Abstract

Diesel engines are essential for transporting heavy loads, requiring significant engine power. This study aims to evaluate the effect of adding PTT (diesel fuel conditioner) additives to Dexlite fuel, focusing on mixtures of D0, D1, and D2. Additionally, variations in fuel pre-heating and engine cooling system fluids are examined. This research employs an experimental approach with descriptive analysis. The findings indicate that the optimal torque occurs with the D2 mixture, achieving 136.57 N·m at 2267 rpm with standard coolant, 152.03 N·m at 2100 rpm with a 50%:50% fluid ratio, and 160.70 N·m at 2033 rpm with a 30%:70% fluid ratio, all without pre-heating. The optimal power values for the D2 mixture are 74.60 HP at 4600 rpm with standard fluid, 75.23 HP at 4100 rpm with a 50%:50% fluid ratio, and 78.03 HP at 4000 rpm with a 30%:70% fluid ratio, also without pre-heating. The average results show that the D1 and D2 mixtures improve torque values by 0.77% and 4.75%, respectively, and enhance power by 0.19% and 1.53% compared to pure Dexlite. In contrast, pre-heating at 50°C, 60°C, and 70°C resulted in a decrease in torque of 1.00%, 2.26%, and 3.62%, respectively, and a reduction in power of 0.56%, 2.29%, and 4.79% compared to normal temperature conditions.

Abstract

The increse in the number of motorcycles to fulfil mobility is domianted by matic type. Over time the vehicle will experience a derease in performance and appearance, triggering modification. the purpose of this study was to determine the difference in motorcycle performance with the use of standard exhaust, HPLPM 2 + catalytic converter and HPLPM mod + catalytic converter. This reaserch was conducted with a quantitative research meode with an experiemental approach, performance testing test data at engine speed of 3000-9000 rpm. Engine temperature 80 degree with pertamax fuel ocatane 92. In this study, HPLPM mod + catalytic converter produces 12,23 N.m of torque at 4500 rpm, the highest power produced by HPLPM 2 + catalytic converter 8,27 Hp at 5500 rpm. exhaust HPLPM mod + catalytic converter is able to maintain power at high rpm 7,70 Hp at 8250 rpm.

Abstract

Crude oil reserves are steadily depleting. One viable alternative is the use of biodiesel fuel in diesel engines. However, a major drawback of biodiesel is its susceptibility to degradation due to low oxidative stability. Antioxidants are compounds that inhibit or slow down the oxidation process by preventing the formation of oxidants or reducing the propagation of free radicals. This study aims to investigate the effect of adding antioxidant additives derived from Moringa oleifera bio-oil, produced through pyrolysis, to B30 biodiesel fuel at concentrations of 0, 500, 1000, and 1500 ppm on the performance of a multicylinder diesel engine. A quantitative approach was employed using an experimental method, and data analysis was conducted using descriptive analysis. The results showed that fuel consumption decreased with the addition of Moringa oleifera antioxidants, with reductions of 5.31%, 6.66%, and 7.08% at 500 ppm, 1000 ppm, and 1500 ppm, respectively, at an engine speed of 2500 rpm. The highest torque was achieved with 1000 ppm of Moringa oleifera antioxidant at 2728 rpm, reaching 111.9 Nm (an increase of 4.48%), while the highest power output was also obtained at 1000 ppm, reaching 70.9 HP at 5100 rpm (an increase of 3.2%).
