Direct and Common-Rail Systems Awareness and Overview

Course number: SV10912-11B1

The number of diesel engines in cars and light-duty trucks on the road today is increasing, driven most likely by the fuel economy gained by these efficient engines. Diesel systems are becoming more refined and manufacturers will be offering these types of engines in more makes and models. Since the diesel common-rail direct injection system relies heavily on electronics to control its operation, modern diesel systems are difficult to diagnose without proper training. 

In this course, we will discuss common-rail direct injection components, as well as review how the entire system is designed and operates with detailed graphics and demonstrations. We will cover internal injector operation in detail, including nozzle types, edge filters, spill port operation, and nozzle springs. Single high mounted, low mounted and two-stage nozzle springs will also be discussed as well as fuel sac, needle lift, and nozzle hole arrangement.
