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.

   Conventionally diesel engines are controlled in open loop with maps based on engine speed and throttle position wherein fuel quantity is indirectly fixed using the rail pressure and injection duration maps with engine speed and throttle position as the independent variables which are measured by the respective sensors. In this work an engine control unit (ECU) software architecture where fuel quantity is directly specified in relation to the driver demand was implemented by modifying the control logic of a throttle position based framework. A desired fuel quantity for a given engine speed and throttle position was mapped from base line experiments on the reference engine. Injection durations and rail pressure required for this quantity was mapped on a fuel injector calibration test bench. The final calculation of injection duration in the new architecture is calculated using the fuel injector model. This enables determination of fuel quantity injected at any moment which directly indicates the torque produced by the engine at a given speed enabling smoke limited fuelling calculations and easing the implementation of control functions like all-speed governing.

The article discusses the issues of increasing the efficiency of the classification process of cards of electronic control units of a car engine. The analysis of the existing software for editing calibration tables in electronic engine control unit, which has tools for determining calibrations and data recognition, was carried out. The limits of use of such software products are conditioned by a small number of specified classes of calibration tables and low data processing speed. The analysis of testing results of classification methods using spectral decomposition demonstrated that a system based on this method requires complex transformations of the results of spectral decomposition. The use of spectral decomposition as a solution of the classification problem is possible if some characteristics of the input data are determined and used as data for classification. It was developed a data classification algorithm that uses characterizers to compute a clearly identified characteristic of the input matrix. The software package for the implementation of the developed algorithm was carried out by using the .NET Framework and the C # programming language. The testing of the classification system performance performed by using the developed software system on a small sample of maps. The results of preliminary testing showed that the system determines correctly the class of the provided card after training. Further testing on the Mercedes-Benz Bosch EDC16C31 / EDC16CP31 car block family showed that in cases of a large number of training images, the result meets the requirements. The performed tests allowed us to determine the optimal number of images for training and the time required for this.

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.
