Title: Louis Jean Chateau: Innovator in Ignition Control Technology
Introduction
Louis Jean Chateau is a notable inventor based in Rosny-sur-Bois, France. He has made significant contributions to the field of ignition control technology, holding a total of 9 patents. His work has advanced the efficiency and reliability of ignition systems in internal combustion engines.
Latest Patents
One of his latest patents is an ignition control device with monostable elements. This device includes a voltage step-up coil with its primary winding in series with an electronic contact breaker. The contact breaker is directly controlled by a first monostable circuit, which is triggered by signals from an ignition signal generator. A comparator receives a voltage signal from a coil current transducer and compares it with a fixed voltage level, producing a square wave whose duration depends on the excess of the voltage signal above the fixed voltage level. An integrator then integrates the output of the comparator, providing a pulse duration control signal to the first monostable. Additionally, a second monostable, triggered by the generator, produces a square wave of predetermined duration. A current limiting circuit is connected to limit current in the primary winding, with all outputs connected to an OR gate that controls the primary current.
Another significant patent is an automatic spark timing device. This digital control device for an internal combustion engine ignition system includes a shaft angle digital encoder and a shaft speed digital encoder. A matrix memory, addressed by the speed digital encoder, is programmed to produce a digital output representing the required ignition angle for each speed value. A comparator connected to the angle encoder and the matrix produces an output pulse when the digital signals coincide. This system determines the shaft angles at which current flow through the ignition coil is initiated and terminated.
