The use of diesel engines for vehicle applications has expanded for decades. However, it produces black smoke in the form of particulate matter contains fine and invisible particles during operation. The popular method for measuring the smoke opacity is by using a smoke meter for its simplicity and less costly. Fuel injection pressure is one of the parameters that affect the emission significantly, and the proper nozzle adjustment can reduce the density of exhaust gases and improve the engine performance. The purpose of this study is to determine the optimum fuel spray pressure that produces the lowest opacity value and analyse the effect of fuel spray pressure on the opacity value at a different engine speed. The present experiment uses the Hyundai D4BB engine, and the pressure variations were implemented on the injector nozzle at 125, 130, and 135 kg/cm2. The engine was also tested with various engine idle speed, i.e., 1000, 1500, 2000, and 2500 rpm. It has been found that the optimum distance of fuel spraying is 147.679 mm with injector nozzle pressure 130 kg/cm2, and the value of opacity is 9.51%.

There are many racing air filter products on the market with air filter fold gap of 45 microns. However, there has been no research proves that an air filter with 45 microns’ fold gap can increase the performance of a car engine. Based on this, the author is interested in conducting an experimental test analysis of the car engine air filter by modifying the factory standard air filter which has fold gap of 25 microns into an air filter that has fold gap of 45 microns. This study aims to prove whether a 45-micron air filter can increase the performance of a car engine in the form of torque, power, fuel consumption, and mechanical efficiency. The study is conducted by using dynamometer. Analysis of research data uses descriptive statistics with data presentation in the form of tables and graphs. The results of this study indicates that the effect of a 45-micron air filter on a car engine performance is proven to improve car engine performance compared to factory standard air filters with details: torque in car engine increases by 3.05%, power in car engine increases by 1.78%, the specific fuel consumption of the car engine is 1% more efficient, and the mechanical efficiency of the car engine is increased by 0.02%. Based on the research that has been done, it is necessary to do further research regarding the effect of the 45 micron racing air filter on the service life of the piston and valve in the car engine.

Engine failure is difficult to predict, especially related to the age of engine components. Analysis of engine failure can be done based on the oil seen from the trend of wear rates, predicting the possibility of components that are damaged in the engine. The method used is a combination of oil analysis in order to determine the component that is damaged and determine the age of the component based on the trend of the element value with the Component Meter Unit (CMU) and implement the Failure Mode and Effect Analysis ( FMEA) method to support the analysis by looking at the value of the Risk Priority Number (RPN). The result of this analysis is that there is slightly above normal wear on the Cu and Pb elements, where in the last sample the values for Cu 3 and Pb 5 are Particle Per Meter (PPM). CMU predictions are also generated before passing the threshold of the wear limit based on the value of each element. Fe at 17931 hours, Cu at 25963 hours, Pb at 14417 hours and Al at 16927 hours. Wear is indicated from the FMEA analysis, there are 3 with the highest RPN, namely cutting filter result with RPN 280, noise with RPN 175 and scratch with RPN 160. From these Cu and Pb elements it can be determined which components are the source of damage, namely rocker arm bushings, wrist pin bushings, governor drive and bushings, timing gear thrust bearings, turbocharger bearings, camshaft lifter roller pins, air compressor bearings, rear cluster gear bearings and main and rod bearings. From this research, new research data can be developed, namely if there are additional parameters such as oil viscosity value.

Electro-deposition process to develop surface layer on the substrate material in Catalytic converter (CATCO) become interesting area due to that process was purposed to improve the physical properties of substrate material. Currently, precious metals such as Platinum (Pt), Palladium (Pd), and Rodium (Rd) were used due to excellent oxidation resistant but it limited and easily oxidized. Therefore, Nickel Oxide (NiO) catalyst used as electro-deposition material. NiO electro-deposition technique that called by EL was conducted by using NiO as cathode and FeCrAl as substrate and -Al2O3 as washcoat material. This technique was performed by variation times of 15, 30, 45, 60 and 75 minutes, current density of 8 A/dm2. The results shows that Coating layer of NiO and -Al2O3 has been developed on surface of FeCrAl substrate. The coating layer was increase the surface roughness which showed by surface morphology data that coated FeCrAl substrate has uneven surface and some particles has been embedded on that surface. The composition of raw material was consists of Fe for 74.13wt%, Cr of 20.25 wt% and Al of 5.62 wt%. Meanwhile, for composition of EL samples was 52.56- 63.54wt% for Fe element, Al for 3.56-11.89 wt%, Cr for 14.97-18.56 wt%, O for 2.47-11.78 wt%, C for 8.33-11.85 wt%, Na for 0.11-0.48 wt% and Ni for 0.17- 1.58 wt%. Higher elements of the EL samples potential to improve the thermal stability at high temperature due to CATCO operate at high temperature of 600-8500C and in extreme condition.

Congestion at toll roads has become a pervasive issue in contemporary times, predominantly manifesting at toll booths during the payment process. A noteworthy contributor to this congestion has been identified as the sluggish operational speed of boom gates. In response to this challenge, a modification strategy was implemented to enhance the operational efficiency of existing boom gates. The primary modification involved substituting the conventional electric motor with a more advanced Brushless DC (BLDC) motor boasting a power rating of 660 watts. Additionally, an innovative augmentation integrated a motorcycle disk brake system into the boom gate mechanism. Replacing the original electric motor's internal brake system with the disk brake system aimed to optimize the overall performance of the boom gate. The integration of the motorcycle disk brake system was further complemented by incorporating the push braking system (knoken braking system), serving as the actuator instead of the traditional motorcycle lever handle. This strategic substitution was instrumental in activating the disk brake function at the boom gate. During peak rush hours, the modified boom gate underwent rigorous testing at both the Ciawi and Kelapa Gading toll gates. Results from the trial activities unveiled a remarkable improvement in the boom gate's operational speed. Specifically, the opening speed demonstrated an impressive surge of 51 percent, catapulting from 548 ms to 265 ms. Similarly, the closing speed exhibited a commendable enhancement of 44 percent, elevating from 602 ms to 332 ms. Furthermore, the boom gate cycle per hour experienced a notable escalation, increasing by 25 percent from 356 to 449 cars per hour. These findings underscore the efficacy of the implemented modifications in ameliorating congestion issues at toll booths.
