Intelligent Engine Management System for Small Handheld Low Emission Engines 2009-32-0019

In the handheld industry the carburetor controlled 2-stroke engine is still the mostly used power source. The current carburetor as a fixed geometric and hydraulic system is not capable of compensating varying fuel specifications. Electronic engine management systems offer the adjustment of varying ambient conditions and fuel qualities. State of the art systems of common vehicle applications use various sensors and actuators which increase the complexity and the costs of the engine. A smart alternative is an engine control based upon processing of already existing information in a small handheld engine. This paper presents the concept, the configuration and the design parameters of such a system.
