Abstract
PURPOSE: To acquire fuel saving while driving automobile by changing over automatically to neutral.
CONSTITUTION: Neutral valve 7 is provided in speed changing mechanism 4 which has automatic speed changing mechanism 1W3 etc. in it. Micro computer 13, induced by signals from accelerating sensor 9 which detects releasing of accelerator 8 and from neutral forbidding condition sensor 10 which detects running condition, actuates neutral valve 7 via driving circuit. Speed changing mechanism 4 becomes in a state of neutral by operation of neutral valve 7 and breaks connection between engine and driving wheel. By this, neutral running can be get automatically, and consequently, at the time running in reduced speed with released accelerator and etc., revolution number of engine can be kept in low and thus can save fuel.
