An experimental investigation of hybrid powertrain for hand held tools with focus on the combustion engine
Experimental work on a parallel hybrid powertrain system with a focus on the combustion engine . The system consists of a small 4 stroke combustion engine and a permanent magnet BLDC motor to drive a handheld tool . The combustion engine should be able to operate in the best operation line strategy for higher efficiency. Four main changes in the combustion engine of the tool will be performed:
- electronically controlled battery powered ignition,
- electronically controlled carbuteror systems (M tronic ),
- throttle less engine operation and
- emission aftertreatment.
The final results will be compared in terms of overall system efficiency , spesific emissions and cost.
