Abstract

On the basis of small hybrid powertrain investigations in hand-held power tools for fuel consumption and emissions reduction, the prototype hybrid configuration of a small single-cylinder four-stroke internal combustion
engine together with a brushless DC electric motor is built and measured on the testbench in terms of efficiency and emissions but also torque and power capabilities. The onboard energy storage system allows the combustion engine electrification for controlling the fuel amount and the combustion
behavior while the electric motor placement instead of the
pull-start and flywheel allows for start-stop of the system and
load point shifting strategy for lower fuel consumption. The
transient start-up results as well as the steady-state characterization
maps of the system can set the limits on the fuel consumption reduction for such a hybrid tool compared with the baseline combustion-driven tool for given load cycle characteristics.
As a next step, the data will be used for defining the energy storage system capacity and technology based on the application.
