“…If the injector nozzle pressure is higher than standard, replace the injector shim with a lower thickness value and vice versa [17]. There are several performance parameters of the Diesel Engine (Compression Ignition Engine), including Brake Power (BP), torque (T), Specific Fuel Consumption (SFC), Brake Thermal Efficiency (ὴB) and others [24,25,26].…”

The injector is one of the main components of a diesel engine fuel system. A typical fuel injector has two basic parts: the nozzle and the injector body. If either of these components is clogged or damaged, it will compromise the entire performance of the engine. Any injector problem can easily be fixed by cleaning, reconditioning, or replacement. If the engine is producing low power, replacing the injector nozzle with a new injector nozzle is necessary, so that engine performance reaches standard performance. However, replacing a new injector nozzle carries a huge maintenance cost. In this research, reconditioning or repairing the used injector nozzle to increase the fuel injection pressure in the engine is one solution that can be done to improve engine performance with low maintenance costs. The testing results found that brake power and brake thermal efficiency increase as fuel injection pressure increases, but specific fuel consumption decreases. For both the used injector and repaired injector, the minimum specific fuel consumption (SFC) does occur at the maximum brake power (BP) not generated. This means that the diesel engine never occurs in a condition of maximum power generated with minimum specific fuel consumption or vice versa.

“…However, pneumatic systems have a significant downside, namely, their non-linear behavior due to the compressibility of air, friction between the piston and cylinder, and discontinuous flow through control valves [6,7]. Additionally, modeling these systems dynamically is challenging because their air dynamics are often based on empirical assumptions [8]. Achieving precise positioning of pneumatic actuators is also challenging.…”

“…System identification (SI) differs from the theoretical approach by relying on observational analysis, rather than fundamental laws of nature, to determine its concepts. SI is a method that can be used to model systems and estimate unknown parameters, as well as to linearize systems to mitigate the limitations of mathematical models [8]. Moreover, this approach proves particularly suitable for complex systems or processes, especially within real-world, practical settings.…”

This study aims to improve the performance of a pneumatic positioning system by designing a control system based on Fuzzy Fractional Order Proportional Integral Derivative (Fuzzy FOPID) controllers. The pneumatic system’s mathematical model was obtained using a system identification approach, and the Fuzzy FOPID controller was optimized using a PSO algorithm to achieve a balance between performance and robustness. The control system’s performance was compared to that of a Fuzzy PID controller through real-time experimental results, which showed that the former provided better rapidity, stability, and precision. The proposed control system was applied to a pneumatically actuated ball and beam (PABB) system, where a Fuzzy FOPID controller was used for the inner loop and another Fuzzy FOPID controller was used for the outer loop. The results demonstrated that the intelligent pneumatic actuator, when coupled with a Fuzzy FOPID controller, can accurately and robustly control the positioning of the ball and beam system.

“…In the iterative approach, several strategies have been proposed, such as Artificial Neural Network [11] [12], iterative algorithm [13], genetics algorithm, ANFIS, Fuzzy Logic, evolution algorithm (EA) [14] [15], and iterative algorithm [16] [17]. The geometric approach offers a simpler calculation such as repetitive basic inverse kinematics of a two-link [18], the angular deflection of the upper platform concerning the lower platform [19], a non-iterative geometric approach for inverse kinematics [20], and a modified modal method [21] [22].…”

A solution based on inverse kinematics is required for the robot's end effector, also known as its tip, to reach a target. Current methods for solving the inverse kinematics solution for a hyper-redundant robot in three 3D are generally complex, difficult to visualize, and time-intensive. This requires the development of new algorithms for solving inverse kinematics in a quicker and more efficient manner. In this study, an axis manipulation using a geometrical approach is used. Initially, a general algorithm for a 2 m-link hyper-redundant robot in 3D is generated. The method employed a repetitive basic inverse kinematics solution of a two-link robot on virtual links. The virtual links are generated using a specific geometric proposition. Finally, the 3D solution is generated by rotating about the global z-axis. This method reduces the mathematical complexity required to solve the inverse kinematics solution for a 2-m-link robot. In addition, this method can manage variable link manipulators, thereby eliminating singularity. To demonstrate the effectiveness of the model, numerical simulations of hyper redundant models in 3D are presented. This new geometric approach is anticipated to enhance the performance of hyper-redundant robots, enabling them to be of greater assistance in fields such as medicine, the military, and search and rescue.
