Description:
In Udo Mannek's book "Heißluftmotoren IV" (Neckar-Verlag
Villingen-Schwenningen; 1998 ISBN: 3-7883-065-3), I found a comprehensive
chapter by Sven Gütte on his master
craftsman's examination project "GT01". Meanwhile, I had acquired a
lathe. Material availability necessitated several changes to the project.
Eventually, I did away with the idea of using a ring burner running on lighter
gas because temperature-induced tension in the glass made the top of the test
tube crack repeatedly . Both cylinders are now in a horizontal position and the
engine is powered by an alcohol burner. A switch lets me select if I want to run
the motor in the base as a motor or as a generator. As a generator, it provides
power to a 10 mm LED, which illuminates the gearbox. When the generator is
turned on, engine load increases due to the electrical load and losses. This is
reflected by the rpm dropping to 520.
