Summary on Grant Application Form |
|
Accurate knowledge of the hydrocarbon (HC) concentration in the cylinder of an internal combustion engine is crucial for the optimisation of fuel supply, ignition timing etc. Systems for non-intrusive optical monitoring of the HC concentration, capable of real-time electronic feedback for ignition control, have been demonstrated, but none of them is compatible with real engines. The proposed project aims to assess the feasibility of an optical probe that can offer a solution to the problem by combining the technique of optically-induced fluorescence (OIF) with an all-optoelectronic solution, which is non-intrusive, compact, lightweight, power efficient and reliable. This is based on the group's observation in previous work that the efficiency of fluorescence in commercial fuels can be substantially increased by shifting and the excitation wavelength into the deep-blue and UV spectral region. The major challenges to be addressed are the efficient coupling of the emission from a 400 nm semiconductor laser into a lightguide and the consequent design of the optical probe, taking into account constraints dictated by the established engine design.The proposed work is novel, and offers possibilities for future expansion into multi-channel techniques (optical tomography), real-time optical fingerprinting of the fuel, optical monitoring of exhaust gases, atmospheric pollution, etc.
