Gasoline Direct Injection (GDI) Diagnostic Online Course

Welcome to Mechanicourse!

In this course we explain everything about Gasoline Direct Injection (GDI) Fuel System Operation and Diagnostics.

Modern vehicles are becoming more advanced every year, and GDI technology is now widely used in gasoline engines because of its improved fuel efficiency, better engine performance, reduced emissions, and faster throttle response. Understanding how this system works is essential for today’s automotive technicians and diagnostic specialists.

In this course, you will learn the complete operation of the GDI system from both theoretical and practical perspectives, so we have a lot of practical lectures in this course which helps you understand the diagnostic even better and deeper.

Here is what you will learn in this course:

• Gasoline Direct Injection (GDI) Introduction.

• GDI Engine advantages and disadvantages.

• GDI and Port injection fuel system comparison and an overview to Dual Injection System.

• GDI Fuel System Components Introduction.

• GDI High-Pressure Pump operation, removal, installation & diagnostic.

• GDI Injectors operation, diagrams & diagnostic.

• GDI Fuel Pressure Control Valve operation, diagrams & diagnostic.

• Fuel Rail Pressure Sensor operation, diagrams & diagnostic.

• GDI Fuel system wiring diagrams analysis.

• Identifying the wiring and connectors on the car and testing the components and circuit with a multimeter.

• GDI System Diagnostics with Scan Tool

• Diagnosing the GDI System with oscilloscope including reading and analyzing the waveforms of GDI injectors (Voltage & Current waveforms) and waveform of the fuel pressure control valve.
