Project 4 On board diagnosis of the lambda sensor
1.
Project Title On board diagnosis of the lambda sensor
2. Abstract
The lambda sensor is an essential part of the air fuel ratio control of a compression ignition
engine. Precise control of the air fuel ration is required for the proper operation of the three way
catalyst. Even small deviations can have significant effects on the amount of emissions. Therefore
the operation of the lambda sensor is often checked at regular services, but it is also possible to
detect a number of malfunctions on board.

Project Objective
Analyse a number of faults of the lambda sensor
Create a simple model of the engine to calculate an expected reading
Compare potential diagnosis approaches

Experience using simulation environments such as MATLAB/Simulink
5.
Plant descriptions and modeling requirements
A reasonable model of the air fuel ratio is required.
It does not have to account for all factors, but it should capture the most important ones.
A simple model of the exhaust and the lambda sensor is also required.
Model errors have to be considered carefully.
6.
Controller designing
This project uses a diagnosis unit, which has to be designed.
It contains a decision logic that can detect and indicate faults.
Several different approaches of different complexity have to be tested.
7.
Controller validation requirement
Validation should be based on both constructed and realistic engine cycles.
8.
Requirements of Project team, Language and Tools
A number of different work packages have to be coordinated, some of which can be
completed in parallel. MATLAB/Simulink is the most likely tool, but other choices are possible,
especially for estimating model accuracy and for signal based methods.
9.
Project evaluation standard
The project should conclude with a comparison of different methods and their effectiveness
when applied to a number of faults. The results are to be compared with theoretical
assessments and limitations of the methods, and with common practice. Ideally, the report
also gives reasons for the differences in performances, and recommendations for choosing
the right method.
