Abstract
A centrifugal governor for fuel injected internal combustion engines is proposed, especially an idling and final rpm governor for Diesel vehicle engines, in which the sudden emission of smoke upon starting of a heavily loaded engine is prevented. The improved governor comprises an additional idling spring secured on a force transmitting lever which is acted upon by the main control spring and by means of which additional idling spring in the idling setting of the service lever the restoring force of the idling spring on a portion (b) of the idling sleeve path (a) is amplified. This force of the additional idling spring is, however, made at least partially ineffective by a thrust member when the service lever is pivoted into the full-load position. Further, there is disclosed a governor which is equipped with an additional idling spring which comprises two additional springs, the aforementioned thrust member being arranged to act only upon the second additional spring, while the first additional spring remains coupled with the governor sleeve via a connecting member in order to improve starting.
