摘要： An intake system for an internal combustion engine comprises an intake pipe structure connected through an intake manifold to cylinders of the engine, a fuel injection valve for injecting fuel into the intake pipe structure to form an air-fuel mixture, a throttle valve disposed in the intake pipe structure, and a baffle plate disposed in the intake pipe structure between the fuel injection valve and the throttle valve for promoting fuel atomization. The baffle plate has a surface which faces the fuel injection valve with a predetermined distance from the latter in order that the fuel injected from the fuel injection valve may impinge on the surface, and an outer edge spaced from an inner wall surface of the intake pipe structure to define a mixture passage therebetween. The baffle plate is made of a ceramic material having positive resistance-temperature characteristic and definite Curie point and adapted to be heated when electric current is applied thereto, so that it may be maintained at a temperature appropriate to cause preferable atomization of the fuel impinged on the baffle plate surface.

摘要： An ignition timing control system including a counter into which is introduced a data generated from a memory and indicative of the proper ignition advance corresponding to the operating conditions of an engine and the decrement or increment of the count is made in synchronism with predetermined degrees of rotation of the engine to determine the desired ignition timing. When knock occurs n times per m times of engine explosion stroke, the knocking ratio n/m is computed and the content of the counter is corrected in response to the value of the knocking ratio to correct the ignition timing. The value of m for the knocking ratio n/m is variable in accordance with the engine operating conditions.

摘要： An ignition timing control system for internal combustion engines includes a knock detecting circuit for determining the presence or absence of the knocking in response to a signal from a knock detector, and includes a correction advance computing circuit for computing a correction value of ignition advance thereby to retard the ignition timing by a predetermined angle when the knock is present and to advance the ignition timing when the knock is absent. A further battery is provided to supply electric power to the correction advance computing circuit even after a key switch associated with a main battery for supplying power to the ignition timing control system has been turned off. Hence, the correction advance computing circuit memorizes the computed advance correction value corresponding to a knock condition of the engine just prior to the turn-off of the key switch and the memorized advance correction value is made available in a subsequent operation of the ignition timing control system.
