ANALISA KERUSAKAN WEIGHT COMP BALANCER PADA SEPEDA MOTOR HONDA CB150R NEW 2019 Di PT.XX

The Weight Comp Balancer functions as a shaft as well as a balancing weight for the Balancer Assy component.From the data obtained in the form of consumer complaints about the New 2019 CB150R motorcycle, some consumers of the New 2019 CB150R motorbike often complain about abnormal engine vibrations, causing engine performance to decline and cause rough sound in engine sound, From the results of the hardness test on the Shaft Weight Comp Balancer, the average results are 512 HL, 231 HB, 236 HV and the results of the hardness test on the Pen Weight Comp Balancer are obtained from an average of 504 HL, 223 HB, 228 HV, From the results of the identification of the cause of the Weight Comp Balancer damage, it can be concluded that the bending of the Shaft Weight Comp Balancer for the New 2019 CB150R Motorcycle engine is caused by misalignment due to the inaccurate selection of the Spring Mount design on the Balancer Assy

A Study to Investigate the Effect of Valve Mechanisms on Exhaust Residual Gas and Effective Release Energy of a Motorcycle Engine

The purpose of this study was to investigate the effect of valve mechanisms on the exhaust residual gas (ERG) and effective release energy (ERE) of a motorcycle engine. Here, a simulation model and the estimation a new valve mechanism design is presented. An AVL-Boost simulation model and an experiment system were established. The classical spline approximation method was used to design a new cam profile for various valve lifts. The simulation model was used to estimate the effect of the new valve mechanism designs on engine performance. A new camshaft was produced based on the research data. The results show that the engine obtained a maximum engine brake torque of 21.53 Nm at 7000 rpm, which is an increase of 3.2% compared to the engine using the original valve mechanism. In addition, the residual gas was improved, the maximum engine effective release energy was 0.83 kJ, the maximum engine power was 18.1 kW, representing an improvement of 7.2%, and the air mass flow was improved by 4.97%.

Sistem Pemantauan Kelayakan Pelumas Oli pada Kendaraan Sepeda Motor dengan Memanfaatkan Teknologi Internet of Things

AbstrakSepeda motor memerlukan perawatan yang oprtimal terutama are mesin yaitu dengan melakukan pergantian oli yang berfungsi sebagai pelumas mesin. Oli mesin membantu menghindari gesekan langsung antara logam di mesin, sehingga mengurangi tingkat kerusakan mesin. Penelitian ini akan dirancang suatu sistem pemantauan pergantian oli sepeda motor berdasarkan jarak tempuh dan waktu pemakaian oli yang berbasis IoT. Dimana penggunaan sepeda motor digunakan untuk menyimulasikan perputaran roda, sensor proximity sebagai pendeteksi putaran roda, serta mikrokontroller ESP32 sebagai pengendali utama, buzzer untuk memperingati pengguna, relay digunakan untuk mematikan mesin sepeda motor, dan GSM sebagai pengirim data. Pada penelitian ini diperoleh hasil yang diharapkan, ketika jarak tempuh mencapai jarak 2000km maka sistem akan memperingati pengguna sepeda motor dan ketika pengguna mengabaikan peringatan tersebut dan jarak mencapai 2100km maka sistem mematikan kelistrikan sepeda motor. Namun jika jarak tidak tercapai tetapi pemakaian oli telah mencapai 60 hari maka sistem memperingati pengguna sepeda motor.Kata kunci: Gsm, Mikrokontroler, Otomasi, Sensor, Sepeda MotorAbstractMotorcycles require optimal maintenance, especially the engine, namely by changing the oil, which functions as an engine lubricant. Engine oil helps avoid direct friction between the metals in the engine, thereby reducing engine damage. This research will design a motorcycle oil change monitoring system based on mileage and time of oil usage based on IoT. Where the use of a motorcycle is used to simulate wheel rotation, a proximity sensor is used to detect wheel rotation, as well as the ESP32 microcontroller as the main controller, a buzzer to warn the user, a relay is used to turn off the motorcycle engine, and GSM as a data sender. In this study, the expected results are obtained, where when the distance reaches a distance of 2000km, the system will warn the motorcycle user and when the user ignores the warning and the distance reaches 2100km, the system will turn off the motorcycle electricity. However, if the distance is not reached but the oil consumption has reached 60 days, the system will warn motorcycle users.Keywords: Gsm, Microcontroller, Automation, Sensors, Motorcyle.

Perancangan Penyalaan Engine Sepeda Motor Berbasis Arduino Melalui Bluetooth Android

Motorcycle ignition which also functions as a motorcycle safety needs to be designed and made as safe as possible to avoid the loss of the vehicle from theft cases. This equipment is designed to turn on/off and search for motorcycles using a remote from a smartphone with an android operating system via a bluetooth network. The bluetooth input is controlled using the Arduino Uno microcontroller. From the test results, it is found that the maximum distance that can be achieved between Android and Bluetooth to operate a motorcycle engine is about 10 meters. This system also makes our motorcycle engine ignition a smart ignition.

THE EFFECT OF BRASS (Cu-Zn) CATALYTIC CONVERTER ENGINE PERFORMANCE

Installing a catalytic converter in the exhaust is a typical method of reducing engine exhaust emissions. Catalytic converters have been shown to lower exhaust pollutants while enhancing engine performance. The influence of the number of brass catalyst plates (Cu-Zn) on the Performance of the commercial Yamaha Jupiter MX motorcycle engine manufactured in 2007 was investigated in this study. The catalyst is installed in the motorbike exhaust, with the number of catalyst plates varying between 5 and 8, and a conventional uncatalyzed exhaust serving as a comparison. Torque, power, specific fuel consumption, and thermal efficiency are among the performance factors that will be considered. A prony brake dynamometer was used to conduct torque and power measurements. The results indicate that exhaust with eight catalyst plates can improve engine performance more than an exhaust with five catalyst plates. Furthermore, exhausts equipped with eight catalyst plates can boost engine efficiency by an average of 17.65%. Thus, increasing the number of catalyst brass plates improves the machine's efficiency.
