TLDR
In this article, a suction motor is connected to the timing mechanism to produce spark advance and spark retard when moved in one direction and in the opposite direction, respectively, and the motor comprises a housing having a flexible diaphragm dividing the housing into a pair of chambers and is moved by a speed responsive valve connecting the pressure in the intake manifold to one or other chambers.Abstract:
A spark timing control for an internal combustion engine. A suction motor is connected to the timing mechanism to produce spark advance when moved in one direction and spark retard when moved in the opposite direction. The motor comprises a housing having a flexible diaphragm dividing the housing into a pair of chambers and is moved by a speed responsive valve connecting the pressure in the intake manifold to one or the other chambers.read more
