Course Overview

CR injector technology has been at the forefront of diesel for almost 20 years. Due to tight manufacturing tolerances injectors can be susceptible to early failure from a number of external factors as well as component failure. This course will cover the operation and design of Denso solenoid, Piezo and the newer i-Art injectors. It will cover how to repair and replace internal components and the tooling requirements to do this. Finally it will cover testing the injector delivery, response time, and backleak in a non-authorised capacity.
