NEW OIL ENGINE

Aucklanders’ Invention FAVOURABLE REPORT IxumJsb, August M Professor 8. J. Davies, King’s ©allege, London, reporting upon the plans of the oil engine designed by the EdllnStewart Company, New Zealand, «x--pects that the engine will give service in high speed, stationary, and road and raU transport, and with adaptations is comparable to the success achieved by the Junkers Aircraft Company’s design, which Professor Davies takes an the basis of comparison. The inventors of the Edlin-Stewart engine are two Auckland engineers. Messrs. G. 8. Edlin and H. H. Stewart. Mr. Edlin started his experiments as far back as 1914, and in 1926 he was joined by Mr. Stewart A company was formed in Auckland to exploit the patent abroad, and the chairman of directors is Mr. C. F. Bennett. The engine is of the twostroke expansion type, applicable to both petrol and crude oik It li comparatively simple in design and operation. The bal ance and. exceedingly smooth action or the Edlin-Stewart engine have impressed notable engineering authorities In Greai Britain and the United States of America. Representatives of the company visited America with a petrel engine abom eighteen months ago, and were euecessftv fn enlisting the Intereet of the Chrysler Corporation, Owing to the high cost of developmental work abroad, and the fact that additional patents were pending, it was decided that the Diesel engine be constructed In Auckland under the supervision of the company’s engineer# and executives. This work was satisfactorily carried out by the Johnson Engineering Company. This Diesel engine was taken to Englund in November last, and recognition of the valuable features embodied in It has been accorded by eminent authorities. Dr. Davies, of the King’s School nf Engineering, London, and the technical experts of the Salmson Engine Co., Ltd., are at present engaged on finalising the design of a commercial engine, based on the Edlin-Stewart principles. In the first instance production under royalty will be undertaken by two well-known engineering firms with a market for single cylinder units. Development of multicylinder engines will then follow.
