Formatted abstract To improve the engine performance, this dissertation aims at developing a framework
of engine control and optimisation. The engine control algorithm has to be developed
to fully utilise the technical advances in sensors. The engine control technologies on
the market today have been conservatively designed for safety and reliability concerns.
This strategy sacrifices the peak efficiency of the engine for the safety margin of operation.
The current dissertation proposes online optimization for engine control. The
objective is to include continuos real time engine tuning while maintaining its safety
and reliability.
To understand why the engine controller is a key apparatus to more efficient engine
operation, the basic internal combustion engine theory is presented in the thesis. The
state of the art and advanced engine control technologies are described in this thesis to
outline the research challenge.
The main objective of this research is to develop a framework for engine control and
optimization. The main tasks are engine control optimization and engine controller
design. To achieve the objective, a novel control system concept is proposed. The
advancement in sensor technology allows production of low cost torque sensor which
opens up an area for torque sensor feedback control.
The concept was tested in simulation and the result shows improvement of 5% to 10%
in engine efficiency. It was further being implemented into a rapid prototype for enginedynamometer
testing. The experimental result shows similar improvement in engine
efficiency of 2% to 7%.
