X.4215 X.1402 X.3374 The design of this equipment has been influenced solely by considerations of "performance" and a serious endeavour has been made to produce a system which will fulfil its purpose under the most arduous and varied conditions. The question of control of the dynamo output has, in particular, received very thorough attention, and, whilst additional apparatus has been incorporated, the resukts obtained fully justify the extra cost. In no case has any device been adopted which it has been thought would diminish the reliability of the equipment as a whole, or increase the amount of attention required to keep it in good order. The system is of the "two unit" type, that is to say the starting is performed by a specially designed motor, and a separate machine is provided for charging the accumulator. This arrangement has been adopted because, up to the present, the "single unit" system has not been found very suitable for large engines, though for light cars, it is most satisfactory. The Bleriot-Phi equipment is intended for the highest class of cars, which, as a rule, are fitted with large engines. In the following description, each part of an equipment will be described separately. The "Bi-Compound" Dynamo. This is a two pole machine of very simple and robust construction, and is illustrated in Fig.1. A section is Contd. | ||
