Car Accidents

Based on data from the Indonesian Traffic Corps by September 2019, the number of car accidents was dominated by rear-hit crashes with 6,966 accidents. Most of these accidents occurred during car convoys. It needs a car-to-car communication to increase driver awareness. One of the technologies that can be applied is Visible Light Communication (VLC) and infrared communication. The transmitted data are the vehicle speed data, throttle position, and brake stepping indicator. The data are obtained by reading the Engine Control Unit (ECU) in the car. The data are packaged from the three data and sent to other cars at day and night using VLC and infrared communication. The experimental results show that in a communication system that uses VLC, data can be exchanged between cars during the day up to 2 meters and at night up to 11 meters. Otherwise, in infrared communication, vehicles can communicate during the day up to 2 meters and at night up to 0.7 meter. The test was also carried out with some conditions such as rain, smoke, passers, and other vehicle lights.

Insertion Tool

In order to ensure that every portion of the emission control software in a vehicle works, all fault conditions must be tested. Simply simulating faults in the software of the engine controller and reporting it to the OBD II scanner is inadequate; the fault condition must be injected externally to the Engine Control Unit (ECU). In the case of hard-to-reproduce mechanical failures, this is a challenging task. This paper discusses the development of a system capable of emulating various faults that a fuel injector can have while operating as part of a complete working vehicle. For the ECU to operate properly, all fuel injectors must be present in the vehicle, be fully functional, and must represent an accurate electrical load to the ECU. Then, the induced faults must be seamlessly inserted into the running system in less than 10μs and removed before the subsequent injection event. This was accomplished with a variety of COTS hardware, a simple custom circuit, and the use of a large, flexible FPGA platform.

<p>Mesin yang berbasis <em>Electronic Fuel Injection</em> (EFI) banyak digunakan karena menghasilkan performa yang tinggi dengan konsumsi bahan bakar yang sedikit dan gas emisi buang rendah. Namun ketika kendaraan berbasis EFI sudah digunakan lebih dari 5 tahun biasanya akan mengalami penurunan kinerja motor bersin yang berpengaruh pada performa ataupun kecepatan kendaraan tersebut. Oleh karena itu harus dilakukan servis <em>tuning</em>untuk meningkatkan kinerja motor pembakaran dalam dengan cara menyetting (<em>Engine Control Unit</em>) ECU dari mobil tersebut agar menormalkan atau memperbaiki daya yang dihasilkan. Penelitian ini melakukan program remapping ECU dengan menggunakan software <em>BitEdit</em> yang diaplikasikan pada mesin I-VTEC<em>type</em> honda jazz. Berdasarkan data penelitian, setelah dilakukan <em>remapping </em>pada spesifikasi dasar terdapat peningkatan jarak tempuh kendaraan, efisiensi kendaraan, daya, dan torsi. Hasil pengujian daya juga menunjukkan peningkatan setelah dilakukan <em>remapping </em>yaitu dengan selisih daya terbesar mencapai 10.21 kW. Selain itu hasil pengujian torsi menunjukkan terdapat peningkatan torsi yaitu rata-rata sebesar 5.7 N.m.</p>

Modeling Methodology

This work is an extension of a novel physics-based ignition delay modeling methodology previously developed by the authors to predict physical and chemical ignition delays of multiple injections during steady operations in diesel engines. The modeling methodology is refined in this work to consider the influence of additional operating parameters such as volumetric efficiency, exhaust temperature and pressure on the ignition delay of multiple injections. Computational fluid dynamics predictions on two different engines indicated that the main spray encounters local temperatures about 60 K above average temperatures for about 1 mg of pilot. Hence, the modeling methodology was further refined to include this effect by considering the air mass trapped in pilot spray, computed based on the spray penetration and cone angle and tuned using results of the computational fluid dynamics studies. Comparisons of the ignition delay predictions with the stock boost temperature sensor and a specially incorporated, transient-capable fine wire thermocouple indicated that the measurements with stock sensor could be satisfactorily used for transients. Cycle-by-cycle changes in ignition delay could be predicted accurately when transients were imposed in boost pressure, rail pressure and main injection quantity in a turbocharged intercooled diesel engine controlled with an open engine control unit. Further validations were done even under a transient cycle when the engine was controlled by its stock engine control unit. The same tuning constants could be used for the prediction of the ignition delay under transients on another naturally aspirated engine. This indicates the suitability of the model for application in different engines. Finally, the model was incorporated within an open engine controller, and cycle-by-cycle prediction of ignition delays of the pilot and main injections were done in real time. It was possible to compute the ignition delays in less than 2 ms within engine control unit using the already available sensor inputs within an error band of ±60 µs.
