Effect of Sulphur Content of Fuel Oil on the Corrosion Wear of Diesel Engines

The purpose of this paper is to study the applicability of thermal processed fuel oil (hereafter called waste plastic disposal, or WPD) of diesel engines using low-quality fuel oil. In the experiment, stability of engine operation and components of exhaust gas, such as NOx and COx, were inspected from basic and applicable points of view. This paper illustrates a new test and result of WPD oil applied to marine diesel engines. In recent years, efforts have to be made to develop an advanced technique for recycling waste plastics in order to use scrapped plastics as fuel for diesel engines. It is very important and necessary for us to cope with the increasing calorific value and to satisfy the growing need of environment protection. The experimental fuel oil is obtained by a mixing of diesel oil, WPD, and water.

Straight vegetable oil (SVO) fuels such as palm oil, animal fat oil and waste vegetable oil were tested as fuels in a single-cylinder diesel engine to evaluate applicability to medium-speed diesel engines. Fuel-related properties of the SVO were assessed and compared with conventional marine diesel fuel oil (MDO). The total acid number (TAN) of the SVO fuels changed during a short interval in a drying oven which heated the SVO fuels to 170 degrees Celsius for several weeks. The SVO have not gone rancid any further after reaching limit. And the TAN of the SVO fuels was not related to corrosion of the parts. The SVO fuels needed to be heated to an appropriate temperature to use as fuel of the engine since the SVO fuels are more viscous than conventional diesel fuels. Both the injection period and the injection pressure increased due to low heating values of the SVO fuels. By the same token, fuel oil consumption increased over 10%. The overall exhaust emissions were lower with the SVO fuels, but NOx emission was as much as MDO at the higher loads.

The Diesel Engines (ICE) exhaust gas atmosphere noxious emissions reducing measures were introduced by the different editions and engine manufacturer publications already 25 years ago. Many of that have used up to present depend of its installation, usage and maintenance costs. For the mentioned above 25 years of emissions decreasing ways practical using on the vessels has identified it further usage consistency and profitability (efficiency). The atmosphere SОХ noxious emissions proposed decreasing way is directly connected with using fuel oil, i.e. at the fuel oil sulphur content decreasing the SОХ emission has decreasing too, that is task not for ship owners, but for petroleum-refining manufactures and bunkering companies. СО and СО2 emissions decreasing is a corner task, as a fuel oil quality and lower calorific value are identified by the carbon & hydrogen content. Thus the fuel oil carbon and hydrogen content decreasing will bring to the decreasing of a quality and lower calorific value. Therefore all of this 25 years for the vessels diesel engines (ICE) exhaust gases СО & СО2 emissions decreasing the energy efficiency task is stated. Our proposed way can allow to resolve the СО & СО2 emissions decreasing task for the engines operation parts of loads and nominal loads.
