ABSTRACT:
An ignition timing controller for a gasoline engine on an automobile or the like. The apparatus comprises a thermo sensor actuated in response to variation in an engine cooling water temperature and a negative pressure delay valve. The thermo sensor has a first port connected to an advancer port opening to a carburetor and located near a throttle valve, a second port connected to an advance control port opening into the carburetor and located above the advancer port and a third port connected to a negative pressure chamber of a vacuum advancer. When the water temperature is at a predetermined value or lower, the first and third ports of the thermo sensor are connected with each other through the interior of the thermo sensor. When the water temperature becomes higher than the predetermined value, the first and second ports of the thermo sensor are connected with each other through the thermo sensor. The negative pressure delay valve is divided by a partition into two chambers, one of which is connected to a passage which connects the advancer port of the carburetor and the thermo sensor and the other of which is connected to a passage which connects the thermo sensor and the negative pressure chamber of the vacuum advancer. The partition is provided with an orifice and a check valve adapted to permit fluid flow only in a direction from the one to the other chamber of the negative pressure delay valve. A throat is provided in the second port of the thermo sensor. Thus, when the water temperature is at or lower than a predetermined value, ignition timing is advanced, whereby good performance of the engine is maintained. When the water temperature is higher than the predetermined value, the distributor advance angle is determined according to the opening of the throttle valve and a deep press-down and instant release of the accelerator pedal will not cause advance of ignition timing.
