Title: Franz Mandl: Innovator in Engine Technology
Introduction
Franz Mandl is a notable inventor based in Fellbach, Germany. He has made significant contributions to the field of engine technology, holding a total of 3 patents. His work focuses on improving ignition systems and enhancing the functionality of internal combustion engines.
Latest Patents
One of his latest patents is an ignition device for a two-stroke engine. This invention relates to a system that triggers an ignition spark at a spark plug using an ignition generator. The generator includes a magnet wheel with two permanent magnets and a magnetic yoke that carries a charging coil. This coil charges an ignition capacitor, along with a primary and secondary coil connected to the spark plug. The design ensures that a voltage is induced in the coils with each passing magnet, allowing for the ignition capacitor to discharge via a switch element. To prevent unwanted ignition at the bottom dead center of the piston, a device is included to reduce the voltage at the spark plug.
Another significant patent is an arrangement for identifying a switching position of a switch on an internal combustion engine in a handheld work apparatus. This invention provides an energy source for powering an inductive electrical load, which can be switched on and off via a controller. The switch is placed in a voltage branch parallel to the inductive load, where a zener diode is also connected. The zener diode's activation is dependent on the switch's position, allowing for the amplitude of the switch-off voltage to indicate whether the switch is closed or open.
