IDLING CONTROLLER FOR ENGINE

摘要

PURPOSE:In a car engine to prevent the lowering of the idling during the driving of an auxiliary machine, by increasing the fuel at the fuel temperature rise through a temperature sensitive member which expands/shrinks with the fuel temperature. CONSTITUTION:When the auxiliary machine is driven to increase the idle load, the negative pressure is led into a negative pressure chamber 4 to displace the diaphragm 3 against a spring 10 until contacts against the stopper 5B thus to project the operating rod 2B through an operating rod 2A and a temperature sensitive member 13 thereby the fuel is increased to prevent the lowering of the idling even at the driving of the auxiliary machine. While when operating with high speed and high load for long term then returning to the idling, the temperature in the engine room is high thereby the wax 16 in the temperature sensitive member 13 will expand to project the plunger 17 thus to push the operating rod 2B by that stroke. Consequently the reduction of the fuel supply due to the high temperature or the lowering of the idling can be prevented.
