Abstract

The energy crisis and the threat of global climate change have spurred various research efforts and alternative initiatives to find substitutes for fossil fuels, improve energy efficiency, and reduce emissions, especially greenhouse gases. The shipping industry is one of the contributors to global emissions that has received particular attention due to the increasing demand for maritime transportation services. The use of natural gas is considered a potential solution due to its relatively clean nature, abundant availability, and competitive pricing. The CNG-Diesel Dual Fuel Engine design is developed with the principle of using natural gas as an alternative fuel without replacing the existing diesel engine. Minimal modifications are made to the intake manifold to accommodate CNG entry. Despite its advantages, the development of dual fuel engines faces challenges, such as increased methane emissions due to the potential for incomplete combustion. This research conducts experimental studies on the use of a Venturi-like mixer in the intake manifold to enhance the homogeneity of the CNG-air mixture before entering the combustion chamber. Testing the mixer's influence is carried out under various CNG injection durations at low and high engine loads at constant speeds. The results indicate that the addition of the mixer does not immediately improve combustion quality or reduce emissions. Attention to conditioning the homogenous mixture at the required air-fuel ratio before entering the combustion chamber is crucial. The selection of the appropriate mixer design, diameter size, and placement of holes needs careful consideration

Abstract

The pursuit of achieving zero carbon emissions by 2050 has led to the implementation of green technologies in the maritime industry. One crucial aspect is the adoption of alternative fuels, with a focus on non-fossil fuels to enhance energy efficiency and minimize emissions during ship operations. This study explores the innovative dual fuel diesel – Compressed Natural Gas (CNG) technology, which offers relatively low emissions with uncomplicated modifications to the diesel engine. CNG is injected into the intake manifold, addressing the need for cleaner fuel options. However, the evolution of this technology has encountered challenges such as methane slip resulting from incomplete combustion. This research proposes an intervention using hydrogen within the combustion chamber to improve combustion quality. Oxy-hydrogen gas (HHO), a carbon-free fuel derived from water through electrolysis, is considered as a potential solution. The utilization of HHO serves as a substitute for pure H2 due to its more feasible production and application, considering the global limitations in hydrogen storage and usage in transportation. The study aims to investigate the impact of HHO on the performance and emissions of dual fuel engines. Experimental tests are conducted under low loads to simulate critical operational points of the engine. Results indicate that the dual fuel system exhibits significant fuel savings, particularly with increasing injection duration. However, the need for additional oxygen to enhance combustion perfection must be balanced. HHO injection demonstrates the potential to improve engine performance, leveraging the oxygen content in HHO and the positive characteristics of hydrogen with its high Lower Heating Value (LHV). Furthermore, the research suggests that HHO injection can mitigate methane slip issues associated with dual fuel engine operations, offering a promising avenue for emission reduction

Abstract

A braking system in a vehicle has a very important role in maintaining the safety of drivers and passengers, and preventing accidents. The brake system functions to reduce speed (slow down) and stop the vehicle. A good braking system provides safety and comfort for the drivers. Therefore, it is necessary to design the right braking system for “Sakera” car. In this study, an analysis and calculation of the braking system was carried out to determine the required braking force at a speed of 50 km/hour and other speeds in a distance of 15 m. The data taken in this study was the specification of the braking system used in the Sakera car. The braking system analysis was carried out on flat roads with varying speeds, namely 30 km/h, 35 km/h, 40 km/h, 45 km/h, and 50 km/h with a distance of 15 m for braking. The conclusions of the analysis were obtained, namely the greater the speed of Sakera's car, the greater the braking force to stop the car, the hydraulic pressure on the hose, and the force of the driver's feet, as well as the braking force needed on road conditions with a slope angle of 20º, which is 839.362 N.

Abstract

The gas turbine is one of the most widely used equipment in oil and gas industries as an electric generator driving system. To maintain the reliability and performance of the gas turbine, a major inspection program is required. Thermal efficiency analysis is the parameters of success in major inspection activities. Thermal efficiency analysis is carried out by comparing data and operating parameters of gas turbine before and after the major inspection. The analysis aims to determine the actual efficiency of each component, and also the actual overall efficiency in the gas turbine. The study result is the actual thermal efficiency of a gas turbine after a major inspection has increased from 12.20% to 12.84% at a load of 6 MW, an increase from 15.76% to 16.77% at a load of 9 MW, and an increase of 18.59% to 20.16% at a load of 12 MW. Based on the actual performance comparison data with design data, it is known that the overall actual performance is still below the design performance, both heat efficiency, heat consumption and heat rate. This is caused by the operating lifetime
