Starter control system for internal combustion engine with electric starter and kick starter measures battery voltage and disables electric starter when voltage falls below given threshold

摘要

#CMT# #/CMT# The starter motor (9) is connected to a starter relay (14). It has a connection to a further relay (12) in a starter cutout circuit (10). The relay is connected to a starter switch and a transistor (17). A sensor for battery voltage (U Bat) is connected to a switching stage (11) whose output (Out) passes to the transistor via a delay circuit (16). #CMT#USE : #/CMT# Starter motor control circuit for use with internal combustion engine. #CMT#ADVANTAGE : #/CMT# Starter motor is disabled when battery voltage drops below a threshold for a given length of time, thus avoiding complete running down of battery when cold engine is difficult to start. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a starter motor circuit with a cutout circuit operating at low battery voltage. Out : Switching stage output U Bat : Battery voltage 9 : Starter motor 10 : Starter cutout circuit 11 : Switching stage 12 : Further relay 14 : Starter relay 16 : Delay circuit 17 : Transistor.
