Because of environmental pollution, forces the automotive industry constantly reduced emissions requirements legislated by the authorities. Improved techniques for engine control are a must for bringing down emissions. The use of an Exhaust Gas Recirculation (EGR) reduces NOx emissions significantly. Faulty EGR valves affect the emissions negative and therefore needs to be eliminated. It is possible to create malfunctions on the EGR valve by modifying the software of the control unit (ECU), but it does not create realistic malfunctions. The problem by modifying the software is that flags and various parameters are set to confirm the malfunction of the ECU. To create actual failure of the EGR valve an external tool to modify the control signal is needed. The project's main objective is on a flexible way creating malfunctions on the EGR valve in a truck engine. By investigating engine behavior in a realistic and credible way, one can eliminate malfunctions on the EGR valve. The aim was achieved by a model that has been developed that can, using electronics and a microprocessor read and create a control signal. The electronic circuit is controlled by the microprocessor, which can modify the signal and create malfunctions in the form of a slow valve "slow-response". A graphical user interface is used to change and influence the error signal. The circuit with the microprocessor is placed safely in a box to both protect and preserve the components. Simulation of Slow response has resulted in an incorrect operated valve being created. Using two different methods a Slow-response can be created. One method is a delay in time, which occurs when the new position is given, the second method is a ramp function when the control signal is gradually increasing. The software can also create an error that mimics a stuck valve of a fixed value. With the above listed methods it is possible in theory to find unknown malfunctions on the EGR valve that influence emissions negatively.

Experimental teaching techniques and classroom facilities have recently been brought into use at The Woodlands School, to train the category of children resident in The School who can be described as moderately retarded. An exploratory study has been conducted and the main features of this programme set out, to ascertain whether the progress of the children is significant and whether this has had any influence on their family acceptability. With the cooperation of The Woodlands School Staff, and from the parents, a sample group of boys, aged eight to seventeen, was chosen for study. The boys are resident at the institution and attend the special training classes; their parents reside within a thirty-five mile distance from Vancouver. A Social Competency Rating Scale was adapted from one utilized in a San Francisco study and applied to two specific times, (a) before the child received training in the special training classes and, (b) after at least one year's training. This scale permits an assessment of the degree of each child's progress in social competency. A second rating scale, designed to assess the degree to which parental acceptability of the child was influenced by the training and its results, was applied by utilizing a projective interviewing technique. It was found that the social competency of the sample group of boys has improved considerably; coincident with this, there has also been an opening up of areas of knowledge and experience which are stimulating the children to more constructive use of their time, and giving them reward through greater enjoyment of living. Parental acceptance of the children has noticeably increased. The review suggests that more inclusive services, including medical diagnostic and social work counselling, should be made available to parents of retarded children. Residential training facilities should also be extended to non-metropolitan areas of the province. / Arts, Faculty of / Social Work, School of / Graduate
