This study was conducted to obtain the results of mapping and analysis of sea trial data after maintenance of the motor lubrication and cooling system using the Engine Control Unit (ECU) so that recommendations for maintenance activities for damage control have been completed. The results of data analysis indicate that the pressure and temperature in the system return to normal in the allowable parameters tend to be the same or there is no change if repeated at the same rotation, the pressure rises and falls according to the engine speed. This data is an indicator that both system data has been successfully returned after treatment. Engineers should always write down the data in the engine journal so that if the ECU records data that is not in accordance with sea trial data, maintenance is immediately carried out to avoid further damage

   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.

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.

SHRNUTÍ Byla vyvinuta programovatelna řidici jednotka na platformě CompactRIO s programem vytvořenym v prostředi LabVIEW. Jednotka byla vyvijena jako univerzalni a byla testovana při řizeni maleho zažehoveho motoru YAMAHA YZF R6. Jednotka je dale použitelna pro zažehove motory různe koncepce, přeplňovane i nepřeplňovane. Požadavku na univerzalnost jednotky byl přizpůsoben řidici program, ktery je uspořadan ve vzajemně komunikujicich samostatnych blocich. Zařizeni je rozšiřitelne o dalši I/O moduly, což umožňuje použiti dalšich snimačů, aktuatorů nebo modulů pro komunikaci. Rozhrani pro zesileni vystupů napajejicich zapalovani a vstřikovače bylo vyvinuto pro řizeni motoru YAMAHA YZF R6. Toto zařizeni zaroveň stabilizuje napajeni snimačů motoru a filtruje jejich vystupni signaly. Članek je shrnutim procesu vyvoje řidici jednotky motoru, obsahuje přehled použitych zařizeni, seznamuje s řidicim programem a zkušenostmi z testovani na motoru.

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.
