Fuel Injection & Combustion Analysis - One Day (£200 per delegate)

Topics

Fundamentals of Combustion Chemistry: How combustion chemistry influences power, efficiency, and emissions – Stoichiometry and air-fuel ratio basics – The effects of rich and lean mixtures on engine operation
Fuel Injection Strategies: Overview of injection types: port, direct, GDI, sequential – Advantages and challenges of each system – Common failure modes and symptoms in modern injection systems
Interpreting Live Data and Sensor Signals: Understanding fuel trims and what they reveal – Reading and analysing oxygen sensor signals (narrowband and wideband) – Air-fuel ratio diagnostics and what to expect under different conditions
Diagnosing Fuel and Combustion Issues: Identifying rich and lean running conditions – Injector balance and cylinder efficiency testing – Detecting misfires and uneven combustion through data analysis
Using Diagnostic Tools Effectively: Applying scan tools for mixture and injector diagnostics – Oscilloscope techniques for analysing injector and ignition events – Using exhaust gas analysers to evaluate combustion integrity and emissions
Hands-On Diagnostic Exercises: Practical diagnosis of fuelling and combustion faults – Live data interpretation and waveform capture – Verifying repairs and confirming combustion quality

Course Summary

Building on foundational knowledge of vehicle diagnostics, Fuel Injection & Combustion Analysis equips technicians with the practical skills and theoretical understanding of how fuel and air interact in the combustion chamber and is key to diagnosing and repairing modern engines efficiently. This course explains the fundamentals of combustion chemistry, explores common and advanced fuel injection systems, and teaches practical methods to assess and optimise combustion integrity using everyday workshop tools.
The course is designed for automotive technicians, apprentices, and workshop professionals aiming to build diagnostic efficiency and accuracy using industry-standard scan tools. Fuel Injection & Combustion Analysis provides essential techniques for mastering diagnosis and reducing time to repair.
​On completion, you will receive a certificate of attendance which can be used towards Continuing Professional Development (CPD) credits.
All courses designed and taught exclusively by Graham Stoakes AAE MIMI MSET QTLS

Requirements

There are no formal entry requirements for this course, however, you should currently be working in the automotive industry as a vehicle technician or similar. The attendance of the other Automotive Testing & Diagnosis courses prior to undertaking this training will reinforce concepts used in diagnostic strategies.

This course is recommended for progression onto further diagnostic training.
​
This course is a mixture of theory and practical and will require suitable clothing for conducting workshop activities. ​Safety boots are required for all technical work shop based activities. You will be unable to participate in the course if you do not wear the appropriate PPE.

We reserve the right to exclude a candidate who we suspect is under the influence of alcohol or drugs (the candidate may also need to make alternative arrangements for onward journeys).
