In this study, a real-time engine model and a test bench were developed to verify the performance of the EECU (electronic engine control unit) of a turbofan engine. The target engine is a DGEN 380 developed by the Price Induction company. The functional verification of the test bench was carried out using the developed test bench. An interface and interworking test between the test bench and the developed EECU was carried out. After establishing the verification test environments, the startup phase control logic of the developed EECU was verified using the real-time engine model which modeled the startup phase test data with SIMULINK. Finally, it was confirmed that the developed EECU can be used as a real-time engine model for the starting section of performance verification.

Berkembangnya teknologi membuat mesin kendaraan sekarang menggunakan sistem injeksi yang dilengkapi dengan berbagai komponen dan sensor untuk mendukung proses pembakaran di ruang mesin. Salah satunya yaitu TPS (Throttle Position Sensor). Sensor TP berfungsi untuk mendeteksi adanya perubahan posisi pada throttle gas. Adanya kerusakan pada sensor TP dapat mempengaruhi performa dari kendaraan. Umumnya pengecekan sensor TP dilakukan menggunakan multimeter yang tentunya sulit untuk dilakukan, karena posisi dari sensor TP yang sulit dijangkau. Maka dari itu dibutuhkan alat yang mampu digunakan untuk mengecek kondisi sensor TP secara efisien. TPS Checker merupakan alat yang digunakan untuk mengecek kondisi sensor TP melalui pengukuran tegangan pada input dan output sensor TP serta hambatannya sesuai dengan kondisi bukaan throttle gas. Hasil pengukuran didapat dari rumus pembagi tegangan (voltage divider). Alat TPS checker dibuat dengan menggunakan microcontroller ESP32 yang dapat dihubungkan dengan smartphone untuk menampilkan hasil pengukuran secara real-time melalui aplikasi Blynk serta dilengkapi fitur reset untuk menghapus data kerusakan yang sudah terdeteksi dan tersimpan di Engine Control Unit (ECU). TPS Checker dapat digunakan untuk mengukur sensor TP pada seluruh kendaraan injeksi, namun penulis melakukan pengujian TPS Checker menggunakan sepeda motor Honda Revo PGM-FI. Setiap tipe kendaraan memiliki standar pengukuran yang berbeda-beda. Standar pengukuran pada motor Honda Revo PGM-FI yaitu tegangan sensor TP sebesar 4,75V – 5,25V dan hambatan berada pada rentang 0 – 5K Ohm. Dari hasil pengujian TPS Checker dapat disimpulkan bahwa alat ini mampu digunakan untuk melakukan pengukuran pada sensor TP serta menghapus kode kerusakan pada sepeda motor Honda Revo PGM-FI.

Diffraction Patterns

Computer programs are now available in various laboratories for the indexing and simulation of transmission electron diffraction patterns. Although these programs address themselves to the solution of various aspects of the indexing and simulation process, the ultimate goal is to perform real time diffraction pattern analysis directly off of the imaging screen of the transmission electron microscope. The program to be described in this paper represents one step prior to real time analysis. It involves the combination of two programs, described in an earlier paper(l), into a single program for use on an interactive basis with a minicomputer. In our case, the minicomputer is an INTERDATA 70 equipped with a Tektronix 4010-1 graphical display terminal and hard copy unit.A simplified flow diagram of the combined program, written in Fortran IV, is shown in Figure 1. It consists of two programs INDEX and TEDP which index and simulate electron diffraction patterns respectively. The user has the option of choosing either the indexing or simulating aspects of the combined program.
