Abstract

This study aimed to analyze the effect of Fuel Oil Additive (FOA) on the performance and fuel consumption of diesel engines fueled with B20 biodiesel. The research used an experimental quantitative method by comparing the Specific Fuel Consumption (SFC) values of diesel engines operating with B20 fuel and B20 mixed with FOA under different loading conditions. The tests were conducted on a 6DV-32 diesel engine generator with loading variations of 50%, 75%, and 100%. The results showed that the addition of FOA improved fuel efficiency at medium and high engine loads. At 75% load, the SFC value decreased from 0.309 liter/kWh to 0.291 liter/kWh, representing a reduction of 5.82%. At 100% load, the SFC value decreased significantly from 0.292 liter/kWh to 0.246 liter/kWh, with an efficiency improvement of 15.75%. However, at 50% load, the SFC value increased from 0.312 liter/kWh to 0.329 liter/kWh or by 5.45%, indicating that FOA performance was less effective at low engine loads. The findings indicate that the use of Fuel Oil Additive enhances combustion quality and improves fuel consumption efficiency, particularly under high loading conditions. Therefore, B20+FOA has the potential to be applied as an alternative fuel solution for improving diesel engine operational efficiency.

Abstract

This research evaluates the performance of a diesel engine based on the analysis of Indicated Horse Power (IHP) using the Pressure Combustion Analysis (PCA) method. The study applied a quantitative descriptive approach by measuring combustion pressure in each cylinder under stable operating conditions. Data acquisition was carried out using the Haliza Machinery & Diesel Engine Analyzer combined with SoftHaliza software for processing combustion characteristics and engine performance parameters. The investigation focused on several variables, including combustion pressure, ignition delay, pressure at crank angle 340°, combustion stability, and IHP distribution among cylinders. The results indicated that the combustion process in all cylinders operated under normal conditions with relatively stable pressure patterns. No significant abnormalities such as excessive ignition delay, combustion instability, or diesel knocking were identified during testing. The analysis also showed that the total Indicated Horse Power generated by the engine reached 1730.3 kW, equivalent to approximately 87% of the generator output capacity of 4000 kW. In addition, the uniformity of combustion pressure among cylinders demonstrated that the fuel injection and combustion systems were functioning properly. Overall, the PCA method proved effective for monitoring combustion characteristics and evaluating diesel engine performance. The method can therefore be implemented as part of a predictive maintenance strategy to improve operational reliability, combustion efficiency, and engine durability in diesel power generation systems.

Abstract

Electricity demand in Luwuk Banggai Sulawesi Tengah has continued to increase, requiring efficient operation of diesel power plants. The use of Biodiesel B35 as an alternative fuel introduces challenges related to lower fuel efficiency compared to conventional diesel. This study aims to evaluate the effect of Aderco additive on improving fuel efficiency in diesel engines at Luwuk Diesel Power Plant. A field experimental method was applied using a pre-test and post-test design by comparing engine performance before and after additive application. The analysis focuses on Specific Fuel Consumption as the main performance indicator, calculated from fuel consumption and power output under similar operating conditions. The results show that the use of Aderco additive reduces Specific Fuel Consumption in all tested units. Medium-speed engines demonstrate a more significant improvement, with a maximum reduction of 4.68%, while high-speed engines show a smaller decrease ranging from 1.02% to 1.35%. These findings indicate that the effectiveness of the additive is influenced by engine speed and combustion duration. In conclusion, the Aderco additive effectively improves fuel efficiency in diesel engines, particularly in medium-speed units, without requiring modifications to engine design.

Abstract

The increasing demand for electrical energy requires thermal power plants to improve operational efficiency while reducing fuel consumption and energy losses. This study investigates the effect of fuel oil additive on boiler efficiency and fuel utilization in a steam power plant system. The research applied an experimental quantitative approach using a comparative before–after method by evaluating boiler performance prior to and following the application of the additive. Operational data were collected directly from the plant monitoring system, including boiler load, fuel consumption, steam generation, flue gas conditions, and boiler efficiency parameters. Boiler efficiency calculations were conducted using the ASME PTC 4.1 input–output performance test method. The results indicate that the application of fuel oil additive improved boiler efficiency from 93.357% to 98.922%, representing an increase of 5.565%. In addition, the plant load increased from 79.50 MW to 81.00 MW after additive utilization. The improvement in performance is associated with better fuel atomization, enhanced combustion quality, and reduced heat losses during boiler operation. The findings demonstrate that the use of fuel oil additive can contribute to more efficient boiler operation, lower fuel consumption, and improved thermal performance in steam power plants.

Abstract

His study aims to analyze combustion pressure characteristics in a diesel engine using the Pressure Combustion Analysis (PCA) method. The research employed a quantitative descriptive approach through direct measurement of combustion pressure in each cylinder of a Sulzer 12 ZV 40/48 diesel engine under constant operating load conditions. The analyzed parameters included peak combustion pressure, combustion pressure balance, ignition delay, pressure at crank angle 340°, and indications of abnormal combustion. Data acquisition was conducted using Haliza Machinery & Diesel Engine Analyzer and processed using SoftHaliza software. The results showed that the average combustion pressure reached 59.33 bar with pressure deviations among cylinders remaining below the allowable limit, indicating that the overall combustion condition was still within normal operating standards. Comparative analysis before and after the application of fuel additive demonstrated an increase in average combustion pressure from 57.91 bar to 59.33 bar, indicating improved combustion performance and smoother combustion characteristics. However, several cylinders still exhibited indications of incomplete combustion and combustion pressure imbalance caused by variations in fuel injection and combustion quality. In addition, the PCA method proved effective for early detection of ignition delay, combustion abnormalities, and potential cylinder performance degradation. Therefore, Pressure Combustion Analysis can be applied as an effective predictive maintenance method to improve diesel engine reliability and operational efficiency.
