Abstract

This study investigates and compares the cost of generating electricity from petrol and liquified petroleum gas (LPG) gas using a 2.5 kVA, 50Hz Elepaq generator. It also develops mathematical models that can be used to predict important parameters of the generator The generator is connected with a multi-fuel carburetor in the experimental setup, allowing both fuel sources to be fed alternatively. The electric bulbs of different ratings were connected and varied as load. The generator was first run using petrol. The time used to exhaust half litres of petrol was recorded. It was then run with LPG for a period equal to the time of run on petrol, taking note of the mass of LPG consumed. A cost comparison was carried out and mathematical models were developed for both fuels usage using MATLAB “polyfit” command. The results show that with less or equal 1350W connection of purely resistive load. It is more economical to run the generator using LPG. However, at any load beyond 1350 W, it is economical to run the generator using petrol. The two models developed best fit the experimental results obtained with a correlation of 0.9869 and 0.9962.

Abstract

This study investigates the level of experienced motion sickness when performing reading while being driven in fully automated driving under three different conditions. One condition was without any intervention while the other two conditions were with the visual (VPIS) and haptic (HPIS) peripheral information system. Both systems provided the upcoming navigational information in the lateral direction three seconds before the turning/cornering was done. It was hypothesized that with the peripheral information systems, the experienced motion sickness would be reduced compared to the condition where a peripheral information system was not present. Eighteen participants with severe motion sickness susceptibility were carefully chosen to undergo the conditions using an instrumented vehicle with the Wizard-of-Oz approach. The participants were required to read from a tablet during the whole 15-minutes of automated driving. Results from the heart rate variability (beats per minute, root means square of successive differences, and high-frequency component) indicated no statistically significant changes (p < 0.05) in motion sickness found with the presence of HPIS and VPIS when performing reading when being driven in automated mode. However, results from this study were mixed and inconclusive, but overall findings indicated mild motion sickness was found in both VPIS and HPIS conditions.

Abstract

Circularity is not a new concept. Activities such as reuse or recycling have been around for centuries. Today, an urgent solution to tackle the increasing harmful emissions resulting in severe climate changes is being proposed and investigated. This is because a link between industry and the environment is critically important for business. A more sustainable socio-technical system is therefore urgently needed. There has been a rapid growth of academic articles on the circular economy. The circular economy concept has been considered a solution to many of today’s challenges, including resource scarcity and waste generation.

Abstract

In comparison to ethanol biofuel, butanol is considerably less corrosive, permitting the utilization of existing infrastructures used to ship gasoline or diesel for its distribution. Less corrosive also means that butanol can be utilized with no engine alteration. If butanol is mixed with water, it is less likely to split from the main fuel, thus facilitating the storage and distribution of blended fuels. Butanol also comprises a comparable energy content to petrol fuel, with 25% more energy density/liter as opposed to ethanol. All these excellent qualities have led to higher engine performance, enabling the vehicles to achieve higher mileage using butanol with no significant issue. Several challenges and future research directions are discussed and in the last section of this review article, we emphasize the importance of an optical engine to diagnose engine combustion in more detail. The consequence of using butanol on spark ignition engine on cold start and knock phenomena are also worth investigating. Results on the spray, the pressure inside the cylinder, rate of heat release, and detonation are thus required.

Abstract

Applying magnetic fields to improve the arrangement of hydrocarbon molecules in fuel lines have been continuously studied in recent decades. However, scientific reports regarding the application of a magnetic field integrated with a gasoline vaporizer tube (GVT) on engine performance have not been widely discussed. Therefore, this article presents an investigation of the application of GVT with magnetic field on a single cylinder gasoline engine with three different fuel qualities, including RON88, RON92, and RON98. Torque, power, emissions and fuel consumption have been tested for scientific opinion. The results of our present investigation seem to confirm the claims of GVT inventors, where GVT increases engine torque and power, reduces CO and HC content in exhaust gases, and reduces fuel consumption. However, without considering the supply of gasoline and air from the GVT to the engine is an unfair analysis. In fact, although the established theories reveal the benefits of applying a magnetic field to the fuel line, in this case, only a small part of the fuel is induced by the magnetic field, outside the main line from the tank to the injectors. Finally, the results of this investigation provide new insights for potential users of GVT, which is currently commercially available.

Abstract

Quenching is a swift way of returning metal back to ambient temperature in order to acquire a certain property. Although it is often used to enhance the hardness of metals and their micro-structure, it equally causes a serious variation in the mechanical and physical properties of the metals. This research focuses on quenching media's effect on the microstructure and mechanical properties of a 150mm x 80mm x 8mm welded mild steel plate through microscopic examination, metallography mounting, surface grinding, and surface polishing. Microstructural analysis with hardness and impact test was carried out on the steel plate using water, air, and oil as the quenching media. The results of the test show the Vickers Pyramid Number (HV) for water, oil, and air to be 284.2, 270.9, and 262.2 HV for the base metal, heat affected zone (HAZ), and weld metal (WM), respectively. The amount of energy absorbed by the three specimens during fracture is 23.12, 25.27, and 26.83 J, respectively. The test further indicates that the water-quenched media exhibited mostly martensitic structures and held back austenite with many structures of cementite while the oil and air media exhibited martensite phase and refined grains structures individually. It is therefore concluded that air is more suitable to cool the weld metal for damping applications in engineering.

Abstract

The ever-increasing demand for independent mobility has escalated vehicle production across the globe. However, very less focus is given to drivers who are physically impaired or have a driving disability. Thus, the primary purpose of this research is to design a low-cost infrared sensor-based remote-operated driving system for people with lower body disabilities and leg impairment. The presented design is based on an Arduino UNO microcontroller that is programmed and coupled to an infrared sensor to press and release the brake and acceleration pedals, which can be hand-controlled by the disabled driver. Two TB6600 microstepping drivers and NEMA-23 stepper motors have been externally powered using a Volta 12V lead-acid maintenance-free battery at 2.5 amperes with a peak current of 2.7A, and 200 steps/rev. for maximum output torque. An LED and alarm have been placed on the dashboard for an emergency alert or system failure. Additionally, brake and acceleration pedals have been tied to a monofilament cord, which further connects the motor shafts to assist pedalling operation and allows the driver to control the brake and acceleration pedals through an IR remote. The findings comprise two models: theoretical and actual. Results show that theoretical braking time is around 0.7s while actual braking time is found as 0.6s, which shows a good agreement.

Abstract

Conventional gasoline engines suffer from low performance and NOx emissions. Controlled auto-ignition (CAI), sometimes referred to as homogeneous charge compression ignition (HCCI), is a promising concept to solve such problems. CAI has the potential to improve spark ignition (SI) engine fuel economy while at the same time solving the trade-off of NOx-soot emissions found in compression ignition (CI) engines. The CAI engine can reach a fuel economy comparable to that of a conventional diesel engine with ultra-low NOx and negligible soot emissions. However, controlling auto-ignition remains the biggest difficulty that hinders the implementation of CAI as a commercial engine. Research towards a cleaner and more efficient engine is driven by the progressively stringent emission regulation imposed worldwide. Therefore, the CAI was developed to meet the emissions target while maintaining engine performance. CAI works on the principle of lean mixture and auto-ignition. To obtain CAI combustion, the temperatures in the cylinder must be sufficient to initiate auto-ignition. Without the use of a spark plug or injector, the CAI suffers from a direct control mechanism to start the combustion. The most practical approach to controlling the initiation of auto-ignition in CAI is diluting the intake charge by either trapping the residual gas or recirculating the exhaust gas. Both approaches enable the engine to achieve CAI combustion without requiring significant modifications to control the onset of CAI combustion phase.

Abstract

Air-conditioning and refrigeration systems are electrical appliances that use a huge amount of energy and contribute indirectly to global warming. Also, R410A which was initially developed as a substitute for ozone-depleting refrigerants in the air-conditioning systems has been phase-out due to its high global warming potential (GWP) and the resulting harmful effect on the climate. In addition to the issue of refrigerant high GWP, energy consumption is a significant issue. The energy efficiency of new refrigerants must then be considered in the search for alternative refrigerants to ensure that they do not lead to an increase in greenhouse gas generation at the power source. Therefore, this paper investigates the energy and cooling performance of four new multi-components and ecologically friendly refrigerant blends that contained carbon dioxide and hydrofluoroolefins in their compositions as substitutes for R410A in air-conditioning systems. Relevant thermodynamic equations and REFPROP software were employed for the computational analysis. The results indicated that the new blends (R445A, R455A, R470B and R470A) exhibited a desirable low compression ratio and high heat transfer for cooling applications. The blends also exhibited low compressor energy input and low specific cooling energy. R455A has an average coefficient of performance (COP) of 24.6% above that of the reference refrigerant (R410A). The cooling capacity per unit volume for R470B, R455A and R470A across a temperature range of 253 to 293 K are higher by 1.3, 6.0, and 12.6%, respectively than that of R410A. Generally, among all the four new substitute blends, the overall assessment revealed R455A as the best replacement for R410A in air-conditioning systems due to its superior performance in terms of its low compression ratio, compressor energy and specific cooling energy. R455A also has the highest COP and relatively high cooling capacity per unit volume.

Abstract

As of today, only a few people know about carbon black. Their knowledge and understanding are also limited to the fact that carbon is charcoal from coconut shells or black activated carbon. In addition, some people only know carbon as carbon copy and ink material. On the other hand, there is another type of carbon that comes from oil content and can be used for various industrial purposes. This carbon is produced and used with advanced and modern technology, which is called carbon black. Currently, by looking at the market signal, carbon black has become a very profitable commodity. Carbon black industries develop systems and technologies to produce the best quality with minimized environmental effects. In fact, because of the promising price and high market demand, carbon black factories invest in advanced production equipment. In its development, through continuous research and by utilizing advances in industrial technology, currently, carbon black can be added to various materials to improve the physical, electrical, or optical properties of the material.
