Abstract: Recently MRF d er -which has a significant controllable d ing force - used frequently in many active and semi-active suspension systems. However, MRF d er needs controller to estimate the desired force to dissipate the occurred vibration instantaneously. PID controller is one of the effective feedback controllers which shows robustness and simplicity in control MRF d ers, but still the parameters of the PID controller under study to find out the optimum values. This study focused on the vibration control using Magneto-rheological (MR) d er on a FSAE quarter car suspension test rig to study and obtain the optimum running condition. The test rig was designed, modified and then tested using a P-controller integrated with MR d er, unbalance mass used as disturbance and analyzed using LABVIEW software in time and frequency domains. The natural frequency obtained was 2.2 Hz were similar to the actual FSAE car natural frequency. Based on the acceleration against time graph with different proportional gain value the optimal value for proportional gain, Kp was 1. Hence, the experiment work could be used as the initial stage to study and develop a robust controller to suppress vibration on a car.

Abstract: Previous works revealed that cross-corrugated absorber plate design and jet impingement on a flat absorber plate resulted in a significant increase in the performance of a solar air heater (SAH). Involving these two designs into one continuous design to improve the SAH performance remains absent in the literature. This study aimed to evaluate the achieved enhancement on performance parameters of a SAH with jet impingement on a corrugated absorber plate. An energy balance model was developed to compare the performance parameters of the proposed SAH with the other two SAHs. At a clear sky day and a mass flow rate of 0.04 kg/s, the hourly results revealed that the max fluid outlet temperatures for the proposed SAH, jet-to-flat plate SAH, and cross-corrugated plate SAH are 321, 317, and 313 K, respectively the max absorber plate temperatures are 323.5, 326.5, and 328 K, respectively the maximum temperature differences between the absorber plate and fluid outlet are ~3, 9, and 15 K, respectively the max efficiencies are 65.7, 64.8, and 60%, respectively. Statistical t -test results confirmed significant differences between the mean efficiency of the proposed SAH and SAH with jet-to-flat plate. Hence, the proposed design is considered superior in improving the performance parameters of SAH compared to other designs.

Abstract: Nowadays, the concern of vehicle manufacturers towards improving engine performance, reducing fuel consumption and exhaust emissions that can cause the pollution of the atmosphere, concerns of strict emission pollution control regulations. Intercooler heat exchanger devices are used for engine charge air temperature improving for engine performance and emissions reduction. This paper introduces a new add-on technology of intercooler heat exchanger- (IHE) developed for utilizing in intake charge air density enhancement in engine combustion for better performance. Presenting a challenge in contributing a framework process for geometry designing development procedure for accurate and reliable scale design size of an air-vapour gas shell-and-tube IHE type, used refrigerant coolant medium. The process presents effective IHE in design time consumption, accurate in scale with higher performance and reliability operation in all environment weather due to reversibility system. A selected design geometry of 60 bunches of tubes with 7.53 mm inner diameter and 150 mm long placed. Effectiveness and design parameter geometry calculation are conditions of the IHE dependent relations of the shell size to tube length in condition of engine space availability control. Pressure drop and cooling capacity of IHE configuration design are proportional to the availability of design space or pressure drop control by the engine. Numerical and simulation results expressed a significant ability of IHE of 2–13 kW cooling load and process applicability for qualified design geometry configuration for selected IHE type. The developments present significant geometry flexibility design with the ability of cooling load or heating effect if reversible system, which offered multipurpose use in widely all vehicle types.

Abstract: The adoption of biorenewable alternative fuel resources from biofuels (ethanol or biodiesel) has produced promising solutions to reduce some toxic greenhouse gas (GHG) emissions from gas turbine engines (GTEs). Despite the reduced hydrocarbon associated with adopting alternative bio-renewable fuel resources, GTE operations still emit toxic gases due to inefficient engine performance. In this study, we assess the impact of the integration of plasma combustion technology on a micro-GTE using biodiesel fuel from animal fat with the aim of addressing performance, fuel consumption, and GHG emission reduction limitations. Laboratory design, fabrication, assembly, testing, and results evaluation were conducted at Kuwait’s Public Authority for Applied Education and Training. The result indicates the lowest toxic emissions of sulfur, nitrogen oxide (NO), NO2, and CO were from the biodiesel blended fuels. The improved thermal efficiency of GTE biodiesel due to the volume of hydrogen plasma injected improves the engine’s overall combustion efficiency. Hence, this increases the compressor inlet and outlet firing temperature by 13.3 °C and 6.1 °C, respectively. The Plasma technology produced a thrust increment of 0.2 kgf for the highest loading condition, which significantly impacted horsepower and GTE engine efficiency and reduced the cost of fuel consumption.
