أثر الحالة الفنية لمنظومات التحكم الإلكتروني في أداء محركات السيارات الحديثة

Abstract EN

Automotive technology has evolved in recent decades, and manufacturers have used the latest electronic systems that achieve safety, comfort, better performance, and high economic performance, and to ensure that harmful emissions are within the permissible minimums.

To achieve the previous goals, motor systems are provided with sensors that permanently measure the variables that affect the performance of the engine.

These variables are then sent in a very short time to an electronic control unit(ECU) that works to process and analyze these signals quickly and accurately.

The results are converted into operational signals and sent to different actuators to reach the best possible performance of the engine.

The research aimed to study the changes that will occur in the performance of automobile engines as a result of changing the technical condition of the sensors.

Four test cars were selected for testing using the Diagnostic Program System (GDS) and the AutoHexII scanner.

As a result of the experimental work, the importance of maintaining the technical condition of the components of the electronic control system was shown, the important role that the sensors play and the extent of the impact of their technical condition on performance and economics, which requires the need to monitor the technical condition of all sensors of control systems.
