors, and combine harvesters) operating in all kinds of commercial and land conditions that are used in transportation. Diesel engines are more preferred in developing countries due to their high torque and low fuel consumption. For this reason, efficiency, operating parameters, and reducing the environmental emissions of diesel engines used in our country are important. Since agriculture is one of the most important fields of activity in our country, in this study, the engine's characteristics and the effects on the exhaust emissions of the rural diesel used in the tractor and the low-sulfur diesel fuel were experimentally investigated. The maximum torque (1400rpm) used during the field plow of the tractor, which is available in Çerkezköy Hattat Tractor Factory R&D Center, and the maximum power (2100rpm) under other driving conditions were tested with both diesel fuels. When the results of the experiments were compared, it was seen that higher torque and power were obtained with the use of low sulfur diesel fuel, while harmful exhaust emissions were lower than rural diesel fuel. However, when the engine's fuel consumption is compared, it has been determined that rural diesel is consumed less than low sulfur diesel.
