STARTING VALVE DRIVING DEVICE USING A PICKUP SENSOR, CAPABLE OF EFFECTIVELY STARTING AN ENGINE BY DRIVING A STARTING VALVE WITH CALCULATING A STARTING AIR SPRAY TIMING EXACTLY

摘要

PURPOSE: A starting valve driving device using a pickup sensor is provided to effectively operate a stop, reverse rotations, and restarting operations by consistently recognizing a crank angle after a first starting of an engine.;CONSTITUTION: A starting valve driving device using a pickup sensor comprises trigger rings, marker pickup sensors, gear pickup sensors, controllers, a pressure switch block(60), and a solenoid valve block(70). The trigger ring determines a range of a present crank angle for first-starting an engine. The marker pickup sensors recognize inner markers of the trigger rings. The gear pickup sensors determine a rotation of a flywheel by recognizing a gear of the flywheel. The controllers determine the present crank angle by receiving signals from the marker pickup sensors and the gear pickup sensors. The controllers determine cylinders supplying starting air for a starting, a pause and reverse rotations. The pressure switch block transfers a command of user to the controllers. A solenoid valve of the solenoid valve block supplies pilot air by receiving the signals from the controllers.;COPYRIGHT KIPO 2012
