Abstract

In recent years, there have been many studies on the widespread use of liquid fuels derived from biomass. A common emphasis in such studies is on fewer exhaust gas emissions and the expansion of renewable fuel production. Biodiesel is considered to be an important type of biomass fuel that is already produced commercially. But the production of biodiesel is laborious and comprises combination of several chemical processes. This study examines the effects of using oil used in biodiesel production with oxygen-rich chemicals on combustion (in-cylinder pressure (Cp), heat release rate (HRR), rate of pressure rise (RoPR), and cumulative heat release (CHR)), exhaust emission values, energy and exergy analysis. In this study, the effects of butyl di glycol use were also investigated and compared with commercially used ethanol and n-butanol. A transesterification method produced from canola oil the biodiesel used in the experiments. The experimental fuels were mixed volumetrically. For this purpose, experiments were carried out with canola biodiesel produced at 20% (D80B20) in diesel fuel and the results of the experiments were recorded. Under the same conditions, experiments were carried out by adding ethanol (D60C20E20), n-butanol (D60C20B20), butyl di glycol (D60C20G20) at a rate of 20% by volume to the canola oil added to the diesel fuel. The lowest values in terms of thermal and exergy efficiency were obtained in D60C20G20 fuel at all engine loads. Also, the highest entropy generation was calculated at all engine loads for this fuel blend.

Abstract

Compressed natural gas (CNG) is a popular alternative fuel because of its more environmentally friendly properties than fossil fuels , including applications in diesel engines. However, supplying too much compressed natural gas fuel causes poor engine performance and emissions due to a decrease in the air-fuel ratio on the dual-fuel engine. The addition of air using electric superchargers was done to return the air-fuel ratio to ideal conditions. Lambda value (λ) was variation under low load (1.52 to 2.71), medium load (1.18 to 2.17), and high load (0.94 to 2.17) on a CNG-diesel dual fuel engine. The addition of pure air in each load can increase combustion stability in certain lambda, which was indicated by an increase in thermal efficiency, heat release rate, and a decrease in ignition delay, combustion duration, hydrocarbon, and carbon monoxide emissions.

Abstract

Compressed Natural Gas (CNG) is an affordable fuel with a higher octane number. However, older CNG kits without electronic controls have the potential to supply more fuel when driving downhill due to the vacuum in the intake manifold. Therefore, this article presents a development of a CNG control system that accommodates road inclination angles to improve fuel efficiency. Machine learning is involved in this work to process engine speed, throttle valve position, and road slope angle. The control system is designed to ensure reduced fuel consumption when the vehicle is operating downhill. The results showed that the control system increases fuel consumption by 25.7% when driving downhill which an inclination of 5ᵒ. The AFR increased from 17.5 to 22 and the CNG flow rate decreased from 17.7 liters/min to 13.8 liters/min which is promising for applying to CNG vehicles.

Abstract

Sustainable transport is an important concept to reduce dependence on fossil fuels and to realize a cleaner and more sustainable future. This is achieved through the use of clean energy, low-emission vehicles, efficient use of resources, and transportation planning that considers the needs of the environment and society. Therefore, the use of clean and renewable energy sources, Mass Rapid Transit (MRT), and non-motorized mobility continue to be promoted to support a sustainable transportation system. However, there are several challenges that must be overcome to achieve a truly sustainable transport system, including the costs of switching to clean energy and low-emission vehicles, the lack of infrastructure to support sustainable transport, and the need for greater public awareness and education. about the benefits of sustainable transportation.

Abstract

A fuel cell power generation system is a renewable energy system that works based on electrochemical processes and produces a direct electric current (DC). Specifically, a Proton Exchange Membrane (PEM) Fuel Cell can operate at low temperatures and produce an efficiency of around 40-60%. In this study, the performance test of the PEM Fuel Cell for power generation was carried out by supplying hydrogen gas using hydrogen from the electrolysis of the hydrogen generator with a variation of KOH catalyst solution with a concentration of 0.5 M; 1.0 M; 1.5 M; 2 M and using Ultra High Purity (UHP) hydrogen with various flow rates of 250 mL/min, 300 mL/min, 350 mL/min, 400 mL/min, 450 mL/min, and 500 mL/min. The test results showed that the output power of hydrogen produced by the electrolysis process was 10.8 W at a concentration of 1 M solutions at an input current of 20 A. The greater the concentration of the catalyst solution, the smaller the electrical power required for the electrolysis process. However, the hydrogen power supply produced by the hydrogen generator was not optimal, so it did not meet the needs of the PEM Fuel Cell. As a result, the PEM Fuel Cell could not work. Meanwhile, testing with UHP hydrogen produced the highest electrical power of 31.588 W at a flow rate of 450 mL/min with a load of 20 W. It indicates that the PEM Fuel Cell is optimal at the output power value with an efficiency of 69.80%.

Abstract

This article presents Ansys simulations and experimental testing to determine how TBC affects engine performance and emissions. In this work, two distinct thermal barrier coatings have been identified, and the same coating materials were subsequently sprayed onto the pistons of an internal combustion engine. Transient thermal analysis reveals that TBC-1 and TBC-2 coatings reduce surface temperature distributions by 35% and 18%, respectively, and that these engines improve Brake Thermal Efficiency (BTE) by 8.71% and 7.62%, respectively, compared to non-coated engines operating under full load. TBC-1 and TBC-2 coated engines are found to have Brake-Specific Fuel Consumption (BSFC) reductions of 27.13% and 18.81%, respectively. Complete combustion reduces emissions of CO and HC, as the heat balance sheet indicates because the conversion of energy and mechanical work are enhanced by 3.56 percentage points and 2.0 percentage points, respectively.

Abstract

This study aims to determine the reliability of applying a thermal management system in conjunction with Internet of Things in solar electric cars. In conventional electric cars or those whose driving energy source comes from gasoline fuel; the applied thermal management system is mainly used as a coolant for the internal combustion engine. However, for electric cars the thermal management system may be used for the main components such as controllers that convert solar module energy into electricity and batteries. Results from tests utilizing six DC fans for air cooling of the thermal management system yield two variations of battery charging conditions from the solar modules, namely variations of 25 and 400 turns of the trimmer constant current step-up charger. Test results from the proposed thermal management system show that the highest step-up charger temperature is 35.75 °C with voltage of 57.64 V for the variation of 25 laps. The test results on the battery voltage and temperature show that the highest battery temperature reaches 31.75 °C with voltage of 57.3 V at the variation of 25 rounds.

Abstract

Alternative fuels were developed by blending crude coconut oil and bio-carbon nanoparticles. Bio-carbon, derived from sago waste via pyrolysis and ground using a ball mill, underwent FTIR testing to assess its energy absorption capabilities. SEM analysis was conducted to examine the surface morphology of bio-catalyst with and without crude coconut oil. The findings indicate that incorporating bio-catalyst can enhance mechanical properties, facilitating rapid heat absorption, as evidenced by reduced flashpoint and viscosity. In addition, the results show an increase in fuel mass, broadening of molecular contacts, increased reactivity, and increased heat absorption for easier ignition. This phenomenon indicates that bio-carbon of sago waste have great potential for biofuel use as a homogeneous combustion catalyst.

Abstract

In the global pursuit of transportation decarbonization, this essay asserts that heavy-duty fuel cell electric vehicle (FCEV) technology represents a more compelling path forward than light-duty FCEVs. The inherent advantages of fuel cells, such as extended range, rapid refueling, and sustained performance, make them well-suited for demanding applications like trucking and public transit. Heavy-duty FCEVs offer significant potential for emissions reduction, integration with existing infrastructure, and economies of scale through commercial fleet adoption. While the upfront investment is substantial, the essay examines how operational benefits can gradually offset costs, emphasizing the importance of heavy-duty FCEVs in sustainable transportation solutions.
