Title: Martin Kiesner: Innovator in Combustion Engine Technology

Introduction

Martin Kiesner is a notable inventor based in Weinstadt, Germany. He has made significant contributions to the field of combustion engine technology, holding 2 patents that showcase his innovative approach to engine operation and fuel management.

Latest Patents

Kiesner's latest patents include a method for starting a combustion engine with a starter apparatus. This method involves feeding a fuel/air mixture to the engine via an intake channel, which is ignited by a spark plug. The combustion drives the piston downward, which in turn rotates the crankshaft. The fuel system features a fuel channel that opens into the intake channel, with an electric fuel valve that remains open in its currentless state. This valve closes only when an operating voltage is applied. An electronic control unit actuates the fuel valve and triggers the ignition spark, utilizing energy from a generator to supply power to the control unit, fuel valve, and ignition device. To prevent excessive enrichment of the fuel/air mixture during starting, the energy generated at the beginning of the crankshaft's rotation is used to close the fuel valve before the ignition spark is triggered.

Another significant patent by Kiesner relates to a method for adapting the composition of a mixture of fuel and combustion air. This method supplies the mixture to a combustion chamber of a mixture-lubricated combustion engine in a work apparatus. The fuel is metered by a controlled fuel valve during the engine's normal operating state. To adapt the mixture composition, the engine is shifted into a special operating state that differs from the normal one. After starting, the engine operates in a specific rotational speed range for a predetermined time, after which the special operating state is initiated by a user action.
